A nurse evaluates the following arterial blood gas values in a patient: pH 7.48, PaO 98 mm Hg, PaCO 28 mm Hg, and HCO - 22 mEq/L (22 mmol/L). Which patient condition does the nurse correlate with these results?

A. “Call your surgeon if you have any questions at home.”

This instruction is important as it encourages the patient to seek help and clarification if they have any concerns or questions about their postoperative care at home. However, while communication with the surgeon is essential, it is not as immediately critical as ensuring proper hand hygiene when dealing with wound care and drain management.

B. ”Eat a diet high in protein, iron, zinc, and vitamin C.”

Nutritional advice is crucial for postoperative recovery, as a balanced diet high in protein, iron, zinc, and vitamin C can promote wound healing and overall recovery. However, while important for long-term recovery and healing, dietary recommendations do not directly address the immediate risk of infection or complications associated with wound care and drain management.

C. “Wash your hands before touching the drain or dressing."

This instruction is the most important in this context because proper hand hygiene is crucial for preventing infections during wound care and drain management. Clean hands significantly reduce the risk of introducing harmful bacteria or contaminants to the surgical site, which can lead to infections and other complications. Ensuring that the patient washes their hands before touching the drain or dressing is a fundamental measure for promoting wound healing and preventing postoperative complications.

D. “Be sure you keep all your postoperative appointments.”

Keeping postoperative appointments is important for ongoing assessment, monitoring, and follow-up care. However, while essential for overall recovery and management of postoperative issues, it is not as immediate or directly related to the patient's ability to manage their dressing and drain at home.

1. A. How many people live in your home?

   This question pertains to social and environmental factors but is not directly related to assessing skin inflammation on the chest. While social factors can impact overall health, such as stress levels or exposure to infectious agents, the number of people living in the client's home is unlikely to be directly related to a new skin inflammation unless there are specific circumstances, such as sharing personal care products or close contact with others who have similar skin issues.

   B. Did you have a recent exposure to irritants?

   This question is highly relevant to assessing a new skin inflammation on the chest. Exposure to irritants or allergens can trigger or worsen skin conditions, such as contact dermatitis or allergic reactions. By asking about recent exposure to potential irritants like new detergents, soaps, fabrics, chemicals, or environmental factors, the nurse can gather important information to identify possible triggers for the skin inflammation.

   C. Is nausea associated with your rash?

   Nausea is typically not directly associated with a skin rash or inflammation unless there is a systemic condition or allergic reaction causing both symptoms. While it's important to assess for any systemic signs or symptoms that may be related to the skin condition, such as fever or malaise, specifically asking about nausea may not provide relevant information about the skin inflammation on the chest.

   D. What is your body mass index?

   Body mass index (BMI) is a measure of body weight relative to height and is not directly related to assessing a new skin inflammation on the chest. While obesity or changes in body weight can sometimes contribute to skin issues, such as friction-related dermatitis or hormonal changes affecting skin health, BMI alone is not a primary assessment parameter for localized skin conditions unless there are specific concerns related to weight-related skin problems.
