,Section 1: Differential Diagnosis & Clinical Reasoning — 2026/2027
Q1 Question 1 of 50
A 52-year-old male presents with exertional chest pain that is relieved by rest after 5 minutes. The
pain does not radiate and is not associated with diaphoresis. The nurse practitioner's initial differential
diagnosis should prioritize
A. Acute myocardial infarction based on the presence of chest pain
B. Stable angina pectoris given the classic pattern of exertional pain relieved by rest
C. Gastroesophageal reflux disease because the pain is non-radiating
D. Costochondritis because there is no diaphoresis
Correct Answer: B
Rationale:
Stable angina is characterized by exertional chest pain relieved by rest within minutes, which matches this
presentation. While acute MI must be ruled out, the relief with rest and absence of associated symptoms favor stable
angina. GERD and costochondritis are less consistent with the exertional trigger.
Q2 Question 2 of 50
A 34-year-old female reports chronic daily headaches that are bilateral, pressing in quality, and not
associated with nausea or vomiting. She denies photophobia or phonophobia. The most likely
diagnosis is
A. Migraine headache because the pain occurs daily
B. Cluster headache because the headaches are chronic and recurrent
C. Sinus headache because the pain is bilateral and pressing
D. Tension-type headache, which is characterized by bilateral pressing pain without nausea or
photo/phonophobia
Correct Answer: D
Rationale:
Tension-type headaches present as bilateral, pressing, or tightening pain of mild to moderate intensity without
nausea and with no more than one of photophobia or phonophobia. Migraines are typically unilateral with nausea and
photophobia. Cluster headaches are strictly unilateral with autonomic symptoms.

, Q3 Question 3 of 50
A 68-year-old male presents with acute onset of severe lower back pain, bilateral leg weakness, and
urinary retention. The nurse practitioner should recognize these findings as potential
A. Lumbar disc herniation manageable with conservative treatment
B. Spinal stenosis that can be managed with physical therapy referral
C. Mechanical low back pain requiring activity modification
D. Cauda equina syndrome requiring emergent MRI and surgical consultation
Correct Answer: D
Rationale:
Cauda equina syndrome is a surgical emergency characterized by severe back pain, bilateral leg weakness, and
bowel or bladder dysfunction. Immediate MRI and neurosurgical consultation are required to prevent permanent
neurological damage. The urinary retention is the red flag distinguishing this from routine disc herniation.
Q4 Question 4 of 50
A 45-year-old female presents with fatigue, weight gain, cold intolerance, and constipation over the
past 3 months. Her TSH is 22 mIU/L and free T4 is low. The most accurate diagnosis is
A. Subclinical hypothyroidism because the symptoms are nonspecific
B. Euthyroid sick syndrome secondary to another systemic illness
C. Hashimoto thyroiditis which can be confirmed by thyroid antibodies
D. Overt hypothyroidism given the elevated TSH, low free T4, and consistent clinical presentation
Correct Answer: D
Rationale:
Overt hypothyroidism is diagnosed by elevated TSH and low free T4 in the setting of consistent symptoms.
Subclinical hypothyroidism features elevated TSH with normal free T4. While Hashimoto thyroiditis is the most
common cause, the current presentation is best described as overt hypothyroidism pending antibody testing.
Q5 Question 5 of 50
A 28-year-old male presents with a 2-week history of low-grade fever, weight loss, night sweats, and
a new murmur. He has a history of intravenous drug use. The nurse practitioner should suspect
A. Infective endocarditis and obtain blood cultures before initiating antibiotics
B. Acute rheumatic fever based on the fever and murmur presentation
C. Viral syndrome with a functional murmur from the febrile state
D. Pulmonary tuberculosis given the night sweats and weight loss
Correct Answer: A
Rationale:
Infective endocarditis should be suspected in an IV drug user presenting with fever, night sweats, weight loss, and a
new murmur. Blood cultures are the critical diagnostic test and must be obtained before antibiotics. While TB shares
some symptoms, the new murmur and IV drug use point toward endocarditis.
