In treating a patient with congestive heart failure you have

In treating a patient with congestive heart failure, you have prescribed digoxin (a cardiac glycoside) to strengthen the heart\'s output and maintain a regular rate. The target of this drug is the Question 8 options: A. ATP synthase. B. Na+, K+ - ATPase. C. ligand - gated Ca2+ channel. D. resting K+ channel. E. voltage - gated Na+ channel.

Solution

Answer:

(B) Na+,K+, ATPase

Explanation: In a patient with congestive heart failure, digoxin strengthens the heart\'s output by inhibiting sodium-potassium-adenosine triphospate (Na+, K+, ATPase), which in cardiac cells results in an increase in the contractile state of the heart (i.e. hepls to contract the heart).
