Correct Answer is C

Explanation

A. Magnesium sulfate B. Digoxin C. Atropine sulfate D. Diltiazem

Correct Answer is C

Explanation

This is because the client is experiencing bradycardia, which is a slow heart rate of less than 60/min. Bradycardia can cause decreased cardiac output, which can lead to symptoms such as tremors, fainting, dizziness, chest pain, shortness of breath, and hypotension. Some causes of bradycardia are sinus node dysfunction, atrioventricular block, medication side effects, hypothyroidism, hypothermia, and increased vagal tone.

The nurse should anticipate administering atropine sulfate, which is an anticholinergic drug that blocks the action of the vagus nerve on the heart and increases the heart rate and conduction. Atropine sulfate is the first-line drug for symptomatic bradycardia and can be given intravenously or intramuscularly. The nurse should monitor the client's vital signs, cardiac rhythm, and response to the medication. The nurse should also prepare for other interventions, such as transcutaneous pacing or permanent pacemaker insertion, if atropine sulfate is ineffective or contraindicated.
