Nursing Elites

1. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?

• A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
• B. Viscous fiber binds with bile in the intestine and is excreted in feces
• C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
• D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol

Correct answer: B

Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.

2. Select all that apply. Characteristics of the 2 main types of essential fatty acids discussed in class include:

• A. they must be supplied by the diet
• B. they can be produced by a process called dehydrogenation
• C. they are anti-inflammatory
• D. they are all polyunsaturated fatty acids

Correct answer: A

Rationale: The correct answer is A: 'they must be supplied by the diet.' Essential fatty acids, like omega-3 and omega-6, cannot be produced by the body and must be obtained through the diet. They are polyunsaturated fatty acids, playing vital roles in inflammation and cell membrane structure. Choice B is incorrect because essential fatty acids cannot be produced by dehydrogenation, a process of removing hydrogen. Choice C is incorrect as not all essential fatty acids are anti-inflammatory; some have pro-inflammatory roles. Choice D is incorrect because not all essential fatty acids are polyunsaturated; omega-9, for example, is a monounsaturated essential fatty acid.

3. Individuals who use antiretroviral drugs frequently develop insulin resistance and _____.

• A. hypertension
• B. hypothyroidism
• C. hyperlipidemia
• D. fluid retention

Correct answer: C

Rationale: The correct answer is C: hyperlipidemia. Antiretroviral drugs can often lead to elevated lipid levels (hyperlipidemia), which is a common side effect of this therapy. This increase in lipids can contribute to cardiovascular risk. Hypertension (choice A) is not typically associated with antiretroviral drug use. Hypothyroidism (choice B) and fluid retention (choice D) are also not commonly linked to antiretroviral therapy.

4. A nurse is teaching a parent about appropriate snack choices for her 9-month-old infant. Which of the following food choices should the nurse recommend?

• A. Skim milk
• B. Unsalted popcorn
• C. Graham crackers
• D. Raw carrots

Correct answer: C

Rationale: Graham crackers are an appropriate snack choice for a 9-month-old infant due to their texture and ease of consumption. Skim milk (Choice A) is not recommended for infants under 1 year old due to the potential risk of developing milk allergies. Unsalted popcorn (Choice B) can be a choking hazard for infants. Raw carrots (Choice D) are a potential choking hazard for a 9-month-old infant and may be difficult for them to chew and digest.

5. A nurse is caring for a client who is to receive a mechanically altered diet. Which of the following client food choices necessitates intervention by the nurse?

• A. Scrambled eggs
• B. Cottage cheese
• C. Piece of wheat toast
• D. Sliced banana

Correct answer: D

Rationale: The correct answer is 'Sliced banana.' A mechanically altered diet is designed for clients who have difficulty chewing or swallowing. Sliced bananas, due to their texture and potential choking hazard for clients with swallowing difficulties, would necessitate intervention by the nurse. Scrambled eggs, cottage cheese, and a piece of wheat toast are softer and safer options for clients on a mechanically altered diet, making them appropriate choices.
