QUESTION 1
A 55yearold patient presents to the emergency department with the sudden onset of
the worst headache of their life, described as a "thunderclap" headache. The
patient has no significant medical history but reports a family history of
aneurysms. Which condition is most likely responsible for this presentation?
A. Migraine with aura
B. Subarachnoid hemorrhage
C. Tension headache
D. Temporal arteritis
E. Cluster headache
✓ Correct Answer: B
Rationale: Subarachnoid hemorrhage is caused by rupture of a berry (saccular)
aneurysm, presenting with sudden, severe "thunderclap" headache, often described
as the worst headache of the patient's life. Risk factors include hypertension,
smoking, and family history of aneurysms. Immediate neuroimaging and
neurosurgical consultation are critical.
QUESTION 2
A 28yearold male involved in a highspeed motor vehicle accident presents with
bilateral periorbital ecchymosis, clear rhinorrhea from the nose, and bruising
behind the ears. The nurse recognizes these findings as most consistent with which
diagnosis?
A. Subdural hematoma
B. Epidural hematoma
C. Basilar skull fracture
D. Diffuse axonal injury
E. Concussion
, ✓ Correct Answer: C
Rationale: Basilar skull fracture is characterized by 'Raccoon eyes' (periorbital
ecchymosis), CSF otorrhea or rhinorrhea, and Battle's sign (mastoid ecchymosis).
These findings indicate a fracture at the base of the skull, which may involve the
cribriform plate or temporal bone, requiring prompt neurosurgical evaluation.
QUESTION 3
A 35yearold male of Mediterranean descent presents with fatigue, pallor, and
jaundice after eating a meal containing fava beans. Laboratory studies reveal
hemolytic anemia with bite cells and Heinz bodies on peripheral blood smear.
Which enzyme deficiency is most likely responsible for this patient's presentation?
A. Pyruvate kinase deficiency
B. Glucose6phosphate dehydrogenase deficiency
C. Aldolase deficiency
D. Hexokinase deficiency
E. Enolase deficiency
✓ Correct Answer: B
Rationale: G6PD deficiency is identified by bite cells and Heinz bodies on blood
smear and causes hemolytic anemia after fava bean ingestion, certain medications
(sulfonamides, antimalarials), or infections. This Xlinked disorder affects the
pentose phosphate pathway, reducing protection against oxidative stress in red
blood cells.
QUESTION 4
A 48yearold female with a history of Graves' disease who underwent thyroidectomy
2 days ago now presents with fever of 103°F, tachycardia, confusion, nausea, and
vomiting. Which condition should the healthcare team suspect?
A. Myxedema coma
B. Thyroid storm
,C. Adrenal crisis
D. Hypoglycemic shock
E. Septic shock
✓ Correct Answer: B
Rationale: Thyroid storm occurs in a patient with hyperthyroidism who develops
fever, tachycardia, confusion, and vomiting, often triggered by surgery, infection,
trauma, or discontinuation of antithyroid medications. This lifethreatening
condition requires immediate treatment with betablockers, antithyroid drugs, and
supportive care.
QUESTION 5
A pregnant woman undergoes routine prenatal screening, and her amniotic fluid
analysis reveals an elevated alphafetoprotein level. The nurse understands that this
finding raises concern for which fetal condition?
A. Down syndrome
B. Neural tube defect
C. Cystic fibrosis
D. Turner syndrome
E. Klinefelter syndrome
✓ Correct Answer: B
Rationale: The main concern with elevated AFP in a pregnant woman's amniotic
fluid is a neural tube defect such as spina bifida. Elevated AFP can also indicate
abdominal wall defects, multiple gestations, or incorrect dating, but neural tube
defects are the most significant concern requiring further evaluation with
ultrasound.
QUESTION 6
A 22yearold female presents with fatigue, jaundice, and splenomegaly. Laboratory
studies show spherocytes on peripheral smear, increased osmotic fragility, and a
negative Coombs test. Which diagnosis is most consistent with these findings?
, A. Autoimmune hemolytic anemia
B. Hereditary spherocytosis
C. Sickle cell anemia
D. Thalassemia major
E. G6PD deficiency
✓ Correct Answer: B
Rationale: Hereditary spherocytosis is diagnosed with spherocytes, increased
osmotic fragility, and a negative Coombs test. This autosomal dominant condition
results from defects in red blood cell membrane proteins (ankyrin, spectrin),
causing spherical red blood cells that are more susceptible to splenic destruction
and hemolysis.
QUESTION 7
A 32yearold male presents with chronic low back pain that improves with exercise
and worsens with rest. He also reports a history of uveitis. Physical examination
reveals decreased chest expansion. Which condition is associated with this
presentation and HLAB27 positivity?
A. Rheumatoid arthritis
B. Osteoarthritis
C. Ankylosing spondylitis
D. Psoriatic arthritis
E. Reactive arthritis
✓ Correct Answer: C
Rationale: Ankylosing spondylitis is associated with HLAB27 positivity, low back
pain that improves with exercise, and uveitis. This inflammatory
spondyloarthropathy affects the sacroiliac joints and spine, leading to decreased
chest expansion, spinal fusion, and characteristic radiographic findings of
"bamboo spine."
