Q & A
What is the main focus of the video?
-The main focus of the video is on weight-based medication calculations for nursing professionals.
How is the dosage of medication B calculated for a 95-pound adult patient?
-The dosage of medication B is calculated by using the formula: (1 mg/kg/dose) * (patient's weight in kg). The patient's weight must first be converted from pounds to kilograms by dividing by 2.2. For a 95-pound patient, the calculation would be (1 mg/kg) * (95 lb / 2.2 lb/kg), resulting in approximately 43.2 mg per dose.
What is the formula for converting pounds to kilograms?
-The formula for converting pounds to kilograms is 1 kilogram = 2.2 pounds, or lb/kg = 2.2.
How much medication A should be given to a patient weighing 185 pounds?
-For a patient weighing 185 pounds, the dosage of medication A is calculated as follows: (1 mg/kg/dose) * (185 lb / 2.2 lb/kg), which equals 84.1 mg per dose.
How many milliliters of medication C should be administered to a 28-pound child?
-For a 28-pound child, the nurse should administer a dosage of medication C based on the formula: (10 mg/kg/dose) * (child's weight in kg) / (120 mg/5 ml). After converting the child's weight from pounds to kilograms and performing the calculation, the nurse should administer approximately 5.3 ml per dose.
What is the difference between the dosage calculation for medication M compared to the previous medications?
-The dosage calculation for medication M is different because it specifies milligrams per kilogram per day, rather than per dose. The nurse must first calculate the total daily dosage and then divide it by the number of doses given per day (which is 2 in this case, every 12 hours) to find the dosage per dose.
How many doses are given per day for medication M?
-For medication M, which is administered every 12 hours, there are 2 doses given per day.
What is the final dosage per dose for medication M?
-The final dosage per dose for medication M is 675 milligrams, after calculating the total daily dosage and dividing it by 2 (the number of doses per day).
Why is it important to include the unit of measurement in the numerator or denominator when setting up the calculation?
-Including the unit of measurement in the numerator or denominator is important because it helps to ensure the correct conversion and canceling out of units, leading to the correct answer in the desired unit, such as milligrams per dose.
How does the nurse determine the dosage for a child when the medication's concentration is given in a different unit?
-The nurse determines the dosage for a child by first identifying the required dosage per kilogram and then converting the child's weight into kilograms. They also need to convert the medication's concentration to the same unit as the dosage requirement, before performing the calculation.
What should a nurse do if the script does not specify whether to round the dosage?
-If the script does not specify whether to round the dosage, the nurse should follow the institution's policies or consult with a pharmacist or physician for guidance on rounding practices.
Outlines
📚 Medication Dosage Calculation for Adults
This paragraph focuses on calculating medication dosages based on weight for adult patients. The nursing professor introduces a practice scenario where a nurse prepares medication B for an adult patient with a prescription of 1 milligram per kilogram every 12 hours. The patient weighs 95 pounds, and the calculation involves converting the weight from pounds to kilograms using the conversion factor of 2.2 pounds per kilogram. The goal is to find out the number of milligrams to administer per dose. The calculation is demonstrated step by step, leading to a final answer of 43.2 milligrams per dose, depending on whether rounding is required. Another example involves a patient weighing 185 pounds and receiving medication A, resulting in an 84.1 milligram dose. The third example concerns a child with medication C, weighing 28 pounds, and the calculation results in a 5.3 ml dose. The paragraph concludes with a different scenario involving medication M, where the dosage is based on milligrams per kilogram per day, and the challenge is to determine the dosage per dose rather than per day.
📝 Dosage Calculation for Weight-Based Medication in Children
The second paragraph delves into the specifics of calculating medication dosages for children, using a different approach from the previous adult-focused examples. It presents a scenario where a nurse administers medication M to a patient weighing 198 pounds, with a prescription of 15 milligrams per kilogram per day. The calculation starts by converting the patient's weight to kilograms and then determining the total daily dosage. The challenge here is to find out how much medication should be given per dose, considering the medication is divided every 12 hours. The calculation involves dividing the total daily dosage by the number of doses given in a day (two doses), resulting in a 675-milligram dose per administration. This paragraph emphasizes the importance of understanding the difference between calculating dosages per day versus per dose, which is crucial for accurate medication administration.
