Nursing Elites

1. Each statement is true, except one. Which is the exception?

• A. Infant formulas should be discontinued at approximately 1 year of age
• B. Low-fat milk is not recommended for children younger than 2 years
• C. Special toddler formulas are available but are unnecessary
• D. Vitamin D-fortified whole milk should not be provided until 2 years

Correct answer: D

Rationale: The correct answer is D. Vitamin D-fortified whole milk should be provided starting at age 1 after discontinuing breast feeding or infant formulas, not at 2 years. Providing whole milk at age 2 is appropriate. Choices A, B, and C are correct statements: infant formulas are typically discontinued around 1 year of age, low-fat milk is not recommended for children under 2 years, and special toddler formulas are unnecessary.

2. Which lipid contains 3 fatty acids?

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

Correct answer: D

Rationale: The correct answer is 'D. triglyceride.' Triglycerides are composed of one glycerol molecule and three fatty acids, making them the primary form of stored fat in the body. Cholesterol (A) is a different type of lipid, phospholipids (B) have two fatty acids, and 'saturated' (C) refers to the structure of fatty acids, not a specific lipid containing 3 fatty acids.

3. Each of the following accurately describes aspects of the dietary reference intakes (DRIs) published by the Food and Nutrition Board of the Institute of Medicine (IOM) except one. Which one is the exception?

• A. The DRIs replace the older recommended daily allowances
• B. Current DRIs attempt to estimate required nutrients to improve long-term health
• C. DRIs specifically address individuals whose requirements are affected by a disease state
• D. The DRIs attempt to establish maximum safe levels of tolerance for nutrients

Correct answer: C

Rationale: The correct answer is C. DRIs are intended for the general population and do not specifically address disease states, which are managed with different clinical guidelines. Choice A is correct as DRIs have replaced the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate the required nutrients for long-term health. Choice D is correct as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.

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. Intrinsic factor from the stomach is needed for the absorption of which vitamin?

• A. vitamin B12
• B. folate
• C. niacin
• D. vitamin B6

Correct answer: A

Rationale: The correct answer is A: vitamin B12. Intrinsic factor is a glycoprotein produced by the stomach that is necessary for the absorption of vitamin B12 in the small intestine. Vitamin B12 binds to intrinsic factor in the stomach, forming a complex that is then absorbed in the ileum. This absorption process is crucial for preventing vitamin B12 deficiency. Choices B, C, and D are incorrect because they do not require intrinsic factor for absorption. Folate is absorbed in the small intestine through a different mechanism, niacin can be absorbed in the small intestine without the need for intrinsic factor, and vitamin B6 does not rely on intrinsic factor for absorption.
