The New-Grad PTA and the Complex Neuro Patient
Marcus is a newly licensed PTA in his third week of practice at an outpatient clinic in Little Rock. His supervising PT, Dr. Alvarez, has been called to an emergency and leaves for the day. Before leaving, Dr. Alvarez says, 'Just follow the plan of care on Mr. H, you've got this.' Mr. H is a 68-year-old man 10 days post-stroke with left-sided hemiparesis, new-onset atrial fibrillation, and a recent episode of dizziness when standing. The plan of care calls for gait training with a rolling walker and progressive resistance exercise. During the session, Mr. H reports feeling 'lightheaded and fluttery' in his chest. His blood pressure is 158/94, heart rate 118 and irregular. Marcus is the only clinician on the floor; the front-desk coordinator is the only other person present.
1. May Marcus continue the gait training and resistance exercise as written in the plan of care? Identify the clinical and legal issues and the correct course of action.

No - Marcus should not continue the session as planned.
Two overlapping issues:
Clinical red flag. New lightheadedness, an irregular tachycardia of 118, and known atrial fibrillation in a patient 10 days post-stroke are warning signs that require stopping activity and escalating. Continuing gait training with a patient who is symptomatic and has orthostatic symptoms is unsafe regardless of what the plan of care says.
Supervision and scope. A PTA practices under the direction and supervision of a PT and may not independently alter the plan of care, evaluate, or make autonomous clinical decisions outside the established plan. The PT's casual 'you've got this' does not convert into authority to manage a new medical event. The PTA's obligations are to stop, ensure safety (assist to seated position, monitor), and communicate with the supervising PT or a covering PT.
Correct course: stop the activity, position the patient safely, take vitals, and follow the clinic's emergency protocol - activating EMS if symptoms persist or worsen. Document the event objectively and notify Dr. Alvarez or the designated covering PT before any further treatment. The PT of record retains responsibility for reassessing and revising the plan of care.
2. The clinic's policy states that when the supervising PT is off-site, the PTA may treat 'routine' patients independently. Does that policy protect Marcus here?
Read the worked answer
No. A facility policy cannot expand a PTA's legal scope or override the supervisory requirements of the practice act. Policy can be stricter than the law but not looser.
Even setting aside the acute event, Mr. H is not a routine patient: recent stroke, cardiac comorbidity, and a history of orthostatic dizziness make him a patient whose care requires PT-level judgment. The relevant question is not what the front desk or a policy binder permits, but whether the PTA is acting within the delegated plan of care and with the required level of supervision. When a patient's condition changes, the PTA's duty is to stop and escalate, not to rely on a generic off-site policy.
If Marcus is ever unsure whether a patient falls within his authorized scope under a given supervision arrangement, the safe and defensible answer is to seek PT direction before treating.
