1. What physiologic role does magnesium play in the body?

Correct answer: B

Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.

2. During blood administration, what is essential for the nurse to do in order to carefully monitor for adverse reactions?

Correct answer: A

Rationale: In the context of blood administration, it's crucial for the nurse to stay with the client for the first 15 minutes. This is because most adverse reactions are likely to occur within this initial period. Monitoring the client closely during this time allows for immediate detection and response to any potential reactions. Choice B, staying with the client for the entire period of blood administration, is not typically feasible or necessary, although regular checks should be conducted. Running the infusion at a faster rate during the first 15 minutes (Choice C) is incorrect as this can actually increase the risk of adverse reactions. Informing the client to notify the staff immediately for any adverse reaction (Choice D) is an important practice, but it is not the most direct way for the nurse to monitor for adverse reactions.

3. Proteolytic enzymes are most likely to break down which food type?

Correct answer: B

Rationale: Proteolytic enzymes target proteins for breakdown into amino acids. Carbohydrates are broken down by enzymes like amylase, while fats are broken down by lipase. Lipids, which include fats, are not specifically targeted by proteolytic enzymes.

4. Maria’s statement “Bow down before me! I am the holy mother of Christ! I am the blessed Virgin Mary!” is an example of:

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. After ileostomy, which of the following condition is NOT expected?

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
