OR
A malignant neoplasm invades and destroys tissue and possesses a rapid rate of
growth.
List 2 differences between benign and malignant neoplasms. -Correct 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. -Correct 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? -Correct Answer ✔While
weight-bearing exercises have been shown to increase bone density, they should be
done in a safe way, minimizing the risk for falls as they are at increased risk for fracture
with a diagnosis of osteoporosis.
You are talking to your patient who has been recently diagnosed with Osteoporosis.
They mention to you that they are doing safe, weight bearing exercises each day to
increase bone density. They are also taking a Calcium supplement. What additional
supplement would you recommend they take? Explain why. -Correct Answer ✔They
should also take a Vitamin D supplement, as it helps to increase calcium absorption.
You are talking to your patient who has been recently diagnosed with
Osteoporosis. You have suggested that they start taking Calcium and Vitamin D daily.
What else can you recommend to slow the progression of this disease? -Correct
Answer ✔You should recommend regular weight-bearing exercises to increase bone
density. This should be done in a safe manner minimizing the risk for falls.
(The key is safety. Weight-bearing exercises done safely is the best answer, but
exercise done in a way that minimizes risk of fractures is the key. Exercises done safely
as an answer should receive full credit.)

specialized cell types. -Correct Answer ✔False, cell differentiation
True/False: Cell differentiation is the process of increasing cell numbers by mitotic cell
division. -Correct Answer ✔False, cell proliferation
