basic geriatric nursing 8th edition test bank

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.

Correct Answer: A

Rationale: The correct answer is A: Decreased manual dexterity and inability to hold a toothbrush. As people age, they may experience decreased hand strength and motor skills, making it difficult to hold and manipulate objects like a toothbrush. This can lead to a decline in oral hygiene practices. Malocclusion of teeth (B) does not directly impact the ability to brush teeth. Decrease in taste acuity (C) may affect appetite but not tooth brushing habits. Lack of dental insurance (D) is a financial barrier and may affect access to dental care, but it does not directly impact the physical ability to brush teeth.

Correct Answer: B

Rationale: The correct answer is B: dehydration. Mr. J's symptoms of flu-like illness, diarrhea, vomiting, confusion, lethargy, dry skin, brown tongue, sunken cheeks, and concentrated urine are indicative of severe dehydration. Dehydration can lead to electrolyte imbalances, decreased blood volume, and impaired organ function, resulting in confusion and lethargy. Skin changes, dry mucous membranes, and concentrated urine are also classic signs of dehydration. The other choices (A, C, D) do not align with the constellation of symptoms presented by Mr. J and are less likely based on the information provided.

Correct Answer: A

Rationale: The correct answer is A: Unsecured scattered rugs. This requires immediate nursing action as it poses a significant fall risk for the older adult. Rugs can cause tripping hazards, leading to potential injuries. The nurse should secure or remove the rugs to ensure the safety of the patient. Summary of other choices: B: Operable smoke detector - While important for safety, it does not require immediate nursing action as it is already in working condition. C: Prefilled medication cassette - This is not an immediate safety concern and can be addressed during routine medication management. D: Unsecured scattered rugs (repeated) - This choice is the same as the correct answer, so it is incorrect.
