Which clinical manifestation should a nurse monitor in a patient experiencing anaphylaxis?

In a patient experiencing anaphylaxis, monitoring for hypotension is critical. Anaphylaxis is a severe allergic reaction that can lead to the release of large amounts of histamine and other inflammatory mediators, causing widespread vasodilation and increased vascular permeability. This results in a significant drop in blood pressure, leading to hypotension.

Hypotension during anaphylaxis occurs rapidly and can be life-threatening if not treated promptly. The decrease in blood pressure can cause inadequate perfusion to vital organs, resulting in symptoms such as dizziness, fainting, and, in severe cases, shock. Recognizing and addressing hypotension immediately is essential for the effective management of anaphylaxis, often requiring interventions such as the administration of epinephrine and intravenous fluids.

In contrast, bradycardia, diuresis, and hypertension are not typical manifestations associated with anaphylaxis. Bradycardia may occur in other cardiac conditions but is not a hallmark of anaphylactic reactions. Diuresis, the increased production of urine, is not relevant in the acute management of anaphylaxis. Lastly, hypertension typically does not occur during anaphylaxis; in fact, the opposite is true as vasodilation leads to decreased blood pressure. Thus, hypot
