1. How is the stomach protected from damage by gastric acid?
- A. enzymes present in the stomach
- B. a protective bacteria in the stomach
- C. bicarbonate present in the stomach
- D. the mucus lining of the stomach
Correct answer: D
Rationale: The correct answer is D. The stomach is protected from gastric acid by a thick mucus lining that acts as a physical barrier, preventing the acid from eroding the stomach walls. Enzymes in the stomach help with digestion but do not play a significant role in protecting the stomach from acid damage, so choice A is incorrect. While some bacteria in the stomach can be beneficial, they do not primarily protect the stomach from gastric acid, making choice B incorrect. Bicarbonate, a base, can neutralize acid, but it is not the primary defense mechanism against gastric acid in the stomach, so choice C is also incorrect.
2. A nurse is instructing a group of clients about nutrition. The nurse should include that which of the following is a trigger for the formation of vitamin D in the body?
- A. Calcium
- B. Vitamin A depletion
- C. Exposure to sunlight
- D. Weight-bearing exercise
Correct answer: Exposure to sunlight
Rationale: Exposure to sunlight is the trigger for the formation of vitamin D in the body. When the skin is exposed to sunlight, it produces vitamin D. This process is essential for maintaining healthy levels of vitamin D in the body. Calcium (Choice A) is important for bone health but is not the trigger for vitamin D formation. Vitamin A depletion (Choice B) does not directly trigger the formation of vitamin D. Weight-bearing exercise (Choice D) is crucial for bone health but is not directly related to the formation of vitamin D.
3. The most energy-rich nutrient is:
- A. carb
- B. fat
- C. protein
- D. water
Correct answer: B
Rationale: Fat provides 9 kcal per gram, making it the most energy-rich nutrient compared to carbohydrates and proteins, which provide 4 kcal per gram.
4. When conducting assessments for malnutrition, which risk factors should the nurse consider? (SATA)
- A. Dental problems
- B. Depression
- C. Ability to read and write
- D. All of the above
Correct answer: D
Rationale: When assessing for malnutrition, nurses should consider multiple risk factors. Dental problems and depression can impact a person's ability to eat and maintain proper nutrition. The ability to read and write may not directly relate to malnutrition risk. The correct answer is 'All of the above' because dental problems and depression are indeed risk factors, along with other factors like the inability to prepare meals and the loss of a spouse.
5. If there is an accidental injury to the parathyroid gland during a thyroidectomy which of the following might Leda develop postoperatively?
- A. Cardiac arrest C. Respiratory failure
- B. Dyspnea D. Tetany
- C.

Correct answer: C
Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.
