A nurse is teaching a client with adrenal insufficiency about corticosteroids. Which statement by the client indicates a need for additional teaching? "I will avoid friends and family members who are sick." "I will eat lots of chicken and dairy products." "I may stop taking this medication when I feel better." "I will see my ophthalmologist regularly for a check-up."

"I may stop taking this medication when I feel better." The client requires additional teaching because he states that he may stop taking corticosteroids when he feels better. Corticosteroids should be gradually tapered by the physician. Tapering the corticosteroid allows the adrenal gland to gradually resume functioning. Corticosteroids increase the risk of infection and may mask the early signs of infection, so the client should avoid people who are sick. Corticosteroids cause muscle wasting in the extremities, so the client should increase his protein intake by eating foods such as chicken and dairy products. Corticosteroids have been linked to glaucoma and corneal lesions, so the client should visit his ophthalmologist regularly.

A nurse is caring for a client who was recently diagnosed with hyperparathyroidism. Which statement by the client indicates the need for additional discharge teaching? "I will take my pain medications according to the schedule we developed." "I will increase my fluid and calcium intake." "I'll schedule a follow-up visit with my physician as soon as I get home." "I'll call my physician if I notice tingling around my lips."

"I will increase my fluid and calcium intake." The client requires additional teaching if he states that he will increase his calcium intake. Hyperparathyroidism causes extreme increases in serum calcium levels. The client should increase his fluid intake, but he should limit his calcium and vitamin D intake. The client should continue to take pain mediations as scheduled and have regular follow-up visits with his physician. Tingling around the lips is a sign of hypercalcemia and should be reported to the physician immediately.

Evaluation of an adult client reveals oversecretion of growth hormone. Which of the following would the nurse expect to find? Excessive urine output Weight loss Bulging forehead Constant thirst

Bulging forehead Oversecretion of growth hormone in an adult results in acromegaly, manifested by coarse features, a huge lower jaw, thick lips, thickened tongue, a bulging forehead, bulbous nose, and large hands and feet. Excessive urine output, weight loss, and constant thirst are associated with diabetes insipidus.

The primary function of the thyroid gland includes which of the following? Control of cellular metabolic activity Facilitation of milk ejection Reabsorption of water Reduction of plasma level of calcium

Control of cellular metabolic activity The primary function of the thyroid hormone is to control cellular metabolic activity. Oxytocin facilitates milk ejection during lactation and increases the force of uterine contraction during labor and delivery. Antidiuretic hormone (ADH) release results in reabsorption of water into the bloodstream rather than excretion by the kidneys. Calcitonin reduces the plasma level of calcium by increasing its deposition in bone.

Which is a clinical manifestation of diabetes insipidus? Low urine output Excessive thirst Weight gain Excessive activities

Excessive thirst Urine output may be as high as 20 L in 24 hours. Thirst is excessive and constant. Activities are limited by the frequent need to drink and void. Weight loss develops.

A client is being seen in the clinic to receive the results of the lab work to determine thyroid levels. The nurse observes the client's eyes appear to be bulging, and there is swelling around the eyes. What does the nurse know that the correct documentation of this finding is? Retinal detachment Periorbital swelling Bulging eyes Exophthalmos

Exophthalmos Exophthalmos is an abnormal bulging or protrusion of the eyes and periorbital swelling. These findings are not consistent with retinal detachment.

A client is having chronic pain from arthritis. What type of hormone is released in response to the stress of this pain that suppresses inflammation and helps the body withstand stress? Testosterone Mineralocorticoids Glucocorticoids Estrogen

Glucocorticoids Glucocorticoids, such as cortisol, affect body metabolism, suppress inflammation, and help the body withstand stress. Mineralocorticoids, primarily aldosterone, maintain water and electrolyte balances. The androgenic hormones convert to testosterone and estrogens.

x A woman with a progressively enlarging neck comes into the clinic. She mentions that she has been in a foreign country for the previous 3 months and that she didn't eat much while she was there because she didn't like the food. She also mentions that she becomes dizzy when lifting her arms to do normal household chores or when dressing. What endocrine condition should the nurse expect the health care provider to diagnose? Diabetes mellitus Goiter Diabetes insipidus Cushing's syndrome

Goiter A goiter can result from inadequate dietary intake of iodine associated with changes in foods or malnutrition. It's caused by insufficient thyroid gland production and depletion of glandular iodine. Signs and symptoms of goiter include an enlarged thyroid gland, dizziness when raising the arms above the head, dysphagia, and respiratory distress. Signs and symptoms of diabetes mellitus include polydipsia, polyuria, and polyphagia. Signs and symptoms of diabetes insipidus include extreme polyuria (4 to 16 L/day) and symptoms of dehydration (poor tissue turgor, dry mucous membranes, constipation, dizziness, and hypotension). Cushing's syndrome causes buffalo hump, moon face, irritability, emotional lability, and pathologic fractures.

A middle-aged female client complains of anxiety, insomnia, weight loss, the inability to concentrate, and eyes feeling "gritty." Thyroid function tests reveal the following: thyroid-stimulating hormone (TSH) 0.02 U/ml, thyroxine 20 g/dl, and triiodothyronine 253 ng/dl. A 6-hour radioactive iodine uptake test showed a diffuse uptake of 85%. Based on these assessment findings, the nurse should suspect: thyroiditis. Graves' disease. Hashimoto's thyroiditis. multinodular goiter.

Graves' disease. Graves' disease, an autoimmune disease causing hyperthyroidism, is most prevalent in middle-aged females. In Hashimoto's thyroiditis, the most common form of hypothyroidism, TSH levels would be high and thyroid hormone levels low. In thyroiditis, radioactive iodine uptake is low (?2%), and a client with a multinodular goiter will show an uptake in the high-normal range (3% to 10%).

The nurse is assessing a client in the clinic who appears restless, excitable, and agitated. The nurse observes that the client has exophthalmos and neck swelling. What diagnosis do these clinical manifestations correlate with? Hypothyroidism Hyperthyroidism Syndrome of inappropriate antidiuretic hormone secretion (SIADH) Diabetes insipidus (DI)

Hyperthyroidism Clients with hyperthyroidism characteristically are restless despite feeling fatigued and weak, highly excitable, and constantly agitated. Fine tremors of the hand occur, causing unusual clumsiness. The client cannot tolerate heat and has an increased appetite but loses weight. Diarrhea also occurs. Visual changes, such as blurred or double vision, can develop. Exophthalmos, seen in clients with severe hyperthyroidism, results from enlarged muscle and fatty tissue surrounding the rear and sides of the eyeball. Neck swelling caused by the enlarged thyroid gland often is visible. Hypothyroidism clinical manifestations are the opposite of what is seen as hyperthyroidism. SIADH and DI clinical manifestations do not correlate with the symptoms manifested by the client.

The nurse is aware that the clinical symptoms of a patient with hypoparathyroidism are the result of the initial physiologic response of: Hypocalcemia. Decreased levels of vitamin D. Increased serum levels of phosphate. Cardiac arrhythmias.

Hypocalcemia. Hypoparathyroidism results in hypocalcemia, which triggers a series of physiologic responses, including the choices presented.

A client with acromegaly has been given the option of a surgical approach or a medical approach. The client decides to have a surgical procedure to remove the pituitary gland. What does the nurse understand this surgical procedure is called? Hypophysectomy Hysteroscopy Thyroidectomy Ablation

Hypophysectomy The treatment of choice is surgical removal of the pituitary gland (transsphenoidal hypophysectomy) through a nasal approach. The surgeon may substitute an endoscopic technique using microsurgical instruments to reduce surgical trauma. A hysteroscopy is a gynecologic procedure. The thyroid gland is not involved for a surgical procedure. Ablation is not a removal of the pituitary gland.

A client has been diagnosed with myxedema from long-standing hypothyroidism. What clinical manifestations of this disorder does the nurse recognize are progressing to myxedema coma? Select all that apply. Hypothermia Hypertension Hypotension Hypoventilation Hyperventilation

Hypothermia Hypotension Hypoventilation Severe hypothyroidism is called myxedema. Advanced, untreated myxedema can progress to myxedemic coma. Signs of this life-threatening event are hypothermia, hypotension, and hypoventilation. Hypertension and hyperventilation indicate increased metabolic responses, which are the opposite of what the client would be experiencing.

A client is suspected to have a pituitary tumor due to signs of diabetes insipidus. What initial test does the nurse help to prepare the client for? Magnetic resonance imaging (MRI) Radioactive iodine uptake test Radioimmunoassay A nuclear scan

Magnetic resonance imaging (MRI) A computed tomography (CT) or magnetic resonance imaging (MRI) scan is performed to detect a suspected pituitary tumor or to identify calcifications or tumors of the parathyroid glands. A radioactive iodine uptake test would be useful for a thyroid tumor. Radioimmunoassay determines the concentration of a substance in plasma.

A client with pheochromocytoma is scheduled for an adrenalectomy. Which of the following would the nurse perform preoperatively? Begin administering prescribed corticosteroid. Initiate intravenous access for fluid therapy. Monitor blood pressure (BP) frequently. Check for the signs of adrenal insufficiency.

Monitor blood pressure (BP) frequently. The nurse should monitor BP frequently before surgery when a client has a pheochromocytoma. When bilateral adrenalectomy is scheduled, the nurse may start IV administration of a solution containing a corticosteroid preparation the morning of surgery. Some surgeons prefer to initiate corticosteroid administration during removal of the adrenals. The nurse monitors for signs of adrenal insufficiency after the surgery.

A patient with a history of hypothyroidism is admitted to the intensive care unit unconscious and with a temperature of 95.2ºF. A family member informs the nurse that the patient has not taken thyroid medication in over 2 months. What does the nurse suspect that these findings indicate? Thyroid storm Myxedema coma Diabetes insipidus Syndrome of inappropriate antidiuretic hormone (SIADH)

Myxedema coma Myxedema coma is a rare life-threatening condition. It is the decompensated state of severe hypothyroidism in which the patient is hypothermic and unconscious (Ross, 2012a). This condition may develop with undiagnosed hypothyroidism and may be precipitated by infection or other systemic disease or by use of sedatives or opioid analgesic agents. Patients may also experience myxedema coma if they forget to take their thyroid replacement medication.

A client receiving thyroid replacement therapy develops influenza and forgets to take her thyroid replacement medicine. The nurse understands that skipping this medication puts the client at risk for developing which life-threatening complication? Exophthalmos Thyroid storm Myxedema coma Tibial myxedema

Myxedema coma Myxedema coma, severe hypothyroidism, is a life-threatening condition that may develop if thyroid replacement medication isn't taken. Exophthalmos (protrusion of the eyeballs) is seen with hyperthyroidism. Although thyroid storm is life-threatening, it's caused by severe hyperthyroidism. Tibial myxedema (peripheral mucinous edema involving the lower leg) is associated with hypothyroidism but isn't life-threatening.

The nurse is preparing a client for a thyroid test. Which medications that the client is taking should be documented on the laboratory slip as possibly affecting the thyroid test? Phenytoin Metoclopramide Lisinopril Furosemide Amphetamine

Phenytoin Metoclopramide Furosemide Amphetamine If a client has recently taken a drug that contains iodine or has had radiographic contrast studies that used iodine, thyroid test results may be inaccurate. Other drugs also affect the results of thyroid tests. Phenytoin can lower T4 values. Metoclopramide can raise TSH levels. Amphetamine can lower TSH levels. Furosemide can increase T4 level. Be sure to enter on the laboratory request slip all drugs the client is taking or has taken within the past 3 months. The other drugs do not have relevance to the thyroid test.

The nurse is caring for a client with hypoparathyroidism. When the nurse taps the client's facial nerve, the client's mouth twitches and the jaw tightens. What is this response documented as related to the low calcium levels? Positive Chvostek's sign Positive Trousseau's sign Positive paresthesias Positive Babinski's sign

Positive Chvostek's sign If a nurse taps the client's facial nerve (which lies under the tissue in front of the ear), the client's mouth twitches and the jaw tightens. The response is identified as a positive Chvostek's sign. A positive Trousseau's sign is elicited by placing a BP cuff on the upper arm, inflating it between the systolic and diastolic BP, and waiting 3 minutes. The nurse observes the client for spasm of the hand (carpopedal spasm), which is evidenced by the hand flexing inward. Positive Babinski's sign is elicited by stroking the sole of the foot. Paresthesia is not a symptom that can be elicited; it is felt by the client.

While assessing a client with hypoparathyroidism, the nurse taps the client's facial nerve and observes twitching of the mouth and tightening of the jaw. The nurse would document this finding as which of the following? Positive Trousseau's sign Positive Chvostek's sign Hyperactive deep tendon reflex Tetany

Positive Chvostek's sign If a nurse taps the client's facial nerve (which lies under the tissue in front of the ear), the client's mouth twitches and the jaw tightens. The response is identified as a positive Chvostek's sign. The nurse may elicit a positive Trousseau's sign by placing a BP cuff on the upper arm, inflating it between the systolic and diastolic BP, and waiting 3 minutes. The nurse observes the client for spasm of the hand (carpopedal spasm), which is evidenced by the hand flexing inward. Deep tendon reflexes include the biceps, brachioradialis, triceps, and patellar reflexes. Tetany would be manifested by reports of numbness and tingling in the fingers or toes or around the lips, voluntary movement that may be followed by an involuntary, jerking spasm, and muscle cramping. Tonic (continuous contraction) flexion of an arm or a finger may occur.

A client has a decreased level of thyroid hormone being excreted. What will the feedback loop do to maintain the level of thyroid hormone required to maintain homeostatic stability? Stimulate more hormones using the negative feedback system Stimulate more hormones using the positive feedback system Produce a new hormone to try and regulate the thyroid function The feedback loop will be unable to perform in response to low levels of thyroid hormone.

Stimulate more hormones using the negative feedback system Feedback can be either negative or positive. Most hormones are secreted in response to negative feedback; a decrease in levels stimulates the releasing gland.

A postpartum client is receiving intravenous oxytocin (Pitocin) after birth. Why will this medication be used for this client after the birth of her child? Will prevent lactation for a woman who is bottle feeding her newborn Decreases the postpartum cramping Helps treat nausea Stimulates the contraction of the uterus and prevents bleeding

Stimulates the contraction of the uterus and prevents bleeding Oxytocin (Pitocin) is released from the pituitary gland and stimulates contraction of pregnant uterus and release of breast milk after childbirth. It will not prevent lactation or help treat nausea. It will increase lactation.

A nurse is assessing a client after a thyroidectomy. The assessment reveals muscle twitching and tingling, along with numbness in the fingers, toes, and mouth area. The nurse should suspect which complication? Tetany Hemorrhage Thyroid storm Laryngeal nerve damage

Tetany Tetany may result if the parathyroid glands are excised or damaged during thyroid surgery. Hemorrhage is a potential complication after thyroid surgery but is characterized by tachycardia, hypotension, frequent swallowing, feelings of fullness at the incision site, choking, and bleeding. Thyroid storm is another term for severe hyperthyroidism — not a complication of thyroidectomy. Laryngeal nerve damage may occur postoperatively, but its signs include a hoarse voice and, possibly, acute airway obstruction.

A client who is frightened of needles has been told that he will have to have an intravenous (IV) line inserted. The client's blood pressure and pulse rate increase, and the nurse observes the pupils dilating. What does the nurse recognize has occurred with this client? The client is developing an infection. The client is having a response to dehydration. The client is in a hypertensive crisis. The client is showing the fight-or-flight response.

The client is showing the fight-or-flight response. The adrenal medulla secretes epinephrine and norepinephrine. These two hormones are released in response to stress or threat to life. They facilitate what is referred to as the physiologic stress response, also known as the fight-or-flight response. Many organs respond to the release of epinephrine and norepinephrine. Responses include increased blood pressure and pulse rate, dilation of the pupils, constriction of blood vessels, bronchodilation, and decreased peristalsis. The client does not demonstrate the signs of infection, dehydration, or hypertensive crisis.

A client is scheduled for a diagnostic test to measure blood hormone levels. The nurse expects that this test will determine which of the following? The concentration of a substance in plasma Details about the size of the organ and its location The functioning of endocrine glands The client's blood sugar level

The functioning of endocrine glands Measuring blood hormone levels helps determine the functioning of endocrine glands. A radioimmunoassay determines the concentration of a substance in plasma. The measurement of blood hormone levels will not reveal a client's blood sugar level. Radiographs of the chest or abdomen determine the size of the organ and its location.

When describing the difference between endocrine and exocrine glands, which of the following would the instructor include as characteristic of endocrine glands? The secretions are released directly into the blood stream. The glands contain ducts that produce the hormones. The secreted hormones act like target cells. The glands play a minor role in maintaining homeostasis.

The secretions are released directly into the blood stream. The endocrine glands secrete hormones, chemicals that accelerate or slow physiologic processes, directly into the bloodstream. This characteristic distinguishes endocrine glands from exocrine glands, which release secretions into a duct. Hormones circulate in the blood until they reach receptors in target cells or other endocrine glands. They play a vital role in regulating homeostatic processes.

A nurse explains the role of the ovaries. Which hormones would be included in that discussion? estrogen and progesterone estrogen and progestin testosterone and progesterone estrogen and testosterone

estrogen and progesterone The ovaries produce estrogen and progesterone. Progestin is a synthetic compound. Testosterone is involved with the development and maintenance of male secondary sex characteristics, such as facial hair and a deep voice.

Hyperthyroidism is caused by increased levels of thyroxine in blood plasma. A client with this endocrine dysfunction experiences: heat intolerance and systolic hypertension. weight gain and heat intolerance. diastolic hypertension and widened pulse pressure. anorexia and hyperexcitability.

heat intolerance and systolic hypertension. An increased metabolic rate in a client with hyperthyroidism caused by excess serum thyroxine leads to systolic hypertension and heat intolerance. Weight loss — not gain — occurs because of the increased metabolic rate. Diastolic blood pressure decreases because of decreased peripheral resistance. Heat intolerance and widened pulse pressure can occur but systolic hypertension and diastolic hypertension don't. Clients with hyperthyroidism experience an increase in appetite — not anorexia.

A client is undergoing diagnostics for an alteration in thyroid function. What physiologic function is affected by altered thyroid function? metabolic rate growth fluid/electrolyte balance sleep/wake cycles

metabolic rate The thyroid concentrates iodine from food and uses it to synthesize thyroxine (T4) and triiodothyronine (T3). These two hormones regulate the body's metabolic rate.

An incoherent client with a history of hypothyroidism is brought to the emergency department by the rescue squad. Physical and laboratory findings reveal hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and periorbital area. Knowing that these findings suggest severe hypothyroidism, the nurse prepares to take emergency action to prevent the potential complication of: thyroid storm. cretinism. myxedema coma. Hashimoto's thyroiditis.

myxedema coma. Severe hypothyroidism may result in myxedema coma, in which a drastic drop in the metabolic rate causes decreased vital signs, hypoventilation (possibly leading to respiratory acidosis), and nonpitting edema. Thyroid storm is an acute complication of hyperthyroidism. Cretinism is a form of hypothyroidism that occurs in infants. Hashimoto's thyroiditis is a common chronic inflammatory disease of the thyroid gland in which autoimmune factors play a prominent role.
