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: 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: D

Rationale: The correct answer is D: Infection. Older adults with diabetes are more vulnerable to infections due to weakened immune systems caused by high blood sugar levels. Infections can lead to severe complications and hospitalization. Stroke (A) is a common complication of diabetes but not the most common cause of hospitalization. Hypoglycemia (B) and diabetic ketoacidosis (C) are acute complications of diabetes but are less common causes of hospitalization compared to infections.

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: C

Rationale: The correct answer is C because gerontological nursing focuses on promoting health and maximizing independence in older adults. This statement aligns with the core principles of gerontological nursing, which emphasize holistic care and quality of life for elderly individuals. Choice A is incorrect because nurses have been involved in caring for older adults for a long time. Choice B is incorrect because gerontological care was not the second specialty certified by the ANA. Choice D is incorrect because ANA certification is not limited only to research positions in gerontological nursing.

Correct Answer: B

Rationale: Step 1: Maintaining cognitive function is crucial for adapting to changes and problem-solving in older age. Step 2: Social engagement helps combat loneliness and promotes mental well-being. Step 3: Both factors contribute to a higher quality of life and overall well-being in older individuals. Summary: A is incorrect as chronic diseases are common in aging. C is incorrect due to over-reliance on medical interventions. D is incorrect as independence doesn't necessarily equate to successful aging.

Correct Answer: C

Rationale: The correct answer is C: Pneumonia. Older adults are more susceptible to pneumonia due to weakened immune systems and underlying health conditions. Pneumonia can lead to severe complications, requiring hospitalization. Osteoarthritis (A) primarily affects joints and does not typically lead to hospitalization. Stroke (B) and heart failure (D) are serious conditions but may not be as common for hospitalization as pneumonia in older adults. Pneumonia's impact on the respiratory system and its ability to progress rapidly make it the most common reason for hospitalization in this population.

Correct Answer: A

Rationale: The correct answer is A: peripheral arterial disease. Altered level of consciousness in an 81-year-old female is unlikely to be directly caused by peripheral arterial disease. Instead, hypoglycemia, pneumonia, and hypotension from dehydration are common causes of altered mental status in the elderly. Hypoglycemia can lead to brain dysfunction, pneumonia can cause low oxygen levels affecting brain function, and dehydration-induced hypotension can reduce blood flow to the brain. Therefore, peripheral arterial disease is not typically a direct cause of altered consciousness in this scenario.

Correct Answer: B

Rationale: The correct answer is B because it directly addresses the older woman's emotional response to the instructions, showing empathy and understanding. By asking how she feels, the nurse can uncover any concerns or fears she may have, leading to effective communication and tailored support. Moving on to medication (A) ignores the woman's distress, potentially worsening the situation. Instructing the interpreter to repeat instructions (C) may not address the underlying issue. Having the woman repeat instructions (D) does not acknowledge her emotional state and may not resolve her tension.
