CCA Adhesives & Retention Systems 2

Question 1

What is the recommended skin preparation sequence BEFORE applying medical-grade adhesive for a facial prosthesis?

Accepted Answer

Cleanse with soap and water, rinse thoroughly, then degrease with isopropyl alcohol

Answer

Apply moisturizing lotion to reduce friction during placement

Answer

Apply petroleum jelly to protect sensitive skin areas first

Answer

Exfoliate vigorously with an abrasive scrub immediately before application

Question 2

A patient reports that their facial prosthesis repeatedly detaches within 2–3 hours of application despite using adequate adhesive volume. The MOST likely cause is:

Accepted Answer

Insufficient degreasing of the skin prior to adhesive application

Answer

The prosthesis is too heavy for adhesive retention

Answer

The adhesive brand has expired

Answer

The prosthesis color does not match the patient's skin tone

Question 3

How should a patient with radiation-damaged peri-orbital skin be counseled regarding adhesive retention for an orbital prosthesis?

Accepted Answer

Use the gentlest compatible adhesive with careful daily monitoring for skin breakdown

Answer

Use stronger, more aggressive adhesives to compensate for reduced skin integrity

Answer

Rely solely on spectacle frame retention and avoid all adhesive contact

Answer

Defer prosthetic wear entirely until radiation effects fully resolve

Question 4

What is the recommended frequency for removing and reapplying an adhesive-retained facial prosthesis to maintain skin health?

Accepted Answer

Daily, or as clinically directed

Answer

Weekly

Answer

Every 2–3 days

Answer

Only when the prosthesis begins to detach spontaneously

Question 5

When fitting a patient for an adhesive-retained nasal prosthesis, which competency is MOST essential to verify before discharge?

Accepted Answer

The patient can independently apply and remove the prosthesis and perform daily skin care

Answer

The patient can describe the adhesive chemical composition

Answer

A caregiver is available to apply the prosthesis each morning

Answer

The prosthesis can be worn continuously for one week before first removal

Question 6

Which type of retention aid is commonly applied along the thin peripheral edges of a silicone facial prosthesis to improve the peripheral seal and feathered edge adherence?

Accepted Answer

Medical-grade adhesive applied to the prosthesis edge and adjacent skin margin

Answer

Zinc oxide paste

Answer

Petroleum-based sealant

Answer

Liquid latex blended into the prosthesis margin

Question 7

A patient reports skin redness and mild blistering at the prosthesis margin after one week of wear. The FIRST clinical step is to:

Accepted Answer

Investigate potential adhesive allergy, technique errors, and skin condition before modifying the protocol

Answer

Switch to a stronger adhesive to reduce application frequency

Answer

Discontinue adhesive use permanently and refer to plastic surgery

Answer

Apply additional adhesive over the irritated area to protect it
