A nurse is providing care for a client who is scheduled for electroconvulsive therapy. Which of the following conditions should the nurse identify as an increased risk for complications?

Rationale:
A. Hypovolemia: Hypovolemia causes a decrease in PAWP due to reduced circulating blood volume and inadequate venous return to the heart. A low PAWP reflects decreased left ventricular preload, not an elevated value.

B. Hypotension: Hypotension alone does not directly increase PAWP. In fact, low blood pressure often accompanies decreased cardiac filling pressures. Elevated PAWP typically occurs with fluid overload or impaired ventricular function rather than simple hypotension.

C. Left ventricular failure: An elevated PAWP indicates increased left-sided heart pressures due to ineffective left ventricular pumping. Blood backs up into the pulmonary circulation, leading to pulmonary congestion and edema.

D. Cardiogenic shock: In cardiogenic shock, PAWP can be elevated due to impaired contractility, but it is accompanied by low cardiac output and hypotension. While related, the elevated PAWP in cardiogenic shock results from the underlying left ventricular failure, which is the primary cause of the pressure increase.

Rationale:

• Stool: The presence of blood and mucus in the stool (“currant jelly” stool) is classic for intussusception, caused by ischemia and mucosal sloughing of the affected bowel segment.

• Abdominal findings: A distended abdomen with a small, palpable, oblong mass in the right upper quadrant is characteristic of the telescoping bowel seen in intussusception.

• Pain rating: Severe, intermittent, colicky abdominal pain causing the child to draw knees to chest is hallmark of intussusception due to periodic intestinal obstruction and ischemia. Children with Crohn’s may report chronic mild to moderate pain, often intermittent. Pain in appendicitis is usually steady, localized and worsens over time.

• Vomiting : Vomiting is common in intussusception due to partial bowel obstruction, often light-colored and non-bilious in early stages. In appendicitis, nausea and vomiting are common early symptoms.

•Temperature: In Crohn's disease low-grade fever is common due to the chronic inflammatory process, while in appendicitis, low-grade fever is common due to inflammation or early infection.
