Physiology-11
A 20-year-old woman admits herself to the
emergency room with a yellow discoloration of
the whites of her eyes. She says that she does
not drink and that she has not experienced any
changes in her stool. Her liver enzyme profile
and direct serum bilirubin levels are normal,
while total bilirubin is elevated. What is the
most likely cause for her jaundice?
(A) defect in hepatocytes
(B) defect in Kupffer cells
(C) gallstones
(D) hemolysis
(E) tumor obstructing bile duct

With increasing age, it is quite common for
adults to have very low sensitivity for highpitch
sounds. Which of the following physiologic
responses occur as the pitch of a sound is
increased at constant sound pressure?
(A) a greater number of hair cells become
activated
(B) the amplitude of maximal basilar membrane
displacement increases
(C) the frequency of action potentials in
auditory nerve fibers increases
(D) the location of maximal basilar membrane
displacement moves toward the
cochlear base
(E) units in the auditory nerve become
responsive to a wider range of sound
frequencies

For the bithermal caloric test, a measure of
vestibular sensitivity, warm or cold water is
introduced into the ear. This often causes vertigo
and nausea as a side effect as a result of
which of the following?
(A) convection currents in endolymph
(B) especially fast flow of endolymph
(C) temporary immobilization of cristae
ampullares
(D) temporary immobilization of otolith
organs
(E) temporary inhibition of cochlear hair
cells

A very thin 15-year-old female presents with
headache, polyuria, and grand mal seizures.
She answers the question, if she has had to
vomit recently, with “frequently” but that these
symptoms “are under control now.” Her body
mass index is 14.1. Serum glucose, calcium, and
potassium are normal. Serum sodium, chloride,
and osmolarity are low. As a working diagnosis,
which of the following is most likely?
(A) Addison disease
(B) central diabetes insipidus
(C) diabetes mellitus
(D) nephrogenic diabetes insipidus
(E) water intoxication

A 34-year-old male is brought into the emergency
room, having been found unconscious in
his apartment. Apparently, he has been in this
state for 2 days. The laboratory values for the
patient’s blood and urine are consistent with
elevated circulating antidiuretic hormone
(ADH). Which one of the following will
directly stimulate ADH in this patient?
(A) angiotensinogen
(B) extracellular fluid osmolality increase
(C) temperature decrease
(D) thyroid hormone
(E) volume increase
