2Administer antipyretic medication to reduce fever and improve appetite
3Monitor fluid balance and assess for signs of dehydration✓ 정답
4Isolate the child completely to prevent transmission to family members
해설
Children with decreased oral intake are at high risk for dehydration due to higher metabolic rates and smaller fluid reserves. Priority is monitoring fluid balance and assessing for signs of dehydration. Other options address nutrition or isolation but do not address the immediate risk of dehydration.
Understanding the Priority: Fluid Balance Over Other Interventions
In a 4-year-old child with COVID-19 presenting with persistent fever, fatigue, and decreased oral intake over 3 days, the priority nursing intervention is to monitor fluid balance and assess for signs of dehydration. While all the listed options represent important aspects of care, the physiological vulnerability of young children to fluid and electrolyte imbalances makes this the most time-sensitive and critical action according to the ABC (Airway, Breathing, Circulation) and safety prioritization frameworks used in NCLEX-RN.
Pathophysiology and Clinical Reasoning
Fever increases the body’s metabolic rate and insensible water loss through the skin and respiratory tract. When this is combined with decreased oral intake, a young child can rapidly progress from a state of compensated dehydration to hypovolemic shock. A 4-year-old has a higher body surface area-to-volume ratio and a faster metabolic turnover than an adult, which accelerates the development of dehydration. The reported symptom of fatigue is a key clinical indicator that may reflect not only the viral illness itself but also the early hemodynamic effects of volume depletion, such as decreased cardiac preload and reduced cerebral perfusion.
The provided case report on a pediatric patient with a co-infection including SARS-CoV-2 explicitly highlights the clinical significance of this principle. In that case, a febrile infant with gastrointestinal losses presented with moderate dehydration, and the cornerstone of initial management was rehydration and supportive care [2]. This directly mirrors the current scenario, where the combination of persistent fever and poor intake creates a high-risk state for a significant fluid volume deficit. Assessing hydration status—by evaluating mucous membranes, skin turgor, capillary refill, urine output, and vital signs including orthostatic heart rate changes—provides the essential data needed to guide all subsequent interventions.
Analyzing the Alternative Options
The other options, while not incorrect in a broader care plan, are not the immediate priority.
- Encouraging favorite foods addresses nutrition, which is important for healing. However, in the acute phase of illness with fever and fatigue, a child’s gastrointestinal motility is often slowed, and the immediate physiological threat is fluid volume deficit, not caloric malnutrition. Forcing foods could induce vomiting, worsening fluid loss and causing distress. The priority is to first stabilize the circulatory volume by promoting fluid intake in any tolerated form.
- Administering an antipyretic is a common comfort measure that may secondarily improve oral intake by reducing fever-related malaise. However, it is a pharmacological intervention that requires a prior assessment of hydration status. Administering medication like acetaminophen to a significantly dehydrated child could potentially concentrate the drug in a reduced plasma volume and compromise renal perfusion, increasing the risk of toxicity. The nursing process dictates assessment before intervention, making fluid status evaluation the necessary preceding step.
- Complete isolation is a critical infection control measure for COVID-19. However, this is an environmental and public health intervention, not a direct physiological priority for the individual child in the acute care setting. The child’s immediate physical safety from hypovolemia takes precedence over the transmission prevention measure, which can be implemented concurrently but does not constitute the first nursing action to address the child’s presenting symptoms of fatigue and decreased intake.
Integration of Evidence and NCLEX-RN Application
The broader literature on pediatric infections in the post-pandemic era reinforces that the primary clinical challenge in febrile respiratory illnesses is often the management of fluid and metabolic consequences. A review of pediatric RSV co-infections notes that bacterial and viral co-pathogens can complicate the clinical course, but the foundational supportive care remains centered on maintaining hydration and oxygenation . The specific case of a pediatric patient with a SARS-CoV-2 co-infection demonstrated that clinical improvement was achieved through a care plan prioritizing rehydration alongside antimicrobial therapy [2]. This evidence supports the nursing judgment that for a child with days of fever and poor intake, the most immediate threat to physiological integrity is a disruption in fluid and electrolyte balance. The nursing intervention of monitoring fluid balance and assessing for dehydration directly targets this threat, providing the critical data needed to prevent clinical deterioration and guide the next steps in care.

Key Clinical Pearl
In a young child with fever and reduced oral intake, fluid volume deficit can develop rapidly due to a higher body surface area-to-volume ratio and increased metabolic rate. The priority is always to assess and maintain circulation by monitoring fluid balance and signs of dehydration before addressing other concerns like nutrition or fever reduction.
Severe (>10% loss): Marked sunken eyes and fontanelle, very delayed capillary refill (>3 seconds), hypotension, lethargy, oliguria or anuria.
Nursing Priority Interventions
Initiate strict intake and output (I&O) monitoring, including weighing wet diapers.
Obtain daily weights using the same scale to track acute fluid loss (1 kg weight loss ≈ 1 L fluid loss).
Offer small, frequent sips of an oral rehydration solution (ORS) rather than plain water to replace electrolytes.
Continuously reassess vital signs with a focus on heart rate and blood pressure for early signs of compensated shock.
When to Escalate Care
Immediately notify the provider if the child develops any signs of moderate to severe dehydration, including altered mental status, inability to tolerate oral fluids, or if urine output drops below 1 mL/kg/hour.
Insensible water loss — Fluid loss that occurs through the skin and respiratory tract, which is increased during fever and can rapidly contribute to dehydration in young children.

Hypovolemic shock — A life-threatening condition caused by a severe drop in blood volume, leading to inadequate oxygen delivery to tissues, which can result from untreated dehydration.
