Intermediate / Tina Jones Med Math Questions 1. Problem type: Total daily dose calculation Medication: Oxycodone @ hospital Suppose Ms. Jones reports a pain rating greater than 4. For this pain rating, the prescriber’s order allows oxycodone, 5 mg, 1 tab, by mouth, every 4 hrs. Assume that for her first day of hospitalization, she takes all available doses in 24 hours. How many mg of oxycodonewill she have ingested? HINT Multiply the number of doses Ms. Jones would take in a single day by the number of tablets taken. SAMPLE SOLUTION 1. Determine how many doses Ms. Jones would take in 24 hours. 24 hours x 1 dose = 6 doses 4 hours 2. Multiply the number of doses by the number of milligrams per dose of oxycodone. 6 doses x 5 mg = 30 mg 1 dose ANSWER Number: 30 Units: mg 2. Problem type: Total daily dose calculation Medication: Oxycodone @ hospital Suppose Ms. Jones reports a pain rating greater than 4. For this pain rating, the prescriber’s order allows oxycodone, 5 mg, 1 tab, by mouth, every 4 hrs. Assume that on her second day of hospitalization, Ms. Jones only reports a pain rating greater than 4 two times. How many mg of oxycodonewill she have ingested? HINT Multiply the number of doses that Ms. Jones took by the number of tablets. SAMPLE SOLUTION 1. Multiply the dosage by the number of tablets per dose. 2 doses x 1 tablet = 2 tablets 1 dose 3. Multiply the dosage of oxycodone by the number of tablets. 2 tablets x 5 mg = 10 mg 1 tablet ANSWER Number: 10 Units: mg 3. Problem type: Dosage calculation + weightbased dosage Medication: Promethazine @ hospital hypothetical Children older than 2 can be administered promethazine rectally as an antihistamine, at a dosage of 0.125 mg/kg every 4 to 6 hours. Assume you were administering this to a child who weighed 27.5 lbs. How much promethazineshould this child be administered at one time? Round your answer to hundredths. HINT Convert pounds to kilograms, and multiply the weight by the dosage. SAMPLE SOLUTION 1. Convert pounds (lbs) to kilograms (kg). 27.5 lbs x 1 kg = 12.5 kg 2.20 lb 2. Multiply dosage by the number of kilograms. 0.125 mg x 12.5 kg = 1.56 mg kg ANSWER Number: 1.56 Units: mg 4. Problem type: Total daily dose calculation Medication: Albuterol @ hospital Ms. Jones’ orders include albuterol, 2 puffs every 4 hours as needed for wheezing. The dosage of the albuterol is 90 mcg/spray. Assume she takes the ordered amount of her inhaler two times in a single day. How many mcg of albuterol will she have been administered on that day? HINT Multiply the number of doses by the number of sprays per dose. Then, multiply the number of sprays by the dosage per spray. SAMPLE SOLUTION 1. Multiply the number of doses by the number of sprays per dose. 2 doses x 2 sprays = 4 total sprays 1 dose 3. Multiply the dosage per spray by the number of sprays. 4 sprays x 90 mcg = 360 mcg 1 spray ANSWER Number: 360 Units: mcg
