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: D

Rationale: Negligence is the failure to take proper care in doing something, which results in harm or injury to someone else. In this scenario, the client falling out of bed because side rails were not used indicates a lack of proper care or attention by the staff or caregiver responsible for the client. It shows a failure to protect the client from harm, which aligns with the definition of negligence. This situation does not fit the definitions of a felony, battery, or assault.

Correct Answer: C

Rationale: Sudden, severe chest pain and dyspnea in a postpartum client could be indicative of a potential serious condition, such as a pulmonary embolism or postpartum cardiomyopathy, which require immediate medical attention. Therefore, the most appropriate nursing action would be to notify the healthcare provider immediately for further evaluation and management. Placing the client in a semi-Fowler's position may provide some comfort but does not address the underlying cause of the symptoms. Administering supplemental oxygen therapy may be necessary once the healthcare provider assesses the client. Encouraging deep breathing exercises may not be appropriate if the client is experiencing severe chest pain and dyspnea, as it could worsen the situation.

Correct Answer: A

Rationale: Bulimia nervosa is an eating disorder characterized by binge eating followed by compensatory behaviors such as self-induced vomiting, fasting, or excessive exercise. The repeated purging in bulimia can lead to electrolyte imbalances, such as hypokalemia (low potassium levels). Hypokalemia is a serious condition that can affect the function of the heart's electrical system, potentially leading to the development of cardiac arrhythmias (irregular heartbeats) and even cardiac arrest, which can result in death. Therefore, in a bulimic patient like Sherry, the risk of death is most likely due to the combination of hypokalemia and its complications, such as cardiac arrhythmias and arrest.

Correct Answer: C

Rationale: In this scenario, the action that violates a psychiatric patient's rights is option C, where staff members confiscated written letters done by patients addressed to the local newspaper. Patients have the right to communicate freely and express their thoughts and feelings through various means, such as letter-writing. Confiscating these letters is a violation of their rights to free expression and communication. It is essential to respect and uphold the rights of psychiatric patients, including their right to communicate with others.
