Chapter 47: Assessment of Endocrine system
The parathyroid glands are
four small, oval structures usually arranged in pairs behind each thyroid lobe. they secrete parathyroid hormone (PTH)
insulin is
An anabolic hormone secreted by the pancreas it is the principal regulator of the metabolism and storage of ingested carbohydrates, fats, and proteins.
Calcitonin is a hormone made by
C cells of the thyroid gland in response to high circulating calcium levels
Which skin condition would the nurse expect to assess in a patient diagnosed with Addison's disease?
Darkened skin on the knuckles, elbows, and palmar creases
which hormone declines in menopause and results in an increased risk for arteriosclerosis and osteoporosis?
Estrogen
Which instructions would the nurse tell a patient who is having an ultrasound of the thyroid gland?
Inform the patient that a gel and transducer will be used over the neck. the test will last 15 minutes
what is required for the synthesis of thyroid hormones?
Iodine
glucagon is
a catabolic hormone, increases blood glucose by stimulating glycogenolysis, gluconeogenesis, and ketogenesis
Which hormone level would the nurse expect to be elevated in response to a low serum cortisol level?
adrenocorticotropic hormone (ACTH) a negative feedback mechanism controls cortisol secretion. The release of corticotropin-releasing hormone from the hypothalamus stimulates the secretion of ACTH by the anterior pituitary. ACTH stimualtes the adrenal cortex to secrete corticosteroids
Which hormone is essential for the maintenance of fluid and electrolyte balance?
aldosterone
Which hormone level requires a patient to maintain a supine position for two hours before a prescribed blood sample is collected?
aldosterone before assesswing aldosterone hormone levels, the nurse should instruct the patient to lie in a supine position for at least two hours before obtaining the blood sample. This ensures the assessment of accurate levels of aldosterone.
which hormone may be altered if a patient has dehydration and polyuria?
antidiuretic hormone (ADH) ADH decreases urine production by causing the renal tubules to reabsorb water from the urine and return it to the circulating blood. Polyuria is excessive urination, which might indicate an alteration in this hormone.

calcium levels the parathyroid gland plays a key role in maintaining calcium levels.
Which diet would the nurse suggest to a patient with low levels of parathormone in the blood and who is experiencing frequent muscle spasms in the extremities?
calcium-rich diet Hypoparathyroidism, or low levels of parathormone, may lead to tetany in the patient. Tetany manifests as muscle spasms in the extremities at irregular intervals. Tetany may occur due to low levels of calcium. Parathormone reguluates calcium levels in the blood.

All cells in the body are believed to have intracellular receptors for
thyroid hormone there are two types of receptors: those that are within the cell (steroid, thyroid hormone receptors) and those that are on the cell membrane (water-soluble hormone receptors). Thyroid hormone receptors are found inside the cell. because these hormones are lipid soluble, they pass through the target cell membrane by passive diffusion and bind to receptor sites found in the cytoplasm or nucleus of the target cell

which statement correctly illustrates the concept of the negative feedback system for control of serum cortisol?
A decreased secretion of ACTH when serum cortisol is increased. the releationship between cortisol and ACTH relies on negative feedback. The increased blood cortisol level suppresses ACTH release. Low blood levels of cortisol stimulate the pituitary gland to release ACTH, which acts on the adrenals to secrete cortisol and thereby increase blood cortisol levels.

A characteristic common to all hormones is that they
influence cellular activity of specific target tissues A hormone is a chemical substance synthesized and secreted by a specific organ or tissue. Most hormones have common characteristics, including (1) secretion in small amounts at variable but predictable rates, (2) circulation through the blood, and (3) binding to specific cell receptors in the cell membrane or within the cell.

melanocyte-stimulating hormone (MSH)
Which hormone will be decreased if there is damage to the pineal gland?
melatonin the pineal gland, located in the brain, secretes the hormone melatonin. Damage to this gland leads to altered regulation of melatonin in the patient
T3 and T4 affect what?
metabolic rate carbohydrate lipid metabolism growth and development nervous system activities
which hormone increases bone demineralization?
parathyroid hormone The parathyroid gland secretes parathyroid hormone (PTH) ,which regulates the blood level of calcium. PTH stimulates the transfer of calcium from the bone into the blood. Parathyroid hormone stimulates the renal conversion of vitamin D to its most active form, 1, 25-dihydroxyvitamin D 3. This active form of vitamin D promotes absorption of calcium and phosphorous by the gastrointestinal tract, which ultimately increases bone demineralization.
which gland would a nurse suspect may be causing disturbances in a teenage female patient's menstrual cycle?

A patient has a serum sodium level of 152 mEq/L (152 mmol/L). The normal hormonal response to this situation is
release ADH the most important stimulus of antidiuretic hormone (ADH) secretion is plasma osmolality, which is a measure of solute concentration in circulating blood. Plasma osmolality increases when there is a decrease in extracellular fluid or an increase in solute concentration. The increased plasma osmolality activates osmoreceptors, which are extremly sensitve, specialized neurons in the hypothalamus. These activated osmoreceptors stimulate ADH release. When ADH is release, the renal tubules reabsorb water, which causes urine to be more concentrated.
Which test would the nurse prioritize for a patient with hypoparathyroidism who presents with intermittent, involuntary muscle spasms of the legs and arms?
