Answer to Question 1

A

Feedback
A Correct. Multisystem vasculitis that tends to affect the coronary arteries best describes the pathophysiology of KD.
B Incorrect. Poor circulation due to faulty valves that primarily affects the extremities does not best describe the pathophysiology of KD.
C Incorrect. Hypertrophy of the heart causing arrhythmias does not best describe the pathophysiology of KD.
D Incorrect. Electrolyte imbalance causing faulty firing of the heart does not best describe the pathophysiology of KD.

Answer to Question 2

C
The nurse would chose the vastus lateralis, because it is well-developed at birth, the largest muscle mass and has the fewest vessels and nerves. The dorsogluteal is not fully developed until the child has walked for 1 to 2 years. The ventrogluteal should not be used until 18 months. The deltoid can't be used to hold large volumes of medication, nor for medications that need to be administered into the deep muscle mass.
