Question 1 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: B
Rationale: From 0330 to 0600 is 2.5 hours; 120 mL/hr × 2.5 hr = 300 mL.
Question 2 of 5
A nurse is reviewing the medical record of a client and identifies a serum potassium 6.8 mEq/L (3.5-5 mEq/L). Which of the following medications should the nurse expect to administer?
Correct Answer: C
Rationale: Sodium polystyrene (Kayexalate) treats hyperkalemia by exchanging sodium for potassium in the intestines, promoting potassium elimination, suitable for a dangerously high potassium level of 6.8 mEq/L.

Question 4 of 5
A nurse is collecting data from a client who has a sodium level of 128 mEq/L (136-145 mEq/L) Which of the following manifestations should the nurse expect?
Correct Answer: D
Rationale: Hyponatremia causes cellular swelling in the brain, leading to headaches and other neurological symptoms.
Question 5 of 5
A nurse is preparing to administer dextrose 5% in water (DSW) 100 mL to infuse over 1 hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number.)
Correct Answer: B
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 100 mL / 60 min × 15 gtt/mL = 25 gtt/min.
