Two days following abdominal surgery a client begins to report cramping abdominal pain, and the nurse's inspection of the abdomen indicates slight distention. Which action should the nurse implement first?
- A. Encourage the client to ambulate
- B. Offer ice chips or warm liquids

Rare causes of bloody diarrhoea include:
- A. Campylobacter infection
- B. Peutz-Jegher's syndrome
- C. Enterotoxigenic E. coli
- D. Crohn's disease
Correct Answer: B
Rationale: Rare causes of bloody diarrhoea include conditions like Peutz-Jegher's syndrome which is a genetic disorder causing polyps in the gastrointestinal tract. Campylobacter Shigella and Enterotoxigenic E. coli are common causes of infectious diarrhoea while Crohn's disease is a chronic inflammatory condition.
What does the nurse explain that a ventricular septal defect will allow?
- A. Blood to shunt left to right, causing increased pulmonary flow and no cyanosis
- B. Blood to shunt right to left, causing decreased pulmonary flow and cyanosis
- C. No shunting because of high pressure in the left ventricle
- D. Increased pressure in the left atrium, impeding circulation of oxygenated blood in the circulating volume
Correct Answer: A
Rationale: Pulmonary blood flow is increased when a ventricular septal defect exists. The blood shifts from left to right because of the higher pressure in the left ventricle. This particular shift does not cause cyanosis.
