Chapter 18 : Applying Heat and Cold Therapies Questions
Question 1 of 5
Choose the correct answer(s). In some questions, more than one answer is correct. Select all that apply. Which of the following physiological changes will help an infected wound to heal?
Correct Answer: A,B,E,F
Rationale: Phagocytosis (
A) clears pathogens, increased blood flow (
B) and nutrients (E) support tissue repair, and increased cellular metabolism (F) aids healing. Vasoconstriction (
C) and decreased oxygen (
D) impair healing.
Question 2 of 5
Choose the correct answer(s). In some questions, more than one answer is correct. Select all that apply. Common uses for cold applications include
Correct Answer: C,D,E,F
Rationale: Cold therapy reduces pain (
C) by numbing nerves, promotes hemostasis (
D) by vasoconstriction, prevents swelling (E), and reduces edema (F). Hypothermia (
A) is a risk, not a use, and fever reduction (
B) is less common.
Question 3 of 5
Choose the correct answer(s). In some questions, more than one answer is correct. Select all that apply. The physiological effects of local heat application include the
Correct Answer: A,C,E,F
Rationale: Local heat application causes vasodilation, leading to dilation of veins (
A) and increased blood flow, which delivers more oxygen (E) and nutrients (F) to the area. It also relaxes muscle spasms (
C). Constriction of veins (
B) and decreased blood flow (
D) are incorrect as they oppose the effects of heat.
Question 4 of 5
Choose the correct answer(s). In some questions, more than one answer is correct. Select all that apply. Which of the following physiological changes make the elderly more susceptible to burns from heat applications?
Correct Answer: A,C,D
Rationale: Elderly individuals have thinner skin (
A), reduced tactile sensation (
C), and potential cognitive changes (
D) that impair their ability to detect excessive heat, increasing burn risk. More porous bones (
B) are unrelated to burn susceptibility.
Question 5 of 5
Choose the correct answer(s). In some questions, more than one answer is correct. Select all that apply. Patient teaching regarding home use of heating pads should include which of the following?
Correct Answer: B,E,F
Rationale: Heating pads should be used for 20-30 minutes (
B) to avoid burns, never lain on (E) to prevent prolonged heat exposure, and skin should be checked frequently (F). High temperatures (
A) increase burn risk, petroleum jelly (
C) can trap heat, and heat on swelling areas (
D) can worsen edema.
