Correct Answer: B

Rationale: The correct answer is B. Clients with duodenal ulcers should avoid spicy foods and alcohol as they can exacerbate symptoms and delay healing. Choice A is incorrect because while antacids may help with symptoms, they are not the primary focus of medication teaching for duodenal ulcers. Choice C is not directly related to medication teaching for duodenal ulcers unless antibiotics are specifically prescribed. Choice D is incorrect as stopping all food intake is not recommended and can lead to other complications.

Correct Answer: C

Rationale: The correct answer is C. The second nurse should assist with compressions or breathing to ensure the patient receives adequate care during CPR. This immediate intervention is crucial in maintaining blood circulation and oxygenation to vital organs. Choice A is incorrect because simply relieving the nurse performing CPR may lead to a delay in essential life-saving measures. Choice B is incorrect as the primary focus should be on providing direct assistance rather than fetching equipment. Choice D is incorrect as validating the client's advanced directive is not the priority in this emergency situation.

Correct Answer: C

Rationale: The correct answer is C. Recognizing signs and symptoms of infection should be the nurse's first priority when developing a teaching plan for a client receiving chemotherapy. Chemotherapy often compromises the immune system, making patients more susceptible to infections. Early identification and prompt treatment of infections are crucial to prevent complications. Options A, B, and D are important aspects of care but recognizing signs of infection takes precedence due to the potential life-threatening consequences in clients undergoing chemotherapy treatment.

Correct Answer: B

Rationale: Prothrombin time (PT) measures the time it takes for blood to clot and is a critical indicator of bleeding risk in clients with liver dysfunction. Impaired liver function reduces clotting factor production, leading to an increased PT, which requires close monitoring. Monitoring BUN (Choice A) is more indicative of kidney function, not clotting ability. Aspartate aminotransferase (AST) (Choice C) and serum albumin (Choice D) are important indicators of liver function, but they do not directly assess the client's bleeding risk.

Correct Answer: D

Rationale: Administering a diuretic as prescribed is the most appropriate intervention to manage fluid volume in a client with ascites due to advanced liver disease. Diuretics help reduce fluid accumulation in the body, including the abdominal cavity where ascites occurs. Increasing sodium intake would worsen fluid retention, and encouraging more fluid intake can exacerbate ascites. Placing the client in a supine position does not directly address the fluid volume issue associated with ascites.
