A nurse is reinforcing teaching to a client who is to undergo a breast biopsy by needle aspiration. Which of the following statements should the nurse make?

A. Pain level of "4" on a scale of 0 to 10 indicates mild pain and may not require immediate attention compared to other potential issues.
B. Vital signs within normal range, including temperature and blood pressure, do not indicate an urgent need for assessment.
C. Urinary catheter output of 150 mL in the last 3 hours is within the expected range postoperatively and does not require immediate assessment.
D. Saturated perineal pads suggest excessive bleeding, which could indicate a potential complication such as hemorrhage. Therefore, the nurse should assess this patient first to ensure prompt intervention if necessary.

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.
