Answer to Question 1

A
Sleep onset usually occurs in stage 1 sleep, progressing through stages 2 and 3 and then going back to stage 2, at which time the person usually enters REM.

Answer to Question 2

A
The abdominojugular reflux sign can assist with the diagnosis of right ventricular failure. A positive abdominojugular reflux sign is an increase in the jugular venous pressure (CVP equivalent) of greater than 3 cm sustained for at least 15 seconds.
