During a stress test on a treadmill, which observation by the nurse would necessitate immediate action?

Choice A rationale
Cracked lips are a symptom of Kawasaki disease, but they are more commonly associated with the subacute phase of the disease, not the acute phase.
Choice B rationale
Conjunctival hyperemia, or redness of the whites of the eyes, is a common symptom in the acute phase of Kawasaki disease. It typically presents as bilateral, non-exudative conjunctival injection, primarily in the bulbar conjunctivae.
Choice C rationale
A normal appearance is not typically seen in the acute phase of Kawasaki disease, which is characterized by a high fever and at least four of the five main symptoms, including conjunctival hyperemia.
Choice D rationale
Desquamation of the skin, or peeling, is a symptom of Kawasaki disease, but it typically occurs in the subacute phase, not the acute phase.

Choice A rationale
Atrial Flutter is a type of arrhythmia where the atria beat regularly, but much faster than usual. The treatment for Atrial Flutter is typically medication, not cardioversion.
Choice B rationale
Ventricular Tachycardia is a fast, abnormal heart rate. It starts in your heart’s lower chambers, or ventricles. Ventricular Tachycardia is a serious condition and can be life-threatening. While cardioversion can be used in some cases, it is not the primary treatment.
Choice C rationale
Atrial Fibrillation is when the upper chambers of the heart (atria) beat irregularly. This causes the atria to twitch, leading to an abnormal heart rhythm. The treatment for Atrial Fibrillation is typically medication, not cardioversion.
Choice D rationale
Ventricular Fibrillation is a life-threatening heart rhythm that results in a rapid, erratic heartbeat. During Ventricular Fibrillation, the heart quivers and can’t pump any blood, causing cardiac arrest. The treatment for Ventricular Fibrillation is Defibrillation.
