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: A

Rationale: The correct answer is A: Pneumonia. Older adults are more susceptible to pneumonia due to weakened immune systems and other health conditions. Pneumonia can lead to severe complications requiring hospitalization. Stroke (B) affects a significant number of older adults but is not the leading cause of hospitalization. Diabetes (C) and Congestive heart failure (D) are prevalent in older adults but are not the primary reason for hospitalization. Pneumonia's severity and impact on older adults' health make it the leading cause of hospitalization.

Correct Answer: B

Rationale: The correct answer is B: The culture has a different orientation to time than Western medicine. This is because the patient's statement about not following up on appointments due to cultural reasons suggests a difference in the perception and importance of time. In some cultures, time is more fluid and flexible compared to the rigid scheduling of Western medicine. This understanding helps the nurse provide culturally sensitive care. Choices A, C, and D are incorrect: A: The culture does not value Western medicine - This is not necessarily implied by the patient's statement about cultural differences. C: The culture is an interdependent culture - The patient's statement does not provide direct evidence of the culture being interdependent. D: The culture does not believe in preventative care - There is no indication in the patient's statement that the culture does not believe in preventative care.

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: A

Rationale: The correct answer is A: Promoting wellness. Providing information about diet and exercise for a healthy diabetic client falls under promoting wellness because it focuses on proactive measures to maintain health and prevent complications. It aims to empower the client to make healthy lifestyle choices. B: Preventing illness is not the best description as the client is already diabetic, so the focus is on managing the condition rather than solely preventing it. C: Treating disease is not accurate because the client is already diabetic and the goal is not to treat the disease, but rather manage it effectively. D: Restoring health is not applicable in this scenario as the client is not in a state of compromised health that needs to be restored.
