Correct Answer: A

Rationale: The most appropriate intervention for managing ventilator-associated pneumonia (VAP) caused by multidrug-resistant organisms (MDROs) is to administer combination antibiotic therapy targeting the specific resistant pathogens identified in the patient's culture results. MDROs are often resistant to multiple antibiotics, so combination therapy is required to maximize the chances of effectively treating the infection. Identifying the specific pathogens causing the VAP through cultures is crucial in tailoring the antibiotic therapy to target these organisms effectively. Implementing appropriate antibiotic therapy promptly is essential to improve outcomes and prevent further complications in patients with VAP caused by MDROs. Option A is the priority intervention in this case to address the multidrug-resistant nature of the infection and provide targeted treatment for the patient.

Correct Answer: A

Rationale: The primary indicator that Nurse Mary observes FIDELITY in the practice of her profession is that she faithfully promotes health and prevents disease. Fidelity in nursing practice refers to being faithful, loyal, and committed to providing the best care and services to patients. By faithfully promoting health and preventing disease, Nurse Mary demonstrates her dedication to her profession, her patients, and the community she serves. This commitment includes following evidence-based practices, upholding ethical standards, being honest and trustworthy, and ensuring the well-being of those under her care. Ultimately, fidelity in nursing practice builds trust and confidence among patients, families, and colleagues, leading to better health outcomes and a stronger healthcare system.

Correct Answer: B

Rationale: The presentation of a painful, vesicular rash in a dermatomal distribution on the left thorax, specifically in a patient with a history of chickenpox, is most suggestive of herpes zoster, commonly known as shingles. Herpes zoster is caused by the reactivation of the varicella-zoster virus, the same virus responsible for chickenpox. After a person recovers from chickenpox, the virus remains dormant in the nerve cells and can reactivate years later to cause shingles. The rash in herpes zoster typically progresses through different stages, including red patches leading to fluid-filled blisters. The characteristic rash typically appears unilaterally and is usually preceded by pain, burning, or tingling in the affected area. Unlike herpes simplex virus infection, which can cause similar lesions but is not typically localized to a specific dermatome, herpes zoster presents as a distinct unilateral cluster of vesicles along

Correct Answer: C

Rationale: When a patient is at risk of falls due to an impaired gait, a physical therapist would be the most appropriate member of the multidisciplinary team for the nurse to collaborate with. Physical therapists specialize in improving mobility, balance, and coordination through exercises, gait training, and other interventions. They can assess the patient's gait pattern, strength, and balance, and develop a personalized plan to address the impairments contributing to the fall risk. By working closely with a physical therapist, the nurse can help the patient improve their gait and reduce the risk of falls, ultimately promoting safety and independence.

Correct Answer: A

Rationale: In a patient with acute kidney injury (AKI) secondary to sepsis in the ICU, the healthcare team should prioritize initiating continuous veno-venous hemofiltration (CVVH) for renal replacement therapy. CVVH is a form of continuous renal replacement therapy that helps support renal function by removing waste products, excess fluids, and electrolytes from the blood while providing hemodynamic stability. This intervention is crucial in managing fluid overload, electrolyte disturbances, and uremia associated with AKI in critically ill patients. It can also help improve overall outcomes and prevent further complications related to renal dysfunction in this setting. Administering diuretics, implementing fluid restriction, or performing a renal biopsy may not directly address the acute renal failure and may not provide the necessary renal support needed in this urgent situation.
