A patient is prescribed warfarin and starts taking ciprofloxacin. What is the most important clinical concern?
Answer: Increased bleeding risk due to elevated INR
Ciprofloxacin inhibits CYP1A2 and CYP3A4, reducing warfarin metabolism and significantly increasing INR and bleeding risk.
Under DHA regulations, which medication category requires a special controlled substance permit for dispensing in Dubai?
Answer: Schedule I and II opioids
DHA requires a special controlled substance permit for dispensing Schedule I and II opioids in compliance with UAE Federal Law No. 14 of 1995.
A pharmacist receives a prescription for methotrexate 2.5 mg tablets for a rheumatoid arthritis patient. The prescription reads 'take daily.' What is the safest action?
Answer: Contact the prescriber to clarify — methotrexate for RA is typically dosed weekly
Methotrexate for non-oncologic conditions is dosed weekly; daily dosing is a well-documented fatal prescribing error requiring pharmacist intervention.
Which storage condition is required for insulin that is currently in use by the patient?
Answer: Room temperature (up to 25–30°C) for up to 28–30 days
Once opened, most insulin vials or pens can be stored at room temperature (up to 25–30°C) for 28–30 days without significant potency loss.
A patient with severe renal impairment (CrCl < 30 mL/min) is prescribed a standard dose of enoxaparin. What is the pharmacist's primary concern?
Answer: Accumulation leading to increased bleeding risk
Enoxaparin is renally eliminated; reduced kidney function leads to drug accumulation and a markedly elevated bleeding risk requiring dose adjustment.
What is the correct procedure when a dispensing error is discovered after the patient has left the pharmacy?
Answer: Contact the patient immediately, retrieve the incorrect medication, provide the correct one, and report per DHA incident policy
DHA patient safety standards require immediate patient notification, medication retrieval, correct dispensing, and formal incident reporting for all dispensing errors.
Which parameter is most critical to monitor in a patient newly started on lithium therapy?
Answer: Serum lithium levels and renal function
Lithium has a narrow therapeutic index and is renally excreted, so serum lithium levels and renal function must be monitored regularly to prevent toxicity.
