A nurse is caring for a client with a cholelithiasis who has been scheduled for a laparoscopic cholecystectomy. Why is laparoscopic cholecystectomy preferred by surgeons over an open procedure?
Laparoscopic cholecystectomy poses fewer surgical risks than an open procedure.
Laparoscopic cholecystectomy can be performed in a clinic setting, while an open procedure requires an OR.
A laparoscopic approach allows for the removal of the entire gallbladder.
A laparoscopic approach can be performed under conscious sedation.
The Correct Answer is A
A. Laparoscopic cholecystectomy is less invasive, associated with fewer complications, shorter hospital stays, reduced postoperative pain, and quicker recovery — making it the preferred method.
B. It is not typically performed in a clinic setting; both laparoscopic and open procedures are done in an operating room.
C. Both procedures remove the entire gallbladder; the difference lies in the surgical approach, not the extent of removal.
D. General anesthesia is required for laparoscopic cholecystectomy, not conscious sedation.

Correct Answer is ["3.75"]
Explanation
Step 1: Calculate the infusion rate per hour:
1000 mL ÷ 10 hours = 100 mL/hour
Step 2: Calculate time to infuse remaining 375 mL:
375 mL ÷ 100 mL/hour = 3.75 hours
Step 3: Convert 0.75 hour to minutes:
0.75 × 60 = 45 minutes
Final answer: 3 hours and 45 minutes
Rationale:
The infusion rate is constant. Time remaining = remaining volume ÷ rate. Convert decimal hours to minutes for precise documentation.
