NR 507Final exam questions and correct answers.
Question 1
Which hormone prompts increased anxiety, vigilance, and arousal during a stress response?
Correct! 3339
Norepinephrine
orepinephrin
Norepinephrine
Only the release of norepinephrine promotes arousal, increased vigilance, increased anxiety, and other
protective emotional responses.
Question 2
pts
Idiopathic thrombocytopenic purpura (ITP) is an autoimmune process involving antibodies attacking
which type of cells?
Platelets
Platelets
ITP is a disorder of platelet consumption. This selection is the only option that correctly identifies which
type of cell is attacked by ITP.
Question 3
When renin is released, it is capable of which action?
Formation of angiotensin I
Formation o
Formation of angiotensin I
,NR 507Final exam questions and correct answers.
When renin is released, it cleaves an α-globulin (angiotensinogen produced by liver hepatocytes) in the
plasma to form angiotensin I.
Question 4
Which of the following are formed elements of the blood that are not cells but are disk-shaped
cytoplasmic fragments essential for blood clotting?
Platelets
Platelets
Platelets
Platelets (thrombocytes) are not true cells but are disk-shaped cytoplasmic fragments that are essential
for blood coagulation and control of bleeding. This description is not accurate for any of the other
options.

Question 5
In a full-term infant, the normal erythrocyte life span is days, whereas the adult erythrocyte
life span is days.
60 to 80; 120
60 to 80; 12
In full-term infants, normal erythrocyte life span is 60 to 80 days; in premature infants it may be as
short as 20 to 30 days; and in children and adolescents, it is 120 days, the same as that in adults.
Question 6
pts
,NR 507Final exam questions and correct answers.
Graves disease is a result of:
Autoantibodies binding to thyroid-stimulating hormone (TSH)-receptor sites
Autoantibod
In the hyperthyroidism (excessive thyroid activity) of Graves disease, autoantibody binds to and activates
receptors for TSH (a pituitary hormone that controls the production of the hormone thyroxine by the
thyroid). The other options do not accurately describe the cause of Graves disease.
Question 7
What is the most commonly reported symptom of cancer treatment?
Fatigue
Fatigue
Fatigue
Fatigue is the most frequently reported symptom of cancer and cancer treatment. Although patients
report the other options, they are not as frequently experienced as fatigue.
Question 8
In which structure does B lymphocytes mature and undergo changes that commit them to becoming B
cells?
Bone marrow
Bone marro
, NR 507Final exam questions and correct answers.
Bone marrow
B lymphocytes mature and become B cells in specialized (primary) lymphoid organs—the thymus gland
for T cells and the bone marrow for B cells. Neither regional lymph nodes nor the spleen are involved
in changing B lymphocytes into B cells.
Question 9
Chvostek and Trousseau signs indicate which electrolyte imbalance?
Hypocalcemia
Hypocalcem
Hypocalcemia
Two clinical signs of hypocalcemia are the Chvostek sign and Trousseau sign. These clinical signs are
not indicative of any of the other options.
Question 10
On average, what percent of cardiac output do the kidneys receive?
20% to 25%
20% to 25%
20% to 25%
The kidneys are highly vascular organs and usually receive 1000 to 1200 ml of blood per minute, or
approximately 20% to 25% of the cardiac output.
