1. Which systemic disease is best controlled with the DASH diet, monitoring blood pressure, limiting sodium, alcohol, and caffeine, reducing stress, and losing weight?

A. Hypertension
B. Diabetes mellitus
C. Parkinson's disease
D. Anemia

Correct answer: A

Rationale: The correct answer is A: Hypertension. The DASH diet is specifically designed to control hypertension by reducing sodium intake, managing blood pressure, and promoting overall cardiovascular health. Choice B, Diabetes mellitus, is managed through monitoring blood sugar levels and a balanced diet rich in whole grains, fruits, and vegetables. Choice C, Parkinson's disease, is a neurological disorder that is not primarily managed through diet modifications. Choice D, Anemia, is a condition characterized by a lack of healthy red blood cells and is typically managed by addressing the underlying cause and sometimes iron supplementation, not by the methods mentioned in the question.

2. 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.

3. What physiologic role does calcium 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: A

Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.

4. A nurse is caring for four clients. The nurse should plan to administer total parenteral nutrition for which of the following clients?

A. A client who is postoperative following a laminectomy and is receiving IV PCA
B. A client who has dysphagia and does not recognize his family
C. A client who has COPD and is going home with oxygen
D. A client who has colon cancer and will undergo a hemicolectomy

Correct answer: D

Rationale: Total parenteral nutrition (TPN) is essential for clients undergoing significant surgical procedures like a hemicolectomy to ensure they receive adequate nutrition when oral intake is not possible. Choices A, B, and C do not typically require TPN. Choice A is managing postoperative pain with IV PCA, choice B is likely to need alternative feeding methods due to dysphagia, and choice C is going home with oxygen for COPD management, which does not directly relate to the need for TPN.

5. What percentage of body weight as fat does a woman with a healthy body composition typically average?

A. 5%
B. 15%
C. 25%
D. 35%

Correct answer: C

Rationale: A healthy body fat percentage for women typically ranges between 21% and 33%, with 25% being an average healthy body fat percentage. Choice A (5%) is too low for a healthy body fat percentage and is more in line with essential body fat levels. Choice B (15%) is also lower than the typical range for a healthy body fat percentage. Choice D (35%) is too high and would be considered high body fat for women.
