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.

During a home visit, the nurse learns that a client is taking calcium polycarbophil, an over the counter laxative. A single tablet contains 625 mg and the daily maximum dosage is 5 grams in divided doses. How many tablets could the client safely take in one day?(Enter the numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 8
Rationale: The correct answer is 8 tablets. To find the answer, we can use the following steps: Convert the daily maximum dosage from grams to milligrams by multiplying by 1000. Divide the daily maximum dosage in milligrams by the amount of calcium polycarbophil in one tablet. Round the result to the nearest whole number. Using these steps, we get: (daily maximum dosage in mg) = (5) x (1000) = 5000 mg. (number of tablets) = (5000) / (625) = 8 tablets. (rounded number of tablets) = 8. Therefore, the client could safely take up to 8 tablets of calcium polycarbophil in one day.
A client receives a prescription for 1 liter of lactated Ringer's intravenously (IV) to be infused over 12 hours. The IV administration set delivers 60 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: 83
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 / 12) x (60) / 60. Simplifying, we get: (gtt/min) = 83.333. (rounded gtt/min) = 83. Therefore, the nurse should regulate the infusion to deliver 83 gtt/minute of lactated Ringer's.
A 4-year-old is admitted with croup and receives a prescription for a single dose of dexamethasone 0.6 mg/kg IM. The child weighs 35 pounds. How many mg should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest 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. Multiply the weight in kilograms by the dosage in mg/kg. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (35) / (2.2) = 15.909. (dose in mg) = (0.6) x (15.909) = 9.545. (rounded dose in mg) = 10. Therefore, the nurse should administer 10 mg of dexamethasone to the child.
A patient with deep vein thrombosis (DVT) is receiving a continuous infusion of Heparin Sodium 20,000 Units in 5% Dextrose Injection 500 mL at the rate of 25 mL/hour. How many units of heparin should the client receive in 12 hours? (Enter numeric value only.)
Correct Answer: 1200
Rationale: To find the answer, we can use the following formula: (units of heparin) = (mL/hour) x (hours) x (units per mL). Substituting the given values, we get: (units of heparin) = (25) x (12) x (20,000 / 500). Simplifying, we get: (units of heparin) = (25) x (12) x (40). (units of heparin) = 1200. Therefore, the client should receive 1200 units of heparin in 12 hours.
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.
