A medication is available in 30mg. tablets. A patient is given a prescription for gr. ii. How many tablets should the patient take?
I am not sure how to work this problem out, and i am confused on the gr. ii. part, i do not know what it means, please help. thank you
To determine how many tablets the patient should take, we need to understand what "gr. ii" means. In medical terminology, "gr." represents the abbreviation for "grain," which is a unit of measurement used in pharmacy. However, it's important to note that the use of grains as a unit of measurement is not very common nowadays, so it's understandable that it may cause confusion.
In this case, "gr. ii" is equivalent to "2 grains." To convert grains to milligrams, we need to know that 1 grain is equal to approximately 65 milligrams. So, "2 grains" would be equivalent to 2 multiplied by 65 milligrams, which equals 130 milligrams.
Since the medication is available in 30mg tablets, we can calculate the number of tablets the patient should take by dividing the prescribed dosage (130mg) by the dosage per tablet (30mg):
Number of tablets = Total dosage prescribed (in mg) / Dosage per tablet (in mg)
Number of tablets = 130mg / 30mg
Number of tablets ≈ 4.33
Since the number of tablets needs to be a whole number, the patient should take either 4 or 5 tablets, depending on the specific instructions given by the healthcare provider.
The abbreviation "gr." is commonly used to represent the unit of measurement called a "grain." In this case, "gr. ii" stands for 2 grains. To determine the number of tablets the patient should take, we need to convert 2 grains to milligrams (mg) since the medication is available in 30mg tablets.
1 grain is approximately equal to 64.79891 milligrams (mg). Therefore, 2 grains can be converted to milligrams by multiplying 2 by 64.79891, which equals 129.59782 mg.
Since each tablet is 30mg, we divide the total dosage (129.59782 mg) by the dosage per tablet (30 mg) to find the number of tablets the patient should take:
129.59782 mg ÷ 30 mg = 4.32 tablets.
Since we cannot have a fraction of a tablet, we round up to the nearest whole number. Therefore, the patient should take 5 tablets (4 tablets would be insufficient dosage).
However, it is important to note that dosages and medication instructions should be followed as prescribed by a healthcare professional. So, please consult a healthcare professional or pharmacist for accurate and personalized advice.
