Which condition is often misdiagnosed as depression in older adults?

Correct Answer: B

Rationale: The correct answer is B: Dementia. Older adults often experience cognitive decline, memory loss, and behavioral changes that can be mistaken for symptoms of depression. Dementia is a common condition in the elderly that can be misdiagnosed due to overlapping symptoms such as apathy, social withdrawal, and changes in sleep patterns. Chronic fatigue syndrome (A), anemia (C), and sleep apnea (D) may also present with symptoms of fatigue and sleep disturbances, but they are less likely to be confused with depression in older adults compared to dementia.

Correct Answer: B

Rationale: The correct answer is B because limited physical activity and poor nutrition have been consistently linked to cognitive decline in older adults. Physical activity promotes blood flow to the brain, which helps with cognitive function. Additionally, a balanced diet rich in nutrients supports brain health. Genetic predisposition (A) can play a role but is not the most closely associated factor. Social engagement and mental stimulation (C) are beneficial for cognitive health but not the primary factor for decline. Early retirement and lack of work-related stress (D) are not directly linked to cognitive decline.

Correct Answer: B

Rationale: The correct answer is B: Cognitive decline affecting memory and decision-making. Older adults with cognitive impairments, such as dementia, may struggle with remembering to take their medications as prescribed and making sound decisions regarding their medication regimen due to cognitive decline. Memory deficits can lead to missed doses, while impaired decision-making can result in improper adherence. Choices A, C, and D are incorrect as the primary reason for medication non-adherence in this population is the cognitive decline impacting memory and decision-making, rather than lack of understanding, physical inability, or fear of side effects.

Correct Answer: B

Rationale: The correct answer is B because multimorbidity refers to the presence of multiple chronic conditions in an individual, which can complicate treatment due to interactions between medications, conflicting treatment recommendations, and the need for coordination among different healthcare providers. Managing multiple health conditions and medications can lead to potential adverse effects, drug interactions, and difficulties in prioritizing treatment goals. Choices A, C, and D are incorrect because multimorbidity actually increases treatment complexity, necessitating individualized care plans and careful consideration of potential interactions between treatments.

Correct Answer: D

Rationale: The correct answer is D because sarcopenia, which is the age-related loss of muscle mass and strength, directly impacts balance and mobility in older adults. Muscle weakness from sarcopenia reduces stability and coordination, increasing the risk of falls. This affects functional independence as it limits the ability to perform daily activities safely. Choices A, B, and C are incorrect as sarcopenia primarily affects muscle mass and strength, not body fat, lung capacity, or joint stiffness.
