The healthcare provider prescribed 2 liters of 5% Dextrose in water (D5W) to infuse in 24 hours. The IV administration set delivers 15 gtt/mL. How many mL/hour should the nurse program the infusion pump? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 83
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) = (2000 / 24) x 60. Simplifying, we get: (mL/hour) = 83.333. (rounded mL/hour) = 83. Therefore, the nurse should program the infusion pump to deliver 83 mL/hour of D5W.

A patient receives a prescription for oxytocin 2 milliunits/min intravenously (IV) for labor augmentation. The IV bag contains oxytocin 20 units in lactated Ringer's 1 liter. How many mL/hour should the nurse program the infusion pump to deliver?(Enter numerical value only.)
Correct Answer: 6
Rationale: To find the answer, we can use the following steps: Convert the dosage of oxytocin from milliunits/min to units/hour by multiplying by 60. Calculate the concentration of oxytocin in the IV bag by dividing the amount of oxytocin by the volume of solution. Divide the dosage of oxytocin by the concentration of oxytocin in the IV bag to get the volume to be delivered. Using these steps, we get: (dosage of oxytocin in units/hour) = (2) x (60) = 120 milliunits/hour. (concentration of oxytocin in IV bag) = (20) / (1000) = 0.02 units/mL. (volume to be delivered in mL/hour) = (120 x 10^-3) / (0.02) = 6 mL/hour. Therefore, the nurse should program the infusion pump to deliver 6 mL/hour of oxytocin in lactated Ringer's to the patient.
The healthcare provider prescribes a hydration infusion of normal saline to run over 3 hours at 30 mL/kg for a client who is dehydrated and weighs 70 kg. The nurse should program the infusion pump to deliver how many mL/hour?(Enter numeric value only.)
Correct Answer: 700
Rationale: To find the answer, we can use the following steps: Calculate the total volume of normal saline in mL by multiplying the weight in kg by the dosage in mL/kg. Divide the total volume of normal saline in mL by the number of hours to get the rate in mL/hour. Round the result to the nearest whole number. Using these steps, we get: (total volume in mL) = (30) x (70) = 2100 mL. (rate in mL/hour) = (2100) / (3) = 700 mL/hour. (rounded rate in mL/hour) = 700 mL/hour. Therefore, the nurse should program the infusion pump to deliver 700 mL/hour of normal saline.
A client receives a prescription for 1 liter of lactated Ringer's intravenously (IV) to be infused over 12 hours. The IV administration set delivers 60 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: 83
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) = (1000 / 12) x (60) / 60. Simplifying, we get: (gtt/min) = 83.333. (rounded gtt/min) = 83. Therefore, the nurse should regulate the infusion to deliver 83 gtt/minute of lactated Ringer's.
The healthcare provider prescribes streptomycin 200 mg intramuscularly every 12 hours. The vial is labeled, 'Streptomycin 1 gram/2.5 mL.' How many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.5
Rationale: The correct answer is 0.5 mL. To find the answer, we can use the following formula: (mL to be administered) = (mg prescribed) / (mg per mL). Substituting the given values, we get: (mL to be administered) = (200) / (1000 / 2.5). Simplifying, we get: (mL to be administered) = (200) x (2.5 / 1000). (mL to be administered) = 0.5. Therefore, the nurse should administer 0.5 mL of streptomycin from the vial to the client.
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.
