Cortisol And Thyroid Disorders Flashcards
What is the disease name for Hypercortisolism?
Cushing’s disease
What is the name of the disease for Hypocortisolism?
Addison’s disease
Individuals with hypercortisolism will manifest with a rise in plasma ___________ levels.
Glucose
Why do individuals with Cushing disease or syndrome develop a thinning of the dermis that leads to skin ulcerations?
Elevated cortisol promotes the breakdown of collagen in the dermis.
The most common cause of hypocortisolism is:
autoimmune destruction of adrenal cortex .
What are life threatening manifestations of severe hypocortisolism?
Hypoglycemia
Hypotension
A patient is diagnosed with secondary hyperthyroidism manifested by elevated T3/T4 and elevated TSH. What is a possible cause of this condition?
Pituitary gland adenoma
A pituitary gland tumor can over secrete TSH which leads to secondary hyperthyroidism.
What correctly describes the pathophysiology of Graves disease?
Production of antibodies that mimic TSH function
Which metabolic change is indicative of hyperthyroidism?
Weight loss
Increased T3/T4 levels causes a corresponding increase in the body’s metabolic rate, which leads to symptoms such as weight loss.
Which clinical consequences are associated with long term, untreated hypothyroidism?
weight gain.
diminished reflexes.
myxedema.
Which problem is a consequence of Hashimoto’s disease?
Hypothyroidism
Hashimoto’s disease or thyroiditis is caused by the production of antibodies that block TSH activity. This results in hypothyroidism.
A 46-year old woman is hospitalized following surgery to remove her thyroid gland (i.e., a thyroidectomy) due to thyroid cancer. Which assessment finding would the nurse be monitoring for immediately following the surgery?
Hypotension
A thyroidectomy is a surgery that results in the removal of the thyroid gland. Without a thyroid, the body cannot produce thyroid hormone (T3/T4). This puts the post-operative patient in a state of hypothyroidism until supplemental thyroid hormone (e.g. levothyroxine) can be started. Normally, thyroid hormone stimulates the sympathetic nervous system to raise blood pressure. Without thyroid hormone, the patient can become become dangerously hypotensive.
A patient is admitted to a medical surgical unit with a diagnosis of Addisonian crisis (i.e., severe Addison’s disease). Which findings should the interprofessional healthcare team focus on?
Hypoglycemia
Hypotension
The nurse is preparing a client with a new diagnosis of Graves disease for discharge. the nurse determines that the client understands the discharge instructions if the client states that which signs and symptoms are associated with this diagnosis?
Insomnia
Rapid heart rate and palpitations
Tremors
What are the clinical consequences of Hypercortisolism?
Hyperglycemia
Collagen breakdown in skin and blood vessels
Hypertension
Immunosuppression
