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.

A 4-year-old is admitted with croup and receives a prescription for a single dose of dexamethasone 0.6 mg/kg IM. The child weighs 35 pounds. How many mg should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest 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. 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) = (35) / (2.2) = 15.909. (dose in mg) = (0.6) x (15.909) = 9.545. (rounded dose in mg) = 10. Therefore, the nurse should administer 10 mg of dexamethasone to the child.
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.
A client with human immunodeficiency virus (HIV) begins active labor at 38 weeks gestation and receives a prescription for zidovudine 2 mg/kg IV, to be administered over 1 hour. The client weighs 185 lbs. Based on the client's weight, how many mg should the nurse prepare to administer? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 168
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. 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) = (185) / (2.2) = 84.091 kg. (dose in mg) = (2) x (84.091) = 168.182 mg. (rounded dose in mg) = 168 mg. Therefore, the nurse should prepare to administer 168 mg of zidovudine IV to the client.
The nurse is preparing to administer methylprednisolone 40 mg IV. The medication vial is labeled '125 mg per 2 mL.' How many mL of medication should the nurse administer?(Enter numeric value only. If rounding is required, round to the nearest hundredth.)
Correct Answer: 0.64
Rationale: The correct answer is 0.64 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) = (40) / (125 / 2). Simplifying, we get: (mL to be administered) = (40) x (2 / 125). (mL to be administered) = 0.64. Therefore, the nurse should administer 0.64 mL of methylprednisolone IV.
During a home visit, the nurse learns that a client is taking calcium polycarbophil, an over the counter laxative. A single tablet contains 625 mg and the daily maximum dosage is 5 grams in divided doses. How many tablets could the client safely take in one day?(Enter the numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 8
Rationale: The correct answer is 8 tablets. To find the answer, we can use the following steps: Convert the daily maximum dosage from grams to milligrams by multiplying by 1000. Divide the daily maximum dosage in milligrams by the amount of calcium polycarbophil in one tablet. Round the result to the nearest whole number. Using these steps, we get: (daily maximum dosage in mg) = (5) x (1000) = 5000 mg. (number of tablets) = (5000) / (625) = 8 tablets. (rounded number of tablets) = 8. Therefore, the client could safely take up to 8 tablets of calcium polycarbophil in one day.
