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.

The healthcare provider prescribes metoclopramide 7.5 mg/mL IM every 3 hours PRN vomiting for a client who is receiving chemotherapy. The nurse prepares an injection using a 2 mL prefilled syringe cartridge labeled, 'metoclopramide 5 mg/mL.' How many mL should the nurse administer?(Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 1.5
Rationale: The correct answer is 1.5 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) = (7.5) / (5). Simplifying, we get: (mL to be administered) = 1.5. Therefore, the nurse should administer 1.5 mL of metoclopramide from the prefilled syringe cartridge to the client.
The healthcare provider prescribes enoxaparin 1 mg/kg subcutaneously every 12 hours for a client who weighs 132 pounds. The medication is available in 60 mg/0.6 mL prefilled syringe. How many mL should the nurse administer per day?(Enter numerical value only.)
Correct Answer: 1.2
Rationale: To find the answer, we can use the following steps: Convert the client's weight from pounds to kilograms by dividing by 2.2. Calculate the dose of enoxaparin in mg per administration by multiplying the weight in kg by the dosage in mg/kg. Divide the dose in mg per administration by the concentration of enoxaparin in the prefilled syringe in mg/mL. Multiply the volume in mL per administration by the number of administrations per day. Round the result to the nearest tenth. Using these steps, we get: (weight in kg) = (132) / (2.2) = 60 kg. (dose in mg per administration) = (1) x (60) = 60 mg. (volume in mL per administration) = (60) / (60 / 0.6) = 0.6 mL. (volume in mL per day) = (0.6) x (2) = 1.2 mL. (rounded volume in mL per day) = 1.2 mL. Therefore, the nurse should administer 1.2 mL of enoxaparin per day.
The healthcare provider prescribes an IV bolus of diltiazem 0.25 mg/kg for a client with atrial fibrillation. The client weighs 178 pounds. How many mg should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 20
Rationale: The correct answer is 20 mg. To find the answer, we can use the following steps: Convert the client's weight from pounds to kilograms by dividing by 2.2. Multiply the weight in kilograms by the dosage in mg/kg. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (178) / (2.2) = 80.909 kg. (dose in mg) = (0.25) x (80.909) = 20.227 mg. (rounded dose in mg) = 20 mg. Therefore, the nurse should administer 20 mg of IV diltiazem to the client.
The healthcare provider prescribes amoxicillin 500 mg every 8 hours for a child who weighs 88 pounds. The recommended maximum safe dose is 50 mg/kg/24 hour. The available suspension is labeled, 'Amoxicillin Suspension 250 mg/5 mL.' Based on this child's weight, how many mL should the nurse administer?(Enter numerical value only. If rounding is required, round to the whole number.)
Correct Answer: 10
Rationale: To find the answer, we can use the following steps: Convert the child's weight from pounds to kilograms by dividing by 2.2. Calculate the volume of amoxicillin suspension in mL by dividing the dose in mg by the concentration in mg/mL. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (88) / (2.2) = 40 kg. (volume in mL) = (500) / (250 / 5) = 10 mL. (rounded volume in mL) = 10 mL. Therefore, the nurse should administer 10 mL of amoxicillin suspension to the child.
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.
