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.

The healthcare provider prescribes streptomycin 200 mg intramuscularly every 12 hours. The vial is labeled, 'Streptomycin 1 gram/2.5 mL.' How many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.5
Rationale: The correct answer is 0.5 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) = (200) / (1000 / 2.5). Simplifying, we get: (mL to be administered) = (200) x (2.5 / 1000). (mL to be administered) = 0.5. Therefore, the nurse should administer 0.5 mL of streptomycin from the vial to the client.
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 patient receives a prescription for hydrocortisone sodium succinate 150 mg intravenously STAT. The powdered medication needs to be reconstituted with 2 mL of bacteriostatic water that will provide a solution of 250 mg/mL. How many mL should the nurse administer?(Enter numerical value only.)
Correct Answer: 0.6
Rationale: 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) = (150) / (250). Simplifying, we get: (mL to be administered) = 0.6. Therefore, the nurse should administer 0.6 mL of hydrocortisone sodium succinate to the patient.
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.
The healthcare provider prescribes lamivudine oral solution 150 mg twice daily for a client who is HIV positive. The available bottle contains 240 mL of lamivudine labeled, '10 mg/mL.' How many mL should the nurse administer in a 24 hour period?(Enter numeric value only.)
Correct Answer: 30
Rationale: The correct answer is 30 mL. To find the answer, we can use the following steps: Calculate the total daily dose of lamivudine in mg by multiplying the dose per administration by the number of administrations. Divide the total daily dose of lamivudine in mg by the concentration of lamivudine in the oral solution in mg/mL. Round the result to the nearest whole number. Using these steps, we get: (total daily dose in mg) = (150) x (2) = 300 mg. (volume to be administered in mL) = (300) / (10) = 30 mL. (rounded volume to be administered in mL) = 30 mL. Therefore, the nurse should administer 30 mL of lamivudine oral solution in a 24 hour period.
