Which of the following is a characteristic feature of hemophilia?

A. Decreased serum albumin is not typically associated with hemolysis; it may occur in conditions such as liver disease or malnutrition.
B. Jaundice, or yellowing of the skin and eyes, is a common manifestation of hemolysis due to the increased production of bilirubin from the breakdown of red blood cells.
C. Increased serum bilirubin levels occur as a result of hemolysis, contributing to the development of jaundice.
D. Increased bilirubin is essentially the same as increased serum bilirubin; both indicate the presence of jaundice due to hemolysis.
E. Presence of dark urine is also characteristic of hemolysis, as it may contain excess bilirubin, giving it a darker color.

A. Creation of a "sterile" environment with laminar airflow rooms is not practical or necessary for preventing transmission of pathogens to patients with depressed bone marrow function. It may also not be feasible in many healthcare settings.
B. Placement of patients in private rooms with HEPA filtration may help reduce airborne pathogens but is not the most important measure for preventing transmission of harmful pathogens to patients with depressed bone marrow function.
C. Strict and frequent handwashing by all people having contact with the patient is the most important measure for preventing transmission of harmful pathogens, including bacteria and viruses, to immunocompromised patients. Hand hygiene is a fundamental infection control measure that significantly reduces the risk of healthcare-associated infections.
D. Administration of prophylactic antibiotics may be part of the treatment plan for some patients with depressed bone marrow function to prevent bacterial infections, but it is not the most important measure for preventing transmission of harmful pathogens. Hand hygiene is more effective in reducing the transmission of a wide range of pathogens, including bacteria, viruses, and fungi.
