A nurse is calculating fluid input for a client who is receiving a continuous IV infusion of 0.9% sodium chloride at 125 mL/hr and cefazolin 50 mL IV bolus every 4 hr. How many mL did the client receive per IV infusion over the past 24 hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["3300"]
Calculation:
- Calculate the total volume from the continuous IV infusion over 24 hours.
Continuous infusion rate = 125 mL/hr
Time = 24 hr
Volume from continuous infusion = 125 mL/hr × 24 hr
= 3000 mL.
- Calculate the total volume from the cefazolin IV bolus over 24 hours.
Cefazolin bolus volume per dose = 50 mL
Frequency = every 4 hr
Number of doses in 24 hr = 24 hr / 4 hr/dose
= 6 doses.
Volume from cefazolin bolus = 50 mL/dose × 6 doses
= 300 mL.
- Calculate the total IV fluid intake over 24 hours.
Total IV fluid intake = Volume from continuous infusion + Volume from cefazolin bolus
= 3000 mL + 300 mL
= 3300 mL.

Correct Answer is C
Explanation
Rationale:
A. Increased heart rate: Increased heart rate can be a general sign of infection or discomfort, but it is not the earliest indication of peritonitis in peritoneal dialysis. Other symptoms like cloudy effluent typically present earlier.
B. Generalized abdominal pain: While abdominal pain can be a sign of peritonitis, it typically appears after other signs like cloudy effluent, so it is not usually the earliest indicator.
C. Cloudy effluent: Cloudy effluent is the earliest and most indicative sign of peritonitis in peritoneal dialysis. This is due to the presence of white blood cells and bacteria in the peritoneal fluid, which is a hallmark of infection.
D. Fever: Fever is a later symptom of peritonitis. It typically occurs after the infection has progressed and is not the earliest sign to monitor for in the context of peritoneal dialysis.
Correct Answer is D
Explanation
Rationale:
A. "Keep your elbow in a flexed position." Keeping the elbow in a flexed position increases the risk of contractures, particularly in the case of upper body burns. The goal is to keep the joints extended to prevent the development of contractures.
B. "Remain in a side-lying position." A side-lying position is not ideal for preventing contractures in the upper body. The client should be positioned to minimize pressure on the burn areas and encourage joint mobility, often with the client in a supine or elevated position.
C. "Place a firm pillow under your head." Placing a firm pillow under the head might cause the neck to flex, which could lead to neck contractures. A proper head and neck alignment should be maintained to avoid such complications.
D. "Wear splints on your wrists." Wearing splints on the wrists helps to keep the joints in proper alignment and prevents contractures by maintaining wrist extension. This is an appropriate intervention for clients with upper body burns to promote healing and function.
