Nursing Elites

1. The parents of a 3-year-old boy with Duchenne muscular dystrophy (DMD) ask, 'How can our son have this disease? We are wondering if we should have any more children.' What information should the nurse provide these parents?

• 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 lack of the protein dystrophin in the mother can impact the XXX muscle groups of males.
• D. Spinal cord damage due to birth trauma during a breech vaginal birth weakens the muscles.

Correct answer: A

Rationale: The correct answer is A. Duchenne muscular dystrophy is an X-linked recessive disorder, meaning the gene mutation causing DMD is located on the X chromosome. Males have one X chromosome and one Y chromosome, so if the X chromosome they inherit from their mother carries the mutated gene, they will develop DMD. Females have two X chromosomes, so they are carriers of the gene but are usually not affected by the disease. Therefore, the nurse should explain to the parents that DMD is an inherited X-linked recessive disorder that primarily affects male children in the family.

2. A 6-week-old infant diagnosed with pyloric stenosis has recently developed projectile vomiting. Which assessment finding indicates to the nurse that the infant is becoming dehydrated?

• A. Weak cry without tears.
• B. Bulging fontanel.
• C. Visible peristaltic wave.
• D. Palpable mass in the right upper quadrant.

Correct answer: A

Rationale: In infants, a weak cry without tears is a classic sign of dehydration. Tears are produced by the lacrimal glands, and reduced tear production is a result of dehydration. This assessment finding should alert the nurse to the infant's dehydration status, requiring prompt intervention to prevent further complications.

3. When assessing a child with HIV, which system should the nurse assess first?

• A. Assess the respiratory system.
• B. Assess the gastrointestinal system.
• C. Assess the cardiovascular system.
• D. Assess the neurological system.

Correct answer: A

Rationale: When assessing a child with HIV, it is essential to prioritize assessing the respiratory system first. Children with HIV are more susceptible to respiratory infections and complications, such as pneumonia, due to their weakened immune system. Identifying any respiratory issues early on can help in prompt intervention and management, thus improving outcomes for the child.

4. The healthcare provider is preparing to administer magnesium sulfate to a laboring client whose blood pressure has increased from 110/60 mmHg to 140/90 mmHg. Which action is the highest priority?

• A. Provide a quiet environment with subdued lighting.
• B. Have calcium gluconate immediately available.
• C. Assess deep tendon reflexes (DTRs) every 4 hours.
• D. Insert a Foley catheter with a urimeter to monitor hourly output.

Correct answer: B

Rationale: Having calcium gluconate readily available is crucial when administering magnesium sulfate, as it serves as the antidote in case of magnesium toxicity. Magnesium sulfate can lead to respiratory depression and cardiac arrest in cases of overdose or toxicity, making the prompt availability of calcium gluconate essential for immediate administration to counteract these effects. Providing a quiet environment with subdued lighting may be beneficial for the client's comfort but is not the highest priority in this situation. Assessing deep tendon reflexes every 4 hours is important when administering magnesium sulfate, but it is not the highest priority compared to having calcium gluconate available. Inserting a Foley catheter with a urimeter to monitor hourly output is not the highest priority when preparing to administer magnesium sulfate in this scenario.

5. The nurse is caring for a 5-year-old child with Reye’s syndrome. Which goal of treatment most clearly relates to caring for this child?

• A. Reduce cerebral edema and lower intracranial pressure
• B. Avert hypotension and septic shock
• C. Prevent cardiac arrhythmias and heart failure
• D. Promote kidney perfusion and normal blood pressure

Correct answer: A

Rationale: Reducing cerebral edema and lowering intracranial pressure is the primary goal of treatment for Reye’s syndrome.
