Clinical Practice & Guidelines Flashcards

A 68-year-old diabetic patient on metformin presents with eGFR of 42 mL/min/1.73m². According to DHA-aligned international guidelines, which is the MOST appropriate management decision regarding metformin?

Answer: Reduce metformin dose by 50% and monitor eGFR every 3 months

At eGFR 30–45 mL/min/1.73m², current guidelines (ADA/KDIGO, adopted by DHA) recommend reducing the metformin dose by approximately 50% and increasing monitoring frequency to every 3 months. Metformin is contraindicated only when eGFR falls below 30. Immediate discontinuation at eGFR 42 is overly aggressive, and continuing full-dose without adjustment risks lactic acidosis accumulation.

Under the DHA Patient Rights Charter, a competent adult patient refuses a blood transfusion on religious grounds despite a hemoglobin of 5.2 g/dL and active bleeding. The most appropriate clinician action is:

Answer: Document the refusal, explore all blood-sparing alternatives, and respect the decision

DHA guidelines align with international bioethical standards: a competent adult has the unequivocal right to refuse treatment, including blood products, even when life-threatening. The clinician must document the informed refusal, ensure the patient understands the consequences, and exhaust all blood-sparing strategies (e.g., erythropoietin, cell salvage, iron). Overriding a competent patient's refusal constitutes assault, and court orders are not required when the patient is conscious and competent.

A physician in a DHA-licensed facility suspects a colleague of practicing while impaired by opioids but has no direct evidence. According to DHA Professional Conduct regulations, what is the FIRST required action?

Answer: Report the suspicion confidentially to the facility's Chief Medical Officer or Patient Safety Officer

DHA regulations place a mandatory duty on all licensed practitioners to report credible concerns about impaired colleagues — patient safety supersedes collegial loyalty. The correct first step is internal escalation to the facility's CMO or designated Patient Safety Officer, who then activates the formal investigation and DHA reporting pathway. Waiting for conclusive evidence or confronting the colleague alone delays protective action. Bypassing internal governance and going directly to DHA first is appropriate only if the internal report is ignored or suppressed.

According to UAE Federal Law No. 4 of 2016 on Medical Liability, the statute of limitations for filing a medical negligence claim is:

Answer: 1 year from the date the harm was discovered or should reasonably have been discovered

UAE Federal Law No. 4 of 2016 (Medical Liability Law) sets a 1-year limitation period commencing from the date the patient discovered — or should reasonably have discovered — the harm. This 'discovery rule' distinguishes it from a fixed-date rule. Practitioners must maintain complete, legible medical records beyond this period, as the limitation clock starts at discovery, not at the time of the act.

A 34-year-old woman at 28 weeks gestation presents with a BP of 158/106 mmHg on two readings 4 hours apart, 2+ proteinuria, and platelets of 89,000/µL. She has no headache or visual changes. Which diagnosis and management pathway is MOST accurate per current obstetric guidelines?

Answer: Severe preeclampsia with severe features; initiate IV magnesium sulfate, antihypertensive therapy, and plan delivery within 24–48 hours

A platelet count below 100,000/µL constitutes a 'severe feature' of preeclampsia per ACOG/FIGO guidelines (adopted in DHA protocols). Combined with BP ≥160/110 mmHg, this patient has severe preeclampsia with severe features. Management mandates IV magnesium sulfate for seizure prophylaxis, acute antihypertensive treatment (IV labetalol or hydralazine), and delivery planning within 24–48 hours given gestational age of 28 weeks (after corticosteroids). Full HELLP requires additional criteria (hemolysis, AST/ALT elevation); a cesarean is not always mandatory and route depends on obstetric factors.

A DHA-licensed general practitioner initiates antibiotic therapy for uncomplicated community-acquired pneumonia in an otherwise healthy 45-year-old non-smoker with no recent hospitalizations. Per UAE Antimicrobial Stewardship guidelines, the preferred first-line regimen is:

Answer: Amoxicillin 1 g three times daily for 5 days

For low-risk CAP in a healthy adult with no comorbidities or risk factors for atypical organisms, UAE Antimicrobial Stewardship guidelines — aligned with NICE and IDSA/ATS — recommend amoxicillin (high-dose) as the narrowest-spectrum effective choice. Amoxicillin-clavulanate is unnecessarily broad for uncomplicated CAP. Azithromycin monotherapy has rising resistance rates and is not recommended as sole therapy. Fluoroquinolones (levofloxacin) are reserved for patients with comorbidities, penicillin allergy, or antibiotic failure — using them empirically in low-risk cases contributes to resistance.
