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?
Creation of a "sterile" environment for the patient with the use of laminar airflow rooms
Placement of patients in private rooms with high-efficiency particulate air (HEPA) filtration
Strict and frequent handwashing by all people having contact with the patient
Administration of combinations of prophylactic antibiotics
The Correct Answer is C
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. Elevated blood pressure above 140/90. While hypertension can occur in middle age, it is not specifically associated with perimenopause.
B. Report of dryness with vaginal intercourse. Vaginal dryness is a common symptom of perimenopause due to decreasing estrogen levels.
C. Report of urinary retention. Urinary symptoms in perimenopause more commonly include frequency and urgency, rather than retention.
D. Elevated body temperature above 37.8° C (100° F). While hot flashes are common during perimenopause, they do not typically cause a sustained elevated body temperature.

B. Cyanosis refers to a bluish discoloration of the skin due to poor circulation or inadequate oxygenation, which is not directly indicative of red blood cell destruction.
C. Jaundice is the yellowing of the skin and eyes caused by the buildup of bilirubin, a byproduct of the destruction of red blood cells, which is a common symptom of hemolytic anemia.
D. Bleeding is not a symptom associated with the destruction of red blood cells but rather a lack of clotting factors or platelets.
