Nursing Elites

1. What is the major diet-derived antioxidant found in cell membranes?

• A. B12
• B. beta-carotene
• C. vitamin E
• D. vitamin A

Correct answer: C

Rationale: The correct answer is vitamin E. Vitamin E is the major antioxidant found in cell membranes, where it plays a crucial role in protecting them from oxidative damage. Although B12, beta-carotene, and vitamin A are important nutrients with specific functions in the body, they are not the primary antioxidants found in cell membranes. Vitamin E specifically localizes in cell membranes to neutralize free radicals and prevent lipid peroxidation, making it an essential antioxidant for cellular health.

2. 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.

3. A client with cirrhosis and ascites is being cared for by a nurse. Which of the following interventions should the nurse include in the plan of care?

• A. Decrease the client's fluid intake.
• B. Increase the client's saturated fat intake.
• C. Increase the client's sodium intake.
• D. Decrease the client's carbohydrate intake.

Correct answer: D

Rationale: In a client with cirrhosis and ascites, decreasing carbohydrate intake is essential as it helps reduce the production of ascitic fluid. Excess carbohydrates can lead to fluid retention. Choices A, B, and C are incorrect. Decreasing fluid intake can worsen dehydration, increasing saturated fat intake is not recommended due to its impact on liver health, and increasing sodium intake can worsen fluid retention and exacerbate ascites in these clients.

4. What outcome has been shown to be a benefit of breastfeeding that directly impacts the mother?

• A. conserving calcium stores
• B. contracting the uterus
• C. protecting against future hypertension
• D. speeding the resumption of ovulation

Correct answer: B

Rationale: The correct answer is B, contracting the uterus. Breastfeeding helps contract the uterus after childbirth, reducing postpartum bleeding and helping the uterus return to its pre-pregnancy size more quickly. Choices A, C, and D are incorrect because conserving calcium stores, protecting against future hypertension, and speeding the resumption of ovulation are not direct benefits of breastfeeding to the mother.

5. A nurse is providing teaching to the parent of an infant about introducing solid foods. The nurse should recommend that which of the following foods be introduced first?

• A. Strained fruits
• B. Pureed meats
• C. Cooked egg whites
• D. Iron-fortified cereal

Correct answer: D

Rationale: When introducing solid foods to infants, it is recommended to start with iron-fortified cereal as it is easily digestible and a good source of iron, an important nutrient for infants around 6 months of age. Strained fruits are usually introduced later due to their natural sugars. Pureed meats can be introduced after iron-fortified cereals to provide additional protein and iron. Cooked egg whites should be avoided until the infant is at least one year old to reduce the risk of allergies.
