What is the most common cause of delirium in hospitalized older adults?

Correct Answer: C

Rationale: The correct answer is C: Urinary tract infections (UTIs). UTIs are a common cause of delirium in hospitalized older adults due to their impact on the central nervous system. UTIs can lead to systemic inflammation and affect cognitive function, resulting in delirium. Other choices like medication side effects, sleep deprivation, and electrolyte imbalances can contribute to delirium but are not as common or direct as UTIs in this population.

Correct Answer: C

Rationale: Certainly! Regular strength training exercises are crucial for improving strength and overall function in older adults with frailty. Strength training helps build muscle mass, improve balance, and increase mobility, leading to enhanced functional abilities. It also helps prevent falls and maintain independence. High-protein diet (A) supports muscle health but alone is not sufficient. Medication management (B) is important but not the primary factor for physical function. Limiting physical activity (D) can worsen frailty by causing deconditioning and loss of muscle strength.

Correct Answer: D

Rationale: The correct answer is D: Complicated medication regimens. Older adults often have multiple medical conditions requiring several medications, leading to confusion and difficulty in following complex regimens. This complexity increases the likelihood of medication nonadherence. Lack of health literacy (A) may contribute but is not the primary factor. High cost of medications (B) and limited access to healthcare providers (C) are important barriers, but they are not as directly linked to nonadherence as the complexity of medication regimens.

Correct Answer: A

Rationale: Step 1: Acknowledge patient's concern. Step 2: Educate on normal aging changes affecting cognitive function. Step 3: Reassure patient that slight delays in tasks are common. Step 4: Encourage healthy habits to support cognitive function. Step 5: Emphasize the importance of monitoring any significant changes. Summary: Choice A is correct as it addresses the concern, educates on normal aging changes, reassures the patient, and provides guidance on monitoring. Choices B, C, and D are incorrect because they either suggest immediate evaluation without considering normal aging changes or provide inaccurate information about brain function in aging.

Correct Answer: A

Rationale: The correct answer is A: Cataracts. Cataracts are the most common type of vision impairment in older adults due to the clouding of the eye's lens. As people age, proteins in the lens can clump together, leading to vision issues. Glaucoma (B) is characterized by damage to the optic nerve, AMD (C) affects the macula in the retina, and diabetic retinopathy (D) is a complication of diabetes affecting blood vessels in the retina. However, cataracts are the primary cause of vision impairment in older adults due to the natural aging process of the eye.

Correct Answer: D

Rationale: The correct answer is D because reviewing a menu with the older man allows for personalized food selection, taking into account his preferences and dietary restrictions. This approach promotes adherence to a healthy eating plan, leading to better cholesterol management and overall wellness. Choice A is not the best option as simply instructing him to increase dietary fiber may not address his specific dietary needs. Choice B suggests asking the health care provider for a low-fat diet, which may not consider the individual's food preferences or cultural background. Choice C of scheduling a consultation with a dietitian is a good option, but it may not be as immediately accessible or practical as reviewing a menu together with the individual.

Correct Answer: B

Rationale: The correct answer is B: Stand on one foot at a time while supported. This exercise helps improve balance by challenging the proprioceptive system. By standing on one foot while supported, the older adult can gradually strengthen their muscles and improve their balance. Other choices like exercising with light weights may not specifically target balance, training with sit-ups focuses more on core strength, and working out in a swimming pool may provide buoyancy but may not directly address the balance concern.

Correct Answer: D

Rationale: The correct answer is D. Ingesting excessive acetaminophen can lead to liver damage, not renal failure. Diabetes mellitus, prostate hypertrophy causing urinary obstruction, and heart failure are known to cause renal failure due to their effects on kidney function. Diabetic nephropathy can damage the kidneys over time, prostate hypertrophy can obstruct urine flow and lead to kidney damage, and heart failure can result in decreased blood flow to the kidneys, causing renal failure. Thus, D is the correct answer as it does not directly cause renal failure, unlike the other choices.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Ageism is defined as prejudice or discrimination against individuals based on their age. 2. Choice A accurately defines ageism by highlighting the prejudicial nature and stereotyping of older adults. 3. Choices B and C are incorrect as ageism can occur against any age group, not just those over 65 or younger people in healthcare. 4. Choice D is incorrect as ageism involves negative stereotypes, not positive ones like assuming all older adults are wise.
