1. Which cells in the islet of the pancreas are responsible for synthesizing insulin?

Correct answer: B

Rationale: Beta cells in the islets of Langerhans in the pancreas are responsible for the production and secretion of insulin, which is crucial for regulating blood glucose levels. Alpha cells, on the other hand, produce glucagon, a hormone that raises blood glucose levels. Gamma cells and Delta cells do not exist in the islets of Langerhans; therefore, they are incorrect choices.

2. 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.

3. During the acute phase of a burn, the priority nursing intervention in caring for this client is:

Correct answer: D

Rationale: During the acute phase of a burn, fluid resuscitation is the priority nursing intervention. This phase is characterized by fluid loss and the risk of hypovolemic shock. Administering fluids is crucial to maintain perfusion and prevent complications such as organ failure. While prevention of infection, pain management, and prevention of bleeding are important aspects of burn care, fluid resuscitation takes precedence in the acute phase to stabilize the client's condition and prevent further damage.

4. The nurse is caring for a client taking warfarin. Which meal brought in by the client's family is a priority to remove before the client eats it?

Correct answer: C

Rationale: The correct answer is C. Ham is high in vitamin K, which can interfere with warfarin. Vitamin K can decrease the effectiveness of warfarin, an anticoagulant medication. Choices A, B, and D do not contain high levels of vitamin K and are less likely to interfere with the client's warfarin therapy.

5. 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?

Correct answer: C

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.
