Question 1 of 5.
The nurse is preparing to administer digoxin (Lanoxin) to a client with heart failure. Which finding would require the nurse to withhold the dose?
A. Apical pulse of 56 beats per minute
B. Blood pressure of 130/80 mmHg
C. Potassium level of 4.0 mEq/L
D. Serum digoxin level of 1.2 ng/mL
Explanation: Digoxin is withheld if the apical pulse is below 60 beats per minute in adults, as bradycardia increases the risk of toxicity. The other findings are within normal ranges for digoxin administration.
Question 2 of 5.
A client hospitalized with cirrhosis has developed abdominal ascites. The nurse should provide the client with snacks that provide additional:
A. Sodium
B. Potassium

A. Ignore the client's behavior.
B. Exchange the cards for a checker board.

A. Loss of the myelin sheath in portions of the brain and spinal cord
B. An interruption in the transmission of impulses from nerve endings to muscles
