Maryville patho exam 1 question and answer study guide NURS 611 | Detailed Correct Solutions Which mineral is needed for thyroid-stimulating hormone (TSH) to stimulate the secretion of thyroid hormone (TH)? - answer - Iodide. What are clinical manifestations of hypothyroidism? - answer - decreased energy metabolism, resulting in constipation, bradycardia, and lethargy Thyroid-stimulating hormone (TSH) is released to stimulate thyroid hormone (TH) and is inhibited when plasma levels of TH are adequate. This is an example of: - answer - Negative feedback. Lipid-soluble hormone receptors are located: - answer - Inside the plasma membrane in the cytoplasm. The releasing hormones that are made in the hypothalamus travel to the anterior pituitary via the: - answer - Portal hypophyseal blood vessels. What effect does hyperphosphatemia have on other electrolytes? - answer - Decreases serum calcium. . Insulin transports which electrolyte in the cell? - answer - Potassium. Which second messenger is stimulated by epinephrine binding to a β-adrenergic receptor? - answer - Cyclic adenosine monophosphate (cAMP). These molecules are the initial link between the first signal (hormone) and the inside of the cell. For example, the binding of epinephrine to a β adrenergic-receptor subtype activates (through a stimulatory G protein) the enzyme, adenylyl cyclase. Adenylyl cyclase catalyzes the conversion of adenosine triphosphate (ATP) to the second messenger, 3', and Regulation of the release of catecholamines from the adrenal medulla is an example of which type of regulation? - answer - Neural. Which hormone does the second messenger calcium (Ca++) bind to activate phospholipase C through a G protein? - answer - Angiotensin II. this bodily element is considered an important second messenger that facilitates the binding of a hormone (e.g., norepinephrine, angiotensin II) to a surface receptor, activating the enzyme phospholipase C through a G protein inside the plasma membrane. The control of calcium in cells is important because it: - answer - Acts as a second messenger Where is antidiuretic hormone (ADH) synthesized, and where does it act? - answer - Hypothalamus; renal tubular cells. How does a faulty negative-feedback mechanism result in a hormonal imbalance? - answer - Excessive hormone production results from a failure to turn off the system. A deficiency of which chemical may result in hypothyroidism? - answer - iodine. What imbalance lessens the rate of secretion of parathyroid hormone - answer - Increased serum calcium levels. Which condition may result from pressure exerted by a pituitary tumor? - answer - Hypothyroidism. Which substance is a water-soluble protein hormone? - answer - Insulin. Which of the following is a lipid-soluble hormone? - answer - Cortisol. When insulin binds its receptors on muscle cells, an increase in glucose uptake by the muscle cells is the result. This is an example of what type of effect by a hormone? - answer - Direct. Graves disease develops from a(n): - answer - Viral infection of the thyroid gland that causes overproduction of thyroid hormone. Autoimmune process during which lymphocytes and fibrous tissue replace thyroid tissue. Pathologic changes associated with Graves disease include: - answer - High levels of circulating thyroid-stimulating immunoglobulins. The signs of thyrotoxic crisis include: - answer - Hyperthermia and tachycardia The level of thyroid-stimulating hormone (TSH) in individuals with Graves disease is usually: - answer - Low. Palpation of the neck of a person diagnosed with Graves disease would detect a thyroid that is: - answer - Diffusely enlarged. The effects of the syndrome of inappropriate antidiuretic hormone (SIADH) secretion include solute: - answer - Retention and water loss The common cause of elevated levels of antidiuretic hormone (ADH) secretion is: - answer - Ectopically produced ADH Which la
