Nursing Elites

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 do not specifically address individuals with disease states; they are intended for the general healthy population. Choice A is correct because DRIs indeed replace the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate required nutrients to enhance long-term health. Choice D is accurate as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.

2. How many grams of protein per day are recommended for a person weighing 150 lbs?

• A. 120
• B. 85
• C. 187.5
• D. 54

Correct answer: D

Rationale: The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight. To convert pounds to kilograms, divide the weight in pounds by 2.2. Therefore, a 150 lb person weighs approximately 68 kg (150 / 2.2 = 68). Multiplying 68 kg by 0.8 grams gives us 54 grams of protein per day. Choices A, B, and C are incorrect as they do not align with the RDA calculation based on body weight.

3. You will give health instructions to Carlo, a case of bronchial asthma. The health instruction will include the following, EXCEPT:

• A. Avoid emotional stress and extreme temperature
• B. Avoid pollution like smoking
• C. Avoid pollens, dust, seafood
• D. Practice respiratory isolation

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. What is the term for a condition where one or more members of a household, including children, consistently have little or no food due to lack of money?

• A. Marginal Food Security
• B. Food Desert
• C. Very Low Food Security
• D. Food Insecurity

Correct answer: D

Rationale: The correct answer is 'D: Food Insecurity'. This term specifically describes a situation where household members consistently have inadequate access to food due to financial constraints. 'Marginal Food Security' (Choice A) refers to a situation where the quality or variety of food is reduced, but there is no significant decrease in food intake. A 'Food Desert' (Choice B) is an area with limited access to affordable and nutritious food. 'Very Low Food Security' (Choice C) is a term used to describe a severe level of food insecurity where eating patterns of household members are disrupted and food intake is reduced.

5. What is the most common type of kidney stone?

• A. Cystine
• B. Calcium
• C. Struvite
• D. Uric acid

Correct answer: B

Rationale: The most common type of kidney stone is calcium-based, specifically calcium oxalate. This is usually due to high calcium levels in the urine, which can be caused by dietary factors or certain metabolic disorders. Cystine stones, on the other hand, are less common and occur in individuals with a hereditary disorder leading to excessive excretion of certain amino acids. Struvite stones are often formed in response to an infection. Uric acid stones may occur in individuals who do not consume sufficient fluids or who lose too much fluid, among other factors. Therefore, while all these substances can form stones in the kidneys, calcium stones are the most common.
