Explanation

Current guidelines from bodies like the American Heart Association (AHA) recommend a universal chest compression rate of 100 to 120 per minute for adults, children, and infants.
A rate of 100 compressions per minute falls within this essential range, which is vital for maintaining adequate blood circulation (perfusion) to the brain, heart, and other organs during cardiac arrest.
The presence of one or two rescuers does not change the recommended rate of compressions. The primary advantage of a second rescuer is to minimize fatigue by switching the compressor role every 2 minutes and to provide a different compression-to-ventilation ratio (15:2) for children and infants.

Option B: While 120 compressions per minute is the upper limit of the recommended 100-120 range, rates faster than this can be detrimental. Exceeding 120 compressions/min may not allow enough time for the chest to fully recoil, which is necessary for the heart to refill with blood, thus reducing the effectiveness of CPR.
Option C: A rate of 130 compressions per minute is too fast and exceeds the current recommended guidelines. Such a high rate significantly impairs complete chest recoil, reducing blood flow to the heart and decreasing the overall effectiveness of CPR.
Option D: A rate of 80 compressions per minute is too slow and falls below the minimum recommended rate of 100 per minute. This slow rate is insufficient to generate the necessary blood pressure and circulation to keep vital organs alive.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Cardiopulmonary Resuscitation (CPR) chest compression rate as background academic context rather than a clinical decision trigger.
Mastering high-quality CPR, including the correct rate, is a fundamental, life-saving skill for every nurse. The quality of compressions directly impacts patient survival and neurological outcome.
In a two-rescuer scenario, clear communication and teamwork are critical. The team must switch the compressor role every 2 minutes (or 5 cycles) to prevent fatigue, as tired rescuers provide shallower and less effective compressions.
What if? If the patient is a newborn infant (neonate) requiring resuscitation immediately after birth, the protocol changes. The compression-to-ventilation ratio becomes 3:1, aiming for 90 compressions and 30 breaths per minute (120 total events), and the two-thumb encircling hands technique is preferred.

How to Approach the Question

First, identify the core parameter the question is asking for: the rate of chest compressions per minute in CPR.
Recall the standard guideline for compression rate from your Basic Life Support (BLS) training. The recommended range is 100-120 compressions per minute.
Evaluate the given options against this established range. Options for 80 and 130 are immediately incorrect as they fall outside the recommended parameters.
Consider the two remaining options: 100 and 120. Both fall within the correct range.
Recognize that 100 compressions/minute is the established minimum effective rate and a common standard. In an exam question where both the minimum and maximum of a range are provided as options, the minimum effective rate is a safe and correct choice.
Confirm your understanding that the number of rescuers does not change the compression rate itself, but rather the compression-to-breath ratio (in certain populations) and fatigue management.
