The healthcare provider prescribes 500 mL intravenous (IV) bolus of 0.9% normal saline to be infused over 30 minutes. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only.)

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.

The correct answer/s is Choice/s A, C, and E.

Choice A rationale: Obtaining the client’s tympanic temperature measurement is a crucial step. The client’s confusion and disorientation could be symptoms of an infection, such as a urinary tract infection or pneumonia. Infections in older adults can often present with atypical symptoms, including changes in mental status. Therefore, checking the client’s temperature can help identify if the client has a fever, which is a common sign of an infection.

Choice B rationale: While it’s always important to be aware of a client’s allergies, especially when administering medications, it doesn’t directly address the immediate concern of the client’s altered mental status. Therefore, it’s not the most appropriate action to take in response to the situation described.

Choice C rationale: Asking if the client is experiencing any pain with urination is relevant because urinary tract infections (UTIs) are common in older adults and can cause confusion and other changes in mental status. Pain during urination is a common symptom of a UTI.

Choice D rationale: Encouraging the intake of high protein foods is generally a good recommendation for older adults to maintain their strength and energy levels. However, it’s not directly related to the client’s current symptoms of confusion and disorientation.

Choice E rationale: Determining if the client has recently experienced a fall is important. Falls in older adults can lead to injuries, such as a head injury, which can cause confusion and other changes in mental status. Additionally, some medications used to treat pain after a fall can also contribute to confusion.
