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: Contacting the health care provider is the most appropriate action because a change in the Doppler sound may indicate a potential complication, such as graft occlusion or compromised blood flow. Immediate assessment and intervention by the health care provider are essential to prevent further complications and ensure the patient's safety.

Choice B reason: Rechecking the pulse in another 30 minutes is not advisable in this situation because it could delay necessary medical intervention. Prompt communication with the health care provider is crucial to address the underlying issue and provide timely care.

Choice C reason: Measuring the ankle-brachial index can provide valuable information about blood flow in the lower extremities, but it is not the immediate priority when a significant change in the Doppler sound is detected. Contacting the health care provider for further assessment and instructions takes precedence.

Choice D reason: Administering an oral anticoagulant is not an appropriate action without the direct instruction from a health care provider. The nurse must first report the change in the Doppler sound to the provider and follow their specific orders regarding medication and treatment.

Choice A reason: Respiratory status is crucial to monitor because patients with acute neurological deficits, such as those seen in strokes, are at risk of respiratory compromise. This can be due to weakened respiratory muscles or aspiration, which could lead to pneumonia or other respiratory complications.

Choice B reason: Monitoring liver enzymes is not directly related to the acute management of a stroke patient. Liver enzymes would be more relevant in cases where liver function or hepatic issues are suspected, but not for this specific scenario.

Choice C reason: Blood pressure monitoring is vital, as hypertension is a significant risk factor for stroke. Maintaining appropriate blood pressure is essential to prevent further neurological damage and complications. Acute changes in blood pressure can indicate worsening or improvement of the patient's condition.

Choice D reason: Neurological status should be continuously monitored to assess the progression of the patient's stroke symptoms. This includes checking for changes in level of consciousness, motor function, speech, and other neurological signs. Prompt detection of changes can guide immediate interventions.

Choice E reason: Potassium level monitoring is not a primary focus in the acute management of stroke. While electrolyte balance is important, it is not as critical as respiratory status, blood pressure, and neurological status in this context.
