Question 1

What is the pharmacological management of diabetic ketoacidosis (DKA) that DHA pharmacists should understand?

Accepted Answer

IV insulin infusion, aggressive fluid resuscitation with normal saline, potassium replacement, and bicarbonate in severe acidosis

Answer

DKA management requires IV regular insulin infusion, aggressive fluid replacement with 0.9% NaCl, potassium supplementation (monitored closely), and sodium bicarbonate only for pH <6.9.

Question 2

What anticoagulant therapy options are available in Dubai and what are their key differences?

Accepted Answer

Warfarin (requires INR monitoring), DOACs like rivaroxaban/apixaban (fixed dosing, fewer interactions), and heparin (IV/SC for acute management)

Answer

Dubai pharmacies dispense warfarin (VKA requiring INR monitoring), DOACs (rivaroxaban, apixaban, dabigatran with fixed dosing and fewer food interactions), and heparins (UFH, LMWH) for acute anticoagulation.

Question 3

What is the DHA pharmacist's role in antibiotic stewardship?

Accepted Answer

Review antibiotic prescriptions for appropriateness, dose optimization, de-escalation, duration, and educate patients on adherence and resistance

Answer

DHA pharmacists are integral to antibiotic stewardship: reviewing prescriptions for indication and appropriateness, recommending dose optimization, suggesting de-escalation, monitoring duration, and patient education on adherence.

Question 4

What is the pharmacokinetic consideration for medication dosing in patients with renal impairment?

Accepted Answer

Medications primarily cleared by the kidneys require dose reduction or interval extension based on estimated GFR/creatinine clearance

Answer

Renally cleared medications require dose adjustment based on eGFR or CrCl calculations, typically through dose reduction or interval extension, to prevent drug accumulation and toxicity.

Question 5

What are the key considerations for medication use during Ramadan that DHA pharmacists must address?

Accepted Answer

Adjust dosing schedules to Suhoor/Iftar times, modify insulin regimens, counsel on hydration, and identify medications requiring non-fasting routes

Answer

DHA pharmacists must help patients adjust medication timing to pre-dawn (Suhoor) and sunset (Iftar) meals, modify diabetes regimens to prevent hypoglycemia, ensure adequate hydration, and identify drugs that break the fast.
