Q & A

  • What is the primary method for determining the appropriate dose for a child within the pediatric population?

    -The most common method for determining the appropriate dose for a child within the pediatric population is weight-based dosing.

  • How to convert a child's weight from pounds to kilograms?

    -To convert a child's weight from pounds to kilograms, you multiply the weight in pounds by the conversion factor of 0.453592 (or divide by 2.2).

  • How to convert a child's weight from pounds and ounces to kilograms?

    -First, convert the ounces to pounds by dividing the number of ounces by 16. Then, add this value to the weight in pounds, and finally, convert the total weight to kilograms using the same conversion factor as before.

  • What is the significance of rounding the child's weight to at least the nearest hundredth?

    -Rounding the child's weight to at least the nearest hundredth is important for accuracy in dosage calculations, as it ensures that the medication dose is appropriate for the child's size and weight.

  • What are the three methods used in the video for weight-based dosage calculation?

    -The three methods used in the video for weight-based dosage calculation are dimensional analysis, ratio and proportion, and the formula method.

  • What is the purpose of the LevelUp RN dosage calculation workbook?

    -The LevelUp RN dosage calculation workbook is designed to help nursing students master dosage calculations by providing various types of dosage calculation problems and demonstrating how to solve them using multiple methods.

  • What is the ordered dose for the patient in the example?

    -The ordered dose for the patient in the example is 30 milligrams per kilogram per day of moxacin, to be administered in equally divided doses every 8 hours.

  • How much will the patient receive per day in milligrams according to the example?

    -According to the example, the patient will receive 7636 milligrams per day.

  • How many milligrams per dose will the patient receive?

    -The patient will receive 2450 milligrams per dose, as the daily dose of 7636 milligrams is divided into three equal doses given every 8 hours.

  • How many milliliters will the patient receive per day according to the example?

    -The patient will receive 30.5 milliliters per day, calculated from the daily dose in milligrams and the concentration of the medication (125 mg in 5 mL).

  • How many milliliters per dose will the patient receive?

    -The patient will receive 10.2 milliliters per dose, as the daily amount of 30.5 mL is divided by the three times a day dosing regimen.

  • What rounding rule was followed in the medication dosage calculations?

    -All answers in the medication dosage calculations were rounded to the nearest 10, as per the instructions given in the problem.

📈 Converting Weight and Calculating Dosage

In this paragraph, Kathy explains the process of converting a child's weight from pounds to kilograms, emphasizing the need to round to the nearest hundredth for the pediatric population. She provides two examples of weight conversion, one for a child weighing 71 pounds and another for a newborn weighing 7 pounds and 6 ounces. Following this, Kathy discusses a specific dosage calculation scenario involving a patient weighing 56 pounds who requires moxacin. She outlines the steps to calculate the total daily dosage and the dosage per administration, rounding all answers to the nearest ten.

10:03
💊 Determining Dosage Forms and Administration

The final paragraph focuses on calculating the dosage forms and administration for the patient mentioned in the previous section. Kathy demonstrates how to find out how many milliliters the patient will receive per day and per dose, using the same three methods as before: dimensional analysis, ratio and proportion, and the formula method. She applies these methods to the prescribed medication, amoxicillin, which is available in a specific concentration. The paragraph concludes with a call to action for viewers to subscribe to the channel, share the video with classmates and friends in nursing school, and engage with the content by liking the video if they found it helpful.

Keywords
💡Pediatric Dosage Calculation
Pediatric Dosage Calculation refers to the method of determining the appropriate amount of medication for a child based on their weight. In the video, this concept is central as the speaker works through a problem involving weight-based dosing, which is the most common method for pediatric medication administration. The process involves converting the child's weight from pounds to kilograms and then applying the dosage per kilogram as per the medication order.
💡Weight Conversion
Weight Conversion is the process of changing a weight measurement from one unit to another, such as from pounds to kilograms. In the context of the video, it is crucial to accurately convert a child's weight to kilograms to ensure the correct dosage of medication. The speaker reviews how to convert pounds and ounces to kilograms, emphasizing the need to round to the nearest hundredth for precision.
💡Dimensional Analysis
Dimensional Analysis is a method used in mathematics and science to convert between different units of measurement by multiplying the given value by a conversion factor. In the video, the speaker uses this method to convert the child's weight from pounds to kilograms and to calculate the dosage of medication. It simplifies the calculation process by allowing direct conversion of units and is preferred for its efficiency.
💡Ratio and Proportion
Ratio and Proportion is a mathematical concept used to compare two quantities and find an unknown value based on a known relationship. In the video, the speaker uses this method to calculate the dosage of medication for a child by setting up a ratio of the known dosage per kilogram to the child's weight in kilograms. It helps to establish a direct relationship between the dosage and the patient's weight.
💡Formula Method
The Formula Method is a systematic approach to solving problems by using a mathematical formula. In the context of the video, it is one of the methods used to calculate the volume of medication in milliliters that a patient needs to receive based on the dosage in milligrams and the concentration of the medication. This method is a structured way to organize the known values and solve for the unknown quantity.
💡Moxacin
Moxacin is an antibiotic medication mentioned in the video that is used as an example for the dosage calculation problem. The medication order is for 30 milligrams per kilogram per day, to be administered in equally divided doses every 8 hours.
