Q

COLD THERAPY:

Application of cold to a site causes

A

vasoconstriction

17
Q

During what therapy do the pores in the capillary walls become less permeable to fluid passing from the vessels to interstitial spaces

Result is decreased blood flow to the area

A

Cold therapy

18
Q

lowers the body temperature, slowing metabolism, decreasing tissue oxygen demand, and therefore decreasing the chance of ischemia

A

Systemic cold

19
Q

Indications for Cold Therapy:

A

●Prevention of edema
●Control or stoppage of bleeding
●Pain relief
●Numbing sensation
●Reduction of muscle spasm
●Reduction of fever

20
Q

Methods of Cold Application:

A

●Refreezable commercial cold packs
●Chemical cold packs
●Cold compresses
●Tepid baths

21
Q

Which of the following is an example of cold therapy?

A

Tepid baths

22
Q

are used mostly for reduction of body temperature when use of medication is undesirable or ineffective. Either a tub bath or pan of water for sponging the patient can be used.

A

Tepid (cool but not cold) baths

23
Q

Nursing Care During Cold Therapy

A

●Assessment of the skin is done before application of the cold therapy

●Leave cold packs in place no longer than 20 to 30 minutes

●The patient may complain of pain or a burning sensation, assess for pallor, and mottling

●The patient may require a blanket to cover the rest of the body

●Evaluate the effects of the cold therapy

24
