Medical Surgical HESI

Correct Answer: D

Rationale: The correct answer is D: Compression of a nerve. In carpal tunnel syndrome, pain arises from the compression of the median nerve within the carpal tunnel. This compression leads to symptoms such as pain, numbness, and tingling in the hand and arm. Choices A, B, and C are incorrect because carpal tunnel syndrome pain is primarily caused by the physical compression of the nerve, rather than irritation of nerve endings, diminished blood flow, or ischemic tissue changes.

Correct Answer: B

Rationale: The correct answer is B: Long-term chemotherapy. In the case of acute lymphoblastic leukemia, the most effective approach for maintaining remission is long-term chemotherapy, particularly with methotrexate, a chemotherapeutic agent. Surgery to remove enlarged lymph nodes (choice A) is not the primary treatment for leukemia. Nutritional supplements (choice C) may be beneficial for overall health but are not the mainstay of leukemia treatment. Blood transfusions (choice D) are used to manage anemia in leukemia but do not address the underlying disease process.

Correct Answer: A

Rationale: The best teaching for the nurse to provide is to invite friends over regularly to share meal times. This can help in making meal times more enjoyable for the client with Parkinson's disease, potentially encouraging him to eat more. Encouraging clear liquids between meals (choice B) may not address the underlying issue of weight loss. Coaching the client to make an intentional effort to swallow (choice C) may not be effective if the weight loss is due to other factors related to Parkinson's disease. While prescribing an appetite stimulant (choice D) could be an option, it is usually recommended to explore non-pharmacological interventions first, making choice A the most appropriate initial teaching intervention.

Correct Answer: B

Rationale: The correct answer is B: Oranges. Oranges are not a rich source of iron. Iron-rich foods include liver, leafy green vegetables, and kidney beans. Oranges are a good source of vitamin C but are not high in iron. Therefore, if the client selects oranges as an iron-rich food, it indicates a need for additional instructions on choosing foods high in iron.

Correct Answer: D

Rationale: Instructing the client in the use of the PCA pump is the best initial nursing action for managing severe incisional pain after knee replacement surgery. The PCA pump allows the client to self-administer pain medication effectively, promoting better pain management. Administering a sedative may mask the pain temporarily but doesn't address the root cause. Repositioning the client for comfort or applying ice packs may provide some relief but doesn't address the need for effective pain control as the PCA pump does.
