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: A

Rationale: The correct answer is A: Cataracts. Cataracts are the most common type of vision impairment in older adults due to the clouding of the eye's lens. As people age, proteins in the lens can clump together, leading to vision issues. Glaucoma (B) is characterized by damage to the optic nerve, AMD (C) affects the macula in the retina, and diabetic retinopathy (D) is a complication of diabetes affecting blood vessels in the retina. However, cataracts are the primary cause of vision impairment in older adults due to the natural aging process of the eye.

Correct Answer: B

Rationale: The most effective approach to improve quality of life in older adults with Alzheimer's disease is non-pharmacological interventions like music therapy and structured routines. This is because these interventions have been shown to reduce behavioral symptoms, enhance cognitive function, and promote overall well-being without the potential side effects of pharmacological treatments. Music therapy can help calm and stimulate memory recall, while structured routines provide predictability and familiarity, reducing confusion and agitation. Pharmacological management of behavioral symptoms alone may not address the root causes of the behaviors and can lead to adverse effects. Physical immobilization is harmful and can worsen cognitive decline. Sedatives can have detrimental effects on cognition and may increase the risk of falls and other complications. Therefore, non-pharmacological interventions are the most effective and holistic approach to enhancing the quality of life for older adults with Alzheimer's disease.

Correct Answer: A

Rationale: Step 1: Acknowledge patient's concern. Step 2: Educate on normal aging changes affecting cognitive function. Step 3: Reassure patient that slight delays in tasks are common. Step 4: Encourage healthy habits to support cognitive function. Step 5: Emphasize the importance of monitoring any significant changes. Summary: Choice A is correct as it addresses the concern, educates on normal aging changes, reassures the patient, and provides guidance on monitoring. Choices B, C, and D are incorrect because they either suggest immediate evaluation without considering normal aging changes or provide inaccurate information about brain function in aging.

Correct Answer: C

Rationale: The correct answer is C because gerontological nursing focuses on promoting health and maximizing independence in older adults. This statement aligns with the core principles of gerontological nursing, which emphasize holistic care and quality of life for elderly individuals. Choice A is incorrect because nurses have been involved in caring for older adults for a long time. Choice B is incorrect because gerontological care was not the second specialty certified by the ANA. Choice D is incorrect because ANA certification is not limited only to research positions in gerontological nursing.
