1. Milk and other dairy products are preferred sources of calcium because lactose enhances calcium absorption.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: A

Rationale: Both the statement and the reason are correct and related. Milk and other dairy products are indeed preferred sources of calcium because they supply most of the available calcium. Additionally, lactose present in dairy products enhances calcium absorption, making them even more efficient sources of this essential mineral. The statement correctly identifies dairy products as preferred sources of calcium, and the reason explains how lactose contributes to better calcium absorption. The other choices are incorrect as they do not accurately assess the relationship between lactose, calcium absorption, and the preference for dairy products as sources of calcium.

2. What is a major constituent of cell membranes?

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: B

Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.

3. Which foods are the biggest contributors of saturated fats consumed by Americans?

• A. Butter, coconut, and palm oils
• B. Corn oil
• C. Meat and milk
• D. Cheese, pizza, desserts, and chicken

Correct answer: D

Rationale: The correct answer is D: Cheese, pizza, desserts, and chicken. These foods are significant contributors to the intake of saturated fats in the American diet, often found in processed and fast foods. Choices A, B, and C are incorrect because while butter, coconut, and palm oils (A) are sources of saturated fats, they are not the biggest contributors in the American diet. Corn oil (B) is a source of unsaturated fats, and meat and milk (C) contain saturated fats but are not the primary contributors compared to cheese, pizza, desserts, and chicken.

4. In monitoring the patient in PACU, the nurse correctly identifies that checking the patient's vital signs is done every:

• A. 1 hour
• B. 5 minutes
• C. 15 minutes
• D. 30 minutes

Correct answer: A

Rationale: Correct Answer: A - Vital signs monitoring in the PACU (Post-Anesthesia Care Unit) is typically done every hour to closely monitor the patient's condition during the immediate postoperative period. This frequency allows the nurse to promptly identify any changes in the patient's vital signs and intervene as necessary. Choice B (5 minutes) is too frequent for routine vital signs monitoring in the PACU and may not allow for a comprehensive assessment of the patient's stability. Choice C (15 minutes) and Choice D (30 minutes) are also not in line with the standard practice of vital signs monitoring in the PACU, which is typically hourly.

5. Loss of smell results in a condition that limits capacity to detect the flavor of food and beverages called:

• A. Hypergeusia
• B. Dysgeusia
• C. Anosmia
• D. Phantom taste

Correct answer: C

Rationale: Anosmia is the loss of the sense of smell, which significantly impacts the ability to detect flavors in food and beverages.
