Correct Answer: C

Rationale: Placing the client on NPO status is the priority action for a client with acute pancreatitis. This step is crucial to rest the pancreas, prevent pancreatic stimulation, and decrease enzyme production. By withholding oral intake, the digestive system is given a chance to rest and recover. Administering intravenous fluids may be necessary but should come after placing the client on NPO status. Pain medication can be administered once the client is stabilized. Assessing the client's abdomen for distention is important but is not the initial priority in managing acute pancreatitis.

Correct Answer: A

Rationale: The correct answer is A: Headache. In a client with atrial fibrillation taking warfarin (Coumadin), a headache can be indicative of bleeding, which is a serious complication requiring immediate assessment and intervention. Monitoring for signs of bleeding is crucial when on anticoagulant therapy. Choices B, C, and D are not the most concerning. A prothrombin time of 15 seconds is within the therapeutic range for a client on warfarin, elevated liver enzymes may indicate liver dysfunction but are not directly related to the medication's side effects, and peripheral edema is not typically associated with warfarin use or atrial fibrillation in this context.

Correct Answer: D

Rationale: The correct first action for the nurse to take when preparing to insert a nasogastric tube (NGT) in a client is to explain the procedure to the client and obtain consent. It is crucial to ensure that the client is informed about the procedure, understands it, and consents to it before proceeding. Assessing the client's history for nasal trauma or surgery (Choice A) is important but can be done after obtaining consent. Asking the client to cough and deep breathe (Choice B) is not directly related to the initial step of preparing for NGT insertion. Measuring the length of the tube to be inserted (Choice C) is a necessary step but should come after explaining the procedure and obtaining consent.

Correct Answer: C

Rationale: Subcutaneous emphysema is the assessment finding that requires immediate intervention in a client with a chest tube following a pneumothorax. Subcutaneous emphysema can indicate a pneumothorax recurrence or air leak, which can compromise respiratory function and lead to serious complications. Oxygen saturation of 94% may be concerning but does not require immediate intervention as it is still within an acceptable range. Crepitus around the insertion site is common after chest tube placement and may not always indicate a problem. A blood pressure of 110/70 mmHg is within normal limits and does not require immediate intervention in this context.

Correct Answer: B

Rationale: When a client with major depressive disorder shows signs of increased energy, giving away belongings, and an elevated mood, it could indicate a shift towards suicidal behavior. Therefore, the best intervention for the nurse is to ask the client if she has had any recent thoughts of harming herself. This is crucial to assess the client's risk for suicide and provide necessary interventions. Choices A, C, and D are incorrect because they do not address the potential risk of harm to the client and do not prioritize the immediate assessment required in this situation.
