A 5-year-old child with confirmed COVID-19 presents to the pediatric unit. Which assessment finding would be the MOST concerning and require immediate nursing intervention?

## 보기

1. Mild cough with clear sputum production and temperature of 100.2°F (37.9°C)
2. Persistent vomiting, abdominal pain, and conjunctival injection with strawberry tongue **✔ 정답**
3. Fatigue and decreased appetite lasting for 3 days with normal vital signs
4. Intermittent headache and myalgia with oxygen saturation of 97% on room air

**정답: 2**

## 해설

Persistent vomiting, abdominal pain, conjunctival injection, and strawberry tongue are signs of MIS-C, a serious post-COVID complication requiring urgent intervention. Other options represent common or mild COVID-19 symptoms.

Understanding the Priority Assessment in Pediatric COVID-19

The question asks you to identify the most concerning assessment finding in a 5-year-old with confirmed COVID-19. This requires you to move beyond common, expected viral symptoms and recognize a cluster of findings that signals a life-threatening post-infectious complication. The correct answer is option 2.

Why Persistent Vomiting, Abdominal Pain, and Conjunctival Injection with Strawberry Tongue is the Priority

This combination of symptoms is highly specific for a severe hyperinflammatory condition called Multisystem Inflammatory Syndrome in Children (MIS-C). MIS-C is an emergent postinfectious disorder that occurs weeks after a SARS-CoV-2 infection and can rapidly progress to shock and multiorgan failure [1]. The clinical presentation you see in option 2—persistent vomiting, abdominal pain, conjunctival injection, and strawberry tongue—represents a phenotypic overlap with Kawasaki Disease (KD), and research indicates that 25-50% of MIS-C cases may meet the full criteria for KD [4].

The immediate concern is not just the gastrointestinal distress, but the underlying systemic inflammation that can cause myocarditis and cardiovascular collapse. Cardiac involvement is a critical clinical concern in MIS-C, occurring in 67%-80% of cases [2]. A child presenting with these mucocutaneous and gastrointestinal signs is at high risk for rapid deterioration, including hypotension and shock, which demands immediate nursing intervention such as notifying the provider, establishing IV access, and preparing for cardiac monitoring and fluid resuscitation [1].

Analyzing the Other Options

To solidify your clinical judgment, it is crucial to understand why the other findings are less immediately life-threatening in this context.

*   Option 1: Mild cough with clear sputum production and temperature of 100.2°F (37.9°C). This presentation is consistent with a typical, mild viral upper respiratory infection. A low-grade fever and mild cough are expected symptoms of an acute COVID-19 infection and do not, by themselves, signal a hyperinflammatory emergency. Supportive care and routine monitoring are appropriate here.

*   Option 3: Fatigue and decreased appetite lasting for 3 days with normal vital signs. Fatigue and anorexia are common, nonspecific constitutional symptoms in children with any viral illness. The key reassuring factor here is the presence of normal vital signs. While these symptoms warrant continued observation and supportive measures like encouraging fluid intake, the hemodynamic stability indicates that this is not an immediate priority over a presentation suspicious for MIS-C.

*   Option 4: Intermittent headache and myalgia with oxygen saturation of 97% on room air. Headache and muscle aches are frequent complaints with COVID-19. The oxygen saturation of 97% on room air is a normal finding and effectively rules out acute respiratory failure as an immediate concern. While the nurse should provide comfort measures, this stable respiratory and neurological presentation does not indicate the need for urgent, life-saving intervention.

The critical distinction lies in recognizing that MIS-C is a distinct clinical entity from acute COVID-19, characterized by a dysregulated immune response that can present with atypical, prolonged, or relapsing fevers and a wide spectrum of severe manifestations . Differentiating MIS-C from similar conditions like KD is clinically important for timely and appropriate management to prevent long-term cardiac sequelae [4]. The cluster of symptoms in option 2 is the classic warning sign you must act on immediately.References (research sources)

Recognizing MIS-C in Pediatric COVID-19Immediate nursing actions for the hyperinflammatory emergency
The cluster of persistent vomiting, abdominal pain, conjunctival injection, and strawberry tongue in a child with recent COVID-19 is a classic presentation of Multisystem Inflammatory Syndrome in Children (MIS-C). This is a severe postinfectious hyperinflammatory condition, not just a gastrointestinal illness.

Cardiac involvement occurs in 67%-80% of MIS-C cases, leading to myocarditis and rapid progression to cardiogenic shock. The immediate nursing priority is continuous cardiorespiratory monitoring, obtaining a full set of vital signs including blood pressure, and notifying the provider to prepare for potential vasopressor support and transfer to a higher level of care.

CautionDo not dismiss these symptoms as a routine viral gastroenteritis. Delayed recognition of MIS-C can lead to irreversible myocardial dysfunction and coronary artery dilation. Early echocardiography and inflammatory marker labs (CRP, ferritin) are critical.

## 핵심 개념

- **Multisystem Inflammatory Syndrome in Children (MIS-C)** — A rare but severe post-infectious hyperinflammatory condition following SARS-CoV-2 infection, causing fever, multisystem organ involvement, and potential cardiovascular collapse.
- **Strawberry Tongue** — An erythematous, edematous tongue with prominent papillae, a classic mucocutaneous sign associated with Kawasaki Disease and MIS-C.
- **Kawasaki Disease (KD)** — An acute, self-limited vasculitis of childhood that is a clinical differential for MIS-C, characterized by fever, conjunctivitis, rash, and coronary artery aneurysms.
- **Conjunctival Injection** — Redness of the conjunctiva, typically bilateral and non-exudative, a key diagnostic criterion for both Kawasaki Disease and MIS-C.
- **Postinfectious Complication** — A disorder triggered by an immune response weeks after the initial infection has resolved, rather than by direct viral damage.
