INTRODUCTION
This comprehensive examination is meticulously designed to prepare candidates for the Physician
Assistant National Certifying Examination (PANCE). It assesses a broad spectrum of medical knowledge,
from foundational pathophysiological principles to advanced clinical decision-making in real-world
scenarios. The questions are structured in a multiple-choice format, mirroring the actual exam's style,
and emphasize the application of evidence-based medicine, patient safety, ethical standards, and
professional judgment. This rigorous assessment is intended to serve as a definitive study tool, helping to
identify areas of strength and those requiring further review. Success on this practice examination reflects
a deep understanding of the core competencies required for competent and compassionate patient care,
ensuring readiness for the challenges of clinical practice and the certifying exam itself.
SECTION ONE: QUESTIONS 1–100
Question 1
A 72-year-old male with a history of hypertension and type 2 diabetes presents with sudden onset of
severe, tearing chest pain radiating to his back. His blood pressure is 180/110 mmHg in the right arm
and 140/80 mmHg in the left arm. Which of the following is the most appropriate initial diagnostic
study?
A. Chest X-ray
,B. Electrocardiogram (ECG)
C. Computed Tomography Angiography (CTA)
D. Transthoracic Echocardiogram
🟢 C. Computed Tomography Angiography (CTA)
🔴 Explanation: The patient's presentation with severe, tearing chest pain radiating to the back, along
with a significant blood pressure differential between arms, is highly suggestive of an acute aortic
dissection. CTA of the chest is the gold-standard imaging modality for rapid and accurate diagnosis of
aortic dissection. While a Chest X-ray may show a widened mediastinum, it is not sensitive or specific
enough for definitive diagnosis. An ECG is essential to rule out myocardial infarction but does not
diagnose dissection. A transthoracic echocardiogram can be useful but is less sensitive than CTA for
visualizing the entire thoracic aorta, particularly the ascending and descending segments.
Question 2
A 45-year-old female with a history of asthma presents with increased work of breathing and a peak
expiratory flow rate of 40% of her personal best. She is using accessory muscles and is unable to speak
in full sentences. What is the most appropriate initial step in management?
A. Administer a single dose of oral prednisone
B. Initiate oxygen therapy to maintain SpO2 > 92%
C. Administer continuous nebulized albuterol
D. Perform endotracheal intubation
🟢 C. Administer continuous nebulized albuterol
🔴 Explanation: This patient is experiencing a severe acute asthma exacerbation, as indicated by a
peak flow < 50% of predicted, use of accessory muscles, and inability to speak in full sentences. The
initial management of a severe exacerbation should focus on rapid administration of a short-acting
beta-agonist (SABA), such as continuous nebulized albuterol. While oxygen, systemic corticosteroids,
and intubation are important in the treatment algorithm, the immediate priority is bronchodilation.
Intubation is a last resort for patients with impending respiratory failure, and would be preceded by
these other measures.
Question 3
A 28-year-old pregnant female at 34 weeks gestation complains of a sudden onset of severe, sharp
abdominal pain, vaginal bleeding, and a rigid, board-like abdomen. Fetal heart tones are bradycardic.
What is the most likely diagnosis?
A. Placenta previa
B. Placental abruption
C. Preterm labor
D. Uterine rupture
🟢 B. Placental abruption
🔴 Explanation: The classic triad of sudden-onset severe abdominal pain, vaginal bleeding, and uterine
rigidity (board-like abdomen) in the third trimester of pregnancy is most indicative of placental
abruption. This condition involves the premature separation of the placenta from the uterine wall. Fetal
bradycardia is a concerning sign of fetal distress. Placenta previa typically presents with painless, bright
red bleeding. Preterm labor is characterized by regular contractions and cervical changes without the
acute pain and rigidity. Uterine rupture is a rare but catastrophic event usually associated with a prior
,uterine scar and would present with similar symptoms, but placental abruption is a more common and
likely diagnosis in this scenario.
Question 4
Which of the following is the most common cause of community-acquired pneumonia (CAP) in a
previously healthy, immunocompetent adult?
A. Haemophilus influenzae
B. Mycoplasma pneumoniae
C. Streptococcus pneumoniae
D. Chlamydia pneumoniae
🟢 C. Streptococcus pneumoniae
🔴 Explanation: Streptococcus pneumoniae remains the most frequently identified pathogen in cases of
community-acquired pneumonia in otherwise healthy adults. While Mycoplasma pneumoniae is a
common cause, especially in younger individuals and in outbreaks, S. pneumoniae is the single most
common bacterial cause overall. Haemophilus influenzae is more common in patients with underlying
lung disease, and Chlamydia pneumoniae is a less frequent cause.
Question 5
A 65-year-old male with a history of coronary artery disease and heart failure presents with increasing
dyspnea and orthopnea. On exam, he has jugular venous distention, crackles in the bases of his lungs,
and 2+ pitting edema in his lower extremities. Which of the following findings would most likely be
expected on auscultation of the heart?
A. A loud S1 heart sound
B. A fixed, split S2 heart sound
C. An S3 gallop
D. A systolic ejection murmur at the right upper sternal border
🟢 C. An S3 gallop
🔴 Explanation: The patient is exhibiting signs of acute or worsening heart failure with fluid overload.
The presence of an S3 gallop, which corresponds to rapid ventricular filling in early diastole, is a classic
finding in patients with decompensated heart failure and volume overload. A loud S1 can be seen in
mitral stenosis. A fixed, split S2 is characteristic of an atrial septal defect. A systolic ejection murmur at
the right upper sternal border is typical of aortic stenosis.
Question 6
A 55-year-old male with a history of hepatitis C presents with ascites, jaundice, and confusion. On
exam, he has asterixis and fetor hepaticus. What is the most appropriate initial treatment for his
altered mental status?
A. Intravenous albumin
B. Administration of lactulose
C. High-dose intravenous diuretics
D. Oral antibiotics such as rifaximin
🟢 B. Administration of lactulose
🔴 Explanation: The patient is exhibiting signs of hepatic encephalopathy, a complication of liver
failure. The primary goal of treatment is to reduce the production and absorption of ammonia in the
gut. Lactulose is a non-absorbable disaccharide that acidifies the colon, converting ammonia to
, ammonium, which is then excreted. This is the first-line therapy for overt hepatic encephalopathy.
Rifaximin is a non-absorbable antibiotic that is also used to reduce ammonia-producing bacteria, but it
is typically used as an adjunct to or maintenance therapy after lactulose, or in patients who cannot
tolerate lactulose. Intravenous albumin and diuretics are used to manage ascites and fluid balance but
do not treat the underlying cause of the encephalopathy.
Question 7
A 30-year-old female presents with a several-month history of fatigue, joint pain, a malar rash, and
photosensitivity. Laboratory findings reveal anemia, leukopenia, and a positive antinuclear antibody
(ANA) test. Which of the following autoantibodies is most specific for this condition?
A. Anti-dsDNA
B. Anti-Sm
C. Anti-Ro (SS-A)
D. Anti-La (SS-B)
🟢 B. Anti-Sm
🔴 Explanation: The constellation of symptoms and laboratory findings is classic for Systemic Lupus
Erythematosus (SLE). While anti-dsDNA is a highly specific antibody for SLE, anti-Sm (Smith) is
considered the most specific diagnostic marker for the disease. Anti-dsDNA is also specific but is
associated with disease activity, particularly lupus nephritis. Anti-Ro (SS-A) and anti-La (SS-B) are more
commonly associated with Sjögren's syndrome.
Question 8
A 25-year-old male is brought to the emergency department after a motor vehicle accident. He has a
depressed skull fracture and is suspected of having an epidural hematoma. Which of the following is
the most characteristic clinical finding?
A. A lucid interval followed by a rapid decline in consciousness
B. A rapid onset of coma with no prior symptoms
C. A slow, progressive decline in consciousness over days
D. Fluctuating levels of consciousness with confusion
🟢 A. A lucid interval followed by a rapid decline in consciousness
🔴 Explanation: An epidural hematoma is classically associated with a "lucid interval," where the
patient appears to recover neurologically after the initial head injury, only to rapidly deteriorate as the
arterial (usually middle meningeal) bleed expands and increases intracranial pressure. This is
contrasted with a subdural hematoma, which tends to have a slower, more gradual onset of
symptoms.
Question 9
A 60-year-old male with a history of chronic obstructive pulmonary disease (COPD) and type 2
diabetes is admitted for a COPD exacerbation. He is started on a course of high-dose corticosteroids.
Which of the following is a significant adverse effect of this medication that should be monitored for in
this patient?
A. Hypoglycemia
B. Hyperkalemia
C. Hyponatremia
D. Hyperglycemia
