Nursing Elites

1. A 2-year-old child with heart failure (HF) is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?

• A. Determine the pulse deficit.
• B. Administer the scheduled dose.
• C. Calculate the safe dose range.
• D. Review the serum digoxin level.

Correct answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario since the heart rate of 128 bpm is within an acceptable range for a 2-year-old child with heart failure. Monitoring for signs of digoxin toxicity is important; however, the immediate action required is to administer the scheduled dose as prescribed based on the heart rate assessment.

2. What information should the nurse provide to parents of a 3-year-old boy with Duchenne muscular dystrophy who inquire about the disease and future children?

• A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family
• B. The striated muscle groups of males can be impacted by a lack of the protein dystrophin in their mothers
• C. The male infant had a viral infection that went unnoticed and untreated so muscle damage was incurred
• D. Birth trauma with a breech vaginal birth causes damage to the spinal cord, thus weakening the muscles

Correct answer: A

Rationale: Duchenne muscular dystrophy is an X-linked recessive disorder caused by mutations in the DMD gene on the X chromosome. This disorder primarily affects males because they have one X chromosome, inherited from their mothers, who may be carriers of the mutated gene. Females have two X chromosomes, providing a protective effect as the normal gene on one X chromosome can compensate for the mutated gene on the other. Therefore, the nurse should explain to the parents that Duchenne muscular dystrophy is an inherited X-linked recessive disorder, which is why their son has the disease and why there is a risk of passing it on to future sons. Choice B is incorrect as it inaccurately implies that the lack of dystrophin in mothers impacts their sons' muscle groups. Choice C is incorrect as it suggests a viral infection caused the muscle damage, which is not the case with Duchenne muscular dystrophy. Choice D is incorrect as it attributes the muscle weakness to birth trauma instead of the genetic nature of the disorder.

3. A 4-year-old child with a history of frequent ear infections is brought to the clinic by the parents who are concerned about the child’s hearing. What is the nurse’s priority action?

• A. Perform a hearing test
• B. Inspect the child’s ears for drainage
• C. Refer the child to an audiologist
• D. Ask the parents about the child’s speech development

Correct answer: B

Rationale: The nurse's priority action should be to inspect the child's ears for drainage. This immediate assessment can provide valuable information about the presence of infection or fluid accumulation, which can directly impact the child's hearing. By identifying any signs of drainage, the nurse can promptly address any current issues affecting the child's ear health and hearing abilities. Performing a hearing test (Choice A) may be necessary but should follow the initial assessment of the ears. Referring the child to an audiologist (Choice C) can be considered later based on the findings. Asking about speech development (Choice D) is important but not the immediate priority compared to assessing for current ear issues.

4. The mother of a 4-month-old asks the nurse for advice in preventing diaper rash. What suggestion should the nurse provide?

• A. At diaper change generously powder the baby's diaper area with talcum powder to promote dryness.
• B. Wash the diaper area every 2 hours with soap and water to help prevent skin breakdown.
• C. Use a barrier cream, such as zinc oxide, which does not have to be completely removed with each diaper change.
• D. Place a cloth diaper inside the disposable diaper for overnight periods when increased wearing time is likely.

Correct answer: C

Rationale: Using a barrier cream like zinc oxide protects the skin and helps prevent diaper rash.

5. The parents of a 4-year-old child who has just been diagnosed with celiac disease are being educated by a healthcare provider. Which statement by the parents indicates a correct understanding of the condition?

• A. We can give our child small amounts of gluten occasionally
• B. We need to avoid giving our child foods containing wheat, barley, and rye
• C. We should limit our child’s intake of dairy products
• D. Our child will need to take gluten-free supplements

Correct answer: B

Rationale: Choice B is the correct answer because for individuals with celiac disease, a strict gluten-free diet is essential for managing the condition. Foods containing wheat, barley, and rye must be completely avoided to prevent adverse reactions and damage to the intestines. This dietary restriction is crucial to ensure the child's health and well-being in managing celiac disease effectively. Choices A, C, and D are incorrect because giving small amounts of gluten occasionally, limiting dairy products, or taking gluten-free supplements are not sufficient measures to manage celiac disease. Complete avoidance of gluten-containing foods is necessary to prevent complications.
