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 enoxaparin 1 mg/kg subcutaneously every 12 hours for a client who weighs 132 pounds. The medication is available in 60 mg/0.6 mL prefilled syringe. How many mL should the nurse administer per day?(Enter numerical value only.)
Correct Answer: 1.2
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. Calculate the dose of enoxaparin in mg per administration by multiplying the weight in kg by the dosage in mg/kg. Divide the dose in mg per administration by the concentration of enoxaparin in the prefilled syringe in mg/mL. Multiply the volume in mL per administration by the number of administrations per day. Round the result to the nearest tenth. Using these steps, we get: (weight in kg) = (132) / (2.2) = 60 kg. (dose in mg per administration) = (1) x (60) = 60 mg. (volume in mL per administration) = (60) / (60 / 0.6) = 0.6 mL. (volume in mL per day) = (0.6) x (2) = 1.2 mL. (rounded volume in mL per day) = 1.2 mL. Therefore, the nurse should administer 1.2 mL of enoxaparin per day.
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.
The nurse is caring for a client with an oral temperature of 100.6 F. What temperature in Celsius should the nurse document in the medical record? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 38.1
Rationale: To find the answer, we can use the following formula: (Celsius) = (Fahrenheit - 32) x (5 / 9). Substituting the given value, we get: (Celsius) = (100.6 - 32) x (5 / 9). Simplifying, we get: (Celsius) = 68.6 x (5 / 9). (Celsius) = 38.111. (rounded Celsius) = 38.1. Therefore, the nurse should document the oral temperature as 38.1 C in the medical record.
A patient receives a prescription for warfarin 2 mg IM daily. The pharmacy delivers a vial labeled, warfarin 5 mg/single-use vial. The instructions read, reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL. How many mL should the nurse administer?(Enter the numerical value only.)
Correct Answer: 1
Rationale: First, we need to find out how many mg of warfarin are in one vial. Since the vial is labeled 5 mg/single-use, we can assume that it contains 5 mg of warfarin. Next, we need to find out how many mL of solution are in one vial. Since the instructions say to reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL, we can use the following formula: Amount of solution = amount of water + amount of warfarin. Substituting the given values, we get: Amount of solution = 2.7 + 5 = 7.7 mL. Now, we need to find out how many mL of solution contain 2 mg of warfarin, which is the prescribed dose for the patient. We can use the following formula: mL of solution = mg of warfarin / concentration of warfarin. Substituting the given values, we get: mL of solution = 2 / 2 = 1 mL. Therefore, the nurse should administer 1 mL of solution to the patient.
A client receives a prescription for ganciclovir 375 mg intravenously (IV) every 12 hours to infuse over 90 minutes. The pharmacy delivers ganciclovir 375 mg in a 150 mL IV bag. How many mL/hour should the nurse program the infusion pump?(Enter a whole number only.)
Correct Answer: 100
Rationale: The correct answer is 100 mL/hour. To find the answer, we can use the following formula: (mL/hour) = (mL/minute) x 60. Substituting the given values, we get: (mL/hour) = (150 / 90) x 60. Simplifying, we get: (mL/hour) = 1.667 x 60. (mL/hour) = 100. Therefore, the nurse should program the infusion pump to deliver 100 mL/hour of ganciclovir in IV bag.
