What is the purpose of the beta blocker carvedilol? It is given to: l. Increase the contractility of the heart m. Cause peripheral dilation n. Increase urine output o. Reduce cardiac stimulation by catecholamines ii. Answer: B

Case Study Progress
The next day M.G. has shown only slight improvement, and digoxin (lanoxin) 125 mcg po daily is added to her orders.

8. What is the action of the digoxin? Digoxin: p. Causes systemic vasodilation q. Promotes the excretion of sodium and water in the renal tubules r. Increases cardiac contractility and cardiac output s. Blocks sympathetic nervous system stimulation to the heart iii. Answer: C

9. Which findings from M.G.’s assessment would indicate an increased possibility of digoxin toxicity? Explain your answer t. Serum potassium level of 2.2 meq/l u. Serum sodium level of 139 meq/l v. Apical heart rate of 64 beats/minute w. Digoxin level 1.6 ng/ml iv. Answer: A

10. When you go to give the digoxin, you notice that it is available in milligrams not micrograms. Convert 125 mcg to mg. x. Answer: 0.125 mg
