Final answer:
Dosage calculations in medicine require precision in converting measurement units and understanding prescription instructions. Professionals must accurately calculate the necessary amount of medication, such as determining that 0.225 mg of a prescription equals 3 tablets of 75 µg each, or that 1.5 liters of a liquid mixture is the sum of its parts. These calculations ensure effective and safe patient treatment.
Step-by-step explanation:
When calculating the dosage of a prescription, particularly in a medical or pharmaceutical context, precision is crucial. In this case, the question involves determining whether medication should be given as 0.75 ml without additional context. However, if we analyze some given examples, we can understand the process involved in dosage calculation. For instance, if a prescription indicates a dosage of 0.225 mg of Synthroid, and the available tablets contain 75 µg each, one must first convert the dosage into micrograms (µg), since 1 mg equals 1000 µg. Thus, 0.225 mg equals 225 µg. By dividing the prescribed 225 µg by the concentration of each tablet, which is 75 µg, we find that 3 tablets are required for the daily dose.
Another context where dosage calculations are important is in preparing mixtures, such as cough syrup. When a pharmacist mixes different volumes of ingredients, they add up the total volume to get the final mixture volume. As in Example 13, the sum of 1,550 milliliters of syrup, 725 milliliters of cherry flavor, and 1.25 liters of water (which equals 1,250 milliliters) results in a total volume of 3,525 milliliters or 3.525 liters.
Medical professionals, such as pharmacists and healthcare providers, must be meticulous in dosage calculations to ensure patient safety. Misjudging the necessary dosage of a medication can lead to ineffective treatment or potential harm to the patient. Therefore, understanding the proper way to calculate dosages based on different measurements and concentrations is an essential skill in the medical field.
