Which blood cells are the chief phagocytes involved in the early
inflammation process? a. Neutrophils
b. Eosinophils
c. Monocytes
d. Erythrocytes - CORRECT ANSWER✔✔ A
Which blood cells are biconcave in shape and have the capacity to be
reversibly deformed? a. Neutrophils
b. Eosinophils
c. Monocytes
d. Erythrocytes - CORRECT ANSWER✔✔ *D
*The erythrocyte's size and shape are ideally suited to its function as a gas
carrier. A red blood cell (RBC) is a small disk with two unique properties: (1)
a biconcave shape and (2) the capacity to be reversibly deformed.

What is the life span of an erythrocyte (in days)? a.
20 to 30
b. 100 to 120
c. 60 to 90
d. 200 to 240 - CORRECT ANSWER✔✔ *B
*Because it cannot undergo mitotic division, the erythrocyte has a limited
life span of approximately 120 days.
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 - CORRECT 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
,3 | Page
b. neural regulation
c. negative feedback
d. physiologic regulation - CORRECT 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 - CORRECT 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 - CORRECT ANSWER✔✔ *D
, 4 | Page
*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 - CORRECT 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 - CORRECT ANSWER✔✔ *A
