B. perform conversions between decimals, fractions, ratios, and percentages.
C. perform conversions between metric, apothecary, and avoirdupois systems of measure.
D. interpret oral and parenteral medication labels involving capsule and tablet strength dosages, oral solution concentrations, international units, milliequivalents, and weight-to-volume percentage concentrations.
E. perform calculations relating percentage, ratio strength, and concentrations of solutions.
F. perform calculations of dosages of drugs, and dispensing of drug quantities from dosage calculations.
G. record drug administration information in medical records, such as patient records, controlled substances logs, anesthesia logs, and prescription labels.
H. perform calculations involving intravenous preparations, including consideration of isotonicity, milliequivalents, percentage solutions, flow rates, and constant infusions.
