When the parents of a 6-year-old boy with a brain tumor are told that his condition is terminal, the mother shouts at the father, "This is your fault! It never would have happened if we had sought treatment sooner!" Which intervention is best for the nurse to implement?

The clinical scenario involves postoperative management of a surgical site in a patient colonized with methicillin-resistant Staphylococcus aureus. Successful intervention requires applying principles of wound hygiene, bacterial proliferation kinetics, and aseptic technique to mitigate localized moisture which fosters rapid staphylococcal replication and subsequent infection.

Choice A rationale: Elevated white blood cell counts, typically exceeding 11,000 mm3, indicate a systemic inflammatory response or active infection. While monitoring hematologic data is essential for detection, it is a reactive measure rather than a proactive intervention to prevent localized MRSA recurrence.

Choice B rationale: Contact precautions prevent the horizontal transmission of resistant pathogens between the patient and others. While vital for institutional infection control and public health safety, these measures do not directly address the localized physiological environment of the patient's own surgical incision.

Choice C rationale: Saturated dressings create a warm, moist environment that facilitates capillary action, pulling contaminants into the wound. Maintaining a dry, sterile environment inhibits the colonization of methicillin-resistant Staphylococcus aureus, as moisture promotes the rapid exponential growth of these resistant gram-positive cocci.

Choice D rationale: Face masks primarily provide protection against respiratory droplet transmission. While beneficial for preventing the introduction of oropharyngeal flora into a sterile field, they are less critical than moisture control for preventing MRSA recurrence, which is primarily spread through direct or indirect contact.

Imbalanced Nutrition: less than body requirements would be the nursing problem with the highest priority for an adolescent with anorexia nervosa. Anorexia nervosa is characterized by a severe restriction of food intake leading to a significantly low body weight, which can have serious physical and psychological consequences. Therefore, addressing the client's malnutrition and promoting adequate nutrition intake is crucial to prevent further complications. Disturbed Body Image, Interrupted Family Processes, and Noncompliance with treatment regimen are important nursing problems to address, but they are secondary to the client's malnutrition.
