year-old male. His hemoglobin levels are 15.5 g/dL. Would this be
considered a normal or abnormal value? Answer: Normal
◍ You are reading results from a recent blood panel for Susan, a 48-
year-old female. Her hemoglobin levels are 7 g/dL. Would this be
considered a normal or abnormal value? Answer: Abnormal. Normal
Hemoglobin levels for a female is 12-15 g/dL
◍ You are reading results from a recent blood panel for Jane, a 37-
year-old female. Her hemoglobin levels are 13 g/dL. Would this be
considered a normal or abnormal value? Answer: Normal
◍ Which are true of the mitochondria? Select all that apply. Answer:
It is involved in cellular respiration
They play a role in apoptosis
◍ Which is NOT true of the cytoskeleton? Answer: It includes
peroxisomes and proteasomes
◍ Which of the following is an active form of Vitamin D? Answer:
25-hydroxycholecalciferol
,◍ Which of the following is an inactive form of Vitamin D? Answer:
Cholecalciferol
◍ Which of the following is synthesized in the kidney and regulates
the differentiation of red blood cells within bone marrow? Answer:
Erythropoietin
◍ Which are true of the cell membrane? Select all that apply. Answer:
Controls the transport of materials from the outside fluids to within
Helps with the conduction of electrical currents in nerve and muscle
cells
Aids in the regulation of cell growth and proliferation
◍ True or False. If false, explain why the statement is false.
A benign neoplasm invades and destroys tissue and possesses a rapid
rate of growth. Answer: False. A malignant neoplasm invades and
destroys tissues and possesses a rapid rate of growth.
OR
A benign neoplasm resembles the cells of the tissues of origin and
possesses a slow rate of growth.
◍ True or False. If false, explain why the statement is false.
A malignant neoplasm resembles the cells of the tissues of origin and
possesses a slow rate of growth. Answer: False. A benign neoplasm
resembles the cells of the tissues of origin and possesses a slow rate of
growth.
OR
, A malignant neoplasm invades and destroys tissue and possesses a
rapid rate of growth.
◍ List 2 differences between benign and malignant neoplasms.
Answer: Any combination of the following - Benign tumors are well-
differentiated cells, resemble the cells of tissues of origin, and have a
slow, progressive rate of growth. They grow by expansion and remain
localized to their site of origin, not capable of metastasizing.
Malignant neoplasms invade and destroy tissue. They grow rapidly,
spread to other parts of the body, and lack well- defined margins.
They can compress blood vessels and outgrow their blood supply,
causing ischemia and tissue injury.
◍ Compare and contrast the two types of gangrenous necrosis.
Answer: In dry gangrene the affected tissue becomes dry and shrinks,
the skin wrinkles, and its color changes to dark brown or black. The
spread of dry gangrene is slow. It results from a cut-off in arterial
blood supply and is a form of coagulation necrosis. In wet gangrene,
the affected area is cold, swollen, and pulseless. The skin is moist,
black, and under tension. Blebs form on the surface, liquefaction
occurs, and a foul odor is caused by bacterial action. The spread of
tissue damage is rapid.
◍ You are talking to your patient who has been recently diagnosed
with Osteoporosis. They mentioned that they joined a Silver Sneakers
program at their local gym because they read that weight-bearing
exercise promotes bone density. What word of caution would you
give to them as they participate in this program? Answer: While
weight-bearing exercises have been shown to increase bone density,
