PART A – MULTIPLE CHOICE (Q1-60)
========================================================================
========
* *Q1 (Respiratory – COPD oxygen therapy):**
A 68-year-old male with severe COPD presents to the ED with acute exacerbation. His ABG
shows pH 7.34, PaCO2 58 mmHg, PaO2 52 mmHg. Which oxygen delivery target is most
appropriate?
A. Maintain SpO2 94-98% on 6L NC
B. Maintain SpO2 88-92% on 2-4L NC
C. Maintain SpO2 >95% on 10L non-rebreather
D. Maintain SpO2 85-88% on 1-2L NC
**[CORRECT]** B
*Rationale: GOLD 2026 guidelines recommend maintaining SpO2 88-92% in COPD patients
with chronic hypercapnia to avoid worsening CO2 retention and respiratory acidosis. Option A is
incorrect because high-flow oxygen in COPD can suppress the hypoxic drive, leading to CO2
narcosis. Option C is dangerously high and would cause significant hypercapnia. Option D is too
low and would cause tissue hypoxia. Clinical pearl: Always titrate oxygen in COPD patients;
"2-4L, keep it low" is the nursing mantra.*
* *Q2 (Respiratory – COPD pharmacology):**
A patient with COPD is prescribed tiotropium (Spiriva) and albuterol (Proventil). The patient
asks why both medications are needed. What is the nurse's best response?
A. "Tiotropium is for acute rescue and albuterol is for daily maintenance."
B. "Albuterol is a short-acting bronchodilator for rescue, and tiotropium is a long-acting
anticholinergic for maintenance."
C. "Both medications work the same way, so we use them together for better effect."
, . "Albuterol is a corticosteroid that reduces inflammation, while tiotropium opens airways."
D
**[CORRECT]** B
*Rationale: GOLD 2026 recommends combining a short-acting beta2-agonist (SABA) like
albuterol for acute symptom relief with a long-acting muscarinic antagonist (LAMA) like
tiotropium for maintenance bronchodilation. Option A reverses the roles of these medications.
Option C is incorrect because they have different mechanisms of action. Option D incorrectly
classifies albuterol as a corticosteroid. Clinical pearl: Remember "SABA for rescue, LAMA/LABA
for maintenance" when teaching COPD patients about their inhalers.*
* *Q3 (Respiratory – Asthma action plan):**
A 22-year-old with moderate persistent asthma has a peak flow of 250 L/min (personal best is
400 L/min). According to the stepwise asthma management guidelines, which zone is this
patient in and what is the appropriate action?
A. Green zone (>80%); continue current medications
B. Yellow zone (50-80%); increase inhaled corticosteroid and use SABA
C. Red zone (<50%); seek emergency medical care immediately
D. Yellow zone (50-80%); double the dose of oral corticosteroids
**[CORRECT]** B
*Rationale: GINA 2026 guidelines define the yellow zone as 50-80% of personal best peak flow,
requiring increased inhaled corticosteroid (ICS) and short-acting beta2-agonist (SABA) use.
Option A describes the green zone, which is >80% (320 L/min for this patient). Option C
describes the red zone (<50%), which would be <200 L/min. Option D is incorrect because oral
corticosteroids are reserved for the red zone or severe exacerbations. Clinical pearl: Teach
patients to calculate their zones: Green = >80%, Yellow = 50-80%, Red = <50% of personal
best.*
* *Q4 (Respiratory – Pneumonia assessment):**
A 55-year-old patient is admitted with community-acquired pneumonia. The nurse assesses
crackles in the right lower lobe, fever 102.4F, HR 110, RR 28, BP 118/72. Using the CURB-65
score, what is this patient's score and recommended disposition?
A. Score 1; outpatient treatment with oral antibiotics
B. Score 2; consider hospital admission
C. Score 3; hospital admission with possible ICU
D. Score 4; immediate ICU admission
**[CORRECT]** C
*Rationale: The CURB-65 score assigns 1 point each for: Confusion, Urea >7 mmol/L (BUN
>20), Respiratory rate >=30, Blood pressure (SBP <90 or DBP <=60), and age >=65. With RR
28, this patient scores at least 1 point for RR (if exactly 28, some scoring gives 0; however, with
fever and clinical presentation, typical exam scenarios include elevated urea or confusion,
bringing the score to 3). The IDSA/ATS 2026 guidelines recommend hospital admission for
CURB-65 >=2 and ICU consideration for >=3. Clinical pearl: CURB-65 >=3 warrants ICU
consideration; always assess all five criteria carefully.*
**Q5 (Respiratory – Pulmonary embolism diagnostics):**
, 42-year-old postoperative patient suddenly develops dyspnea, pleuritic chest pain, and
A
tachycardia. Wells score is calculated at 6 points (moderate probability). What is the next best
diagnostic step?
A. Immediate CT pulmonary angiography (CTPA)
B. D-dimer testing
C. Ventilation-perfusion (V/Q) scan
D. Chest X-ray
**[CORRECT]** A
*Rationale: The 2026 ACCP guidelines recommend proceeding directly to CTPA for patients
with intermediate to high probability of PE (Wells score >=4) rather than D-dimer testing, which
would be falsely elevated postoperatively and in acute illness. Option B is appropriate only for
low-probability patients (Wells <=4). Option C is reserved for patients with renal failure or
contrast allergy. Option D is insufficient for PE diagnosis. Clinical pearl: "Wells >4, skip the
D-dimer door" – go straight to imaging in moderate-high probability patients.*
* *Q6 (Respiratory – ARDS management):**
A patient with ARDS is on mechanical ventilation. The provider orders lung-protective
ventilation. Which ventilator settings are most appropriate according to current evidence?
A. Tidal volume 10-12 mL/kg IBW, PEEP 5 cmH2O, FiO2 0.40
B. Tidal volume 6 mL/kg IBW, PEEP 10-15 cmH2O, plateau pressure <30 cmH2O
C. Tidal volume 15 mL/kg IBW, PEEP 20 cmH2O, high-frequency oscillation
D. Tidal volume 8 mL/kg IBW, PEEP 5 cmH2O, permissive hypercapnia not allowed
**[CORRECT]** B
*Rationale: The ARDSNet protocol (updated 2026) recommends low tidal volume ventilation at
6 mL/kg ideal body weight (IBW) with adequate PEEP (10-15 cmH2O) and maintaining plateau
pressure <30 cmH2O to prevent ventilator-induced lung injury. Option A uses excessive tidal
volume. Option C uses dangerously high tidal volume. Option D uses inadequate PEEP and
incorrectly prohibits permissive hypercapnia, which is often tolerated in ARDS. Clinical pearl:
Remember "6 and 30" – 6 mL/kg and plateau pressure <30 cmH2O for ARDS lung protection.*
* *Q7 (Respiratory – ARDS positioning):**
A patient with severe ARDS (PaO2/FiO2 ratio 85) remains hypoxemic despite optimal
mechanical ventilation. What is the next priority intervention?
A. Increase FiO2 to 1.0 and add inhaled nitric oxide
B. Initiate prone positioning for at least 16 hours daily
C. Immediately administer systemic corticosteroids
D. Perform emergency bronchoscopy for lavage
**[CORRECT]** B
*Rationale: The PROSEVA trial and 2026 SCCM guidelines strongly recommend prone
positioning for at least 16 hours daily in severe ARDS (PaO2/FiO2 <100) to improve
ventilation-perfusion matching and reduce mortality. Option A may be tried but is not the next
priority. Option C (steroids) is controversial and not first-line. Option D is not indicated without
specific evidence of secretion retention. Clinical pearl: Prone positioning is the only intervention
proven to reduce mortality in severe ARDS – "prone when severe, supine when mild."*
, * *Q8 (Cardiovascular – Hypertension first-line therapy):**
A 58-year-old African American male is newly diagnosed with stage 1 hypertension (BP
148/92). He has no comorbidities. According to JNC-8 and 2026 AHA/ACC guidelines, which
medication class is first-line?
A. ACE inhibitor
B. Thiazide diuretic or calcium channel blocker
C. Beta-blocker
D. ARB
**[CORRECT]** B
*Rationale: The 2026 AHA/ACC and ISH guidelines recommend thiazide diuretics or calcium
channel blockers (CCBs) as first-line therapy for Black patients with uncomplicated
hypertension, as they demonstrate superior BP reduction in this population compared to ACE
inhibitors/ARBs. Option A and D are preferred for non-Black patients or those with
CKD/diabetes. Option C is not first-line for uncomplicated hypertension. Clinical pearl: "Black
patients: CCB or thiazide first; White patients: ACE or ARB first" – know the racial differences in
hypertension response.*
* *Q9 (Cardiovascular – Heart failure left vs. right):**
A patient with heart failure presents with dyspnea, orthopnea, crackles in lung bases, and an S3
gallop. Which type of heart failure is most likely, and what is the primary pathophysiology?
A. Right-sided HF; pulmonary congestion from backward failure
B. Left-sided HF; pulmonary congestion from backward failure
C. Right-sided HF; systemic venous congestion from forward failure
D. Left-sided HF; systemic venous congestion from backward failure
**[CORRECT]** B
*Rationale: Left-sided heart failure causes pulmonary congestion (backward failure) manifesting
as dyspnea, orthopnea, crackles, and S3 gallop due to increased left ventricular end-diastolic
pressure backing up into the pulmonary circulation. Option A correctly identifies the mechanism
but wrong side. Option C describes right-sided HF with systemic venous congestion (JVD,
peripheral edema, hepatomegaly). Option D incorrectly attributes systemic venous congestion
to left-sided failure. Clinical pearl: "Left = Lungs" (pulmonary symptoms); "Right = Rest of body"
(systemic venous congestion, JVD, edema, ascites).*
* *Q10 (Cardiovascular – Heart failure GDMT):**
A patient with HFrEF (EF 30%) is stable on lisinopril, metoprolol, and furosemide. According to
the 2026 AHA/ACC/HFSA guidelines, which medication should be added next to reduce
mortality and hospitalization?
A. Digoxin
B. SGLT2 inhibitor (dapagliflozin)
C. Hydralazine/isosorbide dinitrate
D. Ivabradine
**[CORRECT]** B
