Final answer:
CPR may need to be interrupted if the patient regains spontaneous contraction or is declared dead by a healthcare professional.
Step-by-step explanation:
During the performance of cardiopulmonary resuscitation (CPR) on a client with a myocardial infarction (MI), there are certain situations in which CPR may need to be interrupted. One of the reasons for interrupting CPR is if the patient regains spontaneous contraction or is declared dead by an experienced healthcare professional. It is important to note that CPR should only be interrupted by a healthcare professional who is qualified to make that decision.
