Aplastic anemia is a disorder in which the bone marrow cells that develop into mature blood cells become damaged. The damaged bone marrow cells can lead to low numbers of red blood cells, white blood cells, and/or platelets. When the cause of aplastic anemia cannot be diagnosed, the cause is likely which of the following?

Radiation exposure

An autoimmune disorder

Chemotherapy drugs

Toxins

Answer and Explanation

The Correct Answer is B

A.   Radiation exposure: Radiation exposure can cause aplastic anemia, but if the cause is unknown, it is less likely to be due to a specific and identifiable event like radiation exposure.
B.   An autoimmune disorder: When the cause of aplastic anemia cannot be diagnosed, it is often attributed to an autoimmune disorder where the body attacks its own bone marrow cells.
C.   Chemotherapy drugs: Chemotherapy drugs can cause aplastic anemia, but this cause would typically be known based on the patient's medical history.
D.   Toxins: Toxins can cause aplastic anemia, but like chemotherapy drugs and radiation, this cause would generally be identifiable.

Correct Answer is ["A","B","D","E"]

Explanation

A. Feeling for changes in the underarm area is important as breast tissue extends into this region and lumps can form there.
B. Since menopausal women do not have periods, they can perform BSE at any consistent time each month to help remember to do it regularly.
C. Pressing the breasts too firmly could cause discomfort and is not necessary for detecting lumps.
D. Performing BSE in the shower is effective because the soapy water allows the fingers to move smoothly over the skin.
E. Using fingertips is the proper technique for checking breasts, as it allows for more sensitivity in detecting changes in the breast tissue.

A. Decreased production of clotting factors B. Impaired platelet function C. Excessive activation of clotting factors and widespread clot formation D. Excessive platelet production

Correct Answer is C

Explanation

A. DIC is not characterized by decreased production of clotting factors. Instead, it involves consumption of clotting factors due to widespread activation of coagulation.
B. While platelet dysfunction may occur in DIC due to consumption and depletion of platelets, the primary pathophysiological process in DIC is the activation of clotting factors and formation of blood clots throughout the vasculature.
C. Excessive activation of clotting factors and widespread clot formation is the primary pathophysiological process in DIC. This leads to the formation of numerous small blood clots throughout the body's blood vessels, resulting in organ dysfunction and potentially life-threatening complications.

D. Excessive platelet production is not a characteristic feature of DIC. Instead, platelets are consumed and depleted as they are incorporated into the blood clots formed during the
coagulation cascade in DIC.
