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.

Correct Answer: B

Rationale: Tiotropium (Spiriva) is an anticholinergic bronchodilator used for the management of COPD. A common side effect of anticholinergic medications is dry mouth. Rinsing the mouth with water after using the inhaler can help reduce the risk of developing oral thrush or other mouth infections due to dryness. This instruction helps promote good oral hygiene and decreases the potential side effects associated with tiotropium inhaler use. This teaching is important for patients to follow to ensure their overall health and well-being while using the medication.

Correct Answer: C

Rationale: Mrs. Juan's therapeutic treatment should focus on redirecting her energy into activities that involve helping others. By engaging in altruistic activities, Mrs. Juan can shift her focus away from her fears and anxieties towards something positive and fulfilling. This approach can help her to find purpose and meaning outside of her own concerns, fostering a sense of well-being and satisfaction. Additionally, helping others can provide Mrs. Juan with a sense of accomplishment and self-worth, ultimately contributing to her overall mental health and emotional resilience.

Correct Answer: B

Rationale: Avascular necrosis of the femoral head, also known as osteonecrosis, is a common complication associated with hip fractures in elderly patients. It occurs when there is a loss of blood supply to the femoral head following the fracture, leading to bone tissue death. This can result in pain, limitation of motion, and potentially the collapse of the femoral head, causing further complications. Timely diagnosis and appropriate management are crucial in order to prevent further degeneration of the hip joint. Other complications such as compartment syndrome, dislocation of the hip prosthesis, and Volkmann's contracture are not typically associated with hip fractures in elderly patients.

Correct Answer: D

Rationale: An advance directive is a legal document that specifies a person's healthcare preferences and instructions for medical treatment in the event they are unable to communicate their wishes. It typically includes decisions about life-sustaining treatments, resuscitation, and end-of-life care. In the scenario provided, the document provided by the patient to the nurse outlining his healthcare team's instructions postoperatively indicates that he has an advance directive in place to guide his medical care if necessary. In contrast, informed consent is a process in which a patient gives permission for medical treatment after being informed about the risks, benefits, and alternatives. Patient's Bill of Rights outlines the patient's rights within the healthcare system, and an insurance card provides information about the patient's insurance coverage.
