1. 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.

2. Muscle weakness due to wasting would most likely be evaluated by which test?

A. recall of food intake
B. skinfold thickness
C. handgrip strength
D. red blood cell levels

Correct answer: C

Rationale: Handgrip strength is a reliable test to assess muscle function and detect muscle weakness due to wasting. It is often used to identify conditions like sarcopenia in clinical settings. Options A, B, and D are not suitable for evaluating muscle weakness. Food intake recall does not directly measure muscle function, skinfold thickness assesses body fat but not muscle strength, and red blood cell levels are unrelated to muscle wasting.

3. What action should the nurse take first for a client with Listeria food poisoning?

A. Educate the client on safe food practices.
B. Start a traceback to identify the source of the outbreak.
C. Report the case to the county board of health.
D. Ask the client if they have consumed any unpasteurized products.

Correct answer: D

Rationale: Identifying the source of Listeria is crucial for preventing further cases.

4. Which enzyme initiates protein digestion in the stomach?

A. Pepsin
B. Salivary Amylase
C. CCK
D. Secretin

Correct answer: A

Rationale: Pepsin is the enzyme that initiates protein digestion in the stomach. It breaks down proteins into smaller peptides, aiding in their further digestion and absorption in the intestines. Salivary Amylase (Choice B) functions in breaking down dietary carbohydrates in the mouth, not proteins. CCK (Choice C) and Secretin (Choice D) are hormones involved in the digestion of fats and carbohydrates, not proteins. Therefore, Choices B, C, and D are incorrect in the context of protein digestion in the stomach.

5. What is the most important concern immediately after a myocardial infarction?

A. Reducing cholesterol intake
B. Allowing cardiac rest for healing
C. Reducing saturated fat intake
D. Eating several small meals each day

Correct answer: B

Rationale: Immediately after a myocardial infarction, the primary concern is to allow the heart to rest and heal to prevent further damage. This is why choice B is the correct answer. While choices A, C, and D might be a part of the long-term management plan following a myocardial infarction, they are not the immediate priority. Reducing cholesterol and saturated fat intake, as well as adjusting eating habits can help prevent future heart issues, but do not directly contribute to the immediate recovery post-myocardial infarction.
