Inflammation is ultimately needed to:

A. When performing hand hygiene, the hands should be held lower than the elbows to allow water to flow downward, preventing the contamination of the forearms.

B. The water temperature should be warm, but not hot, to prevent skin irritation. Extremely hot water is not necessary for effective hand hygiene.

C. Hands and arms should be rubbed together to create friction during hand washing. However, drying should be done with a clean paper towel or air dryer, not by rubbing the hands and arms together.

D. The correct amount of liquid soap for hand hygiene is typically 4 to 5 mL. This is the appropriate amount to ensure effective coverage and cleaning of the hands.

A. Atherosclerosis, the buildup of fatty plaques in the arteries, is a common cause of death in patients with progeria. These patients experience accelerated aging, which leads to early development of cardiovascular diseases, including atherosclerosis, which contributes to their early mortality.

B. Psychosis is not typically associated with progeria. The condition primarily affects physical aging processes rather than causing psychiatric symptoms like psychosis.

C. While rapid aging is the hallmark of progeria, it is not the direct cause of death. Instead, it leads to the development of age-related diseases like cardiovascular issues, which are the main contributors to mortality.

D. Scleroderma is a condition involving the hardening of the skin and connective tissues, but it is not a direct cause of death in progeria. The primary cause of death is related to cardiovascular complications such as atherosclerosis.
