## Question

Stage 6 — Evaluate outcomes. Review the clinical and echocardiographic trend and select the best interpretation and response.

| Time | Data |
| --- | --- |
| Before IVIG | Temperature 39.1 C; irritable; LAD coronary Z-score 2.7 |
| 24 hours after IVIG | Temperature 37.2 C; drinking fluids; irritability improved |
| 40 hours after IVIG | Temperature 38.7 C returns; CRP remains elevated |
| Follow-up echo | LAD coronary Z-score increases to 3.2 |

Q1. Which interpretation is best supported?

The child has a complete response with no cardiac risk
The fever is an expected harmless IVIG reaction
The child may have IVIG-resistant disease with increasing coronary involvement
The initial diagnosis is excluded

Q2. Which response is the priority?

Notify the pediatric cardiology team and prepare prescribed additional anti-inflammatory treatment
Discharge because the child was previously afebrile
Stop all coronary imaging
Give an unsupervised over-the-counter antipyretic and reassess next week

## Explanation

Recurrent fever after initial response plus an increasing coronary Z-score indicates incomplete treatment response and greater coronary risk. The nurse should promptly notify the team and prepare for additional anti-inflammatory treatment and risk-directed cardiac care.

## In-depth explanation

Quick answer
Recurrent fever and worsening coronary measurements mean the response is inadequate and escalation is required.

Why this is correct
The trend combines clinical relapse with objective coronary progression, both of which change the plan.

Easy analogy or mental picture
The fever alarm returns while the coronary gauge moves in the wrong direction.

Memory hook
Fever returns plus Z-score rises equals escalate.

NCLEX decision rule
Evaluate response with symptoms and objective organ data; a temporary improvement does not close the case.

Why the other choices are wrong
Prior defervescence does not justify discharge when fever recurs, and worsening coronary findings require continued imaging and specialist treatment.

## Clinical scenario

Case update
The child initially becomes afebrile after IVIG, but fever and coronary findings recur during observation.
