30 multiple-choice questions and 10 flashcards on Health and Wellness Foundations, about 20% of the HS Health & Wellness bank. Every one carries a written rationale.
Health and Wellness Foundations is one of 12 chapters in CoStudy's HS Health & Wellness bank, and it holds 30 of the bank's 150 multiple-choice questions — roughly 20% of the total. That proportion is not arbitrary: chapters follow the certifying body's published exam outline, and the number of questions in each is set by that domain's published weight, so the share of your practice time this chapter takes matches the share of the real exam it accounts for.
Studying by chapter is worth doing once you have a diagnostic score. A single overall percentage tells you whether you are close; it does not tell you which domain is dragging. Working a weak chapter in isolation, and re-testing it in isolation, is the fastest way to move a score that has stalled — and it is why the mock exams in CoStudy report by domain rather than as one number.
10 questions drawn from this chapter, with the full rationale shown — the controlling principle behind the right answer, and why each wrong option tempts and fails.
Hydration: roughly how much fluid does the average teenager need daily (from food and drinks)?
Answer: B — Roughly 2–3 liters total daily, more with heat or exercise
General guidance suggests ~2–3 liters total fluid daily for teens/adults; needs rise with heat, exercise, illness. Most fluid can come from beverages plus water-rich foods.

Answer: C — 0.08%
0.08% is the standard adult per-se DUI limit in most U.S. states. Utah set 0.05% in 2018. Drivers under 21 face zero-tolerance limits (≈0.02%).
According to the USDA MyPlate guidelines, approximately what fraction of your plate should be fruits and vegetables?
Answer: B — About 50%
MyPlate recommends filling about half the plate with fruits and vegetables, with the other half split between grains and proteins, plus dairy on the side.
Three macronutrients are:
Answer: D — Carbohydrates (4 cal/g), proteins (4 cal/g), fats (9 cal/g) — provide energy and building blocks
Macronutrients: carbs (preferred energy, 4 cal/g), protein (build/repair tissue, 4 cal/g), fats (energy + cell membranes + hormones, 9 cal/g, most calorie-dense). Alcohol 7 cal/g but not nutrient. Micronutrients = vitamins, minerals.
Which of the following is a macronutrient?
Answer: C — Carbohydrates
Macronutrients (carbohydrates, proteins, fats) are needed in large quantities and provide energy. Vitamins and minerals are micronutrients.
Which is generally regarded as a warning sign of depression?
Answer: D — Persistent low mood, loss of interest, fatigue, and changes in sleep/appetite for two or more weeks
Major depressive disorder requires persistent symptoms (≥2 weeks) significantly affecting functioning. Brief sadness is part of normal life.
