A nurse is reviewing the laboratory results of a client who is postoperative and has a respiratory rate of 7/min. The arteriaI blood gas (ABG) values include:

• pH 7.22
• PaCO2 68 mm Hg
• Base excess -2
• PaO2 78 mm Hg
• Oxygen saturation 80%
• Bicarbonate 28 mEq/L

Which of the following interpretations of the ABG values should the nurse make7

A. Change the dressing when it is saturated:

This intervention is the most appropriate for managing a deep wound with a wet to-damp dressing. Wet to-damp dressings are designed to maintain a moist environment conducive to wound healing. Changing the dressing when it becomes saturated with wound exudate helps prevent excessive moisture accumulation, which can lead to skin maceration and potential infection. It ensures that the wound bed remains in an optimal healing environment and reduces the risk of complications.

B. Assess the wound bed once a day:

Assessing the wound bed is an essential part of wound care, as it allows the nurse to monitor healing progress, assess for signs of infection, and evaluate the effectiveness of the chosen dressing. However, the frequency of wound bed assessment may vary depending on the specific patient's needs and the type of dressing being used. While daily assessment is generally recommended, it does not directly dictate the timing of dressing changes for wet to-damp dressings, which are primarily changed based on saturation levels.

C. Contact the provider when the dressing leaks:

Contacting the provider when the dressing leaks or when there are concerns or complications is an important step in patient care. Leaking dressings can indicate issues with the dressing application, excessive wound exudate, or potential complications such as infection. It's crucial to inform the provider promptly so that appropriate interventions can be implemented, but this instruction is more reactive and does not specifically address the timing of dressing changes.

D. Change the dressing every 6 hours:

Changing the dressing every 6 hours is not typically recommended for wet to-damp dressings unless specifically indicated based on the patient's condition and the amount of wound exudate. Frequent dressing changes can disrupt the healing process, cause unnecessary trauma to the wound bed, and increase the risk of infection. Dressing change frequency should be based on the assessment of wound exudate and the dressing's ability to maintain a moist environment.

A. “All preoperative patients get this medication.” This statement is too broad and not entirely accurate. While many preoperative patients do receive famotidine (Pepcid), it’s not a standard for all. Medications are prescribed based on individual patient needs and medical history.

B. “The physician prescribed this medication for you.” While this is technically true, it doesn’t provide the patient with an understanding of why the medication is necessary. As a nurse, part of your role is to educate patients about their medications.

C. “It helps prevent ulcers from the stress of the surgery.” This is the correct answer. Famotidine (Pepcid) is given to decrease the amount of acid produced in the stomach, which can help prevent stress ulcers that can occur due to the physical stress of surgery.

D. “Since you don’t have ulcers, I will have to ask.” This statement suggests uncertainty and a lack of knowledge about the medication’s purpose. It’s important for healthcare professionals to understand the medications they administer and be able to explain them to patients.
