Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins Answer Answer True Rationale: The avoirdupois system is another older system that was very popular when pharmacists routinely had to compound medications on their own. This system uses ounces and grains, but they measure differently than those of the apothecary and household systems. The avoirdupois system is seldom used by prescribers, but may be used for bulk medications that come directly from the manufacturer.
