Correct Answer: C

Rationale: The correct answer is C: Increased comfort. Radiation therapy for lung cancer aims to alleviate symptoms, reduce pain, and improve quality of life. It is not typically used as a curative treatment like surgery or chemotherapy (A). It does not prevent the need for oxygen (B), as lung cancer can still affect lung function. While radiation therapy may help control the growth of cancer cells, it is not always effective in preventing cancer spread (D). Therefore, the most appropriate expectation of radiation therapy for lung cancer is increased comfort for the patient.

Correct Answer: D

Rationale: The correct answer is D: Administer pain medication. The priority in this situation is to address the patient's pain and provide relief. Administering pain medication will help alleviate the discomfort and enable the patient to mobilize with crutches or a walker. Walking without pain is crucial for the patient's recovery. Explanation for other choices: A: Assisting the patient to walk with crutches may worsen the pain and should not be attempted until the pain is managed. B: Obtaining a walker is not the priority as the immediate concern is addressing the patient's pain. C: Consulting physical therapy may be beneficial in the long term, but immediate pain relief is the priority in this situation.

Correct Answer: B

Rationale: Rationale: 1. Discharge planning should start at admission to ensure comprehensive preparation. 2. Early planning allows for assessment of needs and coordination of resources. 3. It promotes continuity of care and reduces risks of readmission. 4. Options A, C, and D are incorrect as they miss the opportunity for proactive planning.

Correct Answer: B

Rationale: The correct answer is B: Turn on the affected side. This position helps to promote the closure of the puncture site in the lung, reducing the risk of fluid leakage and pneumothorax. Placing the client flat in bed (A) may not allow gravity to assist in the closure of the puncture site. Turning on the unaffected side (C) may not effectively prevent fluid leakage from the puncture site. Bed rest (D) is a general instruction and does not specifically address the prevention of fluid leakage after thoracentesis.

Correct Answer: B

Rationale: The correct answer is B: 7th cranial nerve. Bell's palsy is caused by inflammation of the facial nerve (7th cranial nerve), leading to facial muscle weakness or paralysis. The 3rd cranial nerve (choice A) controls eye movement, the 5th cranial nerve (choice C) is responsible for facial sensation and chewing, and the 8th cranial nerve (choice D) is related to hearing and balance. Bell's palsy specifically affects the facial muscles, making choice B the correct answer.
