PTAP 1240 MODALITIES FINAL EXAM
QUESTIONS WITH 100% CORRECT ANSWERS
Iontophoresis DOSAGE and TIME calculation? - ANSWER 40mA*m
Iontophoresis DRIVING FORCE or POLARITY? - ANSWER Based on
medicine: use SAME POLARITY on patch to REPEAL/PUSH meds.
ELECTROSTATIC REPULSION - ANSWER Using same polarity of
medicine on patch because equal polarities repeal and help push meds in
ADVERSE effects to Iontophoresis? - ANSWER -First Degree BURN
-SHOCK if machine turned off abruptly
-Transient ERYTHEMA at electrode site
-Metallic TASTE (at face)
-Alkaline/Acid Reaction
ADVERSE reactions to Iontophoresis? - ANSWER -Tingling
-Stinging (lower amplitude)
-Pulling Sensation
-Burning Sensation
-Pain
ACID Reaction to Iontophoresis - ANSWER -happens under (+) pad
-increase acidity promotes protein COAGULATION & tissue HARDENING
ALKALINE reaction to Iontophoresis - ANSWER -happens under (-) pad
-increase alkalinity promotes protein LIQUIFICATION and tissue
SOFTENING
Types of MEDICATION used in Iontophoresis? - ANSWER -Dexamethasone
phosphate (40 mA*m)
-Salicylate
-Lidocaine
, Dexamethasone phosphate ionic charge and purpose? - ANSWER (-) Anti-
inflammatory
Salicylate ionic charge and purpose? - ANSWER (-) Anti-inflammatory/Pain
Lidocaine ionic charge and purpose? - ANSWER (+) Anesthetic/Inflammation
Iontophoresis CONTRAINDICATIONS - ANSWER -Decreased SENSATION
-METAL IMPLANT
-Active BLEEDING
-Recent SCARS
-PACEMAKER
-ALLERGIES to meds/adhesive
COMMON meds for iontophoresis? - ANSWER Hydrocortisone,
Dexamethasone, Sodium Salicylate, Lidocaine
CORTICOSTEROID for iontophoresis? - ANSWER Indicated for
INFLAMMATION
Examples: HYDROCORTISONE and DEXAMETHASONE
SALICYLATES for iontophoresis? - ANSWER INFLAMMATION
SODIUM SALICYLATE
ANESTHETIC for iontophoresis? - ANSWER Used for PAIN and TRIGGER
points
Example: LIDOCAINE
DIFFERENCE between iontophoresis and phonophoresis? - ANSWER Both
are Trans-Dermal Delivery BUT...
Ionto = ELECTROREPULSIVE forces penetrate 8-10mm
Phono = Mechanical forces of US
