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.

A patient is receiving a secondary infusion of vancomycin 1,500 mg in 250 mL to be infused over two hours. The IV administration set delivers 10 gtt/mL. How many gtt/min should the nurse regulate the infusion? (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) = (250 / 2) x (10) / 60. Simplifying, we get: (gtt/min) = 125 x 10 / 60. (gtt/min) = 1250 / 60. (gtt/min) = 20.833. (rounded gtt/min) = 21. Therefore, the nurse should regulate the infusion at 21 gtt/min.

A patient is receiving a secondary infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. How many mL/hour should the nurse program the infusion pump?(Enter numerical value only.)

Correct Answer: 250

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) = (500 / 120) x 60. Simplifying, we get: (mL/hour) = 4.167 x 60. (mL/hour) = 250. Therefore, the nurse should program the infusion pump to deliver 250 mL/hour of azithromycin in NS to the patient.

An adult client receives a prescription for diphenhydramine 15 mL by mouth every 12 hours PRN for pruritus. The bottle is labeled, 'diphenhydramine 12.5 mg/5 mL.' What is the total daily dose in mg that the client receives? (Enter numerical value only.)

Correct Answer: 75

Rationale: To find the answer, we can use the following steps: Calculate the dose of diphenhydramine in mg per administration by multiplying the volume in mL by the concentration in mg/mL. Multiply the dose in mg per administration by the number of administrations per day. Round the result to the nearest whole number. Using these steps, we get: (dose in mg per administration) = (15) x (12.5 / 5) = 37.5 mg. (total daily dose in mg) = (37.5) x (2) = 75 mg. (rounded total daily dose in mg) = 75 mg. Therefore, the client receives 75 mg of diphenhydramine per day.

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.

The healthcare provider prescribes a hydration infusion of normal saline to run over 3 hours at 30 mL/kg for a client who is dehydrated and weighs 70 kg. The nurse should program the infusion pump to deliver how many mL/hour?(Enter numeric value only.)

Correct Answer: 700

Rationale: To find the answer, we can use the following steps: Calculate the total volume of normal saline in mL by multiplying the weight in kg by the dosage in mL/kg. Divide the total volume of normal saline in mL by the number of hours to get the rate in mL/hour. Round the result to the nearest whole number. Using these steps, we get: (total volume in mL) = (30) x (70) = 2100 mL. (rate in mL/hour) = (2100) / (3) = 700 mL/hour. (rounded rate in mL/hour) = 700 mL/hour. Therefore, the nurse should program the infusion pump to deliver 700 mL/hour of normal saline.
