1)
\n" ); document.write( " Use a proportion to find the number of mg, then convert to mcg.
\n" ); document.write( " \"40+mg%2F10+ml+=+x+mg%2F2+ml\"
\n" ); document.write( "\"x+=+8+mg\"\r
\n" ); document.write( "\n" ); document.write( "Convert to micrograms: 1 mg = 1,000 mcg\r
\n" ); document.write( "\n" ); document.write( "\"8+mg+=+8000+mcg\"\r
\n" ); document.write( "\n" ); document.write( "2)1 tablespoonful qid (four times a day) for 3 days (4 X 3) = 12 tablespoonsful. \r
\n" ); document.write( "\n" ); document.write( "1 Tablespoonful = 15 ml approximately. Perhaps your PDR has the exact conversion factor for this but I think it's more like 14.7868 ml per tbsp.\r
\n" ); document.write( "\n" ); document.write( "12 tbsp = 180 ml approximately.
\n" ); document.write( "12 tbsp = 177.4412 ml more precisely.\r
\n" ); document.write( "\n" ); document.write( "3) Flow rate of 30 drops per minute over 6 hours (30 drops/min)(60 min/hr)(6 hrs) = 10,800 drops at 18 gtts/ml (18 drops/ml) = 600 ml.
\n" ); document.write( "
