Answer to Question 1

Ans: B, C, D
Feedback:
Verapamil (Calan) is a calcium channel blocker. These drugs inhibit the movement of calcium through channels across the myocardial cell membranes and vascular smooth muscle. Cardiac and vascular smooth muscle depends on the movement of calcium ions into the muscle cells through specific ion channels. When this movement is inhibited, the coronary and peripheral arteries dilate, thereby decreasing the force of cardiac contraction. This drug also reduces heart rate by slowing conduction through the SA and AV nodes.

Answer to Question 2

Ans: A, D, E
Feedback:
The preadministration assessment of the client's general condition should include observations such as skin color, orientation, level of consciousness, and the client's general status.
