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.

A client who weighs 60 kg receives a prescription for dalteparin 200 units/kg subcutaneously once a day for a month. The medication is available in 25,000 units/mL vial. How many mL should the nurse administer?(Enter numerical value. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.5
Rationale: To find the answer, we can use the following steps: Calculate the dose of dalteparin in units by multiplying the weight in kg by the dosage in units/kg. Divide the dose in units by the concentration in units/mL. Round the result to the nearest tenth. Using these steps, we get: (dose in units) = (60) x (200) = 12,000 units. (volume in mL) = (12,000) / (25,000) = 0.48 mL. (rounded volume in mL) = 0.5 mL. Therefore, the nurse should administer 0.5 mL of dalteparin from the vial to the client.
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 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.

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.
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.
