Correct Answer: B

Rationale: The correct answer is B: Increased risk of falls. Benzodiazepines are central nervous system depressants that can cause drowsiness, dizziness, and impaired coordination, leading to an increased risk of falls in older adults. This is due to the sedative effects of benzodiazepines, which can affect balance and motor skills. Increased alertness (choice A) is not a common side effect of benzodiazepines, as they typically have a calming and sedating effect. Improved memory (choice C) is also unlikely, as benzodiazepines are more commonly associated with memory impairment. Enhanced muscle strength (choice D) is not a known side effect of benzodiazepines, as they do not directly affect muscle strength. In summary, the correct answer is B because benzodiazepines can increase the risk of falls in older adults due to their sedative properties.

Correct Answer: C

Rationale: The correct answer is C because regular repositioning and the use of pressure-relieving devices are essential to prevent skin breakdown in immobile older adults. Repositioning helps redistribute pressure, maintaining blood flow to the skin and preventing tissue damage. Pressure-relieving devices such as cushions or special mattresses further reduce pressure on vulnerable areas. Choices A and B do not address the root cause of skin breakdown and may even exacerbate the issue. Choice D is incorrect as complete bed rest can lead to further complications like pressure ulcers. In summary, choice C is the most effective intervention as it directly targets the risk factors for skin breakdown in immobile older adults.

Correct Answer: B

Rationale: The correct answer is B: Benzodiazepines. Benzodiazepines are central nervous system depressants that can cause drowsiness, dizziness, and confusion, increasing the risk of falls in older adults. They can also impair balance and coordination. Older adults are more sensitive to these effects due to age-related changes in metabolism and increased risk of cognitive impairment. Beta-blockers (A), statins (C), and antihypertensives (D) are generally safe in older adults and do not directly increase the risk of falls. Beta-blockers can sometimes cause dizziness but are more commonly associated with bradycardia. Statins are used to lower cholesterol levels and do not affect fall risk. Antihypertensives help lower blood pressure and can actually reduce the risk of falls by preventing conditions like orthostatic hypotension.

Correct Answer: B

Rationale: The correct answer is B: Malnutrition and dehydration. Malnutrition and dehydration are major risk factors for pressure ulcers in older adults because they can lead to poor skin integrity, reduced tissue resilience, and impaired wound healing. Lack of sleep (choice A) may contribute to overall health issues but is not a direct risk factor for pressure ulcers. Excessive physical activity (choice C) can increase the risk of injury but does not directly cause pressure ulcers. High blood pressure (choice D) is a risk factor for cardiovascular issues but is not specifically linked to the development of pressure ulcers.

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.
