Four hours after surgery, a client reports nausea and begins to vomit. The nurse notes that the client has a scopolamine transdermal patch applied behind the ear. Which action should the nurse take?

A. This intervention is likely to be ordered due to the patient's fever and elevated heart rate, which may suggest dehydration or the need for increased fluid intake to support hemodynamic stability and mitigate the effects of fever and potential dehydration from fever and nausea.
B. Given the diagnosis of Pneumocystis pneumonia, the patient will likely be on or start antibiotics specific to this infection, such as trimethoprim-sulfamethoxazole. Monitoring for adverse reactions is crucial, especially in a newly diagnosed HIV-positive patient who might be starting multiple new medications.
C. While it is important to monitor CD4 counts in HIV-positive patients to guide treatment decisions, repeating the CD4 count immediately might not be prioritized unless there are specific clinical changes that suggest a rapid decline in immune function. Given the recent test results showing a CD4 count of 443 cells/mm^3, immediate retesting might not be clinically justified unless guided by other symptoms or considerations not detailed here.
D. Pneumocystis pneumonia does not require airborne isolation as it is not typically contagious between people under normal circumstances. Instead, it arises as an opportunistic infection in individuals with weakened immune systems. Hence, this order would not be appropriate unless there were other infections suspected that require such precautions.
E. The patient reports severe nausea, which not only is distressing but can also prevent the patient from taking oral medications and maintain necessary nutrition. Administering an antiemetic can help manage this symptom effectively.

A. Not a priority compared to monitoring vital signs and ensuring adequate oxygenation.

B: Increased oxygen flow is necessary to manage the client's respiratory distress and history of smoking. Correct Answer: 3 L, not 1 L as initially listed.
C: Acetaminophen 350 mg PO q4h for temperature greater than 101 F (38.3°C): Important for fever management but not the first priority in acute respiratory distress.
D: Helps maintain hydration but is secondary to respiratory support in this scenario.

E: Not applicable as there is no immediate need for surgery or risk of aspiration currently indicated.
F: Important for medication administration and fluid balance but follows after ensuring respiratory function.
G: Useful for diagnosing the cause of respiratory symptoms but not a first-line action.

H: Essential for continuously assessing the client's respiratory and cardiac status due to difficulty breathing.
