A patient with a history of hypertension is admitted for a procedure. If the patient’s blood pressure decreases, which clinical manifestation would the nurse expect to see?

Choice A reason: Decreased blood pressure triggers the baroreceptor reflex, increasing sympathetic activity to raise heart rate and vasoconstriction to restore pressure. A decreased heart rate would occur with increased blood pressure, not hypotension, as parasympathetic activation dominates. This choice is incorrect as it opposes the body’s compensatory response to low blood pressure. Choice B reason: Erythema, or skin redness, results from vasodilation or inflammation, not directly from hypotension. While compensatory vasoconstriction occurs in hypotension, it reduces skin perfusion, potentially causing pallor, not erythema. This manifestation is unrelated to the cardiovascular response to decreased blood pressure, making this choice incorrect. Choice C reason: Increased temperature is not a direct response to decreased blood pressure. Hypotension triggers sympathetic activation, prioritizing heart rate and vasoconstriction to maintain perfusion. Temperature changes may occur in shock states, but they’re not primary manifestations of routine hypotension, making this choice irrelevant to the expected clinical response. Choice D reason: Decreased blood pressure activates the baroreceptor reflex, stimulating sympathetic nervous system activity. This increases heart rate (tachycardia) to enhance cardiac output, compensating for low pressure to maintain tissue perfusion. This is a primary physiological response to hypotension, making it the correct clinical manifestation expected in this scenario.
