What are clinical manifestations of
hypothyroidism? a. intolerance to
heat, tachycardia, and weight loss
b. oligomenorrhea, fatigue, and warm skin
c. restlessness, increased appetite, and menorrhagia
d. constipation, decreased heart rate, and lethargy -
ANSWER>>*D *The lower levels of TH result in decreased
energy metabolism, resulting in constipation, bradycardia, and
lethargy.
Thyroid-stimulating hormone (TSH) is released to stimulate
thyroid hormone (TH) and is inhibited when plasma levels of TH
are adequate. This is an example of: a. positive feedback
b. neural regulation
c. negative feedback
d. physiologic regulation - ANSWER>>*C
,*Negative feedback occurs because the changing chemical,
neural, or endocrine response to a stimulus negates the initiating
change that triggered the release of the hormone.
Where is antidiuretic hormone (ADH) synthesized and
where does it act? a. hypothalamus, renal tubular cells
b. anterior pituitary, posterior
pituitary
c. renal tubules, renal collecting
ducts posterior pituitary, loop
of henle - ANSWER>>*A
*Once synthesized in the
hypothalamus, ADH acts on
the vasopressin 2 receptors of
the renal duct cells to increase
their permeability.
How does a faulty negative-feedback mechanism result in a
hormonal imbalance? a. hormones are not synthesized in
response to cellular and tissue activities
b. decreased hormonal secretion is a response to rising hormone
levels
c. too little hormone production is initiated
d. excessive hormone production results from a failure to turn off
the system -
ANSWER>>*D
*Negative-feedback systems are important in maintaining
hormones within physiologic ranges. The lack of negative-
feedback inhibition on hormonal release often results in
pathologic conditions. Excessive hormone production, which is
the result of the failure to turn off the system, can cause various
hormonal imbalances and related conditions.
,What imbalance lessens the rate of secretion of
parathyroid hormone a. Increased serum calcium levels
b. Decreased serum magnesium levels
c. Decreased levels of thyroid-stimulating hormone
d. Increased levels of thyroid-stimulating hormone - ANSWER>>*A
*The overall effect of PTH is to increase serum calcium and
decrease serum phosphate. If calcium levels are increased, the
rate of secretion of PTH will be low.
Which condition may result from pressure exerted by a
pituitary tumor? a. Hypothyroidism
b. Diabetes insipidus
c. Hypercortisolism
d. Insulin hypo-secretion - ANSWER>>*A
*If the tumor exerts sufficient pressure, then thyroid and adrenal
hypofunction may occur because of lack of thyroid-stimulating
hormone (TSH) and adrenocorticotropic hormone (ACTH). These
result in the symptoms of hypothyroidism and hypocortisolism.
Graves disease develops from a(n):
a. Viral infection of the thyroid gland that causes
overproduction of thyroid hormone.
b. Autoimmune process during which lymphocytes and fibrous
tissue replace thyroid tissue.
c. Thyroid-stimulating immunoglobulin that causes
overproduction of thyroid hormones.
d. Ingestion of goitrogens that inhibits the synthesis of the
thyroid hormones, causing a goiter. - ANSWER>>*C
, *The pathologic features of Graves disease indicates that normal
regulatory mechanisms are overridden by abnormal immunologic
mechanisms that result in the stimulation of excessive TH.
Pathologic changes associated with Graves disease include:
a. High levels of circulating thyroid-stimulating immunoglobulins
b. Diminished levels of thyrotropin-releasing hormone
c. High levels of thyroid-stimulating hormone
d. Diminished levels of thyroid-binding globulin - ANSWER>>*A
*The only option that correctly describes the changes associated
with Graves disease identifies high levels of circulating thyroid-
stimulating immunoglobulins that are found in more than 95% of
individuals diagnosed with the disease.
The signs of thyrotoxic crisis include:
a. Constipation with gastric distention
b. Hyperthermia and tachycardia
c. Bradycardia and bradypnea
d. Constipation and lethargy - ANSWER>>B
The level of thyroid-stimulating hormone (TSH) in individuals with
Graves disease is usually: a. High
b. Normal
c. Low
d. In constant flux - ANSWER>>*C
*The hyperfunction of the thyroid gland leads to suppression of
TSH because of the normal negative feedback mechanism.
Palpation of the neck of a person diagnosed with Graves disease
would detect a thyroid that is:
