A nurse is preparing to administer dextrose 5% in lactated Ringer’s 2 L IV to infuse over 12 hr.
The drop factor on the manual IV tubing is 20 gtt/mL. The nurse should set the IV flow rate 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.)
The Correct Answer is ["56"]
To calculate the IV flow rate, use the formula: gtt/min = (volume in mL x drop factor in gtt/mL) / time in min
Plug in the given values: gtt/min = (2000 mL x 20 gtt/mL) / 720 min
Simplify and solve: gtt/min = 40000 gtt / 720 min
Divide both sides by 10: gtt/min = 4000 gtt / 72 min
Divide both sides by 4: gtt/min = 1000 gtt / 18 min
Divide both sides by 5: gtt/min = 200 gtt / 3.6 min
Divide both sides by 2: gtt/min = 100 gtt / 1.8 min
The answer is approximately 55.6 gtt/min, so round it to the nearest whole number: 56 gtt/min

Correct Answer is ["1.9"]
Explanation
Calculate the dose of naloxone in micrograms: 10 mcg/kg x 75 kg = 750 mcg
Convert the dose of naloxone from micrograms to milligrams: 750 mcg / 1000 = 0.75 mg
Calculate the volume of naloxone in milliliters: 0.75 mg / 0.4 mg/mL = 1.875 mL
Round the answer to the nearest tenth: 1.9 mL
The nurse should administer 1.9 mL of naloxone IM to the client.
Correct Answer is ["0.71"]
Explanation
To calculate the dose of ceftriaxone, use the formula: Dose (mg) / Concentration (mg/mL)
= Volume (mL)
Plug in the values from the question: 250 mg / 350 mg/mL = 0.714 mL
Round the answer to the nearest hundredth: 0.71 mL
The nurse should administer 0.71 mL of the reconstituted medication IM to the client.
