1. Which systolic blood pressure measurement is classified as prehypertension?

• A. 106 mmHg
• B. 119 mmHg
• C. 130 mmHg
• D. 141 mmHg

Correct answer: B

Rationale: According to the blood pressure classification, a systolic blood pressure between 120-139 mmHg is considered prehypertension. This range indicates an increased risk for developing hypertension if not managed appropriately. Therefore, a systolic blood pressure of 119 mmHg falls into the prehypertension category. A systolic pressure of 106 mmHg is within the normal range, while 130 mmHg and above would be classified as stage 1 and stage 2 hypertension respectively, not prehypertension.

2. Nutrition therapy for clients with diabetes is based on:

• A. low dietary intake of sugars
• B. standardized diabetic diet plans
• C. each client’s lifestyle and preferences
• D. the client’s weight and blood glucose level

Correct answer: C

Rationale: Corrected Rationale: Nutrition therapy for clients with diabetes should be individualized to each client's lifestyle, preferences, and needs. This approach ensures that the dietary plan is sustainable and tailored to the client, leading to better adherence and improved health outcomes. Choices A and B are too general and do not account for individual differences among clients. Choice D, focusing solely on weight and blood glucose levels, overlooks other crucial aspects of a client's overall well-being and dietary requirements in diabetes management.

3. One of the following statements is true with regards to the care of clients with depression:

• A. Only mentally ill persons commit suicide
• B. All depressed clients are considered potentially suicidal
• C. Most suicidal person gives no warning
• D. The chance of suicide lessens as depression lessens

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.

4. Which vitamin acts most like a hormone?

• A. Vitamin A
• B. Vitamin B
• C. Vitamin D
• D. Vitamin C

Correct answer: C

Rationale: The correct answer is Vitamin D. Although vitamin D, also known as calciferol, has been called a vitamin, it is more appropriately classified as a hormone. Like hormones, vitamin D acts to control the function of other cell types. For example, it helps the body absorb and regulate skeletal calcium and phosphorus levels. Choice A (Vitamin A) plays a crucial role in vision and immune function. Choice B (Vitamin B) is a complex of different vitamins that play various roles in the body. Choice D (Vitamin C) is important for collagen production and acts as an antioxidant.

5. 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.
