1. Each of the following is a function of vitamin A, except one. Which is the exception?

Correct answer: C

Rationale: The correct answer is C. Maintenance of more than 200 genes is not a function of vitamin A; instead, it is a function of Vitamin D. Vitamin A plays a crucial role in the prevention of night blindness by aiding in the production of the visual pigment rhodopsin. It also supports the growth of soft tissues and bone, as well as the integrity of body openings and their linings. Choice C is incorrect because the maintenance of genes is primarily associated with Vitamin D, not Vitamin A.

2. A nurse is caring for an 8-month-old infant who screams when the parent leaves the room. The parent begins to cry and says, 'I don't understand why my child is so upset. I've never seen my child act this way around others before.' Which of the following statements should the nurse make?

Correct answer: A

Rationale: The correct answer is 'This is a normal, expected reaction for a child of this age.' Separation anxiety typically peaks around 8-10 months of age, leading to distress when separated from caregivers. Choice B is incorrect because the infant's behavior is more likely due to separation anxiety rather than overstimulation. Choice C is incorrect as the infant's behavior is not related to overexposure to caregivers but rather a natural developmental stage. Choice D is incorrect as the infant's behavior is not indicative of illness but rather a normal emotional response.

3. What type of drug would most likely be given to a patient following a myocardial infarction?

Correct answer: B

Rationale: Anticoagulants are the most suitable choice for a patient following a myocardial infarction. These medications are essential in preventing further blood clots from forming in the arteries, reducing the risk of complications such as strokes or recurrent heart attacks. Antiemetics are used to control nausea and vomiting, not directly related to myocardial infarction. Anticonvulsants are used to manage seizures, not typically indicated after a heart attack. Antibiotics are prescribed to treat bacterial infections, not routinely given after a myocardial infarction.

4. Amy is a 68-year-old patient who has rheumatoid arthritis affecting her hands and feet. Which substance has been shown to reduce joint tenderness and improve mobility in some people with this type of arthritis?

Correct answer: D

Rationale: Fish oil has been identified as a substance that can help reduce joint tenderness and improve mobility in individuals with rheumatoid arthritis, as it is rich in omega-3 fatty acids. Omega-3 fatty acids have anti-inflammatory properties that can help alleviate the symptoms of rheumatoid arthritis. On the other hand, while Alfalfa Tea, Cod Liver Oil, and Lecithin have various health benefits, there isn't substantial evidence to suggest that they can improve conditions associated with rheumatoid arthritis.

5. If a person could not make bile, what would happen?

Correct answer: D

Rationale: The correct answer is D. Bile is essential for emulsifying fats in the small intestine, allowing them to be absorbed. Without bile, most fats would not be absorbed and would be excreted in the feces. Choices A, B, and C are incorrect because the primary role of bile is in the digestion and absorption of fats, rather than affecting lipid carriers, cholesterol production, or dietary fat consumption.
