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 child who weighs 66 pounds receives a prescription for amoxicillin 80 mg/kg/day by mouth in divided doses every 12 hours. The bottle is labeled, 'Amoxicillin for Oral Suspension, USP 400 mg per 5 mL.' How many mL should the nurse administer with each dose?(Enter numerical value only.)
Correct Answer: 15
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 total daily dose of amoxicillin in mg by multiplying the weight in kg by the dosage in mg/kg/day. Divide the total daily dose of amoxicillin in mg by the number of doses per day to get the dose per administration. Divide the dose per administration in mg by the concentration of amoxicillin in mg/mL. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (66) / (2.2) = 30 kg. (total daily dose in mg) = (80) x (30) = 2400 mg. (dose per administration in mg) = (2400) / (2) = 1200 mg. (volume per administration in mL) = (1200) / (400 / 5) = 15 mL. (rounded volume per administration in mL) = 15 mL. Therefore, the nurse should administer 15 mL of amoxicillin oral suspension with each dose.
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 is initiating a prescription for Dextrose 2.5% in 0.45% Sodium Chloride (D2.5W, 0.45% NS) at 45 mL/hour for a child with dehydration. The nurse attaches a volume-control administration set with a microdrip chamber to the bag of solution. How many microdrops/minute should the nurse regulate the infusion? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 45
Rationale: To find the answer, we can use the following formula: (microdrops/minute) = (mL/hour) x (microdrops/mL) / 60. Substituting the given values, we get: (microdrops/minute) = (45) x (60) / 60. Simplifying, we get: (microdrops/minute) = 45. Therefore, the nurse should regulate the infusion to deliver 45 microdrops/minute of Dextrose 2.5% in 0.45% Sodium Chloride.
A patient is receiving a 200 mL bolus of 0.9% normal saline (NS) to be infused over 20 minutes. The nurse should set the infusion pump to deliver how many mL/hour?(Enter numeric value only.)
Correct Answer: 600
Rationale: The correct answer is 600 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) = (200 / 20) x 60. Simplifying, we get: (mL/hour) = 10 x 60. (mL/hour) = 600. Therefore, the nurse should set the infusion pump to deliver 600 mL/hour of 0.9% NS to the patient.
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.
