Which of the under mentioned chest compression relate to 2015 CPR guidelines?

Appeared in: SCTIMST Staff Nurse - 2016

Explanation

The 2015 American Heart Association (AHA) guidelines for CPR specify a target chest compression rate of 100 to 120 per minute.
This rate is considered optimal for providing adequate blood flow (perfusion) to the brain and heart during cardiac arrest.
The upper limit of 120/min was set because studies showed that excessively fast rates can reduce blood flow due to incomplete chest recoil, which is necessary for the heart to refill.

Option A: The upper limit of 125 compressions per minute is too fast and exceeds the maximum rate of 120 recommended by the 2015 AHA guidelines.
Option B: This range is incorrect because it excludes the acceptable lower range of 100-109 compressions/min and exceeds the maximum recommended rate of 120/min.
Option C: This represents only the minimum acceptable rate. The guidelines specify a target range (100-120/min) to guide performance, not a single absolute number.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain CPR chest compression rate (2015 AHA Guidelines) as background academic context rather than a clinical decision trigger.
Performing chest compressions at the correct rate of 100-120/min is a critical nursing skill that directly impacts survival and neurological outcomes in cardiac arrest.
Nurses must be able to initiate and maintain high-quality CPR, including guiding other rescuers to maintain the correct pace, often using a metronome or feedback device.
What if? If a rescuer performs compressions at a rate of 140/min, the action would be to instruct them to slow down. Excessively fast rates do not allow for full chest recoil, which impairs venous return and reduces the heart's ability to fill with blood, making CPR less effective.

How to Approach the Question

First, identify the core of the question, which is asking for a specific numerical value from a clinical guideline: the chest compression rate from the '2015 CPR guidelines'.
This is a factual recall question. Access your memory of CPR training and standards.
Evaluate each option against the known standard. The 2015 AHA update established a clear range.
Eliminate options that are outside this range. Option A and B include rates above 120/min, making them incorrect.
Compare the remaining options. Option C gives a single value (100/min), while Option D gives the full recommended range (100-120/min).
Select the option that most completely and accurately represents the guideline. The guideline is a range, not a single minimum number, so 100-120/min is the best answer.
