The nurse is caring for a patient who has had a pressure injury. When assessing the wound, which finding causes the greatest concern for the nurse?

A.

Amber fluid

B.

Clear drainage

C.

Purulent, draining wound

D.

Blood-tinged fluid

Answer and Explanation

The Correct Answer is C

Choice A reason: Amber fluid is typically a sign of serous exudate, which is a normal part of the inflammatory process and wound healing. It indicates the body's immune response to the injury and is generally not a cause for concern unless the volume significantly increases or changes in appearance.

Choice B reason: Clear drainage, or serous fluid, is also a normal finding in wound healing. It indicates that the wound is exuding plasma, which helps to keep the wound moist and supports the healing process. This type of drainage is typically not worrisome unless there are other signs of infection or complications.

Choice C reason: Purulent, draining wound is a major concern as it indicates the presence of pus, which is often a sign of infection. Purulent drainage can be yellow, green, or brown and is usually thick and malodorous. The presence of pus suggests that there are bacteria or other pathogens in the wound, and immediate medical intervention is necessary to prevent further complications and promote healing.

Choice D reason: Blood-tinged fluid, or serosanguinous drainage, is common in fresh wounds or after debridement. It indicates a mixture of plasma and red blood cells and can be seen in the early stages of wound healing. While it is generally not alarming, the nurse should monitor the volume and changes in the drainage to ensure there are no signs of excessive bleeding or infection.

Correct Answer is C

Explanation

Choice A reason: While blood glucose monitoring is essential for patients receiving TPN, it is not specifically necessary to obtain samples from a central line. Blood glucose levels can be monitored through peripheral blood samples.

Choice B reason: There is actually an increased risk of infection with central lines compared to peripheral lines due to the invasive nature of central line placement and its location. Proper aseptic technique is critical to minimize this risk.

Choice C reason: The hypertonic solution will be more rapidly diluted when given through a central line. This is a critical point because the central veins have a higher blood flow and larger volume, which helps to quickly dilute the hypertonic TPN solution. This reduces the risk of phlebitis and damage to the smaller peripheral veins, making central lines more suitable for infusing highly concentrated solutions like 25% dextrose.

Choice D reason: While a central line can allow for the rapid administration of infusions, this is not the primary reason for its use with TPN. The key factor is the dilution of the hypertonic solution, as central lines handle high osmolarity solutions better than peripheral veins.

Correct Answer is ["A","B"]

Explanation

Choice A reason: Warfarin should be held before surgery due to its anticoagulant properties. Continuing warfarin increases the risk of excessive bleeding during and after surgery. The patient's INR level is already elevated, indicating a higher risk of bleeding.

Choice B reason: Metformin should be held before surgery, especially for patients undergoing procedures that involve the use of contrast dye or anesthesia. Metformin can cause lactic acidosis in patients with renal impairment or when kidney function is affected by contrast agents or surgery.

Choice C reason: Lisinopril is an ACE inhibitor used to manage blood pressure. While some guidelines suggest holding ACE inhibitors before surgery due to the risk of intraoperative hypotension, this decision is often individualized based on the patient's condition and the type of surgery. It is not as universally indicated to be held as warfarin and metformin.
