To find the appropriate dose of phenobarbital in grams for this order, we need to convert the given dose from milligrams (mg) to grams (g).
Given:
Phenobarbital on hand: 15mg/tan Rx
Desired dose: gr 1/2 po (gr means grains, and po means by mouth)
1 grain (gr) is equal to 64.79891 milligrams (mg).
Converting gr 1/2 to milligrams:
1/2 gr = (1/2) * 64.79891 mg
= 32.39945 mg
To convert mg to grams, divide the dose by 1000:
32.39945 mg ÷ 1000 = 0.03239945 g
Therefore, the order is for 0.03239945 grams of phenobarbital.
To determine the appropriate dose of phenobarbital in grams (gr), we need to convert the given dose in milligrams (mg) to grams.
Given:
Phenobarbital available: 15 mg/tab Rx (prescription)
Step 1: Convert mg to grams:
Since 1 gram (g) is equivalent to 1000 milligrams (mg), we can calculate the conversion factor:
15 mg ÷ 1000 = 0.015 g
Step 2: Determine the prescribed dose:
The order is for "phenobarbital gr 1/2 po." This means half a gram (1/2 gr) of phenobarbital needs to be administered orally.
Therefore, the prescribed dose is 0.5 grams.
Please note that "gr" is an abbreviation for "grain," which is an outdated unit of measurement in pharmaceuticals. It is less commonly used now, with most medications measured in milligrams (mg).
