Question 1 of 5

The nurse is transcribing the doctor’s orders for a client with congestive heart failure. The order reads 2.5 mg of Lanoxin daily. Which action should the nurse implement?

Correct Answer: A

Rationale: Lanoxin (digoxin) 2.5 mg (
A) exceeds the safe dose (0.125–0.25 mg daily), requiring HCP clarification. Pulse (
B), potassium (
C), and digoxin level (
D) are routine but secondary to dose error.

Question 2 of 5

A female client is admitted to the hospital with obesity and deep vein thrombophlebitis (DVT) of the right leg. She weighs 275 pounds. Which of the following factors is least related to her diagnosis?

A. She has been taking oral estrogens for the last three years. B. She smokes two packs of cigarettes daily. C. Her right femur was fractured recently. D. She is 30 years old.

Correct Answer: A

Rationale: Hypokalemia (K+ 3.2,
A) increases digoxin toxicity risk, warranting caution. Digoxin level 1.2 (
B) is therapeutic, pulse 64 (
C) is normal, and no yellow haze (
D) is expected.
