Question 1 of 5
A client is brought to the emergency center for fluid replacement after running a marathon, and the healthcare provider prescribes a 500 mL bolus of 0.9% normal saline to be administered over 4 hours. The infusion set delivers 10 gtt/mL, so the nurse should regulate the infusion to deliver how many gtt/minute? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 21
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) = (500 / 4) x (10) / 60. Simplifying, we get: (gtt/min) = 125 x 10 / 60. (gtt/min) = 20.833. (rounded gtt/min) = 21.
Therefore, the nurse should regulate the infusion to deliver 21 gtt/minute of 0.9% normal saline.
Question 2 of 5
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.
Question 3 of 5
The nurse plans to administer a bolus dose of IV Heparin based on the client's weight. The prescribed bolus dose is 100 units/kg. The client weighs 198 pounds. How many units of Heparin should the nurse administer? (Enter numeric value only.)
Correct Answer: 9000
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 units/kg. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (198) / (2.2) = 90 kg. (dose in units) = (100) x (90) = 9000 units. (rounded dose in units) = 9000 units.
Therefore, the nurse should administer 9000 units of IV Heparin to the client.
Question 4 of 5
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.
Question 5 of 5
Filgrastim 5 mcg/kg/day subcutaneous is prescribed for a child with cancer who weighs 88 pounds. The medication is labeled 300 mcg/mL. How many mL should the nurse administer daily to this child?(Enter the numerical value only. If rounding required, round to the nearest tenth.)
Correct Answer: 0.7
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 dose of filgrastim in mcg by multiplying the weight in kg by the dosage in mcg/kg/day. Divide the dose in mcg by the concentration of filgrastim in mcg/mL. Round the result to the nearest tenth. Using these steps, we get: (weight in kg) = (88) / (2.2) = 40 kg. (dose in mcg) = (5) x (40) = 200 mcg. (volume in mL) = (200) / (300) = 0.667 mL. (rounded volume in mL) = 0.7 mL.
Therefore, the nurse should administer 0.7 mL of filgrastim to this child daily.
