Answer to Question 1

A
Atrial fibrillation and atrial flutter both involve an abnormally fast atrial depolarization rate, while the ventricular rate is less than the atrial rate. Sinus bradycardia is a heart rate of less than 60 bpm. Sinus tachycardia is a very fast ventricular rate that matches the atrial rate.

Answer to Question 2

D
Kyphosis is a posterior curve of the spine (humpback).
