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 choice b. Chest pain and dysrhythmia. Choice A rationale: Decreasing gastrointestinal (GI) cramping and nausea are not typical adverse effects of vasopressin. In fact, vasopressin can cause abdominal cramps and nausea as side effects. Choice B rationale: Chest pain and dysrhythmia are significant adverse effects of vasopressin. Vasopressin can cause vasoconstriction, leading to myocardial ischemia and arrhythmias. Choice C rationale: Vasodilation of the extremities is not an adverse effect of vasopressin. Instead, vasopressin typically causes vasoconstriction, which can lead to peripheral ischemia. Choice D rationale: Hypotension and tachycardia are not common adverse effects of vasopressin. Vasopressin is more likely to cause hypertension due to its vasoconstrictive properties.
