Q

A 90-year-old patient presents with a recent history of falls and unsteady gait. On examination, you notice a broad-based ataxic gait. What are the potential causes of gait disturbances in the elderly?

A

Potential Causes of Gait Disturbances in the Elderly:

  • Cerebellar Dysfunction: Dysfunction of the cerebellum can lead to ataxic gait. Causes may include cerebellar strokes, tumors, or degenerative conditions like cerebellar ataxia.
  • Peripheral Neuropathy: Peripheral neuropathy, often related to diabetes or other metabolic conditions, can result in sensory deficits and affect gait.
  • Vestibular Disorders: Disorders of the vestibular system in the inner ear can cause balance problems and unsteady gait.
  • Musculoskeletal Issues: Arthritis, joint problems, and musculoskeletal conditions can impact gait stability.
  • Medications: Certain medications, such as sedatives, antiepileptics, and psychotropic drugs, may contribute to gait disturbances, especially in the elderly.
  • Normal Aging: Age-related changes in musculoskeletal and sensory systems can lead to gait changes in older adults.
41
Q

Mrs. Johnson, an 80-year-old female, presents with progressive difficulty walking and occasional falls. She has a history of osteoarthritis and hypertension. On examination, you notice muscle weakness and decreased deep tendon reflexes in her lower extremities. What is the most likely diagnosis?

What orders will you order to diagnose?

A

Spinal Stenosis

*Her age, history of osteoarthritis puts them at a higher risk

MRI is gold standard

42
Q

Although helpful in younger patients to treat insomnia, what medications should be avoided in the elderly with insomnia?

What should be used instead?

A

Benzodiazepines and Benzodiazepine receptor agonists (NBRAs)

Ramelton (Melatonin receptor agonist)

43
Q

What is the most common malnutrition deficiency in older adults?

A

Protein deficiency

44
Q

Mrs. Johnson, an 80-year-old woman, presents with acute confusion, fever, and lower abdominal pain. On examination, you note suprapubic tenderness. What is the most likely diagnosis?

A) Urinary tract infection (UTI)
B) Dementia exacerbation
C) Gastroenteritis
D) Osteoarthritis

A

Urinary Tract Infection (UTI)

45
Q

Which of the following medications should be used with caution in older adults due to the risk of anticholinergic side effects?

A) Acetaminophen
B) Lorazepam
C) Lisinopril
D) Metformin

A

Lorazepam

Lorazepam is a benzodiazepine that will increase the risk of anticholinergic side effects. Anticholinergic side effects can include confusion, memory impairment, and an increased risk of falls.

46
Q

Which screening tool is commonly used to assess cognitive impairment in older adults and is sensitive to detecting Alzheimer’s disease?
A) Mini-Mental State Examination (MMSE)
B) Geriatric Depression Scale (GDS)
C) Katz Index of Independence in Activities of Daily Living (ADL)
D) Timed Up and Go (TUG) Test

A

Mini-Mental State Exam (MMSE)

47
Q

What is the primary risk factor for developing pressure ulcers in older adults residing in long-term care facilities?

A) Malnutrition
B) Smoking
C) Frequent position changes
D) Adequate hydration

A

Malnutrition

48
Q

Can physical therapy and relaxation techniques be helpful in reducing delirium risk in hospitalized older adults?

A

Yes, uncontrolled pain can lead to delirium. PT or relaxation techniques are a few non-pharmacological pain managament strategies in preventing delirium.

Early mobilization should be encouraged!
