endocrine nursing assessment
Differentiate normal from common abnormal findings of a physical assessment of the endocrine system. Pain, emotion, sexual excitement, and stress can stimulate the nervous system to modulate hormone secretion. NURSING 1ST YEAR ENDOCRINE SYSTEM 2. In this situation, the first hormone in the series may have another endocrine gland as its target tissue. Corticosteroids (e.g., cortisol, hydrocortisone) Hormone-receptor actions work in a “lock and key” manner in that only the correct hormone (key) can bind to and activate the receptor site (lock) (Fig. Increased nodules. Negative feedback is similar to the functioning of a thermostat in which cold air in a room activates the thermostat to release heat, and hot air signals the thermostat to prevent more warm air from entering the room. These activated osmoreceptors stimulate ADH release. *In men, sometimes referred to as interstitial cell–stimulating hormone (ICSH). The pituitary gland is located at the base of the brain in a protective pocket of the sphenoid bone (see Fig. Decreased β-adrenergic receptor response to norepinephrine. Adrenal secretion of these hormones is usually not significant because the gonads (testes and ovaries) secrete much larger amounts of androgens and estrogens. For example, catecholamines are hormones when they are secreted by the adrenal medulla, but act as neurotransmitters when secreted by nerve cells in the brain and peripheral nervous system. Stimulates milk secretion, uterine contractility. GLANDS: An organ which secretes particular chemical substances for use in the body or for discharge into the surroundings. The islets account for less than 2% of the gland and consist of four types of hormone-secreting cells: α, β, delta, and F cells. Hypothalamus An example of the bodys response to the endocrine system includes all of the following except: 1. Hormone secretion usually depends on the need of the body for the final action of that hormone. Endocrine disorders: Assessment. Decreased plasma levels of adrenal androgens and aldosterone. The most common adrenal androgens are dehydroepiandrosterone (DHEA) and androstenedione. High circulating thyroid hormone levels inhibit the secretion of both TRH from the hypothalamus and TSH from the anterior pituitary gland. The adrenal medullary hormones are not essential for life because they also are secreted by other body tissues, but they do play a role in the physiologic stress response. However, triiodothyronine (T3) is much more potent and has greater metabolic effects. Hormones act only on cells that have receptors specific to that hormone, since the shape of the receptor determines which hormone can react with it. It consists of two encapsulated lateral lobes connected by a narrow isthmus (Fig. Describe the functions of hormones secreted by the pituitary, thyroid, parathyroid, and adrenal glands and the pancreas. Aldosterone synthesis and secretion are stimulated by angiotensin II, hyponatremia, and hyperkalemia. glucagon, p. 1140 In the fasting state, hormones such as catecholamines, cortisol, and glucagon break down stored complex fuels (catabolism) to provide glucose as fuel for energy. The islets account for less than 2% of the gland and consist of four types of hormone-secreting cells: α, β, delta, and F cells. HORMONES OF THE HYPOTHALAMUS The structural detail of the adrenal gland. This local effect is called. Glucagon and insulin function in a reciprocal manner to maintain normal blood glucose levels. Stimulates milk secretion, uterine contractility. Hormone A fits and binds to its receptors, causing a change in cell action. Thyroid Hormones 48-5). In the previous NCLEX review series, I explained thyroid gland disorders, such as hypothyroidism and hyperthyroidism and how they affect the body along with nursing interventions. Simple Feedback. Its release is triggered by a decrease in extracellular fluid volume from blood loss, sodium loss, or posture changes. Cortisol decreases the inflammatory response by stabilizing the membranes of cellular lysosomes and preventing increased capillary permeability. Endocrine System Q&A Nursing Care. Stimulates development of secondary sex characteristics, spermatogenesis. 48-6 Relationship between the hypothalamus, pituitary, and target organs. Estrogen α Cells produce and secrete the hormone glucagon. PTH acts on bone, the kidneys, and indirectly on the GI tract. Adrenal Medulla 64-3 Examples of positive and negative feedback control of hormone secretion. Exocrine glands are not part of the endocrine system. catecholamines, p. 1140 48-8). The thyroid gland is a highly vascular organ, and its size is regulated by TSH from the anterior pituitary. ADH is also a potent vasoconstrictor. Select the significant subjective and objective assessment data related to the endocrine system that should be obtained from a patient. The homeostatic mechanism is considered negative feedback because it reverses the change in blood glucose level. In addition, high levels of active vitamin D inhibit PTH, and low levels of magnesium stimulate PTH secretion. Many are produced in one part of the body and control and regulate the activity of certain cells or organs in another part of the body. 7. 64-1). These include (1) decreased hormone production and secretion, (2) altered hormone metabolism and biologic activity, (3) decreased responsiveness of target tissues to hormones, and (4) alterations in circadian rhythms. The hormones secreted by the cortex are often called adrenal steroids or corticosteroids. Stimulates secretion of corticosteroids. For example, salivary glands produce saliva, which is secreted through salivary ducts into the mouth. The secretion of PTH is directly regulated by a feedback system. The term corticosteroid refers to hormones synthesized by the adrenal cortex excluding androgens. Hormone levels fluctuate predictably during these cycles. After a meal, insulin is responsible for the storage of nutrients (anabolism). The pituitary gland is about 1 cm in diameter and is divided into the anterior lobe. ACTH, Adrenocorticotropic hormone; CRH, corticotropic hormone. Pituitary FIG. Download chart. Water-soluble hormones are not dependent on plasma proteins for transport (see Fig. Men: Decline in testosterone secretion. Glands Increased calcium resorption from bone. It promotes sodium and water reabsorption and potassium excretion in the kidney tubules. The hypothalamus shares a small, closed circulatory system with the anterior pituitary gland, known as the, The pituitary gland is located at the base of the brain in a protective pocket of the sphenoid bone (see Fig. Endocrine System 2.

FIG. Stimulates glycogenolysis and gluconeogenesis. Neurons from the hypothalamus create a circuit to facilitate coordination of the endocrine system and autonomic nervous system (ANS). Nursing management of the patient with diabetes who is admitted to hospital 320. Melatonin secretion is increased in response to exposure to the dark and decreased in response to light. Table 64-1 lists hormones secreted by various endocrine glands. FIG. Which is why I was so surprised when I realized that I’ve never, ever explained the best way to study Endocrine diseases on this blog. 48-5). Renin converts renin substrate (formerly called, Carbohydrate, protein, and fat metabolism, Prevent hypoglycemia by increasing liver gluconeogenesis and inhibiting peripheral glucose use, Maintain excitability and responsiveness of cardiac muscle, Increase lipolysis, releasing glycerol and free fatty acids, Increase the number of mature neutrophils released from bone marrow, Exert anti-inflammatory effects that decrease the migration of inflammatory cells to sites of injury, Maintain behavior and cognitive functions, Glucocorticoid release is regulated directly by the anterior pituitary hormone, As described earlier and shown in Fig. Glucocorticoid release peaks in the morning and reaches its lowest level 12 hours after each peak. The problem-focused endocrine assessment is necessary after a comprehensive assessment indicates a potential endocrine abnormality, or when a new symptom emerges or the patient develops any distress. Describe the functions of hormones secreted by the pituitary, thyroid, parathyroid, and adrenal glands and the pancreas. When blood glucose levels start to rise above normal, the hormone insulin is secreted. * These hormones are synthesized in the hypothalamus and are stored in the posterior pituitary gland. The other system is the nervous system. Melanocytes in skin TABLE 64-3 FUNCTIONS OF GLUCOCORTICOID HORMONES, • Prevent hypoglycemia by increasing liver gluconeogenesis and inhibiting peripheral glucose use, • Maintain excitability and responsiveness of cardiac muscle, • Increase lipolysis, releasing glycerol and free fatty acids, • Increase the number of mature neutrophils released from bone marrow, • Exert anti-inflammatory effects that decrease the migration of inflammatory cells to sites of injury, • Maintain behavior and cognitive functions. The main glucocorticoid produced by the adrenal cortex is cortisol. Effects of Aging on Endocrine System Hormone secretion usually depends on the need of the body for the final action of that hormone. The pattern of insulin secretion is a physiologic example of negative feedback between glucose and insulin. Each gland consists of two parts, the medulla and the cortex (Fig. Cortisol also helps maintain vascular integrity and fluid volume through its action on mineralocorticoid receptors. 9. The major physiologic role of ADH (also called arginine vasopressin) is regulation of fluid volume by stimulating reabsorption of water in the renal tubules. The function of the testes and ovaries is detailed in Chapter 72. Decreased metabolic clearance rate for glucocorticoids. As the correction occurs, hormone secretion decreases (and may halt). The parathyroid glands lie on the posterior surface of the thyroid gland. Somatostatin The differences in solubility become important in understanding how the hormone interacts with the target cell. Increased in response to stress. Two important groups of hormones from the hypothalamus are, Growth hormone–releasing hormone (GHRH), or somatotropin-releasing hormone, Somatostatin (inhibits growth hormone release), The anterior lobe accounts for 80% of the gland by weight and is regulated by the hypothalamus through releasing and inhibiting hormones. Increases melanin production in melanocytes to make skin darker. The posterior pituitary is composed of nerve tissue and is essentially an extension of the hypothalamus. The secretion of the hormone, The thyroid gland is located in the anterior portion of the neck in front of the trachea. The adrenal glands are vascular, tent-shaped organs on the top of each kidney that have an outer cortex and an inner medulla (see Fig. Select the significant subjective and objective assessment data related to the endocrine system that should be obtained from a patient. Amylin (from β cells) 4. This system allows hormones produced in the hypothalamus to travel directly to the anterior pituitary gland so that only very small amounts are wasted in systemic circulation. 3. In general, each receptor site type is specific for only one hormone. Stimulation of the sympathetic nervous system causes the release of adrenal medullary hormones, the, These receptors are of two types: alpha adrenergic and beta adrenergic. 64-5 The structural detail of the adrenal gland. The normal blood level range of each hormone is well defined. Women who have adrenal insufficiency or who have had surgical removal of the adrenals may need a small amount of testosterone replacement. Presentation and treatment of diabetes 318. 8. Adrenal Cortex. These glands then secrete hormones into the blood that then act on their target organs or tissues, resulting in a change of at least one function. Assess whether the patient has experienced recent changes in behavior or responses to stress. In men, sometimes referred to as interstitial cell–stimulating hormone (ICSH). Development of breast buds for a 10-year-old girl. The increased blood calcium level then inhibits further PTH release (Fig. These include (1) decreased hormone production and secretion, (2) altered hormone metabolism and biologic activity, (3) decreased responsiveness of target tissues to hormones, and (4) alterations in circadian rhythms. The hormones of the posterior pituitary, vasopressin (antidiuretic hormone [ADH]) and oxytocin, are produced in the hypothalamus and sent through the nerve tracts that connect the hypothalamus with the posterior pituitary. Function of these glands begins at puberty. 1. The locations of various glands within the endocrine system. Communication between the hypothalamus and posterior pituitary occurs through nerve tracts known as the median eminence. It also has numerous biologic actions, including a role in protein, fat, and carbohydrate metabolism. Normal aging has many effects on the endocrine system (Table 48-3). Increases response of follicles to LH and FSH. When epinephrine, a catecholamine, travels through the blood, it is a hormone and affects target tissues. Negative feedback is similar to the functioning of a thermostat in which cold air in a room activates the thermostat to release heat, and hot air signals the thermostat to prevent more warm air from entering the room. Aldosterone is a potent mineralocorticoid that maintains extracellular fluid volume. A smaller intermediate lobe produces melanocyte-stimulating hormone. Elevated blood glucose levels stimulate the secretion of insulin from the pancreas (see eFig. The hypothalamus also contains neurons, which receive input from the CNS, including the brainstem, limbic system, and cerebral cortex. The purpose of all endocrine glands is to secrete. • In the pituitary gland, the releasing or inhibiting factors either stimulate or inhibit the release of specific hormones. The parathyroid gland is located in the neck on the […] Select the significant subjective and objective assessment data related to the endocrine system that should be obtained from a patient. Prolactin stimulates breast development necessary for lactation after childbirth. The adrenal medulla is the inner part of the gland and consists of sympathetic postganglionic neurons. Describe the locations and roles of hormone receptors. Increased glucose intolerance and decreased sensitivity to insulin. Glucocorticoids inhibit the inflammatory response and are considered antiinflammatory. Several hormones secreted by the anterior pituitary are referred to as tropic hormones. The anterior and posterior pituitary hormones are shown with their target tissues. Aldosterone is the major mineralocorticoid and maintains extracellular fluid volume. An example of a simple negative feedback hormone response is the control of insulin secretion. Influences regulation of pancreatic exocrine function and metabolism of absorbed nutrients. Endocrinology is an amazing discipline, offering a compromise between chronic disease management and acute medical interventions; taking the best aspects of working in A & E, whilst still offering time on the ward and focusing on the person behind the patient chart. However, the brain, nerves, lens of the eye, hepatocytes, erythrocytes, and cells in the intestinal mucosa and kidney tubules are not dependent on insulin for glucose uptake. When ADH is released, the renal tubules reabsorb water and the urine becomes more concentrated. TABLE 64-2 PITUITARY HORMONES: TARGET TISSUES AND SUBSEQUENT ACTIONS. 48-7). The secretion of PTH is directly regulated by a feedback system. Promotes movement of glucose out of blood and into cells. 7. Oxytocin stimulates ejection of milk into mammary ducts during lactation and contraction of the uterus; it may also affect sperm motility. The pituitary gland (hypophysis) is located in the sella turcica under the hypothalamus at the base of the brain above the sphenoid bone (see Fig. In addition, the hypothalamus coordinates the expression of complex behavioral responses, such as anger, fear, and pleasure. Liver, stomach The hormones secreted by the posterior pituitary, antidiuretic hormone (ADH) and oxytocin, are actually produced in the hypothalamus. Identify the locations of the endocrine glands. Pain, emotion, sexual excitement, and stress can stimulate the nervous system to modulate hormone secretion. A common physiologic rhythm is the circadian rhythm. Although lipid-soluble hormones are inactive when bound to plasma proteins, they can be released when appropriate and immediately exert their action at the target tissue. Hormones are classified by their chemical structure as either lipid soluble or water soluble. Follicle-stimulating hormone (FSH) stimulates secretion of estrogen and the development of ova in women and sperm in men. It secretes several steroid hormones, including, One major function of cortisol is the regulation of blood glucose concentration through stimulation of hepatic glucose formation. The following hormones from the hypothalamus target the anterior pituitary. The adrenal medulla is a sympathetic nerve ganglion that has secretory cells. Calcitonin inhibits the transfer of calcium from bone to blood, increases calcium storage in bone, and increases renal excretion of calcium and phosphorus, thereby lowering serum calcium levels. Then ACTH triggers the adrenal cortex to secrete cortisol. • Prolactin-inhibiting factor (PIF) Chapter 48 In response, normal blood cortisol levels are maintained. Increases in response to stress. FIG. 4. Excesses or deficiencies of hormone secretion can lead to pathologic conditions. 48-6). In addition, PTH stimulates the renal conversion of vitamin D to its most active form (1,25-dihydroxyvitamin D3). Assess whether the patient has experienced recent changes in behavior or responses to stress. It consists of two encapsulated lateral lobes connected by a narrow isthmus (Fig. Thyroid hormone production and release is stimulated by TSH from the anterior pituitary gland. This sympathetic activation results in the “fight-or-flight” response, a state of heightened physical and emotional awareness. Decreased metabolism of cortisol. Luteinizing hormone (LH) stimulates ovulation in women and secretion of sex hormones in both men and women. 48-2). 2. The hypothalamus is a small area of nerve and glandular tissue located beneath the thalamus in the brain. It is the most common type of endocrine feedback system and results in the gland increasing or decreasing the release of a hormone. Other actions keep the serum sodium level between 136 and 145 mEq/L (mmol/L), regardless of whether a person eats 2 g or 12 g of sodium per day. Releasing Hormones Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. 64-4 The hypothalamus, hypophysial stalk, anterior pituitary gland, and posterior pituitary gland. Glucocorticoids (e.g., cortisol) are named for their effects on glucose metabolism. 2. Study Nursing Assessment of the Endocrine System (Test 2) flashcards from Morgan LeBrun's class online, or in Brainscape's iPhone or Android app. A smaller intermediate lobe produces melanocyte-stimulating hormone. When the serum calcium level is low, PTH secretion increases. Aldosterone is a potent mineralocorticoid that maintains extracellular fluid volume. In addition, the hypothalamus coordinates the expression of complex behavioral responses, such as anger, fear, and pleasure. This active vitamin D promotes absorption of calcium and phosphorus by the GI tract, which ultimately increases bone mineralization. Pancreatic polypeptide (PP) is secreted by the F (or PP) cells. Catecholamines, usually considered neurotransmitters, are hormones when secreted by the adrenal medulla because they are released into the circulation. Each part has distinct functions, and the glands act independently from one another. As blood glucose levels decrease, the stimulus for insulin secretion also decreases. Describe the purpose, significance of results, and nursing responsibilities related to diagnostic studies of the endocrine system. Parathyroid Hormone. They are an essential part of the body’s “fight or flight” response to stress (see Chapter 7). Glucocorticoids inhibit the inflammatory response and are considered antiinflammatory. Renin is produced by specialized cells of the renal afferent arterioles. This is an example of the lock-and-key model of biochemical reactions. Learn faster with spaced repetition. Norepinephrine (noradrenaline) 48-1 Location of the major endocrine glands. Link age-related changes in the endocrine system to differences in assessment findings. Parathyroid hormone (PTH), or parathormone Aldosterone secretion is regulated by the renin-angiotensin system, serum potassium ion concentration, and adrenocorticotropic hormone (ACTH). Another major effect occurs in peripheral tissues, where insulin facilitates glucose transport into cells, transport of amino acids across muscle membranes and their synthesis into protein, and transport of triglycerides into adipose tissue. May partly explain increased incidence of hypertension with aging. Volume receptors in large veins, heart atria, and carotid arteries that sense pressure changes also contribute to ADH control. Promote growth spurt in adolescence, secondary sex characteristics, and libido in both sexes. Location of the major endocrine glands. Triiodothyronine (T3) For example, stress is sensed or perceived by the CNS with subsequent stimulation of the SNS. The pancreas is a long, tapered, lobular, soft gland located behind the stomach and anterior to the first and second lumbar vertebrae. The adrenal cortex secretes small amounts of androgens that are converted to sex steroids in peripheral tissues: testosterone in men and estrogen in women. This is an endogenous 24-hour rhythm that can be driven and altered by sleep-wake or dark-light 24-hour (diurnal) cycles. cortisol, p. 1140 • Prolactin-releasing factor (PRF) 10 Facts About the Endocrine System Every Nursing Student Should Know The endocrine system is one of two systems that coordinate the functions of the body. The anterior lobe accounts for 80% of the gland by weight and is regulated by the hypothalamus through releasing and inhibiting hormones. The lack of antidiuretic hormone will result in dehydration with resulting hypotension. Calcitonin and PTH regulate calcium balance. 8. Hormones are classified by their chemical structure as either lipid soluble or water soluble. PTH stimulates the transfer of calcium from the bone into the blood and inhibits bone formation, resulting in increased serum calcium and phosphate. Tags: Medical-Surgical Nursing Assessment and Management of Clinical P Our members represent more than 60 professional nursing specialties. Regulates metabolic rate of all cells and processes of cell growth and tissue differentiation. This local effect is called paracrine action. Increased incidence of hypothyroidism with aging. Changes I love seeing that “lightbulb” moment when students realize that they’ve been making the endocrine system a lot harder than it needs to be. This is an endogenous 24-hour rhythm that can be driven and altered by sleep-wake or dark-light 24-hour (diurnal) cycles.
