A woman with a diagnosis of type 2 diabetes has been ordered by her primary care provider to have a
hemoglobin A1C test for the first time. The woman states, "I don't see why you want to test my blood
cells when it's sugar that's the problem." What aspect of physiology will underlie the care provider's
response to the patient?
A.)The amount of glucose attached to A1C cells reflects the average blood glucose levels over the life of
the cell.
B)Hemoglobin synthesis by the bone marrow is inversely proportionate to blood glucose levels, with low
A1C indicating hyperglycemia.
C)The high metabolic needs of red cells and their affinity for free glucose indicate the amount of glucose
that has been available over 6 to 12 weeks.
D)Insulin is a glucose receptor agonist on the hemoglobin molecule, and high glucose suggests low
insulin levels. - ANSWER The amount of glucose attached to A1C cells reflects the average blood glucose
levels over the life of the cell.
A 30 year old man with a diagnosis of type 1 diabetes is aware of the multiple effects that insulin has on
his metabolism. Which of the following physiological processes are actions of insulin? - ANSWER

C.) "It's not known exactly why your daughter has completely stopped making insulin, and treatment will
consist of your rigidly controlling her diet."
D.) "The problem that underlies her diabetes is that her own body has destroyed the cells in herpancreas
that produce insulin - ANSWER "The problem that underlies her diabetes is that her own body has
destroyed the cells in her pancreas that produce insulin."

A.) Some chemical substances can function as hormones or be integrated with the central and peripheral

C)Control of body processes is ensured by the fact that a single hormone can only exert one effect on
one specific system or tissue.

Some chemical substances can function as either hormones or neurotransmitters.
What does a high level of thyroid-stimulating hormone indicate?
A.) Thyroid nodule
,B.) Hyperthyroidism
C.) Myxedema
D.) Hypothyroidism - ANSWER Hypothyroidism
Which of the following statements best captures the role of the adrenal cortex in maintaining
homeostasis?
Question 1 options:
A. Normal sexual function is dependent on adequate adrenal cortical function.
B. Redundant, secondary production of adrenal cortical hormones can compensate for the loss of the
adrenal glands.
C. The adrenal cortical hormones are primarily steroids and sex hormones.
D. The adrenal cortex is responsible for the production of epinephrine and norepinephrine, which are
part of the sympathetic nervous system. - ANSWER The adrenal cortical hormones are primarily steroids
and sex hormones.

Which of the following statements best describes an aspect of the normal process of glucose
metabolism?
Question 3 options:
a. Glucose that exceeds metabolic needs is converted and stored by the liver.
b. Blood glucose levels are kept in a steady state by selective excretion and reuptake by the kidneys.
c. Ingested glucose that is not needed for cellular metabolism circulates in the blood until it is taken up
to meet cellular needs.
d. Blood glucose levels are primarily a result of the timing, quantity, and character of food intake. -
ANSWER Glucose that exceeds metabolic needs is converted and stored by the liver.
