Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. Peritonitis is an inflammation of the peritoneum often caused by infection. Administering antibiotics is crucial to combat the infection. It is important to treat the underlying cause first before focusing on symptom management. Administering analgesics (B) may provide temporary relief but won't address the infection. Applying an ice pack (C) is not appropriate for peritonitis as it won't treat the infection. Performing a laparotomy (D) is a surgical procedure that may be necessary in severe cases but is not the initial nursing action.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. Oxygenation is the priority in stroke management to ensure adequate oxygen supply to the brain. Oxygen therapy can help reduce hypoxia, which is crucial in the acute phase of a stroke. Administering aspirin (B) is important but comes after ensuring oxygenation. Administering thrombolytics (C) requires proper assessment and diagnostic confirmation, not an immediate priority. Placing the client in a supine position (D) may worsen stroke symptoms if there is compromised blood flow, so it is not recommended as the initial action.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. Oxygen administration is the first intervention for shock as it helps improve oxygenation to vital organs. Lack of oxygen can worsen shock. Administering IV fluids (choice B) could be the second step to improve perfusion. Monitoring respiratory rate (choice C) is important but not the first intervention. Administering pain medication (choice D) is not a priority in managing shock.

Correct Answer: C

Rationale: The correct answer is C: Shortness of breath and chest pain. This is most concerning because it could indicate a pulmonary embolism, a serious complication of DVT where a blood clot travels to the lungs. Shortness of breath and chest pain are signs of compromised respiratory and cardiac function. A: Pain and swelling in the leg are common symptoms of DVT but not as concerning as symptoms of a pulmonary embolism. B: Redness and warmth around the affected area are typical signs of inflammation associated with DVT but do not indicate a life-threatening complication like a pulmonary embolism. D: Pale skin and decreased pulse in the affected leg could be signs of compromised circulation due to DVT, but they are not as immediately life-threatening as symptoms of a pulmonary embolism.

Correct Answer: C

Rationale: Correct Answer: C - Administer IV fluids Rationale: 1. Assess patient's fluid status and hydration level. 2. IV fluids help maintain adequate hydration during hemodialysis. 3. Prevents hypotension and ensures stable blood pressure during the procedure. 4. Improves overall hemodialysis efficiency and patient safety. Summary: A: Checking patency is important, but not the primary intervention for hemodialysis. B: Monitoring for bleeding is crucial but not specific to AVF assessment. D: Applying an airtight dressing is not necessary for AVF assessment.
