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 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.
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.
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.
A client with a gram-positive bacterial skin infection is receiving daptomycin 500 mg IV every 24 hours. The pharmacy delivers a secondary infusion of 0.9% Sodium Chloride with daptomycin 500 mg/100 mL to be infused in 30 minutes. How many mL/hour should the nurse program the infusion pump?(Enter the numerical value only.)
Correct Answer: 200
Rationale: The correct answer is 200 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) = (100 / 30) x 60. Simplifying, we get: (mL/hour) = 3.333 x 60. (mL/hour) = 200. Therefore, the nurse should program the infusion pump to deliver 200 mL/hour of daptomycin in 0.9% Sodium Chloride.
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.
