- A. Atropine.
- B. Amiodarone.
- C. Adenosine.
- D. Dobutamine.
Correct Answer: C

A client is receiving digitalis. The nurse should instruct the client to report which of the following side effects?
- A. Nausea, vomiting, fatigue
- B. Rash, dyspnea, edema
- C. Polyuria, thirst, dry skin
Correct Answer: A
Rationale: Nausea, vomiting, fatigue. Side effects of digitalis toxicity include fatigue, nausea, vomiting, anorexia, and bradycardia. Digitalis inhibits the sodium potassium ATPase, which makes more calcium available for contractile proteins, resulting in increased cardiac output.
The client is showing ventricular ectopy, and the HCP orders amiodarone (Cordarone) intravenously. Which interventions should the nurse implement? Select all that apply.
- A. Monitor telemetry continuously.
- B. Assess the client's respiratory status.
- C. Evaluate the client's liver function studies.
- D. Confirm the original order with another nurse.
- E. Prepare to defibrillate the client at 200 joules.
Correct Answer: A,B,C
Rationale: Telemetry monitors dysrhythmias, respiratory status tracks amiodarone’s pulmonary toxicity risk, and liver studies monitor hepatotoxicity. Order confirmation is unnecessary, and defibrillation is unrelated.
The nurse administered an IV broad-spectrum antibiotic scheduled every six (6) hours to the client with a systemic infection at 0800. At 1000, the culture and sensitivity prompted the HCP to change the IV antibiotic. When transcribing the new antibiotic order, when would the initial dose be administered?
- A. Schedule the dose for 1400.
- B. Schedule the dose for the next day.
- C. Check with the HCP to determine when to start.
- D. Administer the dose within one (1) hour of the order.
Correct Answer: D
Rationale: New antibiotic orders for active infections require prompt administration (within 1 hour) to maintain therapeutic levels, per sepsis guidelines.
An adult is scheduled for a left cataract extraction. Homatropine and Cyclogyl eye drops are ordered. What is the expected action of these drops?
- A. Mydriasis
- B. Miotic effects
- C. Relaxation of eye muscles
- D. Prevention of infection
Correct Answer: A
Rationale: Homatropine and Cyclogyl are mydriatics, dilating the pupil to facilitate cataract surgery.
The nurse is administering the following 1800 medications. Which medication should the nurse question before administering?
- A. The sliding-scale insulin to the client who has just been released to have the evening meal.
- B. The antibiotic to the client who is one (1) day postoperative exploratory abdominal surgery.
- C. Metformin (Glucophage), a biguanide, to the client having a CT scan with contrast dye in the morning.
- D. Protonix, a proton pump inhibitor, to the client diagnosed with peptic ulcer disease.
Correct Answer: C
Rationale: Metformin must be held before contrast dye due to lactic acidosis risk if renal function is impaired; other medications are appropriate.
