Extract:
Question 1 of 5
The nurse is caring for a group of patients. Which patient is at highest risk for hypovolemia?
Correct Answer: A
Rationale: Significant blood loss (2 liters) during surgery poses the highest risk for hypovolemia, requiring immediate fluid replacement.
Question 2 of 5
The IV infusion pump for a patient receiving an IV therapy begins to alarm and displays occlusion. When the silence button is pushed, the alarm quickly resumes. Which action should the nurse take first?
Correct Answer: D
Rationale: Checking for kinking of the tubing or a closed clamp is the first action, as most occlusions are due to these issues, which can often be resolved immediately.
Question 3 of 5
Which is the most reliable method for monitoring improvement when restoring fluid balance?
Correct Answer: D
Rationale: Daily weights directly reflect changes in fluid retention or loss, providing the most reliable measure of fluid balance.
Question 4 of 5
A nurse is assisting with care of a client who has a prescription for 3,000 mL of intravenous fluids over the next 24 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number)
Correct Answer: B
Rationale: Dividing total volume by time, 3000 mL / 24 hr = 125 mL/hr.
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.
