NCLEX Question of the Day – Thursday, May 28, 2026

Today’s question targets priority setting in Pediatrics, especially early recognition of dehydration in a child with vomiting and diarrhea. This matters in real nursing because children can lose fluid fast, and the first signs of trouble are often subtle. A nurse who catches worsening perfusion early can prevent shock, IV escalation delays, and serious electrolyte problems.

Clinical Scenario

A 3-year-old child is brought to an urgent care clinic by a parent after 2 days of vomiting and frequent watery stools. The child has had very little to drink since last evening. The parent says, “He just wants to sleep and cries without tears.”

The child weighs 14 kg. History includes no chronic illness and no daily medications. On assessment, the nurse notes a heart rate of 148/min, respiratory rate of 28/min, dry oral mucosa, cool hands, capillary refill of 4 seconds, and only one small wet diaper in the past 10 hours. The child is drowsy but arouses to voice. Temperature is 37.3 C (99.1 F), and blood pressure is 88/54 mm Hg.

The Question

Which action should the nurse take first?

Answer Choices

1. Offer small sips of oral rehydration solution every 5 minutes
2. Place the child on daily weights and begin strict intake and output recording
3. Notify the provider immediately and prepare for rapid isotonic IV fluid replacement
4. Administer an antidiarrheal medication as prescribed to reduce fluid loss

Correct Answer

C. Notify the provider immediately and prepare for rapid isotonic IV fluid replacement

Detailed Rationale

This child is showing signs of severe dehydration with poor perfusion. The nurse should recognize this as a priority problem and act quickly.

Several findings point to more than mild fluid loss:

• Tachycardia at 148/min
• Delayed capillary refill of 4 seconds
• Cool extremities, which suggest reduced peripheral perfusion
• Dry mucous membranes
• Minimal urine output over 10 hours
• Drowsiness, which is concerning in a child with fluid loss

In pediatrics, mental status and perfusion changes matter a lot. A child may keep blood pressure in the normal range until late, then decline quickly. This child’s blood pressure is already on the low side for age, which adds urgency.

The first nursing priority is to support circulation. That is why the nurse should immediately escalate care and prepare for isotonic IV fluids, such as normal saline, based on the provider’s orders or emergency protocol. Oral rehydration is useful in mild to moderate dehydration, but this child has signs that suggest oral intake alone is no longer the safest first step.

After recognizing the severity, the nurse should assess and do the following:

• Reassess airway, breathing, and circulation
• Check level of responsiveness and ability to protect the airway
• Obtain full vital signs and repeat them frequently
• Monitor capillary refill, skin temperature, pulses, and urine output
• Prepare for IV access and fluid bolus
• Anticipate laboratory work if ordered, such as electrolytes and glucose

The nurse should also monitor the child for improvement after fluids. Signs of response include lower heart rate, improved alertness, warmer extremities, faster capillary refill, and increased urine output. These findings tell the nurse that perfusion is getting better.

The key reason this option comes first is simple: circulation problems come before routine monitoring or slower treatments. In NCLEX priority questions, the best answer is the one that addresses the immediate threat.

Why the Other Options Are Wrong

A. Offer small sips of oral rehydration solution every 5 minutes

This is a good intervention for a child with mild or some moderate dehydration who is alert, stable, and able to tolerate oral fluids. It is not the best first step here because this child has poor perfusion, lethargy, and very low urine output. Waiting on oral fluids could delay needed circulatory support.

B. Place the child on daily weights and begin strict intake and output recording

This is appropriate and important, but it is not first. Intake and output and weights help track fluid balance over time. They do not correct the immediate perfusion deficit. In an unstable child, treatment comes before routine measurement tasks.

D. Administer an antidiarrheal medication as prescribed to reduce fluid loss

This is not the priority, and antidiarrheals are not routinely used in young children with acute gastroenteritis. They can mask symptoms, may have side effects, and do not address the urgent issue, which is fluid volume loss and impaired perfusion.

Key Takeaways

• In children, tachycardia, delayed capillary refill, cool extremities, decreased urine output, and lethargy are major warning signs of worsening dehydration.
• Oral rehydration works well for mild to moderate cases, but signs of poor perfusion call for rapid escalation.
• Do not be falsely reassured by a child who is “just sleepy.” In dehydration, decreased alertness can signal serious decline.
• Priority thinking: treat the immediate circulation problem before focusing on longer-term monitoring tasks.

What you’d do on shift:

• Recognize red flags fast
• Reassess ABCs and perfusion
• Get help early and notify the provider
• Prepare for isotonic IV fluids
• Trend vital signs, mental status, cap refill, and urine output

Quick Practice Extension

1. A 4-year-old with vomiting is alert, has moist mucous membranes, and urinates every 6 hours. Which finding would make oral rehydration appropriate instead of IV fluid replacement?
2. After an IV fluid bolus, which reassessment finding best suggests the child’s perfusion is improving?

Question style tip: When an NCLEX item asks what to do first, look for signs of airway, breathing, circulation, or decreased level of consciousness. In pediatric dehydration, perfusion clues often matter more than the number of stools or episodes of vomiting.
