For a patient who has a muscle sprain, localized hemorrhage, or hematoma, which wound care product helps prevent edema formation, control bleeding, and anesthetize the body part?

Q

Which of the following is an indication for a binder to be placed around a surgical patient with a new abdominal wound?

Reduction of stress on the abdominal incision

88
Q

When is an application of a warm compress indicated? (Select all that apply.)

To relieve edema;

To improve blood flow to an injured part

89
Q

What is the removal of devitalized tissue from a wound called?

A

Debridement

90
Q

Name the three important dimensions to consistently measure to determine wound healing.

A

Width, Length, and Depth

91
Q

What does the Braden Scale evaluate?

A

skin integrity risk

92
Q

that the tissue over the sacrum is dark, hard, and adherent to the wound edge. What is the correct stage for this patient’s pressure ulcer?

A

Unstageable

93
Q

Name one intervention and the rationalization to use that intervention to reduce the likelihood of a shear injury to a patient.

A

transfer device can pick up a patient and prevent his or her skin from sticking to the bed sheet as he is repositioned. A second intervention would be to position the patient with the head of the bed to be elevated at 30 degrees, which prevents him or her from sliding. A third intervention would be to educate the patient and his or her caregiver on the importance of not sliding on the sheets when repositioning.
