of the following findings should the nurse identify as an early sign of digoxin
toxicity?
A. Yellow-tinged vision
B. Tachycardia
C. Increased appetite
D. Hypokalemia
Answer: A
Rationale: Early signs of digoxin toxicity often include gastrointestinal disturbances like

,3. The nurse is caring for a client diagnosed with pulmonary tuberculosis. Which
type of precautions should the nurse implement?
A. Droplet precautions
B. Contact precautions
C. Standard precautions only

is most important for the nurse to keep at the bedside?
A. A heating pad
B. A portable chest tube drainage system
