Explanation

The American Heart Association (AHA) guidelines for high-quality CPR recommend that rescuers performing chest compressions should switch positions every 2 minutes.
Switching every 5 minutes, as stated in the option, is incorrect and would lead to significant rescuer fatigue.
Fatigue results in decreased quality of compressions, specifically inadequate rate and depth, which compromises blood flow to vital organs.
The 2-minute rotation is typically coordinated with the rhythm check to minimize pauses in compressions.

Option A: This is a correct and essential metric of high-quality CPR. Chest compression fraction (CCF) is the proportion of time that compressions are being performed. A high CCF (target greater than 80%) is associated with better outcomes.
Option B: This is the correct compression rate recommended by AHA guidelines for adults, children, and infants. This rate maximizes cardiac output without being too fast to allow for adequate heart filling.
Option C: This is a correct guideline. Excessive ventilation (hyperventilation) is harmful as it increases pressure inside the chest, which reduces venous return to the heart, decreases cardiac output, and lowers survival chances.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Components of High-Quality Cardiopulmonary Resuscitation (CPR) as background academic context rather than a clinical decision trigger.
Adhering to all metrics of high-quality CPR is a direct responsibility of the nursing staff and resuscitation team, as it significantly impacts patient survival and neurological outcome.
During a code, the team leader or a designated monitor should provide real-time feedback on CPR quality (e.g., 'Push faster,' 'Push deeper,' 'Allow full recoil') and enforce the 2-minute switch.
What if? If a defibrillator with CPR feedback technology is used, it will provide audio and visual prompts for rate, depth, and recoil. If it detects rescuer fatigue before 2 minutes, the team leader should direct an immediate switch to maintain quality.

How to Approach the Question

First, identify the core subject of the question, which is 'high-quality CPR'.
Next, recognize the negative framing of the question, which asks for the component that is 'NOT' included.
This structure implies that three of the options are correct principles of high-quality CPR, and one is incorrect.
Systematically review each option by recalling the standard CPR guidelines (AHA).
Evaluate Option A (Compression fraction >80%), Option B (Rate 100-120/min), and Option C (No excessive ventilation). All are established, correct components.
Evaluate Option D (Rescuer change every 5 minutes). Recall that to prevent fatigue, the standard is to switch compressors every 2 minutes. This statement is incorrect.
