1. A 45-year-old male presents to the advanced practice clinic complaining of a progressive,
dull, aching pain in his right upper quadrant over the past three weeks, accompanied by
low-grade fever and mild jaundice. Laboratory results show an elevated alkaline
phosphatase and gamma-glutamyl transferase (GGT). Which of the following is the most
likely primary diagnosis to investigate using abdominal ultrasonography?
A. Acute appendicitis
B. Acute cholecystitis
C. Acute pancreatitis
D. Acute viral gastroenteritis
Answer: B
Biliary tract pathology such as acute cholecystitis frequently presents with right upper
quadrant pain, fever, and jaundice, alongside markers of cholestasis like elevated alkaline
phosphatase and GGT. Ultrasonography is the preferred initial imaging modality to assess for
gallstones, gallbladder wall thickening, and pericholecystic fluid.
2. A 62-year-old female with a history of hypertension and type 2 diabetes presents for a
routine annual comprehensive health assessment. She reports no acute complaints, but her
blood pressure in the office is 158/94 mmHg, confirmed on a repeat measurement after five
minutes. According to current evidence-based advanced practice guidelines, what is the
most appropriate next step in clinical management?
A. Initiate dual-agent antihypertensive therapy immediately and schedule a follow-up in one
month
B. Order an immediate 24-hour ambulatory blood pressure monitoring test before initiating
any lifestyle changes
C. Initiate lifestyle modifications and begin a single first-line antihypertensive medication while
scheduling a recheck in four weeks
D. Reassure the patient that isolated clinic elevations are benign and recheck blood pressure in
one year
Answer: C
For a patient with a confirmed stage 2 hypertension reading (systolic $\ge$ 140 or diastolic
$\ge$ 90 mmHg) and cardiovascular risk factors like diabetes, current guidelines recommend
,initiating lifestyle modifications and starting pharmacologic therapy with a single first-line
agent, accompanied by a short-interval follow-up.
3. During a physical examination of a 55-year-old male, the advanced practice registered
nurse notes a pulsating midline abdominal mass measuring approximately 5.5 cm in
diameter upon deep palpation. The patient is completely asymptomatic. What is the most
critical and appropriate immediate course of action?
A. Reassure the patient, document a normal variant, and monitor yearly via physical exam
B. Order an urgent contrast-enhanced abdominal computed tomography (CT) scan and refer
immediately to vascular surgery
C. Prescribe a beta-blocker to reduce blood pressure and schedule a routine outpatient
ultrasound in six months
D. Perform an aggressive deep abdominal massage to map the exact borders of the mass
Answer: B
A pulsatile midline abdominal mass measuring 5.5 cm or greater strongly indicates an
abdominal aortic aneurysm (AAA) at high risk for rupture. Urgent diagnostic imaging via CT
angiography and prompt surgical consultation are mandatory to evaluate for immediate
intervention.
4. A 28-year-old female presents with acute onset sharp left-sided pleuritic chest pain and
shortness of breath that began suddenly this morning. She takes oral contraceptives and
recently completed a 12-hour cross-country flight. Her heart rate is 115 beats per minute,
and her oxygen saturation is 92% on room air. Which diagnostic tool should be prioritized
first to stratify her risk for pulmonary embolism?
A. D-dimer blood assay combined with a validated clinical prediction rule such as the Wells
criteria
B. Immediate invasive pulmonary angiography without prior non-invasive testing
C. Routine 12-lead electrocardiogram to look exclusively for S1Q3T3 patterns
D. Transthoracic echocardiogram to assess right ventricular hypertrophy
Answer: A
For a patient presenting with suspected pulmonary embolism with low-to-moderate clinical
probability, utilizing a validated clinical decision rule like the Wells score alongside a high-
sensitivity D-dimer test is the standard and efficient initial approach for risk stratification.
5. A 70-year-old male presents with progressive, painless jaundice, dark urine, and pale
stools over the past month. He also reports a 15-pound unintentional weight loss. Physical
examination reveals a palpable, non-tender gallbladder in the right upper quadrant
(Courvoisier's sign). Which underlying malignancy must be suspected first?
,A. Hepatocellular carcinoma
B. Pancreatic head adenocarcinoma
C. Chronic gastric ulceration
D. Splenic marginal zone lymphoma
Answer: B
Painless jaundice accompanied by weight loss and a palpable, non-tender gallbladder
(Courvoisier's sign) is a classic presentation of a malignant obstruction of the biliary tree,
most commonly adenocarcinoma originating in the head of the pancreas.
6. A 50-year-old premenopausal female presents with a distinct, firm, mobile, and non-
tender breast mass in the upper outer quadrant of her left breast, discovered during self-
examination. She has no family history of breast cancer. What is the most appropriate next
step in diagnostic evaluation?
A. Diagnostic bilateral mammography and targeted breast ultrasonography
B. Immediate radical mastectomy without prior tissue confirmation
C. Reassurance and instruction to return only if the lump doubles in size within one month
D. Empiric prescription of broad-spectrum oral antibiotics for suspected mastitis
Answer: A
Any newly discovered discrete breast mass in a patient over the age of 30 warrants prompt
diagnostic imaging evaluation, which combines diagnostic mammography with targeted
ultrasonography to differentiate between cystic and solid lesions.
7. A 35-year-old male presents with chronic, recurrent heartburn, acid regurgitation, and a
chronic dry cough that worsens when lying flat after meals. Standard over-the-counter
antacids provide only temporary relief. Which advanced diagnostic test is considered the
gold standard for confirming gastroesophageal reflux disease (GERD) when empiric
therapy fails or complications are suspected?
A. Upper gastrointestinal barium swallow series
B. 24-hour ambulatory esophageal pH monitoring
C. Routine fasting serum gastrin levels
D. Diagnostic diagnostic diagnostic abdominal ultrasound
Answer: B
Ambulatory 24-hour esophageal pH monitoring evaluates esophageal acid exposure over a
full day and is considered the gold standard diagnostic test for confirming GERD, especially in
cases of refractory symptoms or before surgical intervention.
, 8. An 81-year-old nursing home resident is evaluated for acute confusion and lethargy.
Staff report she has been increasingly withdrawn and uncommunicative for two days. Her
temperature is 38.3 degrees Celsius, pulse is 102 beats per minute, and urinalysis reveals
positive leukocyte esterase, nitrites, and numerous bacteria. What is the most accurate
overarching assessment category for her presentation?
A. Uncomplicated viral upper respiratory infection
B. Hospital-acquired pneumonia with sepsis
C. Complicated urinary tract infection manifesting as delirium in an elderly patient
D. Acute exacerbation of chronic obstructive pulmonary disease
Answer: C
Elderly patients frequently present with atypical symptoms of urinary tract infections, such as
acute delirium, lethargy, and functional decline, rather than classic dysuria or frequency.
Positive urinalysis markers confirm the infectious etiology.
9. A 22-year-old college student presents with a three-day history of severe sore throat,
profound fatigue, posterior cervical lymphadenopathy, and low-grade fever. Physical
examination reveals tonsillar enlargement with a grayish-white exudate and mild
splenomegaly. Which diagnostic test is most specific for confirming the suspected
diagnosis?
A. Rapid streptococcal antigen detection swab
B. Heterophile antibody test (Monospot) or Epstein-Barr virus (EBV) serology
C. Complete blood count demonstrating marked basophilia
D. Throat culture for Neisseria gonorrhoeae
Answer: B
The clinical triad of severe pharyngitis, fatigue, and lymphadenopathy, combined with
splenomegaly and exudative tonsillitis, points toward infectious mononucleosis caused by the
Epstein-Barr virus, confirmed via heterophile antibody testing or EBV-specific serology.
10. A 40-year-old female presents with recurrent episodes of symmetric joint stiffness in
her hands and wrists lasting more than one hour each morning, accompanied by fatigue
and low-grade fevers. Physical examination reveals swelling and tenderness of the
metacarpophalangeal and proximal interphalangeal joints. Which laboratory marker is
most sensitive and specific for establishing a diagnosis of rheumatoid arthritis?
A. Serum uric acid level
B. Anti-cyclic citrullinated peptide (anti-CCP) antibodies
C. Antinuclear antibody (ANA) titer alone
D. Erythrocyte sedimentation rate (ESR) without autoantibodies
