Case Steven Q5: The nurse reports the following parameters: blood pressure 185/90 mmHg, heart rate 80/min, sinus rhythm on ECG, blood oxygenation 91%, and blood glucose 8 mmol/L. Does any of these parameters require correction at this time?

Correct answer is A: None of these parameters require correction at this time. In the acute setting of a suspected stroke, certain physiological parameters are often maintained at levels that might not be considered normal under other circumstances. Elevated blood pressure is common and can be beneficial initially, as it helps to ensure adequate perfusion to the brain. Aggressive lowering of blood pressure can reduce cerebral perfusion and worsen the ischemic injury. Similarly, elevated blood glucose levels are often observed in acute stroke due to stress hyperglycemia. Immediate normalization of blood glucose is not typically necessary unless levels are extremely high and posing an immediate risk. Blood oxygenation at 91% is slightly low, but immediate correction might not be critical unless it continues to drop or the patient shows signs of respiratory distress. Overall, these parameters are monitored and managed cautiously to avoid exacerbating the stroke.
