Question 1 of 5
A nurse is preparing to administer lactated Ringer's solution IV to infuse at 120 mL/hr for a client who has a respiratory disorder. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min?(Round to the nearest whole number.)
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 2 of 5
A nurse is preparing to administer dextrose 5% in water IV to infuse at 100 mL/60 min. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min? (Round to the nearest whole number.)
Correct Answer: A
Rationale: Using the formula Flow rate (gtt/min) = (Volume/Time) × Drop factor, 100 mL/60 min × 60 gtt/mL = 100 gtt/min.
Question 3 of 5
The nurse is preparing to start an IV on a newly admitted patient. Which action by the nurse places the patient at risk for infection?
Correct Answer: C
Rationale: Blowing on the cleansed area introduces bacteria from the nurse's breath, increasing infection risk.
Question 4 of 5
A nurse is monitoring a client who is dehydrated. Which of the following laboratory findings should the nurse report to the provider?
Correct Answer: C
Rationale: An elevated BUN level (25 mg/dL) is above the normal range (10-20 mg/dL) and indicates dehydration due to increased protein breakdown and decreased renal perfusion, requiring immediate reporting to the provider.
Question 5 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.
