Answer to Question 1

ANS: D
Normally, the difference between the PCO2 measured at the end of a maximum exhalation and the PaCO2 is minimal. Patients with chronic obstructive pulmonary disease or left-sided heart failure do not show an increase in this difference. However, patients with pulmonary embolism show an increased gradient.

Answer to Question 2

ANS: C
Automaticity describes the ability of certain specialized cells of the heart to depolarize. Diastasis refers to the long period of reduced ventricular filling that follows the rapid-filling period. Excit-ability is defined as the ability of a cell to respond to an electrical stimulus. Conductivity is de-fined as the ability of cardiac tissue to propagate an action potential.

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.
