Nursing Elites

1. Individuals with Klinefelter syndrome produce:

• A. less estrogen than normal males.
• B. less testosterone than normal males.
• C. less adenine than normal males.
• D. less thymine than normal males.

Correct answer: B

Rationale: Individuals with Klinefelter syndrome have an extra X chromosome (XXY), leading to reduced production of testosterone, the primary male sex hormone. This deficiency can result in various physical and developmental characteristics associated with the syndrome. Estrogen levels may actually be relatively elevated due to the imbalance between testosterone and estrogen. Choices C and D are incorrect as adenine and thymine are nucleotide bases found in DNA and are not related to hormone production.

2. _________ is self-propulsion.

• A. Mitosis
• B. Meiosis
• C. Motility
• D. Mutation

Correct answer: C

Rationale: The correct answer is 'Motility.' Motility refers to the ability of cells or organisms to move by themselves, often through the use of specialized structures like flagella or cilia. Mitosis (Choice A) and Meiosis (Choice B) are processes related to cell division and genetic recombination, respectively, not self-propulsion. Mutation (Choice D) refers to changes in the DNA sequence and is not related to self-propulsion.

3. A client who is 5 days postpartum is being taught about signs of effective breastfeeding. Which information should the nurse include in the teaching?

• A. Feeling a tugging sensation when the baby is sucking
• B. Expecting the baby to have two to three wet diapers in a 24-hour period
• C. The baby’s urine should appear dark and concentrated
• D. The breast should stay firm after the baby breastfeeds

Correct answer: A

Rationale: Feeling a tugging sensation while the baby is sucking indicates an effective latch and milk transfer during breastfeeding. This sensation means that the baby is effectively drawing milk from the breast. Choice B is incorrect because infants should ideally have six to eight wet diapers in a 24-hour period to show adequate hydration. Choice C is incorrect as a dark and concentrated urine may indicate dehydration, which is not a sign of effective breastfeeding. Choice D is incorrect as the breast should soften after the baby breastfeeds, indicating that the baby has effectively emptied the breast of milk.

4. What causes sickle-cell anemia?

• A. A chromosomal abnormality.
• B. A single segment found only on the Y chromosome.
• C. A recessive gene.
• D. A decrease in estrogen levels.

Correct answer: C

Rationale: Sickle-cell anemia is a genetic disorder caused by inheriting two copies of a recessive gene, one from each parent. The correct answer is C. Choice A is incorrect because sickle-cell anemia is not primarily caused by a chromosomal abnormality. Choice B is incorrect as the condition is not linked to a single segment found only on the Y chromosome. Choice D is unrelated as it mentions a decrease in estrogen levels, which is not a cause of sickle-cell anemia.

5. The mother of a breastfeeding 24-hour old infant is very concerned about the techniques involved in breastfeeding. She calls the nurse with each feeding to seek reassurance that she is doing it right. She tells the nurse, "Now my daughter is not getting enough to eat." Which response would be best for the nurse to make?

• A. Feed your baby hourly until you feel confident that your child is receiving enough milk.
• B. Don't worry, soon your milk will come in, and you will feel how full your breasts are.
• C. Since you are so concerned, you should probably supplement breastfeeding with formula.
• D. If your baby's urine is straw-colored, she's getting enough milk.

Correct answer: D

Rationale: Reassuring the mother that the baby's urine color can be an indicator of adequate hydration can help her feel more confident in her breastfeeding.
