PATHOPHYSIOLOGY, PHARMACOLOGY & PHYSICAL
ASSESSMENT STUDY GUIDE AND 200 MASTER REVIEW
QUESTIONS WITH DETAILED RATIONALES
1. A patient presents with a new onset of atrial fibrillation. Which of
the following pathophysiological mechanisms is the primary
contributor to the development of this arrhythmia?
A. Increased vagal tone
B. Enhanced automaticity of the SA node
C. Re-entry circuit within the atria
D. Complete heart block
C. Re-entry circuit within the atria
Rationale: Atrial fibrillation is primarily driven by multiple re-entry
wavelets within the atrial tissue, often originating from the pulmonary
veins. This leads to disorganized electrical activity and loss of atrial kick.
2. A 65-year-old male is prescribed warfarin for chronic atrial
fibrillation. Which of the following laboratory values should be
monitored to assess the therapeutic efficacy and safety of this
medication?
A. aPTT
B. INR
C. Bleeding time
D. Platelet count
,B. INR
Rationale: The INR (International Normalized Ratio) is the standard
monitoring parameter for warfarin therapy, typically targeting a range
of 2.0 to 3.0 for atrial fibrillation. The aPTT is used to monitor
unfractionated heparin.
3. During a physical assessment, the nurse practitioner notes a high-
pitched, blowing murmur at the apex that radiates to the axilla. This
finding is most consistent with which valvular disorder?
A. Aortic stenosis
B. Mitral regurgitation
C. Aortic regurgitation
D. Mitral stenosis
B. Mitral regurgitation
Rationale: Mitral regurgitation produces a high-pitched, blowing
holosystolic murmur best heard at the apex and radiating to the axilla.
Aortic stenosis radiates to the carotids, and mitral stenosis is a low-
pitched diastolic rumble.
4. Which of the following physical exam findings is considered a classic
sign of right-sided heart failure?
A. Pulmonary crackles
B. Jugular venous distention
C. Orthopnea
D. Paroxysmal nocturnal dyspnea
B. Jugular venous distention
Rationale: Right-sided heart failure leads to systemic venous congestion,
manifesting as jugular venous distention, peripheral edema, and
hepatomegaly. Pulmonary crackles and orthopnea are signs of left-sided
heart failure.
,5. A patient with a history of myocardial infarction is prescribed a
beta-blocker. What is the primary therapeutic goal of this medication
in post-MI care?
A. Increase heart rate
B. Reduce myocardial oxygen demand
C. Increase cardiac contractility
D. Promote vasodilation
B. Reduce myocardial oxygen demand
Rationale: Beta-blockers decrease heart rate, contractility, and
conduction velocity, thereby reducing myocardial oxygen demand and
preventing further ischemic injury or arrhythmias post-MI.
6. A 55-year-old female presents with fatigue, cold intolerance, and
weight gain. Her TSH is elevated, and her free T4 is low. Which of the
following is the most likely diagnosis?
A. Hyperthyroidism
B. Hypothyroidism
C. Cushing's syndrome
D. Addison's disease
B. Hypothyroidism
Rationale: Elevated TSH with low free T4 is the hallmark of primary
hypothyroidism. Symptoms include fatigue, cold intolerance, weight
gain, and bradycardia.
7. Which of the following medications is the first-line treatment for a
patient newly diagnosed with type 2 diabetes mellitus and no
contraindications?
A. Insulin glargine
B. Metformin
C. Glipizide
, D. Sitagliptin
B. Metformin
Rationale: Metformin is the preferred first-line pharmacologic agent for
type 2 diabetes due to its efficacy, safety profile, weight-neutral effects,
and low cost.
8. A patient presents with sudden onset of severe, sharp chest pain
that worsens with deep inspiration. Auscultation reveals a pleural
friction rub. What is the most likely diagnosis?
A. Myocardial infarction
B. Pericarditis
C. Pneumothorax
D. Pulmonary embolism
B. Pericarditis
Rationale: Pericarditis typically presents with sharp, pleuritic chest pain
that improves when sitting up and leaning forward. A pleural friction
rub is a classic physical exam finding.
9. Which cranial nerve is primarily responsible for assessing the motor
function of the tongue?
A. Cranial Nerve IX (Glossopharyngeal)
B. Cranial Nerve X (Vagus)
C. Cranial Nerve XI (Spinal Accessory)
D. Cranial Nerve XII (Hypoglossal)
D. Cranial Nerve XII (Hypoglossal)
Rationale: Cranial Nerve XII (Hypoglossal) controls tongue movement.
Assessment involves asking the patient to protrude the tongue and
observing for deviation, which indicates a lesion on the same side as the
deviation.
