A nurse is providing BLS training to a group of individuals. During the training, a participant asks about the compression-to-ventilation ratio for adult CPR. What is the nurse's best response?
"For adult CPR, the compression-to-ventilation ratio is 5:1."
"The compression-to-ventilation ratio for adult CPR is 30:2."
"Adult CPR requires continuous compressions without providing any ventilations."
"The compression-to-ventilation ratio for adult CPR is 10:1."
The Correct Answer is B
A) Incorrect. The compression-to-ventilation ratio of 5:1 is not the current guideline for adult CPR. The correct ratio involves more frequent compressions.
B) Correct. The recommended compression-to-ventilation ratio for adult CPR is 30:2. This means 30 chest compressions followed by 2 rescue breaths.
C) Incorrect. Continuous compressions without providing ventilations can lead to inadequate oxygenation, which is essential for the survival of the individual.
D) Incorrect. The compression-to-ventilation ratio of 10:1 is not the current guideline for adult CPR. The correct ratio involves more frequent compressions and periodic rescue breaths.

Correct Answer is B
Explanation
A) Incorrect. The correct compression rate for BLS chest compressions is higher than 80 compressions per minute. This rate may not be sufficient to maintain adequate circulation.
B) Correct. The correct compression rate for BLS chest compressions in an unresponsive client without a pulse is 100-120 compressions per minute. This rate ensures adequate blood flow to vital organs during CPR.
C) Incorrect. 30 compressions per minute is too low for effective chest compressions during BLS. The recommended rate is higher, as mentioned in option B.
D) Incorrect. 60 compressions per minute is lower than the recommended rate for BLS chest compressions. The correct rate, as mentioned in option B, is 100-120 compressions per minute.
Correct Answer is D
Explanation
A) Incorrect. Placing the hands on the lower half of the breastbone is not the correct hand placement for adult CPR chest compressions. The hands should be positioned higher on the sternum.
B) Incorrect. Placing one hand on the chest and the other on the forehead is not the correct hand placement for adult CPR. Both hands should be positioned on the sternum.
C) Incorrect. Placing the hands on the upper abdomen is not the correct hand placement for adult CPR. The hands should be positioned on the sternum.
D) Correct. The correct hand placement for adult CPR chest compressions is to center the hands on the sternum, between the nipples. Proper hand placement ensures effective compression depth and allows for adequate blood flow during CPR.
