Nursing Elites

1. When is infertility said to exist?

• A. When a woman has no uterus
• B. When a woman has no children
• C. When a couple has been trying to conceive for 1 year without success
• D. When a couple has desired a child for 6 months

Correct answer: C

Rationale: Infertility is defined as not being able to get pregnant despite having frequent, unprotected sex for at least a year for most couples. Therefore, the correct answer is C. A, B, and D are incorrect. While having no uterus (choice A) may result in infertility, it is not the sole determining factor. Similarly, not having children (choice B) does not automatically indicate infertility. Lastly, the time frame of 6 months (choice D) is not sufficient to determine infertility; typically, a year of trying without success is required for such a diagnosis.

2. Which enzyme digests fiber in the large intestine?

• A. salivary amylase
• B. pancreatic amylase
• C. cellulase
• D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.

3. Plant stanols and sterols help to lower LDL cholesterol and are often added to which food product?

• A. margarine
• B. milk
• C. cereal
• D. yogurt

Correct answer: A

Rationale: Plant stanols and sterols are commonly added to margarine to help lower LDL cholesterol levels. Margarine acts as a vehicle for these compounds, making it easier for individuals to incorporate them into their daily diet. While milk, cereal, and yogurt are healthy food options, they are not typically enriched with plant stanols and sterols for cholesterol-lowering purposes, making them less likely candidates as the correct answer.

4. A client is being taught by a nurse about adding more fiber to the diet. Which of the following foods has the highest fiber content?

• A. 1 cup cooked sweet potato
• B. 1 slice rye toast
• C. 1 cup raw watermelon
• D. 1 oz cashews

Correct answer: D

Rationale: The correct answer is D, 1 oz of cashews. Cashews have a higher fiber content compared to sweet potato, rye toast, and watermelon. While sweet potatoes and rye toast contain fiber, cashews have a higher concentration, making them a better choice for increasing fiber intake. Watermelon, on the other hand, is low in fiber compared to the other options provided.

5. 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.
