Q1. A 58-year-old male with a 40 pack-year smoking history presents with
progressive dyspnea and chronic cough. Pulmonary function tests show FEV₁/FVC
ratio of 0.62 with FEV₁ 55% predicted. According to GOLD 2026 classification,
which statement about his disease activity and treatment is MOST accurate?
A. He has mild COPD (GOLD A) and should start with a short-acting bronchodilator
as needed
B. He has moderate COPD with one moderate exacerbation; dual bronchodilation
(LABA+LAMA) is the preferred initial step with blood eosinophil count to guide ICS
therapy
C. He has severe COPD (GOLD D) and requires immediate triple therapy
D. He has asthma-COPD overlap and should be treated with high-dose ICS
monotherapy
Correct Answer: B. He has moderate COPD with one moderate exacerbation; dual
bronchodilation (LABA+LAMA) is the preferred initial step with blood eosinophil
count to guide ICS therapy [CORRECT]
Rationale: GOLD 2026 revised the ABE classification with a lower threshold for Group
E, now including patients with one moderate exacerbation . FEV₁ 55% predicted
indicates moderate COPD (GOLD 2). The preferred initial pharmacological step is
,dual bronchodilation (LABA+LAMA), with blood eosinophil counts integrated to
guide ICS therapy . Option A understages the disease and uses outdated SABA-only
therapy. Option C overstates severity—triple therapy is reserved for patients with
persistent symptoms/exacerbations despite optimized dual therapy. Option D is
incorrect without evidence of asthma features. NP-Level Principle: GOLD 2026
emphasizes disease activity as a therapeutic target and biomarker-guided precision
medicine. Evidence-Based Citation: GOLD 2026 Report; PMC 2026.
Q2. A patient with chronic kidney disease (eGFR 35 mL/min/1.73m²) develops
metabolic acidosis. Arterial blood gas shows pH 7.30, PaCO₂ 28 mmHg, HCO₃⁻ 14
mEq/L. Which compensatory mechanism is PRIMARY in this scenario?
A. Hyperventilation to decrease PaCO₂ and raise pH
B. Renal retention of bicarbonate
C. Buffering by hemoglobin
D. Bone buffering with calcium phosphate release
Correct Answer: A. Hyperventilation to decrease PaCO₂ and raise pH [CORRECT]
Rationale: In metabolic acidosis, the primary respiratory compensation is
hyperventilation (Kussmaul respirations) to blow off CO₂, which raises pH per the
Henderson-Hasselbalch equation. The expected PaCO₂ in metabolic acidosis can be
estimated by Winter's formula: PaCO₂ = (1.5 × HCO₃⁻) + 8 ± 2 = (1.5 × 14) + 8 = 29
mmHg; the patient's PaCO₂ of 28 is appropriately compensated. Option B is impaired
in CKD (the cause of the acidosis). Options C and D are buffering mechanisms but
not the primary acute compensation. NP-Level Principle: Understanding acid-base
compensation is essential for NP-level diagnostic reasoning and identifying mixed
disorders. Evidence-Based Citation: Harrison's Principles of Internal Medicine, 21st
Ed.
Q3. Which cellular adaptation is characterized by a decrease in cell size and
function due to decreased workload, and is REVERSIBLE if the stimulus is
removed?
,A. Hyperplasia
B. Hypertrophy
C. Atrophy
D. Metaplasia
Correct Answer: C. Atrophy [CORRECT]
Rationale: Atrophy is the decrease in cell size and function due to decreased
workload, hormonal stimulation, or nutrition; it is reversible if the stimulus is
removed. Hyperplasia (Option A) is increased cell number. Hypertrophy (Option B) is
increased cell size due to increased workload. Metaplasia (Option D) is the
replacement of one differentiated cell type with another, often in response to chronic
irritation. NP-Level Principle: Distinguishing cellular adaptations is fundamental to
understanding disease progression and reversibility. Evidence-Based Citation:

Q4. A 45-year-old female presents with fatigue, weight gain, cold intolerance, and
constipation. Laboratory studies show TSH 12.5 mIU/L (elevated), free T₄ 0.6
ng/dL (low), and positive anti-thyroid peroxidase (TPO) antibodies. Which
pathophysiological mechanism is PRIMARILY responsible for her condition?
A. TSH receptor-stimulating antibodies causing thyroid hyperfunction
B. Autoimmune destruction of thyroid follicular cells causing hypothyroidism
C. Iodine deficiency causing decreased thyroid hormone synthesis
D. Pituitary adenoma causing excessive TSH secretion
Correct Answer: B. Autoimmune destruction of thyroid follicular cells causing
hypothyroidism [CORRECT]
Rationale: The clinical picture (hypothyroidism with elevated TSH, low free T₄,
positive TPO antibodies) is classic Hashimoto thyroiditis—autoimmune destruction of
thyroid follicular cells. Option A describes Graves disease (hyperthyroidism). Option C
(iodine deficiency) would not cause positive TPO antibodies. Option D (pituitary
adenoma) would cause elevated TSH with elevated or normal T₄, not low T₄. NP-
Level Principle: Understanding the immunologic basis of endocrine disorders
, guides both diagnosis and long-term monitoring for associated autoimmune
conditions. Evidence-Based Citation: Williams Textbook of Endocrinology, 14th Ed.
Q5. In the inflammatory response, which cell type is the FIRST to arrive at the site
of acute bacterial infection and is primarily responsible for phagocytosis of
bacteria?
A. Macrophages
B. Neutrophils
C. Eosinophils
D. Lymphocytes
Correct Answer: B. Neutrophils [CORRECT]
Rationale: Neutrophils are the first responders in acute inflammation, arriving within
minutes to hours via chemotaxis. They are the primary phagocytes for bacteria in
acute infection. Macrophages (Option A) arrive later (24-48 hours) and are important
for chronic inflammation and antigen presentation. Eosinophils (Option C) are
associated with parasitic infections and allergic responses. Lymphocytes (Option D)
are involved in adaptive immunity, arriving days after initial injury. NP-Level
Principle: Understanding the cellular timeline of inflammation guides clinical
interpretation of CBC with differential and selection of anti-inflammatory therapies.

Immunology, 10th Ed.
Q6. A patient with heart failure develops peripheral edema and pulmonary
congestion. Which hemodynamic principle BEST explains the fluid shift into the
interstitial space?
A. Decreased hydrostatic pressure in the capillaries
B. Increased hydrostatic pressure in the capillaries due to increased preload
C. Decreased oncotic pressure in the interstitial space
D. Increased lymphatic drainage
