B. workers' compensation. C. a pharmacy benefit manager. D. a health maintenance organization. The key (D) is correct because it is the only choice that requires use of a network provider.

Which of the medications is on the Institute for Safe Medication Practices List of Confused Drug Names because it is available in two different chemical forms that can be easily confused? A. Labetalol B. Hydralazine C. Nifedipine D. Metoprolol The key (D) is correct because Metoprolol comes in Tartrate and Succinate and should be double checked for correct formulation.

Which of the following medications is exempt from the Poison Prevention Packaging Act requirement for child-resistant containers? A. Nitroglycerin sustained release capsules B. Potassium chloride C. Isosorbide D. Cholestyramine powder The key (D) is correct because cholestyramine powder, unlikely to harm a child in the quantities that are dispensed but could if ingested at one time, is exempt from the requirement for child-resistant containers. Although some dosage forms of nitroglycerin (sublingual), potassium chloride (those in unit dose packages), and isosorbide (dinitrate in sublingual or chewable tablets of 10 mg or less) are also exempt, other dosage forms of these are not, so these medications, in their current form, are incorrect.

B. refuse to fill the prescription and return it to the patient. C. call the regional DEA office to report a forged prescription. D. fill the prescription as written. The key (D) is correct because, per the prescription, you can take up to 4 tablets per day which means a maximum of 120 tablets in one month.

What volume, in milliliters, of a drug for injection 250 mg/10 mL should be used to fill an order for 15 mg? A. 0.6 B. 6 C. 10 D. 16.6 The key (A) is correct. 250 mg divided by 10 mL equals 25 mg per 1 mL. 15 mg divided by 25 mg equals the volume needed to provide 15 mg.
