16
Q

diagnostic studies for addisons disease

A

-ACTH stimulation test

17
Q

ACTH stimulation test

A

*Baseline cortisol and ACTH levels are measured, and the patient is given an IV injection of synthetic ACTH (cosyntropin).
*Cortisol and ACTH levels are rechecked after 30 and 60 minutes. TIMING

18
Q

normal vs addisons disease reaction to ACTH stimulation test

A

normal: rise in blood cortisol levels
-addisons: little or no increase in cortisol

19
Q

when the response to the ACTH test is abnormal, what is done

A

CRH stimulation test

20
Q

CRH stimulation test

A

The patient is given an IV injection of synthetic CRH, and blood is taken after 30 and 60 minutes.

21
Q

lab findings for addisons

A

-↑ Potassium
-↓ Chloride, sodium, glucose
-Anemia
-↑ BUN
-ECG changes (*peaked T waves caused by hyperkalemia.)

22
Q

interprofessional care for addisons

A

-hormone therapy (hydrocortisone)
-Fludrocortisone (Florinef)
-INCREASE DURING PERIODS OF STRESS
-increase dietary salt intake

23
Q

HINT HINT: Fludrocortisone (Florinef)

A

mineralcorticoid replacement for addisons, pt will be on lifelong hormone therapy

24
Q

interprofessional care for addisonian crisis

A

-Shock management
-High-dose hydrocortisone replacement
-0.9% saline solution and 5% dextrose (to revers hypotension and electrolyte imbalance until BP returns)

25
Q

acute care

A

-Correct fluid and electrolyte imbalance
-Assess vital signs and neurologic status
-Daily weight
-Accurate I and O
-Obtain complete medication history
-Watch for signs of Cushing syndrome

26
Q

watch for manifestations of cushings

A

blood pressure, weight gain, weakness, or other manifestations

27
Q

HINT HINT: patient teaching for dosing: glucocorticoids

A

divided doses: one on morning, once at night

28
Q

HINT HINT: patient teaching for dosing: mineralcorticoids

A

once in the morning (to match circadiam rhythm)

29
Q

corticosteroids and stress

A

NEED TO INCREASE DURING TIMES OF STRESS

30
Q

patient teaching

A

-Report signs and symptoms of corticosteroid deficiency and excess to HCP
-Carry identification and wear medical ID bracelet
-Emergency kit
-How to administer IM hydrocortisone
-Written instructions

31
Q

side effects with corticosteroid therapy

A

-↓ Potassium and calcium
-↑ Glucose and BP
-Delayed healing
-Susceptibility to infection
-Suppressed immune response
-PEPTIC ULCER DISEASE
-Muscle atrophy/weakness
-Mood and behavior changes
-Moon facies, truncal obesity
-Protein depletion
-Risk for acute adrenal crisis if therapy is stopped abruptly

32
Q

Expected effects of corticosteroid therapy

A

-Antiinflammatory action
-Immunosuppression
-Maintenance of normal BP

33
Q

corticosteroid therapy: dietary needs

A

*diet high in protein, calcium (at least 1500 mg/day), and potassium but low in fat and concentrated simple carbohydrates such as sugar, honey, syrups, and candy.

34
Q

corticosteroid therapy: Rest and exercise needs

A

*Identify measures to ensure adequate rest and sleep, such as daily naps and avoidance of caffeine late in the day.
*Develop and maintain an exercise program to help maintain bone integrity.

35
Q

corticosteroid therapy: Sodium restriction if edema occurs

A

*Recognize edema and ways to restrict sodium intake to less than 2000 mg/day if edema occurs.

36
Q

corticosteroid therapy: hyperglycemia

A

Monitor glucose levels and recognize symptoms of hyperglycemia (e.g., polydipsia, polyuria, blurred vision).

37
Q

corticosteroid therapy patient teaching

A

-Should be taken in morning with food to reduce gastric irritation and reduce ulcers
-Must NOT be stopped abruptly
-Needs to INCREASE in times of stress
