Correct Answer: B

Rationale: The correct answer is B: The patient should be monitored for bone marrow depression. Carbamazepine can cause bone marrow suppression, leading to decreased production of blood cells. Monitoring blood counts is crucial to detect this adverse effect early. Choice A is incorrect as Tegretol can have serious adverse effects, including bone marrow depression. Choice C is incorrect as the main side effects of carbamazepine are related to the central nervous system, not renal dysfunction. Choice D is incorrect as medications like carbamazepine should be started at a low dose and gradually titrated up to minimize side effects.

Correct Answer: B

Rationale: The correct answer is B. By asking the patient to demonstrate the instillation of medications, the nurse can directly assess the patient's ability to self-administer the medications safely and effectively. This method allows for a practical demonstration of skills, which is more reliable than relying solely on verbal descriptions or past experiences. Choices A, C, and D are incorrect because assessing for previous inability, describing the method, or evaluating functional status may not directly demonstrate the patient's competency in self-administering ocular medications.

Correct Answer: B

Rationale: The correct answer is B: Sleep on a firm mattress. A firm mattress helps maintain proper spinal alignment, reducing pressure on the cervical spine. This promotes healing and prevents worsening of symptoms. A: Performing active ROM exercises may exacerbate symptoms and worsen the condition. C: Applying cool compresses may provide temporary relief but does not address the underlying issue of spinal alignment. D: Wearing a cervical collar for extended periods can weaken neck muscles and hinder natural healing processes. In summary, sleeping on a firm mattress is the most appropriate conservative measure as it supports proper spinal alignment.

Correct Answer: C

Rationale: The correct answer is C: Apply petroleum jelly to the affected area. This is because petroleum jelly helps to soothe and protect the skin, reducing dryness and irritation caused by radiation therapy. Ice (A) can further damage the skin, shaving (B) can increase the risk of infection, and soap (D) can be too harsh on the sensitive skin. Therefore, instructing the patient to apply petroleum jelly is the most appropriate recommendation to promote skin healing and comfort.

Correct Answer: A

Rationale: The correct answer is A: Testicular cancer is a highly curable type of cancer. This is the most appropriate point to emphasize because early detection through regular self-examinations can lead to early treatment and a high survival rate. Testicular cancer has a very high cure rate, especially when detected and treated early. Emphasizing this point encourages boys to perform monthly self-exams, leading to early detection and better outcomes. Explanation of other choices: B: Testicular cancer is very difficult to diagnose - This is incorrect because testicular cancer is actually one of the more easily detectable cancers through self-examinations. C: Testicular cancer is the number one cause of cancer deaths in males - This is incorrect as testicular cancer is not the leading cause of cancer deaths in males. D: Testicular cancer is more common in older men - This is incorrect as testicular cancer is more common in younger men, typically between the ages of 15 and 44.
