An 80-year-old woman is undergoing total hip replacement surgery as treatment for severe osteoarthritis. During the procedure, the patient's core temperature falls to 31.6 C (88.9 F), necessitating interventions to address her hypothermia.

The surgical team recognizes that there are likely multiple causes of patient's hypothermia. Which of the following factors would the team be most justified in ruling out as a contributor?
A)
The cold environment in most operating theaters
B)
Decreased vasoconstriction as a result of anesthetic
C)
Decreased temperature adaptation due to her unconscious state
D)
Impaired thermoregulatory mechanisms due to anesthetic

Question 2

The nurse knows when caring for an elderly client who has a fractured right hip and is unable to undergo surgery due to his COPD, all joints with the exception of the right hip joint will need full range of motion exercises to prevent

A)
decubitus ulcer formation.
B)
tears in the tendons.
C)
contracture formation.
D)
muscle cellulitis.

Answer to Question 1

Ans:
C

Feedback:

Unconsciousness in and of itself is not an identified contributor to surgical hypothermia. The cold environment, decreased vasoconstriction, and impaired thermoregulation resulting from an anesthetic are all potential contributors.

Answer to Question 2

Ans:
C

Feedback:

Muscle atrophy and disuse contribute to wasting and weakening of the muscle tissue along with the development of joint contractures. Decubitus is usually caused by staying in one position for a long time, which results in compression of tissues and loss of circulation to the area. Tears in tendons usually result from intense physical exercise. Cellulitis is an infection usually as a result in a break in the skin (e.g., injury, surgery, or insect bites).
