basic geriatric nursing 8th edition test bank

Correct Answer: C

Rationale: The correct answer is C because a room with hardwood floor and large windows overlooking a garden area offers a safe, non-slip surface for exercise and natural light for a pleasant environment. Hardwood floors are ideal for exercise to prevent slipping, and the large windows provide a view of the garden area, which can enhance motivation and mood. The other choices are incorrect because A has throw rugs, which can cause tripping hazards, B lacks natural light and ventilation, and D has a linoleum floor which may not be as safe for exercise compared to hardwood.

Correct Answer: B

Rationale: The correct answer is B because older adults have reduced kidney function, which impairs their ability to concentrate urine and retain water. Additionally, they may have a diminished thirst sensation, making them less likely to drink enough fluids. This combination of factors makes older adults more vulnerable to dehydration compared to younger adults. Choice A is incorrect because older adults actually have a lower percentage of body water due to age-related changes in body composition. Choice C is incorrect as dehydration can indeed have a more significant impact on older adults due to their physiological changes. Choice D is incorrect as older adults are actually more prone to dehydration due to various age-related factors.

Correct Answer: D

Rationale: The correct answer is D: Circulatory problems related to age and a chronic illness. Severe edema, hair loss on the legs, and foot ulcerations are indicative of poor circulation, often seen in conditions like peripheral artery disease. Age and chronic illnesses can contribute to circulatory issues. A diet low in protein (choice A) would not directly cause these symptoms. Exposure to cold (choice B) would not explain the specific symptoms mentioned. Frequent falls (choice C) do not align with the symptoms provided.

Correct Answer: D

Rationale: The correct answer is D: Confusion or cognitive decline. In older adults, dehydration can manifest differently than in younger populations. Cognitive decline is a key sign of dehydration in older adults due to the brain being more sensitive to fluid loss. Dehydration can lead to confusion, disorientation, and impaired cognitive function in older individuals. Dark-colored urine (A) is a common sign of dehydration in all age groups. Increased thirst (B) is a general sign of dehydration but may not be as prominent in older adults due to decreased thirst sensation. Dry mouth and skin (C) are also common signs of dehydration but may not be as reliable indicators in older adults compared to cognitive changes.

Correct Answer: B

Rationale: The correct answer is B: high likelihood of orthostatic hypotension upon rising quickly. Orthostatic hypotension is a common issue in the elderly, causing a sudden drop in blood pressure when standing up quickly, leading to dizziness and falls. This factor directly contributes to the high incidence of falls in the elderly. Increased muscle mass and tone (A) actually reduce the risk of falls, while improving eyesight in dim light (C) would decrease the risk. Constipation (D) is not directly related to falls in the elderly.
