Final answer:
After a myocardial infarction, the most suitable referral is cardiac rehab, as it specializes in improving heart health through exercise, education, and lifestyle changes specific to heart recovery processes.
Step-by-step explanation:
The most appropriate referral for a client who has been admitted to the telemetry unit from ICU after having a myocardial infarction (MI) is cardiac rehab. Cardiac rehabilitation is a critical component of recovery and focuses on exercise, health education, and lifestyle changes to improve heart health and reduce the risk of future heart problems. While physical therapists are experts in body mechanics and can assist with muscle or joint injuries, which may be part of the recovery process, cardiac rehab is a specialized program tailored specifically for patients recovering from heart-related issues including MIs.
