How many of these 20 do I need to get right to be on track?

About 16. A passing score works out to roughly 80 percent, so clearing 16 of 20 consistently across a few sets puts you in passing range.

Are these the same questions that appear on the real exam?

No. These are representative practice questions in the exam's style. The real exam draws from a much larger pool, which is why practice volume, not memorizing any single set, is what moves your score.

20 DSST Health and Human Development practice questions, with answers and video walkthroughs

Twenty practice questions for DSST Health and Human Development, in the real exam's style. Score 16 of 20 here and you are in passing range. Miss more than four, and the pattern of your misses points straight at the topic to review next. Every question below is explained on video, including why the wrong answers trap most test-takers.

What students preparing for this exam tell us is that steady practice in the exam's format, with an explanation for every miss, is what moves a score. Use these the same way: answer, check, and read why the wrong choices are tempting. For the full plan around them, see the DSST Health and Human Development pillar guide.

Watch the full video walkthrough above, then test yourself on the twenty questions below. Each one is explained on the video, including why the wrong answers trap most test-takers.

Questions 1 to 5 (questions 1 to 5)

1. According to Jean Piaget, an infant who understands that an object still exists after it is hidden from view has developed: Object Permanence. Object permanence is the understanding that things continue to exist even when out of sight. Piaget placed it in the sensorimotor stage, the first stage of cognitive development in infancy.

2. The principle that physical growth and motor control proceed from the head downward toward the feet is called: The Cephalocaudal Trend. The cephalocaudal trend describes development that moves from the head down. This is why babies gain control of their head and neck before they can sit, and sit before they can walk.

3. According to Erik Erikson, the central psychosocial conflict of adolescence is: Identity Versus Role Confusion. Erikson framed adolescence as identity versus role confusion. The teenager's main task is forming a stable sense of self, asking who they are and where they fit in the world.

4. In Piaget's theory, the ability to understand that pouring water into a taller glass does not change the amount of water is known as: Conservation. Conservation is knowing that quantity stays the same despite a change in shape or container. Piaget tied it to the concrete operational stage, roughly ages seven to eleven.

5. Which of the following is most strongly associated with normal physical changes during late adulthood? Decreased Visual Acuity and Hearing. Aging typically brings gradual sensory decline, including reduced sharpness of vision and hearing. Metabolism, reaction time, and bone density generally decrease rather than rise with age.

Questions 6 to 10 (questions 6 to 10)

6. Which nutrient class is the body's primary and most efficient source of energy? Carbohydrates. Carbohydrates are the body's preferred fuel, broken down into glucose for quick energy. Proteins build and repair tissue, while vitamins and minerals support body processes but supply almost no energy.

7. A vitamin that dissolves in fat and can be stored in the body, making excess intake potentially toxic, is best represented by: Vitamin a. Vitamins A, D, E, and K are fat-soluble and stored in body fat and the liver, so large doses can build up to harmful levels. Vitamin C and the B vitamins are water-soluble and flushed out more easily.

8. The component of physical fitness that refers to the heart, lungs, and blood vessels supplying oxygen during sustained activity is called: Cardiorespiratory Endurance. Cardiorespiratory endurance is the ability of the heart and lungs to deliver oxygen during prolonged exercise. Activities like jogging, swimming, and cycling build it most directly.

9. Body mass index, or BMI, is calculated using a person's: Weight and Height. BMI is a ratio of weight to height used to screen for underweight, healthy weight, and overweight categories. It does not directly measure body fat, so it is a screening tool, not a diagnosis.

10. Which of the following is the most accurate description of a Calorie as used in nutrition? A Unit of Energy. A Calorie is a unit that measures the energy food provides to the body. Foods high in fat carry more calories per gram than foods high in carbohydrate or protein.

Questions 11 to 15 (questions 11 to 15)

11. Hans Selye's general adaptation syndrome describes the body's response to stress in three stages, in this order: Alarm, Resistance, Exhaustion. Selye's general adaptation syndrome runs from alarm, the initial fight-or-flight reaction, to resistance, where the body copes, to exhaustion, when prolonged stress depletes the body's reserves.

12. In Maslow's hierarchy of needs, reaching one's full potential and becoming everything one is capable of becoming describes: Self-actualization. Self-actualization sits at the top of Maslow's pyramid. It is the drive to fulfill one's potential and is reached only after more basic needs, like food, safety, and belonging, are met.

13. The fight-or-flight response, the body's rapid reaction to a perceived threat, is triggered mainly by: The Sympathetic Nervous System. The sympathetic nervous system drives fight-or-flight, releasing adrenaline to raise heart rate and breathing. The parasympathetic system later calms the body back down once the threat passes.

14. A defense mechanism in which a person attributes their own unacceptable feelings to someone else is called: Projection. Projection means pushing one's own unwanted thoughts or feelings onto another person, such as an angry person insisting that everyone else is angry. It is one of the ego defenses Freud described.

15. The leading category of preventable death in the United States is most closely linked to: Tobacco Use. Tobacco use is the single largest cause of preventable death in the United States, driving heart disease, lung cancer, and stroke. This is why smoking cessation is a top public health priority.

Questions 16 to 20 (questions 16 to 20)

16. Fertilization, the union of a sperm and an egg, normally occurs in the: Fallopian Tube. Fertilization usually happens in the fallopian tube, where sperm meet the released egg. The resulting zygote then travels to the uterus, where it implants in the lining and develops.

17. Which of the following is a viral sexually transmitted infection that cannot be cured with antibiotics? Hiv. HIV is caused by a virus, so antibiotics do not cure it; it is managed with antiviral medication. Chlamydia, gonorrhea, and syphilis are bacterial and can be cured with the right antibiotics.

18. The human trait of having brown eyes, which masks a recessive blue-eye allele, is an example of a trait that is: Dominant. A dominant trait shows up even when only one copy of its allele is present, masking the recessive version. Brown eye color is commonly dominant over blue, which is why it appears more often.

19. Which screening practice is recommended specifically for the early detection of breast cancer? A Mammogram. A mammogram is an X-ray of the breast used to find tumors early, often before they can be felt. Early detection through regular mammograms significantly improves breast cancer survival rates.

20. The first 24 hours of life, the trimester structure of pregnancy, and the period of most rapid brain growth all fall within which broad field of study? Human Development. Human development is the study of how people grow and change across the lifespan, from conception through old age. Prenatal stages, infancy, and brain growth are core topics within it.

What to do with your score

The point of twenty questions is not the twenty, it is the pattern. Mark which topic each miss came from, then spend your next session on that topic alone. None of it requires starting over, only tightening the spots that cost you points.

A single twenty-question set is a snapshot, not a study plan. To pass with margin you need volume: enough questions, in the exam's format, with explanations that turn a wrong answer into a correction. That is what Flying Prep's DSST Health and Human Development practice is built for: every question explained, with a free trial before you decide.
