Hyperparathyroidism

The PATHO of this disease ends in hypercalcemia?

Hyperparathyroidism

This disease causes excess secretion of PTH and increases reabsorption of Calcium by the kidneys

Hyperparathyroidism

Hyperthyroidism

This disease can cause nervousness, weight loss, hyperactive reflexes, diaphoresis, and expothalmous..?

Hyperthyroidism

A nurse is caring for a client that had a thyroidectomy. What should the nurse assess for after surgery?

Hypocalcemia

Insufficient PTH, causing decrease in calcium levels ending in hypocalcemia

Hypoparathyroidism

This disease causes a slow basal metabolic rate

Inadequate ADH secretion

What is secreted by the beta cells of islets of Langerhans?

Insulin

Hypothyroidism is?

Low production of T3 and T4 hormones to cause an increased production of TSH

Thyroxine stimulates?

Metabolic rate
