The nurse is functioning in the role of medication nurse during a code. Which should the nurse implement when administering amiodarone for ventricular tachycardia?
- A. Mix the medication in 100 mL of fluid and administer rapidly.
- B. Push the amiodarone directly into the nearest IV port and raise the arm.
- C. Question the physician’s order because it is not ACLS recommended.
- D. Administer via an IV pump based on mg/kg/min.
Correct Answer: D
Rationale: Amiodarone for VT is administered via IV pump (D) per ACLS (e.g., 150 mg over 10 min). Rapid infusion (A) risks hypotension, direct push (B) is incorrect, and questioning (C) is unnecessary.

Which finding would strongly indicate that the cardioversion procedure has been successful?
- A. The client regains consciousness immediately.
- B. Normal sinus cardiac rhythm is restored.
- C. The physical examination of the patient is a second.
- D. The pulse pressure is approximately 40 mm Hg.
Correct Answer: B
Rationale: Restoration of normal sinus rhythm is the primary goal of cardioversion.
The telemetry nurse notes a peaked T wave for the client diagnosed with congestive heart failure. Which laboratory data should the nurse assess?
- A. CK-MB.
- B. Troponin.
- C. BNP.
- D. Potassium.
Correct Answer: D
Rationale: Peaked T waves indicate hyperkalemia; assessing potassium (D) is critical in CHF patients on diuretics. CK-MB (A) and troponin (B) are for MI, BNP (C) for heart failure severity.
After hearing the nurse's instructions about activity restrictions and the potentially dangerous consequences of certain activities, the client correctly states the importance for avoiding which of the following?
- A. Carrying groceries from the car
- B. Straining during a bowel movement
- C. Bathing in warm water
- D. Having sexual intercourse
Correct Answer: B
Rationale: Straining during a bowel movement increases intrathoracic pressure, raising cardiac workload and MI risk.
The client is exhibiting ventricular tachycardia. Which intervention should the nurse implement first?
- A. Administer amiodarone, an antidysrhythmic, IVP.
- B. Prepare to defibrillate the client.
- C. Assess the client's apical pulse and blood pressure.
- D. Start basic cardiopulmonary resuscitation.
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.
The nurse knows that the client understands the physician's explanation of the PTCA procedure when the client makes which statement?
- A. A balloon-tipped catheter will be inserted into my coronary artery.
- B. A Teflon graft will be used to replace an area of my artery.
- C. A section of my leg vein will be grafted around a narrowed coronary artery.
- D. A battery-operated pacemaker will be implanted to maintain my heart rate.
Correct Answer: A
Rationale: PTCA involves inflating a balloon-tipped catheter to open a narrowed coronary artery, improving blood flow.
