NCLEX Question of the Day – Monday, July 06, 2026

Today’s question targets early recognition of fluid volume overload and safe first nursing action in a child with a heart condition. This matters in real nursing because subtle changes like faster breathing, fewer wet diapers, or trouble feeding can signal worsening heart failure before a child looks critically ill. Nurses often catch the pattern first.

Clinical Scenario

A 6-month-old infant is admitted to the pediatric unit from the emergency department for poor feeding and increased work of breathing. The infant was born with a ventricular septal defect and is awaiting surgical repair. The parent reports that over the last 2 days, the baby tires after a few minutes of feeding, sweats during feeds, and has had fewer wet diapers. On assessment, the nurse notes a respiratory rate of 62/min, mild subcostal retractions, periorbital puffiness, and a heart rate of 168/min. The infant’s oxygen saturation is 95% on room air. Lung sounds reveal fine crackles at the bases. The provider has written routine admission orders.

The Question

Which action should the nurse take first?

Answer Choices

1. Place the infant in a supine position and prepare for a chest x-ray
2. Obtain a daily weight and compare it with the last documented weight
3. Offer a full bottle feeding now to assess feeding tolerance
4. Request a prescription for a stimulant medication to reduce fatigue during feeding

Correct Answer

B. Obtain a daily weight and compare it with the last documented weight

Detailed Rationale

This infant is showing signs of worsening heart failure related to a congenital heart defect. The key clues are poor feeding, sweating with feeds, tachypnea, retractions, fewer wet diapers, puffiness around the eyes, tachycardia, and crackles. In infants, feeding is work. If the heart cannot pump efficiently, the infant burns energy quickly, becomes tired, and may retain fluid.

The nurse should act on the most useful, safe, and immediately available assessment that helps confirm the degree of fluid retention. In pediatrics, daily weight is one of the best indicators of fluid status. Weight changes happen before obvious edema becomes severe. A small increase in weight can reflect significant fluid accumulation in an infant. Comparing the current weight with the last documented weight helps the nurse identify whether the baby is becoming fluid overloaded and gives a baseline for treatment response.

After obtaining the weight, the nurse should continue a focused assessment and notify the provider of findings that suggest heart failure progression. This includes reviewing feeding tolerance, counting wet diapers, monitoring respiratory effort, checking oxygen saturation trends, auscultating lung sounds, and watching for hepatomegaly if assessed by the provider or experienced nurse. The nurse should also cluster care, reduce energy demands, and keep feeding periods short because prolonged feeding increases oxygen consumption.

Monitoring matters here because this infant could worsen quickly. The nurse should watch for increasing crackles, rising respiratory rate, worsening retractions, decreasing intake, cyanosis, and reduced urine output. If prescribed later, common treatments may include diuretics, oxygen support, and high-calorie feeds in smaller volumes. But before treatment can be evaluated, the nurse needs a reliable baseline. Weight gives that baseline.

This is also a priority question about recognizing what is both urgent and useful. The infant is symptomatic, but not yet showing a low oxygen saturation or signs of immediate collapse. The first nursing action should be one that adds critical assessment data and supports clinical decision-making right away. Daily weight does that better than the other choices.

Why the Other Options Are Wrong

A. Place the infant in a supine position and prepare for a chest x-ray

This is not the best first action. Infants with respiratory distress usually tolerate an upright or semi-upright position better than lying flat. Supine positioning can increase work of breathing. A chest x-ray may eventually be ordered to look for cardiomegaly or pulmonary congestion, but it does not come before a priority nursing assessment and supportive positioning.

C. Offer a full bottle feeding now to assess feeding tolerance

This could make the infant worse. Full feeds require energy and can increase respiratory distress in a baby who is already tachypneic and tiring easily. Infants with suspected heart failure often need smaller, more frequent feeds or alternate nutrition plans to reduce workload. The nurse should not stress the infant just to test tolerance.

D. Request a prescription for a stimulant medication to reduce fatigue during feeding

This option does not fit the problem. The infant is fatigued because of poor cardiac output and increased metabolic demand, not because of a lack of alertness. A stimulant would not treat the cause and could worsen tachycardia. Nursing care should focus on assessing fluid status, reducing energy use, and supporting oxygenation and cardiac function.

Key Takeaways

• In infants, sweating with feeds, poor feeding, tachypnea, and fewer wet diapers are common early signs of heart failure.
• Daily weight is one of the most sensitive indicators of fluid balance.
• Crackles, puffiness, and rising respiratory effort suggest fluid overload.
• Feeding is exertion for infants. Shorter, less tiring feeds are often safer.
• Positioning matters. Avoid placing a struggling infant flat unless needed for a specific reason.

• On shift mini-checklist:
• Get and compare the current weight.
• Count respirations and assess work of breathing.
• Track intake and wet diapers carefully.
• Auscultate lungs and note crackles or changes.
• Reduce energy demands by clustering care and limiting long feeds.
• Report signs of worsening fluid overload promptly.

Quick Practice Extension

1. A toddler with congenital heart disease becomes irritable, tachypneic, and pale while crying during a blood draw. What should the nurse do first?

2. A child receiving a newly prescribed diuretic for heart failure has had two episodes of vomiting. Which assessment finding should the nurse prioritize before the next dose?
