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

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

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. The nurse is planning education about appropriate protein food choices for a client who has recently been prescribed a renal diet. Which protein food items should the nurse include in the education?

• A. Yogurt, seeds, and lentils
• B. Beef, bacon, and nuts
• C. Peanut butter, beans, and peas
• D. Poultry, eggs, and fish

Correct answer: D

Rationale: The correct answer is D: Poultry, eggs, and fish. These protein sources are high-quality proteins suitable for a renal diet as they provide essential amino acids without excessive amounts of potassium or phosphorus. Choice A, yogurt, seeds, and lentils, may be high in potassium and phosphorus, which could be restricted in a renal diet. Choice B, beef, bacon, and nuts, are also high in phosphorus and may not be ideal for a renal diet. Choice C, peanut butter, beans, and peas, are high in potassium and phosphorus, making them less suitable for a renal diet.

3. The stages of grieving identified by Elizabeth Kubler-Ross are:

• A. Numbness, anger, resolution and reorganization
• B. Denial, anger, identification, depression and acceptance
• C. Anger, loneliness, depression and resolution
• D. Denial, anger, bargaining, depression and acceptance

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.

4. Diseases of the heart and blood vessels are collectively referred to as _____.

• A. Coronary artery disease
• B. Cardiovascular disease
• C. Coronary heart disease
• D. Coronary vessel disease

Correct answer: B

Rationale: The correct term for diseases of the heart and blood vessels is cardiovascular disease. While coronary artery disease (Choice A) specifically involves the narrowing of coronary arteries, it is just one type of cardiovascular disease. Coronary heart disease (Choice C) is also a specific condition related to the heart's blood vessels. Choice D, coronary vessel disease, is not a commonly used term to describe diseases of the heart and blood vessels. Therefore, Choice B, cardiovascular disease, is the most inclusive and appropriate term to refer to these conditions.

5. A client who 1) _____ diet requires 2) ___ amounts of vitamin C.

• A. A) Follows a vegan diet, B) More
• B. B) Smokes cigarettes, B) More
• C. A) Follows a vegan diet, C) The same
• D. B) Smokes cigarettes, C) The same

Correct answer: B

Rationale: The correct answer is B) Smokes cigarettes, More. Smoking increases the need for vitamin C as it can deplete the body's vitamin C levels. Vegan diets, on the other hand, require more vitamin C for optimal absorption due to the absence of heme iron, which enhances non-heme iron absorption. Choices A and C are incorrect because vegan diets require more vitamin C, while smoking increases the need for vitamin C.
