When positioning the patient after a total hip arthroplasty with a posterior approach, it is important that the nurse maintain the affected extremity in what position?

Correct Answer: B

Rationale: The correct answer is B) Abduction and extension. After a total hip arthroplasty with a posterior approach, maintaining the affected extremity in abduction helps prevent dislocation of the hip prosthesis. Extension is important to keep the hip from flexing beyond 90 degrees, which could also lead to dislocation. Option A) Adduction and flexion would increase the risk of hip dislocation as it brings the hip into a position that could easily pop the prosthesis out of place. Option C) Abduction and internal rotation could lead to impingement or instability of the hip joint. Option D) Adduction and external rotation also increase the risk of hip dislocation. In an educational context, understanding the proper positioning after hip arthroplasty is crucial for nursing practice to prevent complications and promote patient safety and recovery. Nurses must be knowledgeable about postoperative care interventions to provide optimal care for patients undergoing orthopedic surgeries like hip arthroplasty.

Correct Answer: D

Rationale: The correct answer to the NCLEX question on laboratory findings in a patient with RA is option D) anti-citrullinated protein antibody (ACPA). ACPA is a specific marker for rheumatoid arthritis (RA) and its presence in the blood indicates an autoimmune response that is characteristic of RA. This antibody is highly specific for RA and is used in the diagnosis of the disease. Option A) polycythemia is incorrect because it is characterized by an increase in red blood cell count, which is not typically associated with RA. Option B) increased immunoglobulin G (IgG) is also incorrect as elevated IgG levels are not specific to RA and can be seen in a variety of conditions. Option C) decreased white blood cell (WBC) count is not a typical finding in RA as RA is not primarily a disease of decreased WBCs. Educationally, understanding the specific laboratory findings associated with RA is crucial for nurses caring for patients with this condition. Being able to interpret these findings can aid in early diagnosis and appropriate management of RA. Nurses need to be familiar with the diagnostic markers for RA to provide comprehensive care and support to patients with autoimmune diseases.

Correct Answer: A

Rationale: The correct answer is A) Destruction of nucleic acids and other self-proteins by autoantibodies. Systemic lupus erythematosus (SLE) is an autoimmune disease where the body's immune system mistakenly attacks its own tissues. In SLE, autoantibodies target nucleic acids and other self-proteins, leading to tissue damage and inflammation. This pathophysiology results in a wide range of manifestations affecting multiple organ systems. Option B) Overproduction of collagen that disrupts the functioning of internal organs is incorrect because this describes a mechanism more closely associated with conditions like systemic sclerosis, not SLE. Option C) Formation of abnormal IgG that attaches to cellular antigens, activating complement is incorrect as this mechanism is more aligned with diseases like autoimmune hemolytic anemia, not SLE. Option D) Increased activity of T suppressor cells with B-cell hypoactivity, resulting in an immunodeficiency is incorrect as SLE is characterized by hyperactivity, not hypoactivity, of B cells and a breakdown in immune tolerance. Understanding the pathophysiology of SLE is crucial for nurses and other healthcare professionals to recognize its varied presentations and provide appropriate care. By grasping the autoimmune nature of SLE, healthcare providers can better tailor treatment plans and educate patients on self-management strategies to improve outcomes.
