minims problem

I can't believe they are still teaching this.....

I haven't seen the apothecary system used in years with the exception of ASA, Tylenol, and some B&O/opiate suppositories. Like all conversion problems you have to know your conversion values.

Here is a thread about this....https://allnurses.com/nursing-student-assistance/how-convert-drams-741698-page2.html

how to convert drams to teaspoons for nurses....

1 dram (fl dr) = 60 minims

1 teaspoon (tsp) = 60 drops (gtt)

1 minim = 1 drop (gt)

there are certain essential parts to every equation.......

desired dose: ?tsp

concentration: 1dr/60minims

volume on hand: 6dr

lb to kg: n/a

looking for: tsp

administration set up: n/a

any conversions necessary? yes

if you have 6dr and 1 dr equals 60 minims and 1 minim equals 1 gtt(drop) and there are 60ggts to 1tsp.......what is the answer?

1. determine what you want to know. read the problem and identify what you're being asked to figure out.

example: "how many teaspoons are in 6 drams"

a. rephrase if necessary using "per." example: you want to know "milligrams per liter."

b. translate into "math terms" using appropriate abbreviations to end up with "arms/tsp" as your answer

2. determine what you already know.

a. what are you given by the problem. "you know that you have 6 (six) drams (dr)

• rephrase if necessary. "i have six drams how many teaspoons do i need to equal 6drams

• translate into math terms using abbreviations

example: 6dr = ? tsp

— if a given is in the form mg/kg/day, rewrite as mg/kg x day.

— if a percentage is given, e.g. 25%, rewrite as 25/100 with appropriate labels.

b. determine conversion factors that may be needed and write them in a form you can use.

example: 1 dram (fl dr) = 60 minims

1 teaspoon (tsp) = 60 drops (gtt)

1 drop (gt) = 1 minim

• factors known from memory:

• factors from a conversion table:

(d/a)x q=x

where,

d= dose ordered

a=available strength

q=quantity of medication that has that strength

desired dose x on hand

quantity/concentration = to be given

if you have 6dr and 1 dr equals 60 minims and 1 minim equals 1gtt(drop) and there are 60ggts to 1tsp.......what is the answer?
