A client is given amiodarone (Cordarone) in the emergency department for a dysrhythmia. Which of the following indicates the drug is having the desired effect?
- A. The ventricular rate is increasing.
- B. The absent pulse is now palpable.
- C. The number of premature ventricular contractions is decreasing.
- D. The fine ventricular fibrillation changes to coarse ventricular fibrillation.
Correct Answer: C
Rationale: Amiodarone treats ventricular arrhythmias. A decrease in PVCs indicates the drug is stabilizing the cardiac rhythm, its desired effect.

Which of the following positions would be appropriate for a client with severe ascites?
- A. Fowler's.
- B. Side-lying.
- C. Reverse Trendelenburg.
- D. Sims.
Correct Answer: A
Rationale: Fowler's position (A) elevates the head, reducing diaphragm pressure from ascites and aiding breathing. Side-lying (B), Reverse Trendelenburg (C), and Sims (D) are less effective.
Which of the following health promotion activities should the nurse include in the discharge teaching plan for a client with asthma?
- A. Incorporate physical exercise as tolerated into the daily routine.
- B. Monitor peak flow numbers after meals and at bedtime.
- C. Eliminate stressors in the work and home environment.
- D. Use sedatives to ensure uninterrupted sleep at night.
Correct Answer: A
Rationale: Regular exercise, as tolerated, improves lung function and overall health in asthma. Peak flow monitoring is typically done morning and evening. Eliminating all stressors is unrealistic. Sedatives may depress respiration and are not recommended.
A client with Buerger's disease has established a goal to stop smoking. Which medication would be the most helpful in attaining this goal?
- A. Zyban (Bupropion)
- B. Nicotine (Nicotrol)
- C. Nitroglycerin (Tridil)
- D. Ibuprofen (Advil)
Correct Answer: A
Rationale: Zyban (bupropion) is an antidepressant that reduces nicotine cravings and withdrawal symptoms, making it effective for smoking cessation in Buerger's disease. Nicotine replacement (Nicotrol) may help but continues nicotine exposure, nitroglycerin is for angina, and ibuprofen is irrelevant.
A client weighs 300 lb (136 kg) and has a history of deep vein thrombosis and thrombophlebitis. When reviewing a teaching plan with this client, the nurse knows that the client has understood the nurse's instructions when he states he will:
- A. Avoid exercise
- B. Lose weight
- C. Perform leg lifts every 4 hours
- D. Wear support hose, using rubber bands to hold the stockings up
Correct Answer: B
Rationale: Weight loss reduces pressure on veins and improves circulation, critical for managing DVT and thrombophlebitis in an obese client. Avoiding exercise increases stasis, leg lifts are insufficient alone, and rubber bands can cause constriction, negating support hose benefits.
The client is scheduled to have a kidney, ureter, and bladder (KUB) radiograph. To prepare the client for this procedure, the nurse should explain to the client that:
- A. Fluid and food will be withheld the morning of the examination.
- B. A tranquilizer will be given before the examination.
- C. An enema will be given before the examination.
- D. No special preparation is required for the examination.
Correct Answer: D
Rationale: A KUB radiograph requires no special preparation, as it is a non-invasive imaging test to locate renal calculi.
