120 Questions, Correct ANSWERS
GRADED A+
What is the difference between an active and reactive support surfaces/ - --ANS---active support
surface is a powered mattress or overlay that changes it's load- distribution with or without
applied load; pressure is redistributed across the body by inflating and deflating the cells of
alternating zones. conversely a reactive support surface moves or changes load-distribution
properties only in response to applied load, such as the patient's body.
When are active support surfaces appropriate? - --ANS---when manual frequent repositioning is
not possible
when are reactive support surfaces appropriate? - --ANS---for pressure ulcer prevention

what is a benefit in low air loss feature and when is it contraindicated? - --ANS---low air loss
assists in managing mositure. It is contraindicated in patients with unstable spine and it puts
patients at risk for entrapment
when is an air fluidized feature integrated in bed systems appropriate? - --ANS---for patients
with multiple stage III or Iv pressure ulcers, burns, myocutaneous skin flap
for what kind of patients are traditional air-fluidized bed not recommended? - --ANS---
pulmonary diseases or unstable spine patients
what are some general guidelines for caring for patients on a support surface? - --ANS---support
surfaces alone doe snot prevent or heal PUs, fuctions best with minimal linens and pads under
patients, must be able to assume variety of positions to prevent bottoming out, patients should be
turned regardless of support surfaces, patients who sit with a risk for PU should have a sitting
plan- duration, position, and posture
what type of patient is a lateral rotation feature in a supportive surface beneficial? - --ANS---for
patients with acute respiratory conditions- requiring pulmonary hygience
what are the 3 essential physical properties for normal venous function? - --ANS---competent
valves, venous wall, and calf muscle pump
, 3|Page
what are the classical characteristic traits seen in venous ulcers? - --ANS---shallow, irregular
wound eges, with moderate to heavy exudate, dark red or "ruddy" wound base or thin layer of
yellow slough, macerated periwound, crusting, scaling and /or hemosiderin staining
Define hemosiderin staining? - --ANS---leakage of RBCs which have been broken down appears
as a purple to brown staining
Define lipodermatosclerosis? - --ANS---hardening of soft tissue where hemosiderin staining
evolves into lipodermatosclerosis- found on gaiter and sock areas and has appearance of inverted
champagne bottle
Define atrophie blanche? - --ANS---smooth, white plaques of think speckled atrophic tissue with
tortous vessels on ankle or foot with hemosiderin pigmented border
Define venous dermatitis? - --ANS---characterized by scaling, crusting, weeping, erythema,
erosions, and intense itching.
Differentiate dermatitis from cellulitis? - --ANS---In cellulitis, patients will often exhibit pain,
fever, tenderness, one or few bullae, no relevent history, no crusting, blood cxs usually negative,
no lesions anywhere else other than localized area, and high WBC count
What factors impede healing in venous ulcers? - --ANS---DM, tobacco, malnutrition, umplanned
weight loss, and meds (corticosteroids)
