Question 1: Which nutrient is most critical for wound healing after a workplace injury?
- Protein (Correct answer)
- Carbohydrates
- Saturated fat

Correct answer: Protein
Protein provides the amino acids needed to rebuild damaged tissue and support immune function during wound healing.
Question 2: A worker frequently skips breakfast before a long shift. What is the most likely nutritional consequence?
- Improved concentration
- Reduced blood glucose leading to fatigue (Correct answer)
- Increased muscle mass
- Decreased caloric need
Correct answer: Reduced blood glucose leading to fatigue
Skipping breakfast can cause blood glucose to drop, impairing alertness, concentration, and physical performance during a shift.
Question 3: According to NSC guidelines, which eating pattern best supports sustained energy for shift workers?
- One large meal at the end of the shift
- Frequent small meals and snacks throughout the shift (Correct answer)
- High-sugar snacks every hour
- Fasting until the shift is complete
Correct answer: Frequent small meals and snacks throughout the shift
Frequent small meals help maintain stable blood glucose levels, preventing energy crashes during extended work periods.
Question 4: What is the primary role of iron in occupational health nutrition?
- Regulating blood pressure
- Supporting oxygen transport in the blood (Correct answer)
- Building bone density
- Metabolizing alcohol
Correct answer: Supporting oxygen transport in the blood
Iron is a core component of hemoglobin, which carries oxygen from the lungs to working muscles and organs.
Question 5: A warehouse worker in a hot environment loses significant sweat. Beyond water, which electrolyte is most urgently needed?
- Calcium
- Potassium
- Sodium (Correct answer)
- Magnesium
Correct answer: Sodium
Sodium is the primary electrolyte lost in sweat and must be replaced to maintain fluid balance and prevent hyponatremia.
Question 6: Which vitamin deficiency is most associated with impaired night vision, which can be a safety hazard in low-light work environments?
- Vitamin C
- Vitamin D
- Vitamin A (Correct answer)
- Vitamin K
Correct answer: Vitamin A
Vitamin A is essential for producing rhodopsin, the pigment in the eyes that enables vision in low-light conditions.
Question 7: When counseling workers about reducing cardiovascular risk through diet, which type of fat should be most limited?
- Monounsaturated fat
