1. Which type of white blood cell is primarily responsible for engulfing and digesting pathogens through phagocytosis?

•          Macrophage

•          Red blood cell

•          Platelet

•          Neuron
Explanation: Macrophages are specialized immune cells that engulf and digest pathogens, cellular debris, and other foreign material through a process known as phagocytosis. This function makes them a key component of the body's innate immune response, providing a rapid, non-specific defense against infection. In addition to destroying pathogens directly, macrophages also help activate other parts of the immune system by presenting antigens to lymphocytes.

2. Match each function with the corresponding body system.

•          Stores minerals such as calcium and phosphorus: Skeletal system

•          Produces and transports urine out of the body: Urinary system

•          Detects and interprets sensory information from the environment: Nervous system

•          Facilitates the exchange of oxygen and carbon dioxide in the lungs: Respiratory system

•          Enables the body to fight off infection: Immune system
Explanation: The skeletal system serves as a mineral reservoir, storing calcium and phosphorus that can be released into the bloodstream as needed. The urinary system filters waste from the blood and transports the resulting urine out of the body, while the nervous system processes sensory input from the environment in real time. The respiratory system handles gas exchange in the lungs, and the immune system works continuously to identify and neutralize infectious threats.

3. Which two conditions are of particular concern for a pregnant woman with poorly controlled gestational diabetes and a sedentary lifestyle? (Choose 2)

•          Preeclampsia

•          Excessive fetal birth weight (macrosomia)

•          Common cold

•          Seasonal allergies
Explanation: Poorly controlled gestational diabetes significantly increases the risk of preeclampsia, a condition marked by dangerously high blood pressure during pregnancy. Elevated blood sugar levels also cause the fetus to receive excess glucose, often resulting in macrosomia, or an unusually large birth weight, which can complicate delivery. Both conditions require close medical monitoring throughout the pregnancy to protect the health of both mother and baby.

4. A veterinary technician was bitten by a stray dog of unknown vaccination status. Which intervention offers the most reliable protection against rabies?

•          Washing the wound with soap and water only

•          Receiving post-exposure rabies vaccination promptly

•          Applying an antibiotic ointment

•          Taking an over-the-counter pain reliever
Explanation: Rabies is a nearly always fatal viral infection once symptoms appear, making prompt post-exposure vaccination the single most critical intervention after a potential exposure. While wound cleaning is an important first step, it does not eliminate the risk of the virus establishing infection on its own. Timely vaccination stimulates the immune system to produce protective antibodies before the virus can reach the nervous system.

5. Which changes occur in the body as a result of sustained aerobic training over several months? (Choose 3)

•          Increased stroke volume of the heart

•          Greater capillary density in muscle tissue

•          Improved VO2 max (maximal oxygen uptake)

•          Decreased number of mitochondria

•          Reduced blood plasma volume
Explanation: Sustained aerobic training increases the heart's stroke volume, allowing it to pump more blood with each beat and improving overall circulatory efficiency. This is accompanied by a greater density of capillaries within trained muscle tissue, which enhances the delivery of oxygen and nutrients during exercise. Together, these adaptations contribute to an improved VO2 max, reflecting the body's increased capacity to take in and utilize oxygen during physical exertion.

6. Which health consequences are associated with excessive sedentary behavior, such as prolonged sitting? (Choose 3)

•          Increased risk of blood clots

•          Poor posture and back pain

•          Improved metabolic rate

•          Elevated triglyceride levels

•          Enhanced circulation
Explanation: Prolonged sitting slows blood flow in the legs, increasing the risk of blood clots forming in the deep veins. Extended periods in a seated position also place strain on the spine and supporting muscles, frequently resulting in poor posture and chronic back pain. Sedentary behavior additionally disrupts normal lipid metabolism, often leading to elevated triglyceride levels over time.

7. When performing hands-only CPR on an adult, at what rate should chest compressions be delivered?

•          40-60 compressions per minute

•          100-120 compressions per minute

•          150-170 compressions per minute

•          20-30 compressions per minute
Explanation: Current guidelines recommend delivering chest compressions at a rate of 100 to 120 per minute during hands-only CPR to maintain adequate blood flow to vital organs. This rate closely mirrors the tempo needed to keep blood circulating effectively until professional medical help or an AED becomes available. Maintaining consistent depth and rate throughout compressions significantly improves the likelihood of a successful outcome.

8. Which practices are recommended for preventing cavities and tooth decay? (Choose 3)

•          Limiting frequency of sugary snacks

•          Drinking plenty of water throughout the day

•          Using a fluoride mouth rinse

•          Brushing teeth immediately with excessive force

•          Avoiding dental cleanings to save time
Explanation: Limiting how frequently sugary snacks are consumed reduces the number of acid attacks on tooth enamel throughout the day, which is often more important than the total quantity consumed. Drinking water regularly helps rinse away food particles and supports saliva production, which naturally protects teeth. A fluoride mouth rinse provides an additional layer of protection by further strengthening enamel against decay.

9. Which stage of the sleep cycle is most closely associated with memory consolidation and processing of the day's learning?

•          Stage 1

•          REM sleep

•          Stage 3

•          Stage 2 only
Explanation: REM sleep plays a particularly important role in memory consolidation, helping the brain process and organize information acquired throughout the day. During this stage, the brain shows activity patterns similar to wakefulness, which is thought to support the integration of new memories with existing knowledge. Disruption of REM sleep has been associated with difficulties in learning and emotional regulation.

10. What is the recommended amount of sleep per night for older adults aged 65 and above?

•          3-4 hours

•          7-8 hours

•          10-12 hours

•          13-14 hours
Explanation: Older adults aged 65 and above are generally recommended to get 7 to 8 hours of sleep per night, similar to younger adults, though sleep patterns often become lighter and more fragmented with age. Adequate sleep in this age group supports cognitive function, mood stability, and immune health. Sleep disturbances in older adults should not simply be dismissed as a normal part of aging, as they can often be addressed through targeted interventions.

11. Match each function with the nutrient category most responsible for it.

•          Provides essential fatty acids the body cannot produce on its own: Fats

•          Breaks down into simple sugars during digestion: Carbohydrates

•          Contains nitrogen, distinguishing it from other macronutrients: Protein

•          Is the primary structural component of enzymes: Protein

•          Can be classified as simple or complex: Carbohydrates

•          Includes saturated, unsaturated, and trans forms: Fats
Explanation: Fats supply essential fatty acids that the body cannot synthesize on its own and must obtain through diet, and they exist in several forms, including saturated, unsaturated, and trans fats. Carbohydrates are broken down during digestion into simple sugars and can themselves be classified as simple or complex depending on their molecular structure. Protein is unique among the three macronutrients in that it contains nitrogen, which is essential for forming enzymes and other structural components of the body.

12. Which measurement reflects the proportion of body weight that is composed of fat versus lean tissue?

•          Body composition (body fat percentage)

•          Basal metabolic rate

•          Glycemic load

•          Waist-to-hip ratio only
Explanation: Body composition analysis measures the proportion of a person's total weight made up of fat mass compared to lean tissue such as muscle, bone, and water. This measurement provides a more nuanced picture of health than weight or BMI alone, since it accounts for the distribution of tissue types. Tracking changes in body composition over time can help individuals and clinicians better assess the effectiveness of diet and exercise interventions.

13. Why might a nutritionist recommend replacing white bread with 100% whole wheat bread?

•          It contains fewer nutrients

•          It retains the bran and germ, providing more fiber

•          It has a longer shelf life

•          It contains more refined sugar
Explanation: Whole wheat bread retains the bran and germ layers of the wheat kernel, which are removed during the refining process used to make white bread. These retained layers provide significantly more dietary fiber, along with additional vitamins and minerals such as B vitamins and iron. The added fiber content also supports more stable blood sugar levels and improved digestive health compared to refined white bread.

14. Which of the following snack choices provides the most sustained energy without a rapid blood sugar spike?

•          Hummus with raw vegetable sticks

•          A can of soda

•          A chocolate bar

•          Cotton candy
Explanation: Hummus paired with raw vegetable sticks combines plant-based protein and fiber, both of which slow the digestion and absorption of carbohydrates. This combination helps prevent the rapid spike and subsequent crash in blood sugar that is common with sugary or highly processed snacks. Choosing snacks with this kind of nutrient balance supports more consistent energy and concentration throughout the day.

15. Which food is excluded from a vegan diet but commonly included in a vegetarian diet?

•          Beef

•          Pork

•          Honey

•          Chicken
Explanation: Many strict vegans choose to avoid honey because it is produced by bees, an animal, and its harvesting can involve practices some consider harmful to bee populations. Vegetarians, however, typically do not have this restriction, since honey does not come from slaughtered animals. This distinction reflects the broader ethical considerations that often shape the boundaries of a vegan diet compared to a standard vegetarian one.

16. Sudden onset of vomiting, hives, and shortness of breath after eating tree nuts is characteristic of which type of reaction?

•          Mild food intolerance

•          Anaphylactic allergic reaction

•          Simple heartburn

•          Lactose intolerance
Explanation: The combination of vomiting, hives, and shortness of breath after consuming a known allergen like tree nuts strongly suggests an anaphylactic reaction, a severe and rapid immune response. This reaction can progress quickly and become life-threatening without immediate treatment, typically involving an epinephrine injection. Tree nuts are among the most common triggers for this type of severe allergic response, particularly in children and adults with known nut allergies.

17. What benefit is most likely to result from achieving a healthy waist circumference through diet and regular physical activity?

•          Increased risk of metabolic syndrome

•          Reduced risk of metabolic syndrome

•          Weakened cardiovascular function

•          Elevated fasting blood glucose
Explanation: Reducing waist circumference through diet and exercise specifically targets visceral fat, which surrounds internal organs and is strongly linked to metabolic syndrome. Lowering this type of fat improves insulin sensitivity and reduces inflammation throughout the body. As a result, individuals who achieve a healthier waist circumference typically see a meaningful reduction in their overall risk for conditions like type 2 diabetes and heart disease.

18. A collegiate rugby player has a BMI of 28, placing them in the overweight category, despite having a low body fat percentage confirmed by skinfold testing. What is the best interpretation of this discrepancy?

•          The skinfold test results should be disregarded in favor of BMI

•          BMI does not account for the athlete's high muscle mass

•          The athlete should reduce protein intake immediately

•          BMI is the most precise indicator of health for all individuals
Explanation: When a direct measurement like skinfold testing shows low body fat despite an elevated BMI, it strongly suggests that the individual's classification is skewed by muscle mass rather than excess fat. BMI's inability to distinguish between muscle and fat tissue is a well-known limitation, particularly relevant for athletes in strength-intensive sports like rugby. In cases where more precise body composition data is available, that information should take priority over BMI alone.

19. Which food type should always be washed thoroughly before eating raw, such as in a salad?

•          Spinach leaves

•          Raw bacon

•          Ground lamb

•          Raw duck
Explanation: Leafy greens like spinach should be washed thoroughly before being eaten raw to remove any soil, pesticide residue, or bacteria present on the surface. Raw meats, by contrast, should never be washed, as this practice increases the risk of spreading harmful bacteria to kitchen surfaces through splashing. Following the correct washing protocol based on food type is a fundamental principle of safe food handling.

20. Which of the following moments requires immediate handwashing to prevent the spread of germs?

•          After coughing or sneezing into your hands

•          Before adjusting the thermostat

•          After watching a video

•          Before turning a doorknob
Explanation: Coughing or sneezing into the hands can deposit large quantities of respiratory droplets containing viruses and bacteria, making immediate handwashing essential to prevent further spread. This is a particularly important hygiene moment during cold and flu season, when respiratory illnesses are more easily transmitted through contaminated hands. Practicing this habit consistently is one of the simplest and most effective ways to reduce the transmission of common illnesses.

21. Which of the following are recognized symptoms of generalized anxiety disorder? (Choose 4)

•          Persistent, excessive worry across multiple areas of life

•          Fatigue

•          Increased appetite for social interaction

•          Irritability

•          Difficulty controlling worry

•          Enhanced memory recall
Explanation: Generalized anxiety disorder is defined by persistent and excessive worry that spans multiple areas of a person's life, often accompanied by a noticeable difficulty controlling that worry despite trying to do so. This chronic state of heightened alertness frequently leads to fatigue and irritability, as the body remains in a prolonged stress response. These combined cognitive, emotional, and physical symptoms distinguish generalized anxiety disorder from more situational, short-term nervousness.

22. Which disorder is marked by the persistent consumption of non-food items such as dirt, chalk, or paper?

•          Pica

•          Bulimia

•          Anorexia

•          Binge eating disorder
Explanation: Pica is an eating disorder characterized by the persistent consumption of substances with no nutritional value, such as dirt, chalk, paper, or other non-food items. This condition can occur in both children and adults and may be associated with certain nutritional deficiencies, developmental disorders, or psychological factors. Because ingesting these substances can pose serious health risks, including poisoning or intestinal blockage, medical evaluation is typically warranted.

23. Which scenario best illustrates retaliation related to a sexual harassment complaint?

•          An employee receiving a routine performance review

•          A supervisor demoting an employee shortly after they reported harassment

•          A company updating its harassment training materials

•          An employee requesting time off for vacation
Explanation: Demoting an employee shortly after they file a harassment complaint is a clear example of retaliation, which is itself illegal under most workplace protection laws. Retaliation occurs when an employer takes adverse action against someone for engaging in a legally protected activity, such as reporting misconduct. Protecting employees from retaliation is essential for encouraging individuals to report harassment without fear of professional consequences.

24. A partner who threatens to reveal private, embarrassing information unless the other partner complies with their demands is engaging in which form of abuse?

•          Coercive control/psychological abuse

•          Physical abuse

•          Environmental abuse

•          Financial abuse only
Explanation: Threatening to reveal private information as a means of forcing compliance is a form of coercive control, a type of psychological abuse designed to manipulate and dominate a partner. This tactic exploits trust and vulnerability, using the threat of exposure to maintain power within the relationship. Recognizing coercive control as abuse is important, since it often operates through subtle manipulation rather than overt physical harm.

25. According to the Kubler-Ross model, which stages might a person experience after receiving a diagnosis of a chronic, life-altering illness? (Choose 5)

•          Denial

•          Anger

•          Bargaining

•          Depression

•          Acceptance

•          Amusement

•          Boredom
Explanation: While originally developed to describe the experience of terminal illness, the Kubler-Ross model is also frequently applied to the emotional process of adjusting to any chronic, life-altering diagnosis. Individuals may move through denial, anger, bargaining, depression, and acceptance as they come to terms with lasting changes to their health and daily life. These stages do not always occur in a fixed sequence and may be revisited at different points during the adjustment process.

26. Which practices can help build and maintain healthy self-esteem over time? (Choose 4)

•          Practicing regular self-compassion

•          Setting achievable, incremental goals

•          Surrounding oneself with supportive relationships

•          Constantly seeking approval from others

•          Celebrating small personal accomplishments

•          Avoiding all forms of feedback
Explanation: Practicing self-compassion helps individuals respond to their own mistakes with understanding rather than harsh self-criticism, which supports a more stable sense of self-worth. Setting achievable goals and celebrating small accomplishments along the way reinforces a sense of competence and progress. Surrounding oneself with supportive relationships further strengthens self-esteem by providing consistent encouragement and a sense of belonging.

27. Which characteristics contribute to the high potential for abuse associated with prescription stimulants like Adderall? (Choose 4)

•          They increase focus and energy

•          They are widely prescribed for ADHD

•          They can produce a euphoric high at higher doses

•          They have no impact on the cardiovascular system

•          Tolerance can develop with regular non-medical use
Explanation: Prescription stimulants like Adderall are widely prescribed for ADHD, which increases their availability and the potential for misuse among individuals without a legitimate medical need. Their ability to increase focus and energy makes them appealing for non-medical use, particularly among students seeking to enhance academic performance. At higher doses, these stimulants can produce a euphoric effect, and regular non-medical use can lead to the development of tolerance and dependence over time.

28. Match each substance with the effect it has on the body.

•          Produces a warm, sedative sense of pain relief: Opioids

•          Increases heart rate and can cause paranoia at high doses: Methamphetamine

•          Slows reflexes and impairs short-term memory: Marijuana

•          Suppresses the respiratory drive at high doses: Opioids

•          Can cause severe dental damage with long-term use: Methamphetamine
Explanation: Opioids produce a sedative sense of pain relief but carry a serious risk of suppressing the respiratory drive at high doses, which is the primary cause of opioid-related overdose deaths. Methamphetamine, as a powerful stimulant, increases heart rate and can cause paranoia at high doses, along with well-documented long-term dental damage from chronic use. Marijuana affects the body differently, primarily slowing reflexes and impairing short-term memory rather than acting as a strong stimulant or depressant.

29. Which strategies can help reduce stress associated with major life transitions, such as starting a new job? (Choose 3)

•          Establishing a new daily routine

•          Seeking support from friends or mentors

•          Avoiding all social interaction during the transition

•          Setting realistic short-term expectations

•          Overcommitting to new responsibilities immediately
Explanation: Establishing a new daily routine helps create a sense of stability and predictability during a period of significant change, which can reduce feelings of overwhelm. Seeking support from friends, family, or mentors provides both emotional reassurance and practical guidance during the adjustment period. Setting realistic short-term expectations, rather than pressuring oneself to master a new role immediately, allows for a more sustainable and less stressful transition.

30. Which of the following are common cognitive symptoms of chronic stress? (Choose 4)

•          Difficulty concentrating

•          Forgetfulness

•          Racing or intrusive thoughts

•          Enhanced decision-making ability

•          Indecisiveness

•          Improved long-term memory
Explanation: Chronic stress impairs the brain's ability to focus, often resulting in noticeable difficulty concentrating on tasks and increased forgetfulness in daily life. Individuals under sustained stress frequently experience racing or intrusive thoughts that make it difficult to relax or think clearly. This cognitive strain often leads to indecisiveness, as the mental resources normally available for weighing options become depleted.

31. Which of the following best explains why SEL competencies are increasingly integrated into workplace training programs?

•          They are required by federal law in all industries

•          They improve communication, collaboration, and employee wellbeing

•          They eliminate the need for technical skills training entirely

•          They are only relevant to entry-level employees
Explanation: Organizations increasingly integrate SEL competencies into workplace training because these skills measurably improve communication, collaboration, and overall employee wellbeing. Employees who can manage their emotions and navigate interpersonal dynamics effectively tend to contribute to a more positive and productive work environment. Rather than replacing technical training, SEL competencies complement it by strengthening the interpersonal foundation on which effective teamwork depends.

32. Recognizing that a new employee from a different country may have different expectations around workplace hierarchy is an example of which SEL competency?

•          Self-management

•          Social-awareness

•          Executive function

•          Self-awareness
Explanation: Social-awareness involves understanding that cultural background can shape a person's expectations and behavior in professional settings, including attitudes toward hierarchy and authority. Recognizing this without judgment allows for more effective onboarding and communication with employees from diverse backgrounds. This competency supports a more inclusive workplace where cultural differences are understood rather than misinterpreted as a lack of engagement or initiative.

33. Which of the following is the clearest example of self-assessment in a fitness context?

•          Tracking your own workout progress and adjusting your training plan accordingly

•          Comparing your gym performance to a stranger's social media posts

•          Ignoring signs of physical fatigue during training

•          Following a workout plan without any personal reflection
Explanation: Tracking personal workout progress and making adjustments based on that data requires honest reflection on one's own performance and physical responses. This process exemplifies self-assessment because it centers on individual growth and informed decision-making rather than external comparison. Individuals who regularly self-assess in this way are better able to set realistic goals and avoid injury from overtraining.

34. Noticing a pattern of becoming impatient during long meetings and reflecting on what triggers that reaction is an example of which SEL competency?

•          Self-awareness

•          Executive function

•          Communication and leadership

•          Social-awareness
Explanation: Self-awareness involves identifying recurring emotional patterns and reflecting on their underlying causes, such as recognizing impatience during long meetings. This kind of reflective insight allows individuals to better understand their own emotional triggers before those emotions influence their behavior. Building this awareness is a critical first step toward developing more effective self-regulation strategies.

35. Creating a detailed onboarding checklist to ensure no steps are missed when training new hires is an example of which SEL competency?

•          Communication and leadership

•          Self-awareness

•          Executive function

•          Social-awareness
Explanation: Executive function encompasses the organizational and planning skills needed to create systematic processes, such as a detailed onboarding checklist. This kind of structured planning ensures consistency and reduces the likelihood of important steps being overlooked. Developing and following such systems reflects strong self-directed organization applied to a practical, recurring task.

36. Using positive self-talk to stay calm during a high-pressure client presentation is an example of which SEL competency?

•          Self-management

•          Social-awareness

•          Executive function

•          Communication and leadership
Explanation: Self-management involves actively regulating one's internal state, including using strategies like positive self-talk to maintain composure under pressure. This technique helps counteract the physiological stress response that can otherwise impair performance during high-stakes situations. Consistently applying this kind of emotional regulation strategy supports more confident and effective communication in challenging moments.

37. Bringing together representatives from two conflicting departments to co-create a shared solution is an example of which SEL competency?

•          Self-awareness

•          Communication and leadership

•          Executive function

•          Social-awareness
Explanation: Communication and leadership involve facilitating collaboration between parties with differing perspectives to reach a mutually acceptable solution. Bringing together representatives from conflicting departments requires strong negotiation and mediation skills aimed at building consensus rather than imposing a single viewpoint. This kind of collaborative leadership helps resolve organizational conflict while maintaining positive working relationships across teams.

38. Offering meeting materials in multiple formats to accommodate colleagues with different learning preferences is an example of which SEL competency?

•          Self-management

•          Communication and leadership

•          Executive function

•          Self-awareness
Explanation: Communication and leadership involve tailoring information delivery to meet the diverse needs and preferences of an audience. Offering materials in multiple formats, such as written summaries alongside visual presentations, reflects an intentional effort to make information accessible to everyone. This adaptability improves overall comprehension and engagement across a varied team.

39. Reaching out to a mentor for guidance after struggling to meet a challenging sales target is an example of which SEL competency?

•          Executive function

•          Self-management

•          Social-awareness

•          Communication and leadership
Explanation: Self-management includes the resilience to seek constructive support after a setback rather than becoming discouraged or withdrawing. Proactively reaching out to a mentor for guidance demonstrates a willingness to take responsibility for improvement and to learn from more experienced colleagues. This kind of adaptive response helps transform a professional challenge into an opportunity for meaningful growth.

40. Independently completing an online certification to strengthen a skill gap identified during a performance review is an example of which SEL competency?

•          Social-awareness

•          Self-awareness

•          Executive function

•          Communication and leadership
Explanation: Executive function involves the self-directed planning necessary to identify a skill gap and take concrete steps to address it independently. Completing a certification without being explicitly directed to do so demonstrates strong initiative and long-term goal orientation. This proactive approach to self-directed learning reflects a key aspect of effective personal and professional development.

41. Coordinating quiet workspaces for team members who need to accommodate childcare during a hybrid workday is an example of which SEL competency?

•          Executive function

•          Communication and leadership

•          Self-management

•          Self-awareness
Explanation: Communication and leadership involve considering the practical, real-world circumstances of team members when organizing work arrangements. Coordinating accommodations for colleagues balancing childcare responsibilities reflects an inclusive leadership approach that supports work-life balance. This kind of thoughtful accommodation helps build trust and demonstrates genuine care for employees' individual circumstances.

42. Adjusting a client meeting time to accommodate a business partner observing a religious fasting period is an example of which SEL competency?

•          Social-awareness

•          Executive function

•          Self-management

•          Self-awareness
Explanation: Social-awareness involves recognizing and respecting the religious practices of business partners or colleagues, even when it requires adjusting standard scheduling. Accommodating a fasting period demonstrates cultural sensitivity and strengthens professional relationships built on mutual respect. This kind of awareness is increasingly important in globally connected workplaces where colleagues and partners come from diverse religious and cultural backgrounds.
