NBME 27 Exam Questions and
Answers 100% PASS
defect in development of the first pharyngeal arch leads to?—ANSWER-- hypoplasia of
mandible and micrognathia leading to posterior displacement of the tongue --> airway
obstruction, hypoxia, feeding difficulty, and respiratory distress
**Pierre Robin Syndrome
2nd pharyngeal arch leads to development of?—ANSWER-middle ear, hyoid bone, temporal
styloid process, and muscles including facial muscles, stapedius, platysma, and stylohyoid;
CN VII
3rd pharyngeal arch leads to development of?—ANSWER-stylopharyngeus muscle and
glossopharyngeal nerve (CN IX)
4th pharyngeal arch leads to development of?—ANSWER-cricothyroid muscle and muscles
of soft palate as well as thyroid cartilage; innervated by superior laryngeal branch of vagus
nerve
6th pharyngeal arch leads to development of?—ANSWER-all intrinsic muscles of the larynx
except the cricothyroid muscle, the cricoid, arytenoid, corniculate and cuneiform cartilages;
innervated by laryngeal branch of vagus nerve
hair pulling disorder?—ANSWER-trichotillomania
,**broken hairs are different lengths
alopecia areata—ANSWER-chronic, immune mediated disorder of hair loss
can present with diffuse or focal hair loss
areas may demonstrate smooth or irregular borders
hairs are typically narrower proximally than distally and are prone to breaking
**broken hairs are usually the same length
fibronectin—ANSWER-component of the ECM
**renal mesangial cells grow in a medium that promotes the formation of ECM would be
expected to express increased levels of fibronectin mRNA
main driving force for increased cerebral blood flow is?—ANSWER-increased carbon dioxide
concentration in the blood
clinical signs of hypocalcemia include?—ANSWER-perioral paresthesia, carpopedal spasm,
laryngospasm, and prolonged QT interval
major s/e of beta-adrenergic blockers like propanolol—ANSWER-decreased HR and
contractility, bronchospasm, and hypoglycemia
increased sarcomeres in an array in parallel with each other indicates?—ANSWER-concentric
hypertrophy most commonly d/t HTN and aortic stenosis
**pressure overload
increased sarcomeres in an array in series with each other indicates?—ANSWER-eccentric
hypertrophy most commonly d/t dilated cardiomyopathy

, **volume overload
increased sarcomeres with decreased abundance of F-actin may be seen in?—ANSWER-
genetic cardiomyocyte disorders such as hypertrophic cardiomyopathy
to access the renal arteries from the femoral artery approach, after entering the aorta, the
catheter should be advanced to the area just superior to the take off of?—ANSWER-the
testicular artery
most likely neurologic findings in thrombotic stroke to dominant MCA territory (L side)?—
ANSWER-global aphasia
**d/t involvement of Broca (inferior frontal lobe) and Wernicke (superoposterior temporal
lobe) areas along with arcuate fasciculus (bundle of axons that connects the two areas)
**also CL paralysis and sensory loss (face and upper limb)
most likely neurologic findings in thrombotic stroke to non-dominant MCA territory (R
side)?—ANSWER-CL hemineglect
**also CL paralysis and sensory loss (face and upper limb)
first line agent for GERD, MOA: binds irreversibly to its site of action to inhibit gastric acid
formation?—ANSWER-Esomeprazole
**proton pump inhibitor
**decrease gastric acid secretion by parietal cells through irreversible inhibition of the
H+/K+ ATPase on the luminal surface, which is the primary exporter of hydrogen ions into
the gastric lumen
the ovaries first drain into lymph nodes located?—ANSWER-along the ovarian vessels
