A client is prescribed 40 mg of furosemide orally. The furosemide tablets on hand are 20 mg tablets. How many tablets will the nurse administer? (Type only the number in the box.)

 

A. Give 2 rescue breaths: In cardiac arrest due to V.Fib, the priority is circulation. High-quality chest compressions are initiated immediately to maintain perfusion until defibrillation can be performed. Rescue breaths are not the first step.

B. Start chest compressions: V.Fib is a lethal rhythm with no effective cardiac output. Immediate chest compressions are essential to circulate oxygenated blood to vital organs while preparing for defibrillation. This is the first action in Basic Life Support (BLS) and Advanced Cardiac Life Support (ACLS).

C. Assess the client: While assessment is important, in the context of a witnessed rhythm strip showing V.Fib and an alarm, the nurse should assume cardiac arrest and act immediately. Delaying compressions to reassess wastes critical seconds.

D. Call a code blue/call 911: This is necessary, but it comes after starting chest compressions. The priority is to begin CPR without delay, then activate emergency response and prepare for defibrillation.

A. Assessing the legs and feet for peripheral edema: While edema is an important indicator of heart failure, it does not provide real-time information about the electrical activity of the heart. Edema is a chronic sign of volume overload rather than an acute indicator of dysrhythmia severity. It is not the most critical assessment prior to antiarrhythmic administration.

B. Checking the results of the most recent ECG: An ECG provides a snapshot of previous electrical activity but may not reflect the patient's current hemodynamic status. The nurse must assess the patient's actual physiological presentation at the moment the medication is being given. Bedside assessment is superior to relying solely on historical diagnostic data.

C. Listening to the apical pulse for a full minute: Antiarrhythmic medications can significantly alter heart rate and rhythm, potentially causing profound bradycardia or new conduction blocks. Assessing the apical pulse for 60 seconds provides the most accurate baseline of the heart's current rate and regularity. This is a mandatory safety step to ensure the patient can tolerate the drug.

D. Taking the blood pressure in both arms: While blood pressure is a vital sign, it is a secondary manifestation of the heart's pumping efficiency rather than a direct measure of the rhythm. A single arm reading is usually sufficient unless a specific vascular discrepancy is suspected. The primary concern with dysrhythmia medications is the heart rate itself.
