The healthcare provider prescribes streptomycin 200 mg intramuscularly every 12 hours. The vial is labeled, 'Streptomycin 1 gram/2.5 mL.' How many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.5
Rationale: The correct answer is 0.5 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) = (200) / (1000 / 2.5). Simplifying, we get: (mL to be administered) = (200) x (2.5 / 1000). (mL to be administered) = 0.5. Therefore, the nurse should administer 0.5 mL of streptomycin from the vial to the client.

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.
A client receives a prescription for 1 liter of lactated Ringer's intravenously (IV) to be infused over 8 hours. The IV administration set delivers 20 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: 42
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) = (1000 / 8) x (20) / 60. Simplifying, we get: (gtt/min) = 125 x 20 / 60. (gtt/min) = 41.667. (rounded gtt/min) = 42. Therefore, the nurse should regulate the infusion to deliver 42 gtt/minute of lactated Ringer's.
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 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.
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.
