When performing patient education regarding leg exercises, the nurse would explain that the purpose of the exercises is to

ease the stiffness from being on the operating table.

decrease pain from immobile extremities.

increase venous return and decrease stasis.

increase activity to help prevent atelectasis.

Answer and Explanation

The Correct Answer is C

A. Ease the stiffness from being on the operating table. While leg exercises can help relieve stiffness, their primary purpose is not to address the stiffness from surgery but to improve circulation and prevent complications.

B. Decrease pain from immobile extremities. Leg exercises may reduce discomfort associated with immobility, but the main goal is to prevent complications such as blood clots or deep vein thrombosis (DVT).

C. Increase venous return and decrease stasis. Leg exercises are primarily aimed at improving venous return to the heart and reducing the risk of stasis, which can lead to complications like DVT.

D. Increase activity to help prevent atelectasis. While increasing activity is important for overall recovery, leg exercises are more focused on circulation and preventing blood clots, not directly preventing atelectasis (a condition where the lungs partially collapse).

Correct Answer is C

Explanation

A. Time of last meal: Time of the last meal is essential for preventing aspiration during anesthesia but does not help determine the exact amount of anesthesia needed.

B. Pulse rate and blood pressure: Pulse rate and blood pressure are important for assessing the patient's cardiovascular status but are not directly used to calculate the amount of anesthesia needed.

C. Height and weight: Height and weight are critical for calculating the correct dose of anesthesia, as these factors affect the distribution and metabolism of the drug.

D. Respiratory rate and oxygen saturation: Respiratory rate and oxygen saturation are important for monitoring respiratory function, but they do not provide specific data needed to calculate the amount of anesthesia.

A. nausea and vomiting. B. delayed healing C. anorexia. D. hydration issues.

Correct Answer is B

Explanation

A. Nausea and vomiting. Nausea and vomiting can occur after surgery due to anesthesia and other factors. However, it is more common in patients of all ages who undergo certain types of surgery. Though these groups may be more susceptible, this is not the most specific risk.

B. Delayed healing. Both very young and older adult patients are at higher risk for delayed healing. In the very young, the immune system and cell regeneration processes are still developing, while in older adults, decreased circulation, chronic conditions, and slower cellular regeneration can impair wound healing.

C. Anorexia. Anorexia is not specific to surgical patients. While appetite loss can occur postoperatively, it is not as universally problematic in young or older surgical patients as delayed healing.

D. Hydration issues. Hydration issues can occur in all patients, especially following surgery, but they are particularly critical for the very young (due to smaller body mass and high fluid turnover) and the elderly (due to decreased kidney function and total body water). However, this is not as universally prevalent as delayed healing.
