Correct Answer: B

Rationale: The correct intervention to help manage the client's pain in acute pancreatitis is to place the client in a side-lying position with knees bent. This position can alleviate abdominal pain by reducing pressure on the pancreas and improving comfort. Encouraging deep breathing exercises (Choice A) is beneficial for other conditions but may not directly help alleviate abdominal pain in pancreatitis. Administering oral analgesics (Choice C) may be necessary but is not the initial priority for managing pain in acute pancreatitis. Encouraging the client to take small sips of water (Choice D) is important for hydration but is not directly related to pain management in this context.

Correct Answer: C

Rationale: When a client on heparin reports tarry stools, it can be indicative of gastrointestinal bleeding. The correct action for the nurse is to monitor the stools for blood and review the Partial Thromboplastin Time (PTT) results. This is essential to detect any potential bleeding complications associated with heparin therapy. Option A is incorrect because warfarin is not the immediate intervention for tarry stools in a client on heparin. Option B is irrelevant to the situation described. Option D is incorrect as Vitamin K is the antidote for warfarin, not heparin.

Correct Answer: C

Rationale: Irrigating and redressing a leg wound is a common task within the PN's scope of practice, making this assignment appropriate. Tasks like testing stool specimens for occult blood and assisting with ambulation of a client with a chest tube may require a higher level of training and assessment, typically performed by RNs. Admitting a client from the emergency room involves a comprehensive assessment and decision-making process, which is usually within the RN's responsibility.

Correct Answer: C

Rationale: In SIADH, there is excessive ADH secretion leading to water retention and dilutional hyponatremia. The most crucial intervention is to restrict fluid intake to prevent further fluid overload and worsening of hyponatremia. Encouraging oral hydration (choice A) would exacerbate the condition by adding more fluids. Monitoring for signs of dehydration (choice B) is not appropriate as the client is at risk of fluid overload. Administering IV fluids (choice D) would worsen the hyponatremia and should be avoided.

Correct Answer: B

Rationale: Prothrombin time (PT) is the most important laboratory value to monitor for clients on warfarin therapy. PT helps determine how long it takes blood to clot and ensures the warfarin dose is within the therapeutic range to prevent either excessive bleeding or clotting. Monitoring platelet count is important for assessing the risk of bleeding, but PT is more specific to warfarin therapy. Creatinine level and BUN are indicators of kidney function and are not directly related to warfarin therapy.
