Davis Chapter 18 Heat Therapy

Question 1

HEAT THERAPY:

The local application of heat to an area of the body results in

Answer 1

vasodilation

Question 2

Heat Therapy for an increased flow of oxygenated and nutrient-rich blood to the

Answer 2

tissues

Question 3

The pores in the capillary walls become more permeable during

Answer 3

Heat therapy

Question 4

When the capillary walls become permeable during heat therapy this allows

Answer 4

increased passage of plasma, oxygen-carrying red blood cells, nutrients, and white blood cells from the capillaries into the interstitial spaces

Question 5

Indications for Heat Therapy:

Answer 5

●Relaxation of muscle spasms
●Pain relief
●Support of the healing process
●Reduction of edema
●Elevation of body temperature in cases of hypothermia

Question 6

Use of heat therapy to the right lower abdomen during acute appendicitis could cause enough increased blood flow to the area to result in a ruptured appendix

Answer 6

Suspected appendicitis

Question 7

Applying heat to a bleeding wound or injury would dilate the vessels, increasing the bleeding

Answer 7

Bleeding wound or injury

Question 8

Heat increases edema, making joint mobility more difficult

Answer 8

Newly injured joints

Question 9

Extensive heat application can result in massive vasodilation to the superficial skin and subcutaneous layers, depriving the major organs, such as the brain, heart, lungs, and kidneys, of adequate blood supply, which can cause serious damage

Answer 9

Large areas of the body in certain cardiac patients

Question 14

Nursing Care During Heat Therapy: The nurse should

Answer 14

•Assess the patient’s skin for temperature, color, sensation, edema, and integrity

•Carefully check the temperature of the heating device before applying it to the patient

•Always reassess the skin after removal of the heat source to evaluate the patient’s response

Question 15

TRUE OR FALSE: If a patient is suspected of having appendicitis, heat therapy should be used?

Answer 15

False

Question 16

COLD THERAPY:

Application of cold to a site causes

Answer 16

vasoconstriction

Question 17

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

Answer 17

Cold therapy

Question 18

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

Answer 18

Systemic cold
