Answer to Question 1

C
Although cranberry juice or cola beverages are sometimes used to reduce the incidence of tube occlusion, water is the preferred irrigant because it has been shown to be superior in maintaining tube patency.

Answer to Question 2

A
Korotkoff sounds are the sounds created by turbulence of blood flow within a vessel caused by constriction of the blood pressure cuff. Pulse pressure describes the difference between systolic and diastolic values. The normal pulse pressure is 40 mm Hg. Abnormal heart sounds are known as the third heart sound (S3) and the fourth heart sound (S4); they are referred to as gallops when auscultated during an episode of tachycardia. Murmurs are produced by turbulent blood flow through the chambers of the heart, from forward flow through narrowed or irregular valve openings, or backward regurgitate flow through an incompetent valve.
