Q

Functional Status

A

Difficulty, degree of dependence and change in ability in both self-care or basic ADLs and instrumental ADLs.
These are important to ascertain as a change or decline in one’s functional status may indicate the onset of a new illness or worsening of an existing illness.

Q

Myocardial Ischemia

A

The classic anterior chest pain of angina pectoris is frequently absent

Symptoms and Signs:
19-66% = chest pain
20-59% = dyspnea
15-33% = neurological symptoms (falling, vertigo)
0-19% = GI symptoms (n/v, heartburn, epigastric distress)
Other symptoms/signs = palpitations, increased claudication, PE, restlessness, sweating, sudden cardiac death, confusion, syncope or near syncope.

17

18
Q

Peptic Ulcer Disease

A

excoriated segment of the GI mucosa, typically in the stomach (gastric) or first few centimeters of the duodenum (duodenal).

19
Q

PUD - atypical

A

fewer and less severe symptoms typical of PUD due to a decrease in sensation of visceral pain.
- Abdominal pain may be absent or of minimal severity even in those older patients who require hospitalization
Abdominal discomfort is absent in 50%. If abdominal pain is present, it is often nondescript, poorly localized, not necessarily “burning”, often not relieved by eating and may have misleading patterns of radiation.
- Melena (stool darkened by oxidized blood) is the most common clinical presentation of duodenal ulcer.
- 2MC: dyspepsia and tenderness on abdominal exam.

Also: Confusion, Abdominal distention, Anorexia and weight loss

Complications occur in approximately 50%
bleeding (mortality rate of elderly with bleeding ulcer = 29-60%)
Perforation
Gastric outlet obstruction (due to inflammation/edema/scarring)
penetration

20
Q

Constipation

A

Constipation is the most common GI complaint in the elderly, with up to 60% of outpatients reporting use of laxatives.

Symptoms: abdominal discomfort, loss of appetite and nausea

21
Q

Fecal Impaction

A

low fiber diets
low fluid intake
decreased motor activity of smooth muscles of the bowel
decreased sensory function of the rectum/anus
Medications
Decreased physical activity and ambulation

It can be life threatening.
Intestinal obstruction
Colonic ulceration
Overflow incontinence
Paradoxical diarrhea
Urinary retention/infections
Straining: hemorrhoids, syncope, TIAs, cardiac ischemia, anal fissures, rectal prolapse
22
Q

Fecal Impaction Typical Sxs

A

anorexia
nausea and vomiting
Paradoxical diarrhea/incontinence of stool
Abdominal pain may be present or absent
Urinary retention, frequency and overflow incontinence

23
Q

Hypothyroidism

A

more common in the elderly
TSH rises without a change in serum T4
most frequently due to autoimmune thyroiditis (Hashimoto’s).

24
Q

Common Causes of Hypothyroidism

A
Most common:
Hashimoto’s thyroiditis
Previous irradiation
Surgical removal of thyroid gland

Use of lithium or other antithyroid drugs

25
Q

27
Q

Screening Hypothyroidism in elderly

A

TSH
Screening every 5 years for all men 65 and older
Screening every 5 years for all women 35 and older
More frequent screenings should be performed for those with risk factors for thyroid disease

28
Q

Hyperthyroidism in elderly

A
Most common cause in younger adults: Grave’s disease
Most common cause(s) in elderly:
Multinodular and uninodular toxic goiter

Proximal Muscle Weakness
Insomnia
Adrenergic symptoms
Palpitations
Tremor
Frequent Bowel Movements, Diarrhea
Excessive Sweating
Heat intolerance
Miscellaneous
Weight loss despite increased appetite (hypermetabolism)
Oligomenorrhea or Amenorrhea
30
Q

Classic Tried for Hyperthyroid

A

Young: tachycardia, exopthalamous, goiter
Elderly: tachy, weight loss, fatigue (weakness/apathy)

31
Q

Apathetic Hyperthyroidism

A

Many of the common symptoms of hyperthyroidism in the elderly are similar to those generally associated with hypothyroidism such as depression, lethargy, congestive heart failure, constipation and muscle weakness.
Thyrotoxicosis is uncommon in the elderly.

32
Q

Hyperthyroidism Atypical S/Sxs

A

Ocular signs
Decreased appetite
Tachycardia in the elderly is defined as how many beats per minute?
Thyroid gland size = enlarged, normal size or impalpable?
Diarrhea or constipation = which is more common?
Nervousness/anxiety = more or less common than in younger patients?
Sweating = more or less common than in younger patients?
Observed tremor = more or less common than in younger patients?
Hyperactive reflexes with quick recoil = more or less common than in younger patients?

May present with cardiac signs/symptoms of heart failure and angina.
Because cardiac issues are very prevalent in the elderly population, the possibility of an underlying hyperthyroidism is likely to be missed or not even suspected.

33
Q

Hyperparathyoidism

A

produce excessive PTH resulting in disorders of bone metabolism.
The incidence of primary hyper-parathyroidism increases steadily with age

34
Q

clinical state characterized by an acute, fluctuating change in mental status, with inattention and altered levels of consciousness.
may develop over a short period of time and may fluctuate daily.

*does NOT present differently in the elderly patient compared to the young adult patient. Causes of acute confusion or delirium in the elderly are more varied and encompass a larger range of disorders including metabolic, neurologic and medication toxicity.
