Answer to Question 1

C
Feedback:
The CTZ is composed of neurons in the fourth ventricle. The vomiting center is a nucleus of cells in the medulla oblongata. Stimuli are relayed to the vomiting center by afferent signals from the chemoreceptor trigger zone (CTZ).

Answer to Question 2

B
Feedback:
Hypokalemia will contribute to the patient developing digoxin toxicity. Hyperkalemia, hypermagnesemia, and hyponatremia will not contribute to the development of digoxin toxicity.
