Correct Answer: D

Rationale: The correct answer is D: Encourage deep breathing. This is because encouraging deep breathing can help alleviate anxiety and promote relaxation, which can be beneficial in managing severe chest pain. Administering nitroglycerin (A) should only be done after assessing the client's condition and confirming it is safe to do so. Providing pain relief (B) may be necessary, but addressing the root cause of the pain should be the priority. Monitoring ECG (C) is important but should come after ensuring the client's immediate needs are addressed.

Correct Answer: B

Rationale: The correct answer is B: Monitor abdominal pain. This is the priority assessment for a client with acute pancreatitis because it helps determine the severity of the condition and guides the treatment plan. Abdominal pain is a key symptom of pancreatitis and monitoring its intensity, location, and changes over time is crucial. Assessing vital signs (choice A) is important but secondary to monitoring pain. Monitoring serum amylase levels (choice C) is relevant for diagnosis but not immediate priority. Performing a CT scan (choice D) may be necessary later for further evaluation but is not the initial priority in managing acute pancreatitis.

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Preventing infiltration of calcium is crucial to avoid tissue necrosis and sloughing. 2. Infiltration of calcium can lead to severe tissue damage and potential harm to the patient. 3. Monitoring for signs of infiltration during administration of electrolyte solutions is essential. 4. Administering calcium-containing solutions cautiously can prevent serious complications. 5. Ensuring proper placement of the IV line and monitoring for any signs of infiltration is key. Summary: A: Infusing hypertonic solutions rapidly can lead to adverse effects, such as fluid overload. B: Limiting potassium to 80 mEq per liter is important, but not directly related to preventing calcium infiltration. D: Reevaluating digitalis dosage is important in clients receiving electrolyte solutions but not directly related to preventing calcium infiltration.

Correct Answer: A

Rationale: The correct answer is A because assessing capillary refill indicates adequate blood flow, warm toes suggest good circulation, and no discomfort indicates proper alignment and fit of the cast. Choice B is incorrect as posterior tibial pulses are not directly related to cast assessment. Choice C is incorrect as moist skin and pain threshold are not specific to cast assessment. Choice D is incorrect as discomfort of the metacarpals is not a comprehensive assessment of a cast.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. In shock, the priority nursing action is to restore intravascular volume to improve tissue perfusion. IV fluids help increase blood pressure and cardiac output, addressing the underlying cause of shock. Monitoring vital signs (B) is important but administering fluids takes precedence. Administering fluids (C) is a general term and does not specify the urgency of IV fluids. Administering blood transfusion (D) may be indicated in certain types of shock but is not the initial priority.
