Correct Answer: B

Rationale: The most important action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. This action helps prevent obstruction, ensures proper drainage, and reduces the risk of infection. Changing the catheter every 72 hours is not necessary unless clinically indicated and may introduce unnecessary risk. Cleaning the perineal area with antiseptic solution daily is important for general hygiene but not the most critical action for catheter-related infection prevention. Irrigating the catheter with normal saline every shift is not a routine nursing intervention for catheter care and may increase the risk of introducing pathogens.

Correct Answer: D

Rationale: In acute pancreatitis, hypocalcemia (low serum calcium) is a critical finding that is associated with a poor prognosis and requires immediate attention. Serum amylase and lipase are typically elevated in acute pancreatitis due to pancreatic inflammation, but they are not indicators of severity. Blood glucose levels may be elevated due to stress or underlying conditions but are not directly related to the severity of acute pancreatitis. Therefore, the most concerning value in this scenario is the low serum calcium level, which can have significant implications for the client's prognosis.

Correct Answer: A

Rationale: To calculate the mL/hr rate for the infusion, divide the total volume (750 mL) by the total time (7 hours). 750 mL · 7 hours = 107 mL/hr. This means that the pump should be set to deliver approximately 107 mL/hr. Choice B (75 mL/hr) is incorrect because it does not reflect the correct calculation. Choice C (90 mL/hr) is incorrect as it does not align with the accurate calculation. Choice D (60 mL/hr) is incorrect as it does not match the correct mL/hr rate obtained through the calculation.

Correct Answer: C

Rationale: The correct answer is C. This statement reflects the client's understanding of advance directives, as it indicates a specific preference regarding life-sustaining treatment. Advance directives enable individuals to outline their healthcare preferences, including decisions about treatments they wish to receive or avoid. Choice A mentions family members but doesn't address specific healthcare wishes; choice B focuses on the surgery rather than personal directives; choice D discusses doctor approval but lacks details about the directive itself.

Correct Answer: B

Rationale: The correct answer is B. Asking the client if they want to schedule prayer times during the day demonstrates respect and consideration for Islamic practices. Providing halal options (choice A) is important for dietary requirements in Islam, but it may not address the client's spiritual needs. Avoiding discussing care in front of the client's family (choice C) is not directly linked to Islamic practices and may not necessarily enhance cultural responsiveness. Offering daily communion (choice D) is associated with Christian religious practices, not Islamic practices, and may not meet the client's religious needs.
