Final answer:
If a patient has no pulse during an assessment, the next step is to initiate chest compressions.
Step-by-step explanation:
If, during the assessment of an unresponsive medical patient, you find that the patient has no pulse, the next step is to initiate chest compressions. Chest compressions are a crucial part of cardiopulmonary resuscitation (CPR) and help circulate blood to vital organs like the brain. The American Heart Association recommends compressing the chest at least 5 cm deep and at a rate of 100 compressions per minute to provide effective CPR.
