A mother brings in her 8-month-old child to the ER. The mother reports the baby has recently started being extremely fussy, has a fever, and swelling in the hands and feet. The child is diagnosed with sickle cell disease. As the nurse, you know that the swelling in the hands and feet in the infant is termed?

A. Given the low hemoglobin level and weight, the patient is likely experiencing fatigue due to decreased oxygen-carrying capacity of the blood, leading to activity intolerance.
B. While weight loss may contribute to body image disturbance, it is not the primary concern for a patient with iron-deficiency anemia and low hemoglobin levels.
C. Anxiety related to the hospital environment may be present, but it is not the most appropriate nursing diagnosis based on the patient's clinical presentation and laboratory findings.
D. Impaired tissue integrity related to immobility is not the most appropriate nursing diagnosis for a patient with iron-deficiency anemia. This diagnosis is more commonly associated with pressure ulcers or skin breakdown in patients who are immobile for extended periods, which is not described in this scenario.

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.
