A patient who was involved in a motor vehicle crash has had a tracheostomy placed to allow for continued mechanical ventilation. How should the nurse interpret the following arterial blood gas results: pH 7.48, PaO₂ 85 mm Hg, PaCO₂ 32 mm Hg, and HCO₃ 25 mEq/L?

Choice A reason: Placing the patient in restraints for safety is not typically necessary unless the patient is agitated or a danger to themselves or others. This action is not directly addressing the acute condition of a stroke.

Choice B reason: Inserting an NGT (nasogastric tube) is not an immediate priority in the acute management of a stroke. This might be considered later if the patient has swallowing difficulties and needs nutritional support, but it is not a first-line intervention.

Choice C reason: Anticipating thrombolytic therapy for ischemic stroke is appropriate, as timely administration of thrombolytics can dissolve the clot and improve blood flow to the affected brain area, potentially reducing the severity of the stroke.

Choice D reason: Establishing IV access with normal saline is crucial for administering medications and maintaining hydration. It ensures that the patient can receive necessary interventions promptly.

Choice E reason: Placing the patient in the prone position is not appropriate in the management of an acute stroke. The prone position is generally used in respiratory conditions to improve oxygenation but is not relevant to stroke management.

Choice A reason: Checking the patient's temperature is important for assessing the severity of the pneumonia and monitoring for fever, but it is not the priority action before administering the first dose of vancomycin.

Choice B reason: Obtaining sputum cultures is the priority action because it allows for the identification of the causative organism and determination of its antibiotic susceptibility. This helps ensure that the prescribed antibiotic is appropriate for the patient's infection. Cultures should be obtained before starting antibiotic therapy to avoid interference with culture results.

Choice C reason: Checking the patient's blood pressure is important for overall patient assessment and monitoring, especially considering potential side effects of vancomycin. However, it is not the primary action needed before the first dose of the antibiotic.

Choice D reason: Drawing a blood specimen to evaluate the white blood cell count is useful for assessing the severity of the infection and the patient's immune response. However, this can be done after obtaining the sputum cultures and is not the immediate priority before administering the antibiotic.
