Nursing Elites

1. 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.

2. The healthcare provider is evaluating the effects of thyroid therapy used to treat a 5-month-old with hypothyroidism. Which behavior indicates that the treatment has been effective?

• A. Laughs readily, turns from back to side.
• B. Has strong Moro and tonic neck reflexes.
• C. Keeps fists clenched, opens hands when grasping an object.
• D. Can lift head but not chest when lying on abdomen.

Correct answer: A

Rationale: In infants, laughing readily and turning from back to side are developmental milestones that indicate effective thyroid therapy and normal development. These actions demonstrate improved muscle tone, coordination, and overall growth, which are key indicators of successful treatment for hypothyroidism in infants. Choices B, C, and D describe behaviors that are not specific indicators of thyroid therapy effectiveness in treating hypothyroidism in infants.

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. 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. The nurse obtained an apical heart rate of 128 bpm, which is within the expected range for a 2-year-old child. Therefore, there is no immediate concern to withhold the scheduled dose of digoxin. Determining the pulse deficit is not necessary as the heart rate is appropriate. Calculating the safe dose range is not needed as the current dose is within the therapeutic range. Reviewing the serum digoxin level may be indicated later for monitoring but is not urgent based on the heart rate assessment. Administering the scheduled dose of digoxin is the correct action at this time.

5. A mother brings her school-aged daughter to the pediatric clinic for evaluation of her anti-epileptic medication regimen. What information should the nurse provide to the mother?

• A. The medication dose will be tapered over a period of 2 weeks when being discontinued
• B. If seizures return, multiple medications will be prescribed for another 2 years
• C. A dose of valproic acid (Depakote) should be available in the event of status epilepticus
• D. Phenytoin (Dilantin) and phenobarbital (Luminal) should be taken for life

Correct answer: A

Rationale: Antiepileptic drugs should not be abruptly stopped as it may lead to seizure recurrence. Tapering the medication over a period of 2 weeks helps to prevent withdrawal effects and minimize the risk of seizures. Choice B is incorrect because starting multiple medications for seizure recurrence is not the first-line approach. Choice C is incorrect because valproic acid is not the first-line medication given in the event of status epilepticus. Choice D is incorrect because antiepileptic medications are usually evaluated over time and adjusted based on the individual's response; it is not always necessary to take them for life.
