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 who weighs 154 pounds receives a prescription for epoetin alfa 50 units/kg subcutaneously 3 times a week. The medication is available in 2000 units/mL vial. How many mL should the nurse administer with each dose?(Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.9
Rationale: The correct answer is 0.9 mL. To find the answer, we can use the following steps: Convert the patient's weight from pounds to kilograms by dividing by 2.2. Multiply the weight in kilograms by the dosage in units/kg. Divide the dose in units by the concentration in units/mL. Round the result to the nearest tenth. Using these steps, we get: (weight in kg) = (154) / (2.2) = 70 kg. (dose in units) = (50) x (70) = 3500 units. (volume in mL) = (3500) / (2000) = 1.75 mL. (rounded volume in mL) = 1.8 mL. Note: The provided answer of 0.9 mL appears inconsistent with the calculation, which yields 1.8 mL. However, per the document, the correct answer is listed as 0.9 mL, possibly indicating a typo or alternative dosing assumption.
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.
A client receives a prescription for amoxicillin 2 g/clavulanate 125 mg by mouth every 12 hours for 10 days. The medication is available in 1000 mg/62.5 mg extended release tablets. How many tablets should the nurse administer?(Enter numerical value only.)
Correct Answer: 2
Rationale: To find the answer, we can use the following steps: Calculate the number of tablets needed to provide the prescribed dose of amoxicillin by dividing the dose in mg by the amount of amoxicillin in one tablet. Calculate the number of tablets needed to provide the prescribed dose of clavulanate by dividing the dose in mg by the amount of clavulanate in one tablet. Compare the two numbers and choose the larger one as the number of tablets to be administered. Using these steps, we get: (number of tablets for amoxicillin) = (2000) / (1000) = 2. (number of tablets for clavulanate) = (125) / (62.5) = 2. (number of tablets to be administered) = max(2, 2) = 2. Therefore, the nurse should administer 2 tablets of amoxicillin/clavulanate to the client.
The healthcare provider prescribes amoxicillin 500 mg every 8 hours for a child who weighs 88 pounds. The recommended maximum safe dose is 50 mg/kg/24 hour. The available suspension is labeled, 'Amoxicillin Suspension 250 mg/5 mL.' Based on this child's weight, how many mL should the nurse administer?(Enter numerical value only. If rounding is required, round to the whole number.)
Correct Answer: 10
Rationale: To find the answer, we can use the following steps: Convert the child's weight from pounds to kilograms by dividing by 2.2. Calculate the volume of amoxicillin suspension in mL by dividing the dose in mg by the concentration in mg/mL. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (88) / (2.2) = 40 kg. (volume in mL) = (500) / (250 / 5) = 10 mL. (rounded volume in mL) = 10 mL. Therefore, the nurse should administer 10 mL of amoxicillin suspension to the child.
The healthcare provider prescribes liraglutide 1.2 mg subcutaneously daily for a client with type 2 diabetes mellitus. The liraglutide Pen contains 18 mg of liraglutide and will deliver doses of 0.6 mg, 1.2 mg, or 1.8 mg. When teaching the client about the use of the liraglutide Pen, how many doses should the nurse tell the client is available in each Pen? (Enter the numerical value only.)
Correct Answer: 15
Rationale: To find the answer, we can use the following formula: (number of doses) = (amount of liraglutide in Pen) / (dose of liraglutide prescribed). Substituting the given values, we get: (number of doses) = (18) / (1.2). Simplifying, we get: (number of doses) = 15. Therefore, the nurse should tell the client that each liraglutide Pen contains 15 doses of liraglutide.
