Question 1 of 5
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.
Question 2 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 3 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 4 of 5
A patient with deep vein thrombosis (DVT) is receiving a continuous infusion of Heparin Sodium 20,000 Units in 5% Dextrose Injection 500 mL at the rate of 25 mL/hour. How many units of heparin should the client receive in 12 hours? (Enter numeric value only.)
Correct Answer: 1200
Rationale:
To find the answer, we can use the following formula: (units of heparin) = (mL/hour) x (hours) x (units per mL). Substituting the given values, we get: (units of heparin) = (25) x (12) x (20,000 / 500). Simplifying, we get: (units of heparin) = (25) x (12) x (40). (units of heparin) = 1200.
Therefore, the client should receive 1200 units of heparin in 12 hours.
Question 5 of 5
The healthcare provider prescribes heparin 1,400 units/hour intravenously (IV). The IV bag contains heparin 20,000 units in 250 mL dextrose 5% in water. How many mL/hour should the nurse program the infusion pump to deliver?(Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 17
Rationale: The correct answer is 17 mL/hour.
To find the answer, we can use the following formula: (mL/hour) = (units/hour) x (mL per unit). Substituting the given values, we get: (mL/hour) = (1,400) x (250 / 20,000). Simplifying, we get: (mL/hour) = (1,400) x (0.0125). (mL/hour) = 17.5. (rounded mL/hour) = 17.
Therefore, the nurse should program the infusion pump to deliver 17 mL/hour of heparin in dextrose 5% in water.
