A client who has been transported to the emergency room after a motor vehicle accident is experiencing asystole. Management of asystole focuses on:

High-quality CPR with minimal interruptions

Cessation at resuscitation attempts after 2 minutes

Administration of Narcan until an electrical rhythm is obtained

Continuous defibrillation until an electrical rhythm is obtained

Answer and Explanation

The Correct Answer is A

A. High-quality CPR with minimal interruptions is the cornerstone of asystole management. Asystole is a non-shockable rhythm, so maintaining perfusion through effective chest compressions and administering appropriate medications (like epinephrine) is essential.
B. Cessation of resuscitation efforts after only 2 minutes is inappropriate; the decision to stop should be based on the clinical scenario and response to interventions over time.
C. Narcan (naloxone) is used for opioid overdose, not for treating asystole unless there is a suspected opioid-related cause—and it does not directly restore electrical cardiac rhythm.
D. Defibrillation is not indicated in asystole, as it is a non-shockable rhythm. Continuous defibrillation is ineffective and inappropriate.

Correct Answer is B

Explanation

A. Ongoing cardiac care is still necessary after valvuloplasty to monitor valve function and complications.
B. Mechanical valve replacements require lifelong anticoagulant therapy to prevent thromboembolism, which is an important consideration when comparing with valvuloplasty.
C. Biologic valves do not require immunosuppressive drugs because they are derived from animal tissue.
D. Mechanical valves are durable and often last longer than 5 years, usually 10-20 years or more before replacement might be needed.

A. Heart rate 160/min B. Blood pressure 115/68 mmHg C. Hypokalemia D. Mottled skin

Correct Answer is B

Explanation

A. A heart rate of 160/min is more indicative of the progressive stage of shock, where compensation begins to fail.
B. Blood pressure 115/68 mmHg is within normal limits and reflects the compensatory stage, where the body maintains perfusion through mechanisms like increased heart rate and vasoconstriction.
C. Hypokalemia is not a typical finding in the compensatory stage; electrolyte shifts are more pronounced in later stages.
D. Mottled skin is a sign of poor perfusion, typically seen in the progressive or irreversible stages of shock.
