A patient is admitted to the hospital for a splenectomy. The nurse understands that the health-care provider prescribes an injection of vitamin K prior to surgery for which action?

To reduce risk of infection

To dry gastric secretions

To promote postoperative healing

To correct a clotting problem

Answer and Explanation

The Correct Answer is D

A.   While vitamin K plays a role in immune function, its administration prior to surgery primarily aims to correct potential clotting abnormalities rather than prevent infection.

B.   Vitamin K does not affect gastric secretions. Its role in this context is unrelated to gastric function.
C.   While vitamin K is involved in various physiological processes, its administration prior to surgery is primarily aimed at preventing bleeding complications by ensuring adequate clotting factor synthesis.
D.   Vitamin K is essential for the synthesis of clotting factors in the liver.

Administering vitamin K prior to surgery helps ensure adequate levels of clotting factors, reducing the risk of bleeding during and after the procedure.

A. "Wear tight fitting clothes." B. "Take baths instead of showers." C. "Empty the drainage bag at the same time each day." D. "Secure the tubing to your clothing"

Correct Answer is D

Explanation

A. Tight fitting clothes may put pressure on the T-tube insertion site and interfere with drainage. Loose-fitting clothing is recommended.
B. Showering is typically preferred over baths to keep the T-tube site clean and dry.

Baths may increase the risk of infection.

C. Regular emptying of the drainage bag helps prevent excessive weight, which can pull on the T-tube and cause discomfort or displacement. However, it should necessarily be emptied at the same time each day.
D. Securing the tubing to clothing helps prevent accidental dislodgment or pulling on the T-tube, reducing the risk of complications.
