Rationale: The rationale for instructing the patient to apply benzene hexachloride (Lindane) in small quantities for scabies treatment is that excessive applications can lead to central nervous system toxicity. Lindane is a neurotoxin, and overuse or incorrect application can result in adverse effects on the central nervous system, such as seizures, dizziness, and even death. Choices B, C, and D are incorrect because they do not reflect the specific toxic effects associated with Lindane, which primarily affects the central nervous system rather than causing skin irritation, gastrointestinal symptoms, or metabolic issues.

These large abnormal cells have a bi-lobed or multi-lobed nucleus and are essential for diagnosing Hodgkin lymphoma through histological examination. Merkel cells are associated with Merkel cell carcinoma, Schwann cells are related to nerve sheaths, and Kupffer cells are liver macrophages. Therefore, choices A, B, and D are incorrect for Hodgkin lymphoma.

Correct Answer: A

Rationale: The correct answer is A, Romberg test. The Romberg test is used to assess balance and proprioception. During the test, the client is asked to stand with feet together, eyes open, and hands by the sides to observe their balance. Then, the client is asked to close their eyes while the nurse continues to observe for a full minute. This test helps in detecting any issues with proprioception and balance, which may be compromised in conditions affecting the nervous system. Choices B, C, and D are incorrect because the Weber test is used to assess hearing in each ear, the Rinne test is used to compare air and bone conduction of sound, and the Babinski test is used to assess the integrity of the corticospinal tract.

Rationale: The correct answer is A: Reduction in prostate size and improvement in urinary symptoms. Finasteride works by reducing the size of the prostate gland, which in turn helps alleviate urinary symptoms such as frequency, urgency, weak stream, and incomplete emptying of the bladder. Choice B is incorrect as while finasteride can improve urine flow indirectly by reducing prostate size, it does not directly increase urine flow. Choice C is incorrect because finasteride is not intended to improve erectile function. Choice D is incorrect as finasteride does not primarily provide relief from pain associated with BPH.
