A client with bleeding esophageal varices receives vasopressin intravenously (IV). Which adverse effect should the nurse monitor for during the IV infusion of this medication?

The correct answer is B Choice A reason: Vasopressin is not typically associated with decreasing GI cramping and nausea. It is used to treat diabetes insipidus and to reduce stomach bloat for some procedures and after some surgeries. Choice B reason: Vasopressin can cause chest pain or pressure, and fast, slow, or abnormal heartbeat, which are indicative of dysrhythmia. These are known side effects of vasopressin and should be monitored during IV infusion. Choice C reason: Vasopressin causes vasoconstriction, not vasodilation. It tightens small blood vessels, which is the opposite of vasodilation. Choice D reason: While vasopressin can cause bradycardia (slow heart rate), hypotension is not a common effect as it is used to treat low blood pressure. Tachycardia (fast heart rate) is not a typical side effect of vasopressin.
