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: A

Rationale: Verbal fluency is the correct answer because reading aloud improves language skills, vocabulary, and verbal expression. It requires cognitive processes like word retrieval, organization, and articulation. Logical analysis (B) is not directly related to reading aloud. Object naming (C) focuses on identifying objects visually, not verbally. Visuospatial skills (D) involve understanding and manipulating visual information, not verbal expression. Reading aloud specifically targets verbal fluency by enhancing communication abilities and language processing.

Correct Answer: C

Rationale: The correct answer is C: 2 years. A case manager typically requires a minimum of 2 years of nursing education to effectively coordinate care for patients. This level of education provides the necessary knowledge and skills to assess, plan, implement, and evaluate patient care. - A: 1 to 1.5 years - Insufficient to acquire the depth of knowledge needed for case management. - B: 4 to 6 years - Excessive for the role of a case manager, as it typically does not require a bachelor's degree. - D: 8 or more years - Overqualified for the position of a case manager, as this level of education is beyond what is necessary for the role.

Correct Answer: B

Rationale: The correct answer is B: Thyroid gland. The thyroid gland produces hormones that regulate metabolism. In older adults, decreased thyroid function, known as hypothyroidism, can lead to a decrease in metabolism. This can result in symptoms such as fatigue, weight gain, and slowed heart rate. A: Kidney - While the kidneys play a role in filtering waste and maintaining fluid balance, decreased kidney function typically does not directly impact metabolism. C: Brain - The brain plays a crucial role in regulating various bodily functions, but it does not directly control metabolism. D: Skeleton - The skeleton provides structural support and protects organs but does not directly influence metabolism.

Correct Answer: B

Rationale: The correct answer is B because a peak flow meter is used to monitor and measure the peak expiratory flow rate, which helps determine if the client is developing asthma symptoms such as airway constriction. It provides feedback on the client's lung function, helping to assess asthma control and guide treatment. Choices A, C, and D are incorrect because a peak flow meter is not used for administering medications, identifying allergy triggers, or limited to specific healthcare professionals.
