Med Surg 2 Ch 45: Assessment and Management of Patients with Endocrine Disorders

A client with Cushing syndrome is admitted to the hospital. During the initial assessment, the client tells the nurse, "The worst thing about this disease is how awful I look. I want to cry every time I look in the mirror." Which statements by the nurse is the best response?

"If treated successfully, the major physical changes will disappear with time." If treated successfully, the major physical changes associated with Cushing syndrome disappear with time. The client may benefit from discussion of the effect the changes have had on his or her self-concept and relationships with others. Weight gain and edema may be modified by a low-carbohydrate, low-sodium diet, and a high protein intake may reduce some of the other bothersome symptoms.

Which of the following hormones controls secretion of adrenal androgens?

Adrenocorticotropic hormone (ACTH) ACTH controls the secretion of adrenal androgens. When secreted in normal amounts, the adrenal androgens appear to have little effect, but when secreted in excess, as in certain inborn enzyme deficiencies, masculinization may result. The secretion of T3 and T4 by the thyroid gland is controlled by TSH. Parathormone regulates calcium and phosphorous metabolism. Calcitonin reduces the plasma level of calcium by increasing its deposition in bone.

What is the most common cause of hyperaldosteronism?

An adrenal adenoma An autonomous aldosterone-producing adenoma is the most common cause of hyperaldosteronism. Hyperplasia is the second most frequent cause. Aldosterone secretion is independent of sodium and potassium intake and pituitary stimulation.

A patient is suspected of having a pheochromocytoma and is having diagnostic tests done in the hospital. What symptoms does the nurse recognize as most significant for a patient with this disorder?

Blood pressure varying between 120/86 and 240/130 mm Hg Hypertension associated with pheochromocytoma may be intermittent or persistent. Blood pressures exceeding 250/150 mm Hg have been recorded. Such blood pressure elevations are life threatening and can cause severe complications, such as cardiac dysrhythmias, dissecting aneurysm, stroke, and acute kidney failure.

Accidental removal of one or both parathyroid glands can occur during a thyroidectomy. Which of the following is used to treat tetany?

Calcium gluconate Sometimes in thyroid surgery, the parathyroid glands are removed, producing a disturbance in calcium metabolism. Tetany is usually treated with IV calcium gluconate. Synthroid is used in the treatment of hypothyroidism. PTU and Tapazole are used in the treatment of hyperthyroidism.

Trousseau's sign is elicited by which of the following?

Carpopedal spasm is induced by occluding the blood flow to the arm for 3 minutes with the use of a blood pressure cuff. A positive Trousseau's sign is suggestive of latent tetany. A positive Chvostek's sign is demonstrated when a sharp tapping over the facial nerve just in front of the parotid gland and anterior to the ear causes spasm or twitching of the mouth, nose, and eye. A positive Allen's test is demonstrated by the palm remaining blanched with the radial artery occluded. A positive Homans' sign is demonstrated when the patient complains of pain in the calf when his foot is dorsiflexed.

What interventions can the nurse encourage the client with diabetes insipidus to do in order to control thirst and compensate for urine loss?

Consume adequate amounts of fluid. The nurse teaches the client to consume sufficient fluid to control thirst and to compensate for urine loss. The client will not be required to come in daily for IV fluid therapy. The client should not limit fluid intake at night if thirst is present. Weighing daily will not control thirst or compensate for urine loss.

A client with hypofunction of the adrenal cortex has been admitted to the medical unit. What would the nurse most likely find when assessing this client?

Decreased blood pressure Decreased blood pressure may occur with hypofunction of the adrenal cortex. Decreased function of the adrenal cortex does not affect the client's body temperature, urine output, or skin tone.

A patient has been diagnosed with thyroidal hypothyroidism. The nurse knows that this diagnosis is consistent with which of the following?

Dysfunction of the thyroid gland itself Thyroidal hypothyroidism results from thyroid gland dysfunction. The other causes result in central, secondary, or tertiary causes if there is inadequate secretion of TSH.

A health care provider suspects that a thyroid nodule may be malignant. The nurse knows to prepare information for the patient based on the usual test that will be ordered to establish a diagnosis. What is that test?

Fine-needle biopsy of the thyroid gland Fine needle biopsy of the thyroid gland is often used to establish the diagnosis of thyroid cancer. The purpose of the biopsy is to differentiate cancerous thyroid nodules from noncancerous nodules and to stage the cancer if detected. The procedure is safe and usually requires only a local anesthetic.

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?

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.

The nurse is aware that the clinical symptoms of a patient with hypoparathyroidism are the result of the initial physiologic response of:

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

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 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.

Following a thyroidectomy, a client exhibits signs of tetany. The nurse anticipates administering which medication?

IV calcium gluconate Usually tetany is treated with IV calcium gluconate. Methimazole, propylthiouracil, and potassium iodide are agents used to treat hyperthyroidism.

The nurse knows to assess a patient with hyperthyroidism for the primary indicator of:

Intolerance to heat With hypothyroidism, the individual is sensitive to cold because the core body temperature is usually below 98.6°F. Intolerance to heat is seen with hyperthyroidism.

Which of the following glands is considered the master gland?

Pituitary Commonly referred to as the master gland, the pituitary gland secretes hormones that control the secretion of additional hormones by other endocrine glands. The thyroid, parathyroid, and adrenal glands are not considered the master gland.

A client is returned to his room after a subtotal thyroidectomy. Which piece of equipment is most important for the nurse to keep at the client's bedside?

Tracheostomy set After a subtotal thyroidectomy, swelling of the surgical site (the tracheal area) may obstruct the airway. Therefore, the nurse should keep a tracheostomy set at the client's bedside in case of a respiratory emergency. Although an indwelling urinary catheter and a cardiac monitor may be used for a client after a thyroidectomy, the tracheostomy set is more important. A humidifier isn't indicated for this client.

For a client with hyperthyroidism, treatment is most likely to include:

a thyroid hormone antagonist. Thyroid hormone antagonists, which block thyroid hormone synthesis, combat increased production of thyroid hormone. Treatment of hyperthyroidism also may include radioiodine therapy, which destroys some thyroid gland cells, and surgery to remove part of the thyroid gland; both treatments decrease thyroid hormone production. Thyroid extract, synthetic thyroid hormone, and emollient lotions are used to treat hypothyroidism.

A client is being evaluated for hypothyroidism. During assessment, the nurse should stay alert for:

decreased body temperature and cold intolerance. Hypothyroidism markedly decreases the metabolic rate, causing a reduced body temperature and cold intolerance. Other signs and symptoms include dyspnea, hypoventilation, bradycardia, hypotension, anorexia, constipation, decreased intellectual function, and depression. Exophthalmos; conjunctival redness; flushed, warm, moist skin; and a systolic murmur at the left sternal border are typical findings in a client with hyperthyroidism.

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:

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.

Cardiac effects of hyperthyroidism include

palpitations. Cardiac effects may include sinus tachycardia, increased pulse pressure, and palpitations. Systolic BP is elevated.

Cardiac effects of hyperthyroidism include

palpitations. Cardiac effects may include sinus tachycardia, increased pulse pressure, and palpitations. Systolic blood pressure is elevated.

A nurse is caring for a client with a kidney disorder. What hormone released by the kidneys initiates the production of angiotensin and aldosterone to increase blood pressure and blood volume?

renin Renin is released from the kidneys and initiates the production of angiotensin and aldosterone to increase blood pressure and blood volume. The kidneys secrete erythropoietin, a substance that promotes the maturation of red blood cells. Cholecystokinin released from cells in the small intestine stimulates contraction of the gallbladder to release bile when dietary fat is ingested. Gastrin is released within the stomach to increase the production of hydrochloric acid.

A nurse is instructing a client with newly diagnosed hypoparathyroidism about the regimen used to treat this disorder. The nurse should state that the physician probably will order daily supplements of calcium and:

vitamin D. Typically, clients with hypoparathyroidism are ordered daily supplements of vitamin D along with calcium because calcium absorption from the small intestine depends on vitamin D. Hypoparathyroidism doesn't cause a deficiency of folic acid, potassium, or iron. Therefore, the client doesn't require daily supplements of these substances to maintain a normal serum calcium level.

A female client with hyperglycemia who weighs 210 lb (95 kg) tells the nurse that her husband sleeps in another room because her snoring keeps him awake. The nurse notices that the client has large hands and a hoarse voice. Which disorder would the nurse suspect as a possible cause of the client's hyperglycemia?

Acromegaly Acromegaly, which is caused by a pituitary tumor that releases excessive growth hormone, is associated with hyperglycemia, hypertension, diaphoresis, peripheral neuropathy, and joint pain. Enlarged hands and feet are related to lateral bone growth, which is seen in adults with this disorder. The accompanying soft tissue swelling causes hoarseness and, commonly, sleep apnea. Type 1 diabetes is usually seen in children, and newly diagnosed persons are usually very ill and thin. Hypothyroidism and growth hormone deficiency aren't associated with hyperglycemia.

Evaluation of an adult client reveals oversecretion of growth hormone. Which of the following would the nurse expect to find?

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.

A young client has a significant height deficit and is to be evaluated for diagnostic purposes. What could be the cause of this client's disorder?

pituitary disorder Pituitary disorders usually result from excessive or deficient production and secretion of a specific hormone. Dwarfism occurs when secretion of growth hormone is insufficient during childhood.
