,1. A 45-year-old female presents with fatigue, cold intolerance, and a sluggish reflex
relaxation phase. Laboratory results show an elevated TSH and a low free T4. Which of
the following pathophysiological mechanisms describes the most common cause of this
condition?
A) Autoimmune destruction of TSH receptors
B) Autoimmune-mediated destruction of thyroid peroxidase
C) Autonomous hypersecretion of thyroid hormone
D) Iodine deficiency-induced hyperthermia
Rationale: The clinical presentation and lab values point to primary hypothyroidism,
most commonly caused by Hashimoto's thyroiditis. This is an autoimmune disorder
characterized by antibodies against thyroid peroxidase (TPO) and thyroglobulin, leading
to gradual destruction of the thyroid gland.
2. A clinician is prescribing an ACE inhibitor for a patient with hypertension and chronic
kidney disease. Which laboratory parameter must be closely monitored within 1 to 2
weeks of initiating this medication?
A) Serum sodium and calcium
B) Serum potassium and creatinine
C) Liver function enzymes
D) Total cholesterol and triglycerides
Rationale: ACE inhibitors block aldosterone secretion, which can lead to potassium
retention (hyperkalemia). They also dilate the efferent arteriole in the kidney, which can
cause a transient, acceptable decrease in GFR, presenting as a modest rise in serum
creatinine.
3. During a cardiac assessment, the clinician notes a low-pitched, mid-diastolic murmur
heard best at the apex with the patient in the left lateral decubitus position. This finding
is most indicative of which valvular disorder?
A) Mitral regurgitation
B) Aortic stenosis
C) Mitral stenosis
D) Aortic regurgitation
Rationale: A low-pitched, rumbling mid-diastolic murmur heard best at the apex with the
bell of the stethoscope in the left lateral decubitus position is the classic sign of mitral
stenosis.
4. A 62-year-old male with a history of chronic obstructive pulmonary disease (COPD)
presents with worsening shortness of breath. Arterial blood gas (ABG) analysis reveals a
, pH of 7.31, PaCO2 of 55 mmHg, and HCO3- of 28 mEq/L. How should this acid-base
imbalance be classified?
A) Partially compensated metabolic acidosis
B) Uncompensated respiratory alkalosis
C) Partially compensated respiratory acidosis
D) Fully compensated metabolic alkalosis
Rationale: The pH is acidic (<7.35), the PaCO2 is elevated (>45 mmHg, pointing to a
respiratory cause), and the HCO3- is elevated (>26 mEq/L), indicating the kidneys have
begun to retain bicarbonate to compensate for the respiratory acidosis, though the pH is
not yet normalized.
5. A patient is diagnosed with deep vein thrombosis (DVT) and started on unfractionated
heparin. What is the primary mechanism of action of heparin?
A) Directly inhibits free and bound thrombin
B) Blocks the synthesis of vitamin K-dependent clotting factors
C) Potentiates the action of antithrombin III to inactivate factor Xa and thrombin
D) Inhibits platelet aggregation by blocking ADP receptors
Rationale: Unfractionated heparin works indirectly by binding to antithrombin III,
causing a conformational change that accelerates its inhibition of activated clotting
factors, primarily thrombin (Factor IIa) and Factor Xa.
6. During a cranial nerve evaluation, the clinician asks the patient to puff out their cheeks,
smile, and wrinkle their forehead. The patient is unable to move the right side of their
face. Which cranial nerve is affected?
A) Cranial Nerve V (Trigeminal)
B) Cranial Nerve VII (Facial)
C) Cranial Nerve IX (Glossopharyngeal)
D) Cranial Nerve XI (Accessory)
Rationale: Cranial Nerve VII (the facial nerve) controls the muscles of facial expression.
Asymmetry or paralysis during these maneuvers indicates a CN VII lesion or palsy.
7. A 28-year-old female presents with severe, unilateral, throbbing headache accompanied
by nausea and photophobia. She notes seeing flashing lights prior to the onset of the
pain. Which medication is most appropriate for acute first-line abortive therapy?
A) Propranolol
B) Topiramate
C) Sumatriptan
D) Amitriptyline
Rationale: Triptans, such as sumatriptan, are selective 5-HT1B/1D receptor agonists used
, as first-line abortive therapy for moderate-to-severe migraine headaches. Propranolol,
topiramate, and amitriptyline are used for prophylaxis, not acute abortive management.
8. Which of the following physical assessment maneuvers is performed by flexing the
patient's hip and knee to 90 degrees and then attempting to straighten the leg, looking
for resistance or pain in the hamstring?
A) Brudzinski's sign
B) Kernig's sign
C) McBurney's sign
D) Murphy's sign
Rationale: Kernig's sign is a physical exam finding indicative of meningeal irritation.
Resistance or pain upon leg extension when the hip is flexed constitutes a positive sign.
9. A 55-year-old patient with type 2 diabetes mellitus requires the addition of a medication
that lowers postprandial glucose levels by delaying carbohydrate absorption in the small
intestine. Which class of medication fits this description?
A) Sulfonylureas
B) Thiazolidinediones
C) Alpha-glucosidase inhibitors
D) SGLT2 inhibitors
Rationale: Alpha-glucosidase inhibitors (like acarbose) competitively inhibit membrane-
bound intestinal alpha-glucosidase enzymes, delaying the digestion and absorption of
complex carbohydrates and slowing down glucose absorption to lower postprandial
spikes.
10. A patient presents with acute right upper quadrant abdominal pain that radiates to the
right scapula, accompanied by nausea and fever. On exam, there is sharp inspiratory
arrest when the clinician palpates under the right costal margin. What is the most li kely
diagnosis?
A) Acute pancreatitis
B) Acute cholecystitis
C) Acute appendicitis
D) Peptic ulcer disease
Rationale: The presentation and positive Murphy's sign (inspiratory arrest during deep
palpation of the right upper quadrant) are highly specific for acute inflammation of the
gallbladder (cholecystitis).
11. What is the fundamental cellular pathophysiology underlying cystic fibrosis?
A) Deficiency of alpha-1 antitrypsin activity
B) A defect in a chloride channel protein leading to thick, viscous secretions
