  1. A patient taking sildenafil for erectile dysfunction is prescribed isosorbide mononitrate for angina. What is the pharmacist's correct action?

    Answer: Contact the prescriber — concurrent use is absolutely contraindicated due to severe hypotension risk

    PDE5 inhibitors combined with nitrates cause a potentially fatal synergistic hypotensive effect and are absolutely contraindicated together.

  2. According to DHA pharmacy standards, what is the minimum record retention period for prescription records in Dubai?

    Answer: 5 years

    DHA regulations require pharmacy prescription records to be retained for a minimum of 5 years for audit and regulatory compliance purposes.

  3. A patient on phenytoin is started on fluconazole. What pharmacokinetic interaction should the pharmacist anticipate?

    Answer: Fluconazole inhibits CYP2C9, increasing phenytoin levels and toxicity risk

    Fluconazole is a potent CYP2C9 inhibitor, which decreases phenytoin metabolism and can cause toxic phenytoin levels.

  4. Which of the following is the correct technique for dispensing cytotoxic medications in a DHA-licensed pharmacy?

    Answer: Preparation in a dedicated biological safety cabinet (BSC) with appropriate PPE

    Cytotoxic drugs must be prepared in a validated biological safety cabinet with full PPE (gloves, gown, mask) to protect staff from hazardous exposure.

  5. A 70-year-old patient taking digoxin develops nausea, visual disturbances, and bradycardia. The serum digoxin level is 3.2 ng/mL. What is the most appropriate immediate action?

    Answer: Hold digoxin, notify the physician immediately, and prepare for potential digoxin-specific antibody (Fab) therapy

    A digoxin level above the therapeutic range (0.5–2 ng/mL) with toxicity symptoms (GI, visual, cardiac) requires immediate drug cessation, physician notification, and potential Fab antidote administration.

  6. Under UAE regulations, which of the following is a requirement before dispensing a prescription-only medication (POM) without a prescription in an emergency?

    Answer: The pharmacist may dispense a limited emergency supply and must obtain a valid prescription within 72 hours

    UAE health regulations allow pharmacists to supply a limited emergency quantity of a POM without a prescription, provided a valid prescription is obtained within 72 hours.

  7. What is the primary reason metronidazole should not be combined with alcohol or alcohol-containing products?

    Answer: Metronidazole inhibits aldehyde dehydrogenase, causing a disulfiram-like reaction

    Metronidazole inhibits aldehyde dehydrogenase, causing acetaldehyde accumulation when alcohol is consumed, leading to flushing, nausea, tachycardia, and hypotension (disulfiram-like reaction).
