Study Notes
Drug Delivery and IV Rates
- Drug delivery and intravenous (IV) rates are crucial for administering medications accurately.
- IV rates are calculated using formulas that consider the volume of medication, time of administration, and the drop factor of the IV set.
- Calculations for IV flow rates need the volume (mL), time (minutes or hours), and the drop factor (gtts/mL) set.
- Flow rates are expressed in drops per minute (gtts/min).
- Dosage calculations for various medications, especially those for children, often depend on the patient's weight.
- Dose calculations typically involve converting pounds (lbs) to kilograms (kg).
- Common terms include “amount desired”, “amount on hand”, and “quantity”.
- Several drug types and dosages are noted in the provided text, including Cetirizine, Diphenhydramine, Ibuprofen, and Klor-Con.
- Drug dosage calculations are essential when a physician orders a drug in one dose, while the available drug is in a different dose.
- Formulas are given to enable calculation of drug dosage and drip rates depending on the information provided.
- For certain conditions, it's relevant to note if a rate is measured as a daily, hourly or drop per second value.
- Specific examples include calculating the number of tablets to administer (e.g., Toprol XL, Klor-Con) and determining IV drip rates.
