Question 1 of 5
The nurse is preparing to administer methylprednisolone 40 mg IV. The medication vial is labeled '125 mg per 2 mL.' How many mL of medication should the nurse administer?(Enter numeric value only. If rounding is required, round to the nearest hundredth.)
Correct Answer: 0.64
Rationale: The correct answer is 0.64 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) = (40) / (125 / 2). Simplifying, we get: (mL to be administered) = (40) x (2 / 125). (mL to be administered) = 0.64.
Therefore, the nurse should administer 0.64 mL of methylprednisolone IV.
Question 2 of 5
The healthcare provider prescribed 2 liters of 5% Dextrose in water (D5W) to infuse in 24 hours. The IV administration set delivers 15 gtt/mL. How many mL/hour should the nurse program the infusion pump? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 83
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) = (2000 / 24) x 60. Simplifying, we get: (mL/hour) = 83.333. (rounded mL/hour) = 83.
Therefore, the nurse should program the infusion pump to deliver 83 mL/hour of D5W.
Question 3 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.
Question 4 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 5 of 5
The nurse plans to provide the next shift with the IV fluid balance for a client who had a 440 mL secondary infusion that was started 2 hours ago at a rate of 85 mL/hour via an infusion pump. What is the remaining volume to be infused? (Enter numeric value only.)
Correct Answer: 270
Rationale:
To find the answer, we can use the following formula: (remaining volume) = (initial volume) - (infused volume). Substituting the given values, we get: (remaining volume) = (440) - ((85 x 2)). Simplifying, we get: (remaining volume) = (440) - (170). (remaining volume) = 270.
Therefore, the remaining volume to be infused is 270 mL.
