- A. Sore muscles after working in the garden for several hours
- B. An infected cut on the plantar surface of the foot
- C. A newly jammed thumb joint
- D. A postoperative patient with a body temperature of 95°F
Correct Answer: D
Rationale: Heat is indicated for sore muscles (A) to relax tissues, but not for infected cuts (B) as it may worsen infection, newly jammed joints (C) due to swelling, or hypothermia (D) as it requires warming but not localized heat. Hypothermia (D) is the least suitable.

- A. Use the highest temperature setting for maximum heat penetration.
- B. Set a timer for no longer than 20 to 30 minutes.
- C. Use a thin layer of petroleum jelly on skin to prevent burns.
- D. Use heat on areas that continue to swell.
- E. Never lie on top of a heating pad.
- F. Check the skin under the heating pad every 10 minutes for excessive redness.
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.

- A. Hypothermia.
- B. Fever reduction.
- C. Pain relief.
- D. Hemostasis.
- E. Prevention of swelling.
- F. Reduction of edema.
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.

- A. Slowed metabolism
- B. Ischemia of cells
- C. Reduction of body's oxygen requirements
- D. Phagocytosis
Correct Answer: A,C
Rationale: Systemic cooling in cardiovascular surgery slows metabolism (A) and reduces oxygen requirements (C) to protect organs. Ischemia (B) is a potential risk, not a desired effect, and phagocytosis (D) is unrelated.

- A. 60 minutes.
- B. 45 minutes.
- C. 30 minutes.
- D. 15 minutes.
Correct Answer: C
Rationale: A tepid bath for fever reduction in children should not exceed 15 minutes (C) to prevent chilling or discomfort. Longer durations (A, B, D) increase risk of hypothermia or skin irritation.

- A. Phagocytosis
- B. Increased blood flow to tissue
- C. Vasoconstriction
- D. Decreased delivery of oxygen to tissue
- E. Delivery of increased level of nutrients to site
- F. Increase in cellular metabolism
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.
