Correct Answer: C

Rationale: The correct answer is C because loss of vision in one eye is not a typical sign or symptom of Parkinson's disease. A, B, and D are all common signs of Parkinson's disease. A - Mask-like facial expressions result from decreased facial muscle movement. B - Shuffling gait is a characteristic walking pattern in Parkinson's patients. D - Tremors without intention (at rest) are a classic symptom of Parkinson's disease due to disrupted brain signals. Therefore, C is the odd one out as it is not directly associated with Parkinson's disease manifestations.

Correct Answer: B

Rationale: The correct answer is B because social isolation is not directly related to decreased tactile sensations. A, C, and D are consequences of decreased tactile sensations in older individuals. A can occur due to not feeling the temperature, C due to not feeling pressure and injury, and D due to decreased sensation causing falls. Social isolation is more related to emotional or psychological factors rather than physical sensations. It is crucial to differentiate between physical consequences and social consequences when considering the effects of decreased tactile sensations in older individuals.

Correct Answer: A

Rationale: The correct answer is A: Regular repositioning every 2 hours. Repositioning helps to relieve pressure on vulnerable areas, improving blood flow and preventing tissue damage. This intervention is evidence-based and recommended in pressure ulcer prevention guidelines. Administering pain medications before repositioning (B) does not address the root cause of pressure ulcers. Encouraging excessive hydration (C) may have other health benefits but does not directly prevent pressure ulcers. Using restrictive bandages (D) can actually increase pressure and worsen the risk of pressure ulcers.

Correct Answer: C

Rationale: The correct answer is C because regular repositioning every 2 hours, along with the use of pressure-relieving devices, is the most effective intervention to prevent pressure ulcers in older adults with limited mobility. Repositioning helps to redistribute pressure, reducing the risk of tissue damage. Pressure-relieving devices like cushions or mattresses further help to alleviate pressure points. Choice A is incorrect because strict bed rest and minimal repositioning can actually increase the risk of pressure ulcers by concentrating pressure on specific areas. Choice B is incorrect as high-protein diets and supplements alone do not address the primary cause of pressure ulcers, which is prolonged pressure on the skin. Choice D is incorrect because leaving wounds uncovered can increase the risk of infection and hinder the healing process.

Correct Answer: C

Rationale: The correct answer is C: 90 y.o woman with advanced Parkinson's dz. Older adults with advanced Parkinson's disease are more vulnerable to abuse due to their physical and cognitive impairments. They may be dependent on caregivers, making them easy targets for abuse. The other choices do not indicate significant vulnerability to abuse. Choice A is a common demographic but lacks specific vulnerability factors. Choice B with cataracts and Choice D with early Lyme disease do not inherently increase the risk of abuse.
