for the client. In practice, this guides the nurse to set priorities and protect the client from harm. Safety,
nutrition, and clear communication are frequent priorities.

A. for the first 8 hours.
B. 7,000 mL
C. 3,500 mL
D. 10,500 mL
Answer: B
Rationale: Total fluid = 4mL * 70kg * 50 = 14,000 mL for 24 hours. The first half (7,000 mL) must be
given in the first 8 hours. This is important because the nurse must choose the action that keeps the
client safest while still meeting their basic needs. Always think about safety first when answering these
