Extract:
Question 1 of 5
Which data would cause the nurse to question administering digoxin to a client diagnosed with congestive heart failure?
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.
Question 2 of 5
The nurse identifies the concept of perfusion for a client diagnosed with congestive heart failure. Which assessment data support this concept?
Correct Answer: B
Rationale: PND (
B) indicates fluid overload in CHF, supporting impaired perfusion. Large abdomen (
A) suggests ascites, glucosuria (
C) is diabetes-related, and MI (
D) is a cause, not a symptom.
Question 3 of 5
The client is exhibiting ventricular tachycardia. Which intervention should the nurse implement first?
Correct Answer: C
Rationale: Ventricular tachycardia requires assessing pulse/BP (
C) to determine if it’s pulseless (defibrillation,
B) or stable (amiodarone,
A). CPR (
D) is for pulseless states.
Question 4 of 5
Which prothrombin time value would be considered normal for a client who is receiving warfarin (Coumadin)?
Correct Answer: B
Rationale: For a client receiving warfarin, the prothrombin time should be 1.5 to 2 times the normal value (11 to 12.5 seconds). Twenty seconds falls within this therapeutic range. Twelve seconds is normal for someone not on warfarin. Sixty seconds is normal for a partial thromboplastin time (PTT) test, and 98 seconds would be therapeutic for heparin, not warfarin.
Question 5 of 5
An adult who is receiving heparin asks the nurse why it cannot be given by mouth. The nurse responds that heparin is given parenterally because:
Correct Answer: AUG
Rationale: Heparin is a protein and is destroyed by gastric secretions, requiring parenteral administration (intravenously or subcutaneously). It does not irritate the gastric or intestinal lining, and while parenteral administration allows faster therapeutic levels, the primary reason is its destruction in the stomach.
