What effect does temperature control have on the patient’s cardiac and respiratory systems during a surgical procedure?
  1. The hypothermic patient may begin to shiver, causing increased respiratory effort.
  2. The method of heat regulation is depressed, causing increased oxygen consumption.
  3. The blood vessels dilate, caused a disrupted acid-base balance.
  4. Both B and C
Explanation
Answer: D-During surgery, the patient’s method of heat regulation may be depressed, causing increased oxygen consumption; in addition, the blood vessels dilate, causing a disrupted acid-base balance. The effects of temperature instability during the surgical period move beyond patient comfort and shivering. Temperature control affects the metabolic processes in the body such that alterations in temperature regulation can cause increased respiratory distress.
