NAC OSCE Patient Management & Treatment — Questions and Answers
Question 1: According to Diabetes Canada 2023 guidelines, which medication should be added first-line alongside metformin in a patient with type 2 diabetes and established cardiovascular disease?
- An SGLT2 inhibitor (e.g., empagliflozin) or GLP-1 receptor agonist with proven CV benefit (Correct answer)
- Sulfonylurea (e.g., glyburide)
- DPP-4 inhibitor (e.g., sitagliptin)
- Insulin glargine
Correct answer: An SGLT2 inhibitor (e.g., empagliflozin) or GLP-1 receptor agonist with proven CV benefit
Diabetes Canada 2023 guidelines recommend SGLT2 inhibitors or GLP-1 receptor agonists as preferred second agents in T2DM with established ASCVD due to demonstrated cardiovascular and renal benefits.
Question 2: A 6-year-old child weighing 20 kg presents to a Canadian emergency department with moderate croup (Westley score 3-5). What is the standard treatment?
- Oral dexamethasone 0.6 mg/kg (single dose) with nebulised epinephrine for moderate cases (Correct answer)
- Inhaled budesonide only
- IV methylprednisolone and admission
- Oral prednisolone 1 mg/kg for 5 days
Correct answer: Oral dexamethasone 0.6 mg/kg (single dose) with nebulised epinephrine for moderate cases
Canadian paediatric guidelines recommend oral or IM dexamethasone 0.6 mg/kg (single dose) for croup; nebulised racemic or L-epinephrine is added for moderate-to-severe cases with stridor at rest.
Question 3: According to the Canadian Hypertension Education Program (CHEP/Hypertension Canada), what is the target blood pressure for a non-diabetic adult with hypertension and no other comorbidities?
- <130/80 mmHg for most patients, and <120 mmHg systolic in high-risk patients (Correct answer)
- <140/90 mmHg for all patients without exception
- <150/90 mmHg for patients over 60
- <135/85 mmHg by home monitoring only
Correct answer: <130/80 mmHg for most patients, and <120 mmHg systolic in high-risk patients
Hypertension Canada 2020+ guidelines recommend a target of <130/80 mmHg for most adults and <120 mmHg systolic for high-risk patients (e.g., established CVD, CKD, diabetes with target organ damage).
Question 4: A 35-year-old pregnant woman at 36 weeks has a group B Streptococcus (GBS)-positive vaginal/rectal swab. According to SOGC guidelines, what is the appropriate management during labour?
- Intrapartum IV penicillin G starting at onset of active labour or rupture of membranes (Correct answer)
- Oral amoxicillin during the third trimester
- No treatment required as GBS is a normal commensal
- Caesarean section to prevent neonatal infection
Correct answer: Intrapartum IV penicillin G starting at onset of active labour or rupture of membranes
SOGC guidelines recommend intrapartum IV penicillin G (or ampicillin) as prophylaxis for GBS-positive mothers to prevent early-onset neonatal GBS disease; antenatal oral antibiotics do not reliably eliminate carriage.
Question 5: A 70-year-old patient with non-valvular atrial fibrillation has a CHA₂DS₂-VASc score of 3. According to CCS guidelines, what anticoagulation is recommended?
- A direct oral anticoagulant (DOAC), preferably over warfarin (Correct answer)
- Aspirin 81 mg daily
- No anticoagulation — the risk is too high in elderly patients
- Warfarin with target INR 2.0-3.0 as first choice
Correct answer: A direct oral anticoagulant (DOAC), preferably over warfarin
CCS Atrial Fibrillation guidelines recommend DOACs over warfarin for stroke prevention in non-valvular AF when CHA₂DS₂-VASc ≥2 in males or ≥3 in females due to superior efficacy and safety profiles.
Question 6: According to Canadian pain management principles and the National Opioid Use Disorder Guideline, what is the MOST appropriate first-line approach for chronic non-cancer low back pain?
- Non-pharmacological therapies (exercise, CBT, physiotherapy) with NSAIDs as first pharmacological option; opioids are NOT first-line (Correct answer)
- Long-acting opioids as first-line due to superior analgesia
- Immediate referral to surgery
- Gabapentin as first-line monotherapy
Correct answer: Non-pharmacological therapies (exercise, CBT, physiotherapy) with NSAIDs as first pharmacological option; opioids are NOT first-line
Canadian guidelines and the National Pain Centre recommend non-pharmacological therapies first; NSAIDs are first-line pharmacotherapy for low back pain, and opioids should only be considered after other treatments have failed, given Canada's opioid crisis.
According to Diabetes Canada 2023 guidelines, which medication should be added first-line alongside metformin in a patient with type 2 diabetes and established cardiovascular disease?
