💡Dosage Calculations

Dosage Calculations refer to the process of determining the correct amount of medication to administer to a patient based on factors such as weight, age, and the medication's concentration. In the video, the speaker goes over various types of dosage calculations, emphasizing the importance of accuracy in healthcare to ensure patient safety and effective treatment.

💡Dimensional Analysis

Dimensional Analysis is a method used in mathematics and science to convert between different units of measurement. It involves setting up a ratio that simplifies the units to a common denominator, allowing for the calculation of an unknown quantity. In the context of the video, dimensional analysis is crucial for solving dosage problems, as it helps nurses convert and compare different units to determine the correct dosage.

💡Metric System

The Metric System is an internationally recognized decimal system of measurement, which is used in many fields including science, medicine, and everyday life. It is based on the meter as the unit of length and the kilogram as the unit of mass. In the video, the metric system is essential for dosage calculations, as it provides the standard units and conversion factors necessary for accurate medication dosing.

💡Nursing

Nursing is a healthcare profession focused on the care, support, and rehabilitation of patients. It involves various tasks, including administering medications, monitoring patient health, and educating patients and their families about health care. In the video, the dosage calculations are specifically relevant to nursing practice, as nurses are often responsible for accurately calculating and administering medications to ensure patient safety and effective treatment.

💡Conversion Factors

Conversion factors are numerical values used to convert a quantity from one unit to another within a system of measurement. They are essential in dosage calculations to ensure that the correct amount of medication is given based on the required units. In the video, conversion factors are used to transition between different units such as ounces to milliliters or milligrams to micrograms.

💡Oral Suspension

Oral Suspension is a type of medication formulation where the active drug particles are suspended in a liquid medium. It is designed for administration through the mouth and is often used for drugs that are not easily soluble in water or for pediatric patients who may have difficulty swallowing solid dosage forms. In the video, the speaker discusses an example of calculating the dosage for an oral suspension, highlighting the importance of understanding medication forms in dosage calculations.

💡IV Bolus

IV Bolus refers to the rapid administration of a medication directly into the bloodstream through an intravenous (IV) line. This method is used for medications that require immediate effect or when a precise control over the rate of drug delivery is needed. In the video, the speaker explains how to calculate the volume of an IV bolus based on the ordered dosage and the concentration of the medication in the vial.

💡IV Flow Rate

IV Flow Rate refers to the speed at which a medication or solution is administered into a patient's bloodstream via an intravenous (IV) line. It is typically measured in milliliters per hour or drops per minute and is crucial for maintaining the correct dosage and therapeutic effect of the medication. In the video, the speaker covers various problems related to calculating IV flow rates, taking into account different scenarios and health orders.
