A nurse is preparing the skin of a client scheduled for cardiac surgery. What is the purpose of surgical skin cleaning preparation?

Assessing the surgical site before surgery

Providing comfort for the client

Reducing the risk of post-operative wound infection

Sterilizing the skin for easier scalpel cutting

Answer and Explanation

The Correct Answer is C

A. Assessing the surgical site before surgery: While assessing the surgical site is important, it is not the primary purpose of skin cleaning preparation. The focus is on reducing infection risk.
B. Providing comfort for the client: Comfort may be a secondary benefit, but it is not the main goal of surgical skin cleaning. The primary purpose is to reduce infection risk.
C. Reducing the risk of post-operative wound infection: Surgical skin cleaning preparation is aimed at minimizing the number of microorganisms on the skin to reduce the risk of postoperative wound infections. This is the key reason for preoperative skin preparation.
D. Sterilizing the skin for easier scalpel cutting: Skin cannot be completely sterilized, and the ease of scalpel cutting is not related to the cleanliness of the skin. The goal is infection control, not making the skin easier to cut.

Correct Answer is C

Explanation

A. Respiratory acidosis without compensation: The pH of 7.22 indicates acidosis, but the HCO3 level of 23 mEq/L suggests that compensation is occurring because the HCO3 is within the normal range for respiratory acidosis.
B. Metabolic acidosis with full compensation: The high PaCO2 level is more indicative of respiratory issues, not metabolic acidosis. Additionally, compensation for metabolic acidosis would show elevated HCO3.
C. Respiratory acidosis with partial compensation: The elevated PaCO2 and low pH indicate respiratory acidosis. The normal HCO3 level suggests partial compensation by the kidneys.
D. Metabolic acidosis without compensation: The elevated PaCO2 and normal HCO3 suggest respiratory acidosis rather than metabolic acidosis.

A. Deep breathing and coughing exercises daily B. Removal of compression stockings at night C. Floating the heels while lying in bed D. Leg exercises ten times per hour while awake

Correct Answer is D

Explanation

A. Deep breathing and coughing exercises daily: These are important for preventing respiratory complications but do not specifically address the prevention of thrombosis.
B. Removal of compression stockings at night: Compression stockings should generally be worn continuously to prevent venous stasis and thrombosis.
C. Floating the heels while lying in bed: This helps prevent pressure ulcers but is not a primary intervention for preventing thrombosis.
D. Leg exercises ten times per hour while awake: This is the correct choice. Regular leg exercises improve circulation and help prevent venous stasis, thereby reducing the risk of thrombosis.
