Question 1 of 5
A nurse is preparing to administer 400 mL of 0.9% sodium chloride IV over 8 hr. The drop factor of the manual IV tubing is 60 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (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: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 400 mL / (8 × 60) × 60 gtt/mL = 50 gtt/min.
Question 2 of 5
A nurse is collecting data from a client who has a calcium level of 8 mg/dL (9.0-10.5 mg/dL). Which of the following manifestations should the nurse expect?
Correct Answer: D
Rationale: Tetany, involving muscle cramps and spasms, is a common manifestation of hypocalcemia due to increased neuromuscular excitability at low calcium levels.
Question 3 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.
