ACCURATE!! 2026 TEST
1.
A 65-year-old man presents with crushing substernal chest
pain lasting 45 minutes. ECG demonstrates ST-segment
elevations in leads II, III, and aVF. Which coronary artery is
most likely occluded?
A. Left anterior descending artery
B. Left circumflex artery
C. Right coronary artery
D. Posterior descending artery
Rationale: Inferior myocardial infarctions involving leads II, III,
and aVF most commonly result from occlusion of the right
coronary artery.
2.
,A patient develops fever, confusion, and nuchal rigidity after
untreated otitis media. CSF shows neutrophilic pleocytosis,
elevated protein, and low glucose. Which organism is most
likely?
A. Neisseria meningitidis
B. Streptococcus pneumoniae
C. Listeria monocytogenes
D. Haemophilus influenzae
Rationale: Streptococcus pneumoniae is the leading cause of
adult bacterial meningitis.
3.
A diabetic patient presents with Kussmaul respirations.
Which acid-base disorder is expected?
A. Respiratory alkalosis
B. Metabolic alkalosis
C. High anion gap metabolic acidosis
D. Normal anion gap metabolic acidosis
Rationale: Diabetic ketoacidosis produces accumulation of
ketoacids resulting in high anion gap metabolic acidosis.
4.
Which cranial nerve mediates the corneal blink reflex
afferent limb?
,A. CN III
B. CN IV
C. CN V1
D. CN VII
Rationale: The ophthalmic division of the trigeminal nerve
detects corneal sensation.
5.
A child develops facial swelling and cola-colored urine
following streptococcal pharyngitis. Diagnosis?
A. IgA nephropathy
B. Poststreptococcal glomerulonephritis
C. Minimal change disease
D. Membranous nephropathy
Rationale: PSGN occurs 1–3 weeks after streptococcal
infection with nephritic syndrome.
6.
Which vitamin deficiency causes megaloblastic anemia with
neurologic symptoms?
A. Folate
B. Vitamin B12
C. Iron
, D. Vitamin C
Rationale: Vitamin B12 deficiency uniquely causes posterior
column degeneration.
7.
A patient with COPD has chronic CO₂ retention. Which renal
adaptation occurs?
A. Decreased bicarbonate
B. Increased bicarbonate reabsorption
C. Increased chloride excretion
D. Increased sodium excretion
Rationale: Kidneys compensate for chronic respiratory
acidosis by retaining bicarbonate.
8.
Which immunoglobulin crosses the placenta?
A. IgA
B. IgM
C. IgG
D. IgE
Rationale: IgG provides passive immunity to the fetus.
