A PTA is instructed to provide electrical stimulation to a patient with a venous stasis ulcer on the right lower extremity. What is the correct type of electrical stimulation to promote wound healing?

A physical therapist receives an order from the physician to treat a patient using iontophoresis. The order indicates that the purpose of the treatment is to attempt to dissolve a calcium deposit in the area of the Achilles tendon. The physical therapist then allows a PTA to help treat the patient. When preparing the patient for treatment, the assistant connects the medicated electrode to the negative pole. Which of the following medications is the assistant most likely preparing to administer?

A patient is being treated with iontophoresis, driving dexamethasone, for inflammation around the lateral epicondyle of the left elbow. The PTA is careful when setting the parameters and with cleaning the site of electrode application to prevent a possible blister. This possibility is not as strong with some forms of electrical stimulation, but because iontophoresis uses this form of electrical current, precautions must be taken to ensure that the patient does not receive a mild burn or blister during treatment :

A PTA prepares to administer iontophoresis over the anterior surface of a patient’s knee. The PTA would like to keep the current density low in order to avoid skin irritation. Which of the listed parameters would BEST accomplish the stated objective?

A PTA would like to minimize the likelihood of a burn while using iontophoresis. Which action would be the MOST consistent with the PTA’s objective?

A PTA treats a patient diagnosed with lateral epicondylitis using iontophoresis. The PTA uses dexamethasone with a current intensity of 3 mA for 20 minutes. How often during the treatment session should the PTA check the patient’s skin?
