Which of the following does the nurse implement as the most important measure in preventing transmission of harmful pathogens to patients with depressed bone marrow function?

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.

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.
