Nursing Elites

1. What information should the nurse provide the parents of a 3-year-old boy with Duchenne muscular dystrophy (DMD) who are concerned about having more children?

• A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family.
• B. The male infant had a viral infection that went unnoticed and untreated, leading to muscle damage.
• C. The mother's lack of the protein dystrophin can impact the XXXX muscle groups in males.
• D. Birth trauma during a breech vaginal birth can damage the spinal cord, resulting in muscle weakness.

Correct answer: A

Rationale: The correct answer is A. Duchenne muscular dystrophy is an inherited X-linked recessive disorder that primarily affects male children in the family. Since it is X-linked, sons inherit the mutation from their mothers who are carriers of the abnormal gene. Therefore, the nurse should explain to the parents that any future sons they have would have a 50% chance of inheriting the mutation and having DMD, while daughters would have a 50% chance of being carriers like the mother.

2. A 6-year-old boy with bronchial asthma takes the beta-adrenergic agonist albuterol (Proventil). The child’s mother tells the nurse that she uses this medication to open her son’s airway when he is having trouble breathing. What is the nurse’s best response?

• A. Recommend that the mother bring the child in for immediate evaluation
• B. Advise the mother that overuse of the drug may cause chronic bronchitis
• C. Assure the mother that she is using the medication correctly
• D. Confirm that the medication helps to reduce airway inflammation

Correct answer: C

Rationale: The correct response is to assure the mother that she is using the medication correctly. Albuterol is a beta-adrenergic agonist that helps open the airways during an asthma attack. By reassuring the mother, the nurse reinforces the correct usage of the medication, which is crucial in managing the child's asthma symptoms effectively. Option A is incorrect because immediate evaluation may not be necessary if the child's symptoms are being managed effectively with albuterol. Option B is incorrect as chronic bronchitis is not typically associated with the overuse of albuterol. Option D is incorrect as albuterol primarily acts as a bronchodilator and does not directly reduce airway inflammation.

3. The healthcare provider is preparing to administer a scheduled dose of digoxin to a 4-year-old child with heart failure. The healthcare provider notes that the child’s heart rate is 70 beats per minute. What should the healthcare provider do next?

• A. Administer the medication as prescribed
• B. Hold the medication and notify the healthcare provider
• C. Recheck the heart rate in 30 minutes
• D. Administer half of the prescribed dose

Correct answer: B

Rationale: In pediatric patients, digoxin administration is guided by the heart rate. If the child's heart rate is below the established threshold, which is typically 90-100 beats per minute in a 4-year-old, the medication should be withheld, and the healthcare provider should be notified for further evaluation and instructions. Choice A is incorrect because administering the medication when the heart rate is low can lead to adverse effects. Rechecking the heart rate in 30 minutes (Choice C) may delay necessary intervention if the heart rate remains low. Administering half of the prescribed dose (Choice D) is not recommended without healthcare provider guidance.

4. What is the priority intervention for a 16-year-old client with a history of depression who is brought to the emergency department after taking an overdose of acetaminophen?

• A. Administer activated charcoal
• B. Place the client on continuous cardiac monitoring
• C. Prepare for gastric lavage
• D. Administer N-acetylcysteine as prescribed

Correct answer: D

Rationale: The priority intervention for a client who has taken an acetaminophen overdose is to administer N-acetylcysteine promptly. N-acetylcysteine is the antidote for acetaminophen overdose and helps prevent liver damage. Activated charcoal may be used in certain cases, but N-acetylcysteine takes precedence as it directly counteracts the toxic effects of acetaminophen. Continuous cardiac monitoring and gastric lavage are not the priority interventions for acetaminophen overdose. Administering N-acetylcysteine is crucial to prevent liver damage and address the overdose, making it the most urgent action in this scenario.

5. A two-year-old child with heart failure 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 as the heart rate of 128 bpm falls within the acceptable range for a two-year-old child with heart failure. It indicates that the child may benefit from the therapeutic effects of digoxin. Monitoring the heart rate closely after administration is essential to ensure the medication's effectiveness and safety. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is within the acceptable range. Calculating the safe dose range (Choice C) is not needed since the heart rate is already within the expected parameters. Reviewing the serum digoxin level (Choice D) is not the immediate action required in this case where the heart rate is within the normal range.
