ABSTRACT
MECHANICAL MECHANISMS 2. Which one of the following is thought to be largely responsible for wound edges
drawing closer together during NPWT? A. Microstrain B. Macrostrain C. Nanostrain
D. Equilibration of stresses E. Strain neutralization
CONTACT LAYERS IN NEGATIVE PRESSURE WOUND THERAPY 3. Different foam dressings can be used with negative pressure dressing systems. What
is the main theoretical clinical benefit of using foam with a larger pore size? A. Reduced infection B. Increased tissue production C. Increased fluid removal
D. Reduced pain E. Lower financial cost
4. Which one of the following base layers has the largest volume of evidence supporting its use in NPWT? A. Polyvinyl foam B. Polypropylene foam C. Polyurethane foam
D. Silver-coated sponge E. Honeycomb gauze
5. A number of different base layers can be used in conjunction with NPWT and selection can affect outcome. Which one of the following is correct regarding base layer selection? A. Silver-coated sponge dressings are beneficial to decrease wound odor. B. PVA white foam should be used when rapid granulation is required. C. Use of gauze as a base layer tends to increase pain compared with foam dressings. D. Healing times are reduced when using foam rather than gauze. E. NPWT avoids the need for a nonadherent base layer on skin grafts.
