Mary Jane comes to the clinic concerned about a painless lymph node in the neck. A diagnosis of lymphoma is made. Which of the following would indicate that the lymphoma was Hodgkin lymphoma versus non-Hodgkin lymphoma?

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. Obesity is a common symptom of Cushing syndrome but is not the primary diagnostic criterion. Other tests are needed to confirm the diagnosis.

B. A 24-hour urine collection for cortisol is one of the most common and reliable methods for diagnosing Cushing syndrome. Elevated cortisol levels in the urine are indicative of the syndrome.

C. Chronic renal failure is not related to the diagnosis of Cushing syndrome. While Cushing syndrome may affect renal function, it is not the primary diagnostic tool.

D. Alcoholism can cause symptoms similar to those of Cushing syndrome, but it is not used as a diagnostic criterion. The diagnosis of Cushing syndrome requires specific tests, such as urine cortisol measurement.
