A. Heart rate 72 bpm
B. Anorexia, nausea, and yellow-green halos
C. Blood pressure 120/80 mmHg
D. Serum digoxin level 1.0 ng/mL
Answer: B
Rationale: Early toxicity includes GI symptoms (anorexia,
nausea, vomiting) and visual disturbances (yellow-green halos).
Therapeutic level 0.5–2.0 ng/mL.
,2. A client on warfarin (Coumadin) has an INR of 4.5. No
bleeding is present. What should the nurse do first?
A. Administer vitamin K
B. Hold the next dose and notify the healthcare provider

very high.
3. A client receives furosemide (Lasix) IV push. Which
electrolyte imbalance is most concerning?
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hypocalcemia
Answer: B
Rationale: Furosemide is a loop diuretic that causes potassium
wasting. Hypokalemia increases risk of digoxin toxicity and
arrhythmias.
,4. A client with hypertension is prescribed lisinopril
(Prinivil). Which finding requires immediate reporting?
A. Dry cough
B. Angioedema (swelling of lips/tongue)
C. Dizziness
D. Fatigue

baseline test is essential?
A. Pulmonary function tests
