Correct Answer: A

Rationale: The correct answer is A because one of the hallmark symptoms of Parkinson's disease is bradykinesia, which is characterized by slowness of movement. This symptom commonly presents as a person moving far more slowly than usual. Option B is more indicative of arthritis or another musculoskeletal condition. Option C suggests possible cognitive decline or dementia, not specific to Parkinson's disease. Option D could indicate a different medical condition causing weight loss despite a good appetite. Therefore, A is the most suggestive of Parkinson's disease based on the symptom of bradykinesia.

Correct Answer: B

Rationale: The correct answer is B: Cholesteatoma. A red blemish behind the tympanic membrane is indicative of a cholesteatoma, which is a noncancerous cyst in the middle ear. This occurs due to the accumulation of skin cells and debris in the middle ear space. Other choices (A, C, D) are not associated with a red blemish on otoscopy. An acoustic tumor (A) typically presents as a slow-growing mass on the vestibulocochlear nerve. Facial nerve neuroma (C) involves the facial nerve and does not typically cause a red blemish. Glomus tympanicum (D) is a vascular tumor arising from the middle ear but does not usually present as a red blemish.

Correct Answer: A

Rationale: The correct answer is A: Information about this disease. The Huntington's Disease Society of America provides valuable resources such as educational materials, support groups, and updates on research. This information can help patients and families understand the disease better and navigate available treatment options. Referrals, public education, individual assessments, and appraisals of research studies are not typically services provided directly by the organization, making them incorrect choices in this context.

Correct Answer: D

Rationale: The correct answer is D: Dispose of the antineoplastic wastes in the hazardous waste receptacle. This is crucial to prevent exposure to potentially harmful substances. Here's the rationale: 1. Antineoplastic agents are hazardous chemicals that can harm individuals and the environment. 2. Proper disposal in a hazardous waste receptacle ensures safety and compliance with regulations. 3. Options A, B, and C are incorrect as adjusting doses based on symptoms, hand hygiene, and personal protective equipment are important but not as critical as proper disposal of hazardous waste in this context.

Correct Answer: D

Rationale: The correct answer is D: Surgical intervention. Cataracts are a clouding of the lens in the eye, which can lead to vision impairment. Surgery is the most common and effective treatment for cataracts, involving the removal of the cloudy lens and replacement with an artificial one. Antioxidant supplements (Choice A) may help prevent cataracts but are not a treatment for existing ones. Eyeglasses or magnifying lenses (Choice B) can help with vision correction but do not address the cataracts themselves. Corticosteroid eye drops (Choice C) are used for treating inflammation in the eye, not cataracts. Therefore, surgical intervention is the most appropriate treatment option for age-related cataracts.
