A patient with PUD presents with a sudden onset of severe abdominal pain, vomiting, and signs of peritonitis. What is the nurse's priority action?

Correct Answer: B

Rationale: Signs of peritonitis suggest perforation, requiring immediate physician notification.

Correct Answer: B

Rationale: Both co-codamol and co-proxamol contain paracetamol which may be hepatotoxic. Cophenotrope has the constipating opioid diphenoxylate, but includes atropine whose unpleasant anticholinergic side-effects, including dry mouth, are designed to discourage over-use.

Correct Answer: A

Rationale: The digestive system breaks down food into fatty acids and glycerol, and the circulatory system transports these to cells for fat synthesis. Excretory removes waste, not nutrients. Immune and muscular and reproductive systems are unrelated to fat synthesis.

Correct Answer: C

Rationale: The digestive system processes food into nutrients for the body, making 'food-processing system' correct. Breathing relates to the respiratory system, nerves to the nervous system, and blood transport to the circulatory system.

Correct Answer: B

Rationale: The liver , stomach , and pancreas produce digestive juices (bile, gastric juice, pancreatic enzymes), but kidneys filter blood for urine, not digestive juices, making B correct.
