Correct Answer: B

Rationale: The correct answer is B: Monitor the client's intake and output. When a client with acute pancreatitis is on NPO status, the nurse's priority intervention is to monitor the client's intake and output. This is crucial to assess for signs of dehydration, electrolyte imbalances, and to ensure the client is responding appropriately to treatment. Administering antiemetic medication (choice A) may be necessary for managing nausea and vomiting but is not the priority over monitoring intake and output. Providing mouth care (choice C) and elevating the client's head of the bed (choice D) are important aspects of care but do not take precedence over monitoring intake and output to prevent complications in clients with NPO status due to acute pancreatitis.

Correct Answer: C

Rationale: A blood pressure of 88/52 mmHg indicates hypotension, which is a sign of worsening septic shock. Hypotension can lead to organ failure and requires immediate intervention. Elevated heart rate (choice A), mild fever (choice B), and slightly increased respiratory rate (choice D) are common in septic shock and may not necessarily indicate a deteriorating condition as much as hypotension does.

Correct Answer: D

Rationale: Elevating the head of the bed in a client with acute respiratory distress syndrome (ARDS) is essential to drain secretions and prevent aspiration. This position helps facilitate the removal of secretions from the airways, reducing the risk of aspiration pneumonia. Choices A, B, and C are incorrect as the primary reason for elevating the head of the bed in ARDS is to assist with secretion drainage and prevent complications associated with aspiration.

Correct Answer: B

Rationale: The correct teaching for a client prescribed warfarin is to report any signs of bleeding, such as unusual bruising, nosebleeds, or blood in the urine or stool. Warfarin is an anticoagulant that increases the risk of bleeding, so it is crucial for the client to promptly report any bleeding-related symptoms for evaluation by a healthcare provider. Choices A, C, and D are incorrect. Avoiding foods high in vitamin K, such as spinach, is more relevant for clients taking warfarin to maintain consistent vitamin K intake. Warfarin should be taken with food to avoid gastrointestinal upset, so taking it on an empty stomach is not recommended. Monitoring for changes in blood pressure is not directly related to warfarin therapy; instead, the focus should be on monitoring for signs of bleeding.

Correct Answer: C

Rationale: The correct answer is C: 'Check for bowel movement and changes in stool.' Intussusception can cause obstruction in the bowel, leading to symptoms like abdominal pain, vomiting, and 'currant jelly' stools. Monitoring for changes in bowel movement, especially the passage of 'currant jelly' stools, is crucial for early detection of worsening conditions. Choices A, B, and D are important assessments in pediatric care but are not as specific or crucial as checking for changes in bowel movement in a child diagnosed with intussusception.
