Adult Health Nursing Study Guide Answers

Correct Answer: A

Rationale: Total knee arthroplasty (TKA), also known as total knee replacement, is a surgical procedure commonly performed to alleviate symptoms and improve function in patients with advanced osteoarthritis of the knee that has not responded to conservative management. During TKA, the damaged cartilage and bone in the knee joint are removed and replaced with prosthetic components. This procedure aims to reduce pain, restore function, and improve the quality of life for individuals with severe osteoarthritis of the knee. High tibial osteotomy (HTO) is typically performed in younger patients with unicompartmental osteoarthritis, while knee arthroscopy and meniscectomy are more targeted towards specific knee conditions and may not provide significant relief in cases of advanced osteoarthritis.

Correct Answer: B

Rationale: Cervical intraepithelial neoplasia (CIN) is a precancerous condition of the cervix characterized by the presence of abnormal cells on the surface of the cervix. These abnormal cells are often classified as low-grade squamous intraepithelial lesions (LSIL) on cytology. CIN is not yet cervical cancer but can progress to invasive cancer if left untreated. LSIL is indicative of mild dysplasia or cervical intraepithelial neoplasia 1 (CIN 1), which is considered a precancerous lesion. Therefore, the presence of abnormal cervical cells classified as LSIL is more likely to be associated with CIN rather than cervical cancer, cervicitis, or cervical polyps.

Correct Answer: D

Rationale: The clinical presentation of chest pain, dyspnea, and a friction rub heard on auscultation is suggestive of pericarditis. The diffuse ST-segment elevation seen on the electrocardiogram (ECG) is a classic finding in pericarditis, known as the "universal sign." In contrast, stable angina typically presents with chest pain on exertion that is relieved by rest or nitroglycerin, while unstable angina presents with chest pain at rest or with minimal exertion. Acute myocardial infarction would typically present with ST-segment elevation in specific leads correlating with the area of myocardial ischemia/infarction. However, in the context of diffuse ST-segment elevation and symptoms suggestive of inflammation (friction rub), the most likely diagnosis is pericarditis.

Correct Answer: A

Rationale: Task A, obtaining special food for the patient when she requests it, can be delegated to the nursing assistant. This task involves simple assistance with gathering food items and does not require specific medical knowledge or interventions. Tasks B, C, and D involve more direct patient care and assessment, which should be performed by the nursing staff who have the necessary training and expertise to address the complexities of anorexia nervosa.

Correct Answer: B

Rationale: In order to create a comprehensive education plan, the nurse must include all of the listed components.
