Correct Answer: B

Rationale: In acute pancreatitis, a low blood pressure of 95/60 mmHg is the most concerning finding as it may indicate hypovolemia or shock, which are critical conditions requiring immediate intervention. Pain radiating to the back is a common symptom of pancreatitis but is not as immediately life-threatening as hypotension. Elevated serum amylase levels and absent bowel sounds are typical findings in acute pancreatitis and may indicate pancreatic inflammation and gastrointestinal motility issues, respectively, but they are not as acutely concerning as hypotension.

Correct Answer: A

Rationale: Scheduling rest periods during morning care is essential for managing dyspnea and fatigue in the client. This approach allows the client to pace themselves and catch their breath, promoting comfort and reducing symptoms. It is crucial to provide breaks to prevent overwhelming the client and exacerbating their symptoms. Discontinuing morning care for 2 days (choice B) is not a suitable solution as it does not address the underlying issue and may lead to neglect of essential care. Performing all care as quickly as possible (choice C) can worsen the client's symptoms and compromise their well-being by increasing stress and exertion. Asking a family member to bathe the client (choice D) does not address the need for rest periods during care and may not be feasible or appropriate in all situations.

Correct Answer: C

Rationale: When a client requires parenteral nutrition (PN) with a high dextrose concentration, such as 20%, it typically has a high osmolarity. High osmolarity solutions should be infused through a central venous line to prevent peripheral vein irritation and potential complications. Therefore, preparing the client for a central venous line is essential for the safe administration of PN with high dextrose. Monitoring blood glucose levels daily is important but not directly related to the need for a central venous line. Changing the PN infusion bag every 24 hours helps prevent bacterial contamination, but it is not the most critical action in this scenario. Administering the PN and fat emulsion together or separately is a matter of compatibility and administration guidelines, but it is not the key concern in this situation.

Correct Answer: D

Rationale: In acetaminophen poisoning, liver damage is a significant concern due to the drug's metabolism in the liver. Monitoring liver enzymes such as AST and ALT is crucial as they indicate liver function and damage. Prothrombin time (PT) and partial thromboplastin time (PTT) (Choice A) are coagulation studies and are not the priority in acetaminophen poisoning. Red blood cell and white blood cell counts (Choice B) are not directly related to acetaminophen poisoning. Blood urea nitrogen and creatinine levels (Choice C) assess kidney function, but liver enzymes are more specific for evaluating liver damage in acetaminophen poisoning.

Correct Answer: A

Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.
