A patient is receiving a secondary infusion of vancomycin 1,500 mg in 250 mL to be infused over two hours. The IV administration set delivers 10 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 21
Rationale: To find the answer, we can use the following formula: (gtt/min) = (mL/hour) x (gtt/mL) / 60. Substituting the given values, we get: (gtt/min) = (250 / 2) x (10) / 60. Simplifying, we get: (gtt/min) = 125 x 10 / 60. (gtt/min) = 1250 / 60. (gtt/min) = 20.833. (rounded gtt/min) = 21. Therefore, the nurse should regulate the infusion at 21 gtt/min.

A patient receives a prescription for warfarin 2 mg IM daily. The pharmacy delivers a vial labeled, warfarin 5 mg/single-use vial. The instructions read, reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL. How many mL should the nurse administer?(Enter the numerical value only.)
Correct Answer: 1
Rationale: First, we need to find out how many mg of warfarin are in one vial. Since the vial is labeled 5 mg/single-use, we can assume that it contains 5 mg of warfarin. Next, we need to find out how many mL of solution are in one vial. Since the instructions say to reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL, we can use the following formula: Amount of solution = amount of water + amount of warfarin. Substituting the given values, we get: Amount of solution = 2.7 + 5 = 7.7 mL. Now, we need to find out how many mL of solution contain 2 mg of warfarin, which is the prescribed dose for the patient. We can use the following formula: mL of solution = mg of warfarin / concentration of warfarin. Substituting the given values, we get: mL of solution = 2 / 2 = 1 mL. Therefore, the nurse should administer 1 mL of solution to the patient.
A patient with a renal calculi receives a prescription for an intravenous infusion of 0.9% Sodium chloride Injection, USP 1,000 mL to be infused over 2.5 hours. The nurse should program the infusion pump to deliver how many mL/hour?(Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 400
Rationale: To find the answer, we can use the following formula: (mL/hour) = (mL/minute) x 60. Substituting the given values, we get: (mL/hour) = (1000 / 150) x 60. Simplifying, we get: (mL/hour) = 6.667 x 60. (mL/hour) = 400. Therefore, the nurse should program the infusion pump to deliver 400 mL/hour of 0.9% Sodium chloride Injection, USP to the patient.
The nurse is initiating a prescription for Dextrose 2.5% in 0.45% Sodium Chloride (D2.5W, 0.45% NS) at 45 mL/hour for a child with dehydration. The nurse attaches a volume-control administration set with a microdrip chamber to the bag of solution. How many microdrops/minute should the nurse regulate the infusion? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 45
Rationale: To find the answer, we can use the following formula: (microdrops/minute) = (mL/hour) x (microdrops/mL) / 60. Substituting the given values, we get: (microdrops/minute) = (45) x (60) / 60. Simplifying, we get: (microdrops/minute) = 45. Therefore, the nurse should regulate the infusion to deliver 45 microdrops/minute of Dextrose 2.5% in 0.45% Sodium Chloride.
The healthcare provider prescribes cefazolin 800 mg IM every six hours. The available vial is labeled, 'Cefazolin 1 gram,' and the instructions for reconstitution state, 'For IM use add 2.5 mL sterile water for injection to provide a total volume of 3.0 mL.' After reconstitution, the solution contains how many mg/mL? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 333
Rationale: To find the answer, we can use the following formula: (mg/mL) = (mg of cefazolin) / (mL of solution). Substituting the given values, we get: (mg/mL) = (1000) / (3). Simplifying, we get: (mg/mL) = 333.333. (rounded mg/mL) = 333. Therefore, after reconstitution, the solution contains 333 mg/mL of cefazolin.
The healthcare provider prescribes ganciclovir 375 mg intravenously (IV) every 12 hours to infuse over 90 minutes. The pharmacy delivers ganciclovir 375 mg in a 150 mL IV bag. How many mL/hour should the nurse program the infusion pump?(Enter a whole number only.)
Correct Answer: 100
Rationale: The correct answer is 100 mL/hour. To find the answer, we can use the following formula: (mL/hour) = (mL/minute) x 60. Substituting the given values, we get: (mL/hour) = (150 / 90) x 60. Simplifying, we get: (mL/hour) = 1.667 x 60. (mL/hour) = 100. Therefore, the nurse should program the infusion pump to deliver 100 mL/hour of ganciclovir in IV bag.
