Explanation

The recommended rate for chest compressions in adult CPR is 100 to 120 per minute, as per the latest American Heart Association (AHA) guidelines.
This rate provides an essential balance between pushing blood out of the heart to circulate to vital organs and allowing enough time for the heart to refill with blood between compressions (chest recoil).
Maintaining this rate is a key component of high-quality CPR, which is directly linked to improved patient survival outcomes after cardiac arrest.

Option B: A rate of 70-90 compressions per minute is too slow to generate adequate blood flow and pressure, resulting in insufficient oxygen delivery to the brain and other vital organs.
Option C: A rate of 140-160 compressions per minute is too fast. It does not allow for complete chest recoil, which is necessary for the heart to refill with blood, thereby reducing the effectiveness of each compression.
Option D: Similar to the 140-160 range, a rate of 130-150 compressions per minute is excessively fast and impairs cardiac filling between compressions, leading to poor cardiac output and reduced perfusion.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Cardiopulmonary Resuscitation (CPR) Guidelines as background academic context rather than a clinical decision trigger.
Performing high-quality CPR at the correct rate and depth is a fundamental and life-saving skill for nurses that directly impacts patient survival after cardiac arrest.
In a 'Code Blue' situation, nurses are often the first responders. Their role includes not only initiating CPR but also leading the team to ensure guidelines are followed, such as switching compressors every 2 minutes to prevent fatigue.
What if? If the patient is a child (1 year to puberty), the compression rate remains the same (100-120/min), but the compression-to-ventilation ratio changes to 15:2 if two rescuers are present.

How to Approach the Question

This is a factual recall question based on established clinical guidelines for emergency care.
First, identify the key terms in the question: 'CPR', 'adult', and 'rate of chest compressions'.
Next, recall the standard guidelines from the American Heart Association (AHA) for Basic Life Support (BLS).
The recommended rate is a specific range. Evaluate the given options against this standard.
Eliminate options that are clearly too slow (less than 100) or too fast (greater than 120).
Select the option that precisely matches the current recommended range of 100-120 compressions per minute.
