A nurse is caring for a client who reports heart palpitations that come and go. An ECG confirms the client is experiencing episodes of ventricular tachycardia (VT). The client is stable. The nurse should anticipate the need for taking which of the following actions?

Elective cardioversion

CPR

Radiofrequency catheter ablation

Defibrillation

Answer and Explanation

The Correct Answer is A

A.   Elective cardioversion is a procedure used to restore a normal heart rhythm by delivering a controlled electrical shock to the heart. It is generally used for patients with stable atrial or ventricular arrhythmias who do not respond to medication. In the case of stable VT, elective cardioversion might be considered if the arrhythmia is causing symptoms or if the patient’s condition changes
B.   CPR is an emergency procedure used when a person’s heart has stopped beating (cardiac arrest) or when they are not breathing. It is not indicated for a stable VT because the patient is still stable and conscious, and CPR is not used for arrhythmias like VT in a stable patient.
C.   Radiofrequency catheter ablation is a procedure used to destroy abnormal electrical pathways in the heart that cause arrhythmias. This is often used as a treatment for recurrent or persistent VT, especially if medication or cardioversion fails to manage the condition effectively. For a stable patient with VT, this treatment might be considered in the long-term management plan rather than as an immediate intervention.
D.   Defibrillation is the use of an electrical shock to the heart to restore a normal rhythm in cases of life- threatening arrhythmias such as ventricular fibrillation or pulseless VT. It is not used for stable VT because the patient still has a pulse and is not in immediate danger of cardiac arrest

Correct Answer is B

Explanation

A. While there are strict inclusion and exclusion criteria for alteplase administration, this statement is overly broad. There are certain situations where anticoagulant or antiplatelet therapy can be managed to allow for alteplase use.
B. Alteplase is administered as a bolus over 1 minute, followed by an infusion over 60 minutes.
C. While time is critical in stroke treatment, the recommended window for alteplase administration is typically within 3-4.5 hours of symptom onset.
D. The maximum dose of alteplase is actually 0.9 mg/kg, up to a maximum of 90 mg.

Correct Answer is ["0.5"]

Explanation

Volume = Dose / Concentration. The dose required is 35 mg, and the concentration available is 75 mg/mL.

35 mg divided by 75 mg/mL, which equals 0.4667 mL. When rounded to the nearest tenth, this is 0.5 mL.

Therefore, the nurse should administer 0.5 mL of meperidine injection per dose.
