Question 2 of 5
At 0330, a nurse is caring for a client who is postoperative. The client's IV fluids are infusing at 120 mL/hr. How many mL of IV fluid should infuse by 0600? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: A
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 120 mL/60 min × 60 gtt/mL = 120 gtt/min.
Question 4 of 5
A nurse is caring for a client whose serum potassium level is 5.3 mEq/L (3.5-5 mEq/L). The nurse should anticipate a prescription for which of the following medications?
