Ch. 41 Diabetes Insipidus (exam 3) ALL SOLUTION LATEST 2025/2026 EDITION GUARANTEED GRADE A+ The nurse is receiving hand-off reports for four patients. Which patient presents with a serum sodium level consistent with diabetes insipidus (DI)? Patient A -- 148 Patient B -- 140 Patient C -- 136 Patient D -- 128 A Which interventions should the nurse implement when caring for the patient who has undergone a transsphenoidal hypophysectomy? Select all that apply. 1- Conduct a neurological assessment. 2- Maintain the head of the bed at a 30° angle. 3- Provide frequent mouth care. 4- Monitor the nasal drainage pad. 5- Obtain urine-specific gravity every hour. 1,3,4,5 The nurse is providing discharge instructions to a patient and his family after a diagnosis of diabetes insipidus (DI). Which instructions should be included? Select all that apply. 1- "Check body weight daily at the same time and on the same scale." 2- "Report weight changes of more than 5 pounds per day." 3- "Drink plenty of fluids." 4- "Maintain adequate mouth care." 5- "Know that overuse of desmopressin may lead to dehydration." 1,3,4 The patient presents to the emergency department with 1-week symptoms of polyuria, polydipsia, hypernatremia, and tachycardia. The patient has an elevate serum osmolality. A malfunction in which area of the brain is most likely causing these symptoms? 1- Hypothalamus 2- Anterior lobe of the pituitary 3- Posterior pituitary gland 4- Sella turcica 3 Review the events within the health record below. Select the priority request by the nurse when performing a Situation, Background, Assessment, Recommendation (SBAR) communication with the provider. 1-IV D5 and 0.45% NaCl at 200 mL/hr 2-Desmopressin 0.05 mg orally no 3-Daily weight 4-High sodium diet Desmopressin 0.05 mg orally no Rationale: This medication is a synthetic analog of antidiuretic hormone and highly effective in the treatment of acute diabetes insipidus. The nurse is caring for a patient after a transsphenoidal hypophysectomy. Which assessment changes are most concerning? 1- Heart rate is increased. 2- Pulse is full and bounding. 3- Blood pressure is increased. 4- Serum osmolality is decreased. Heart rate is increased. Rationale: Diabetes insipidus is associated with the removal of the posterior pituitary gland. It is caused by decreased secretion of antidiuretic hormone. In such condition, heart rate is increased. The nursing student asks the nurse how central diabetes insipidus (DI) is different from nephrogenic DI. How should the nurse respond? 1- Central DI occurs because the kidneys are resistant to ADH. 2- Central DI is caused by decreased secretion of ADH. 3- Central DI is observed in patients with chronic renal insufficiency. 4- Central DI occurs when the kidneys are unable to concentrate urine. 2 The nursing is caring for a patient with newly diagnosed idiopathic diabetes insipidus (DI). Which of the following should the nurse include in patient teaching? 1-Pineal tumor is commonly the cause. 2-Destruction of the cells of the hypothalamus lead to the condition. 3-Traditional craniotomy is the reason for this. 4-Head trauma often causes the condition. 2 The nursing is admitting a patient from home. Which presenting symptom causes the nurse to be concerned that the patient has developed diabetes insipidus (DI)? 1-Hypertension 2-Bradycardia 3-Polyuria 4-Decreased serum sodium 3 The nurse is concerned about high sodium levels in her patient experiencing diabetes insipidus. Which is the priority nursing action? 1-Supplement the reciprocal hypokalemia. 2-Complete hourly neurological assessments. 3-Provide safety precautions for seizures. 4-Monitor hourly urine output. 3 hypopituitarism - rare, affecting fewer than 200,000 individuals in the US. - anterior pituitary dysfunction is often secondary to a pituitary tumor or damage to the hypothalamus. - increased itracranial pressure secondary to head trauma, CNS infections like meningitis, or brain tumors may also affect perfusion of the hypothalamus and result in damage. - postpartum hemorrhage, resulting in large blood loss and corresponding hypotension, may lead to severe hypo perfusion and infarction of anterior pituitary. - gradual onset, occurs after 70-90% of the anterior pituitary is nonfunctional or destroyed. pathophysiology of hypopituitarism - deficiency of one of the anterior pituitary hormones results in changes in metabolic or sexual function, dependent on which hormone level is decreased. - the increase in one or more of the anterior pituitary hormones determines the patho of hypopituitarism decrease is adrenocorticotropic hypopituitarism A decrease in adrenocorticotropic hormone (A C T H) leads to a decrease in release of the mineralocorticoids (aldosterone) and glucocorticoids (cortisol) from the adrenal cortex. - decrease in thyroid hormones d/t decreases secretion of TSH from anterior pituitary gland hypopituitarism - . Alterations in sexual and reproductive functioning are caused by decreased secretion of the gonadotropins, luteinizing hormone (LH), and follicle-stimulating hormone (FSH). There is also a decrease in growth hormone that presents differently according to the age of the patient. In children before the closure of the epiphyses, dwarfism (small stature) develops. A lack of growth hormone in adults does not affect bone length but does affect bone density, and osteoporosis (reduction in bone density) may develop. ACTH Adrenocorticotropic hormone - decreased glucocorticoids leads to: hypoglycemia, decreased cortisol levels, and decreased ability to handle stress - decreased mineralocorticoids leads to: Hyponatremia, hypotension, hyperkalemia growth hormone hypopituitarism - decreased bone density - decreased muscle strength - increased risk of bone fractures lutenizing hormone hypopituitarism in females: irregular menses or amenorrhea as well as decreased ovulation - in males: decreased testosterone growth hormone hormone secreted by anterior pituitary gland that stimulates growth of bones Lutenizing (LH) Stimulates ovulation; testosterone synthesis Follicle-stimulating hormone (FSH) secreted by the pituitary gland to stimulate maturation of the egg cell (ovum) FSH hypopituitarism in females: decreased estrogen production and well as decreased ovulation in males: decreased sperm production Adrenocorticotropic hormone stimulates the growth and secretions of the adrenal cortex thyroid-stimulating hormone stimulates thyroid gland (TSH) TSH hypopituitarism - decreased levels of T3 and T4 - decreased metabolic rate - weight gain - thinning of hair - decreased libido medical diagnostics for all hypopituitarism types - ACTH stimulation test - TSH, FSH, LH, prolactin, and growth hormone tests - CT scan - MRI Hormonal studies conducted to assess for hypopituitarism include the A C T H (Cortrosyn) stimulation test and measurements of T S H, FSH, LH, prolactin, and growth hormone provocative tests. If a tumor of the brain or pituitary is suspected, a head computed tomography (C T) or M R I may be completed. A battery of serum studies related to effects on target glands or cells is also performed to assist in a definitive diagnosis based on physical presentation. With suspected abnormalities in growth hormone, manifested by complaints of weakness or pathologic bone fractures, diagnostic evaluation often focuses on ruling-out other causes. Direct measurement of growth hormone is difficult because the levels change throughout the course of a day medications for hypopituitarism The goals of medical management of hypopituitarism are aimed at restoring target hormone levels to normal levels. Hormone replacement is guided by the specific hormone deficiency. In addition to hormone replacement, supportive therapies such as fluid and electrolyte replacement are the key to managing the patient with hypopituitarism. Hormone replacement may include cortisol, thyroid hormone, testosterone, or estrogen. Management of a decrease in growth hormone is usually focused on the pathophysiological processes associated with decreased bone density and osteoporosis and includes ensuring adequate intake or supplementation with vitamin D and calcium. complications of hypopituitarism Patients with hypopituitarism may develop life-threatening emergencies, particularly with panhypopituitarism. Lack of A C T H with a resultant decrease in glucocorticoids and mineralocorticoids is a life-threatening emergency because the patient is unable to maintain adequate fluid volume status, which may lead to circulatory collapse. Additionally, a lack of T S H, leading to a decrease in thyroid hormone secretion, may result in a severe decrease in metabolism that affects all body functions and is particularly dangerous in relation to metabolism of medications. general signs and symptoms of hypopituitarism Clinical manifestations observed in the patient with hypopituitarism are directly related to the specific hormone deficiency. Common findings may include: Hypoglycemia related to decreased secretion of A C T H, resulting in decreased secretion of cortisol Decreased ability to cope with stress secondary to decreased secretion of cortisol Hyponatremia and hypotension secondary to decreased aldosterone secretion Hyperkalemia secondary to decreased aldosterone secretion Decreased bone density secondary to decreased growth hormone secretion assessments for hypopituitarism Vital signs — Hypotension and tachycardia develop secondary to decreased secretion of A C T H, leading to decreased secretion of glucocorticoid and mineralocorticoid, resulting in sodium and water loss. Changes in fertility — Decreased testosterone may lead to sterility in males. Decreased LH or FSH may lead to amenorrhea and infertility in females. Signs of decreased bone density — A lack of growth hormone in adults affects bone density, and the patient is at risk for osteoporosis. actions for hypopituitarism Implement safety measures — Risk of injury related to falls and pathologic fractures increases secondary to decreased secretion of growth hormone. Increase vitamin D and calcium intake — Treats osteoporosis secondary to decreased growth hormone; vitamin D promotes absorption of calcium in the gastrointestinal tract. Hormone replacement — Supplementation of sex hormones may be administered to treat hypofunction of the gonads. Collaborate with physical therapy to maximize mobility — Osteoporosis increases the risk for falls, and the physical therapist can provide input into safe transfers from bed to chair and measures to decrease the incidence of falls. teachings for hypopituitarism Signs and symptoms of acute adrenal insufficiency — Infection, injury, and stress lead to an increased need for A C T H. Because of underlying hypopituitarism, the patient may require exogenous glucocorticoids in the event of stress (physiological or psychological). Importance of taking hormone supplements in the morning — Taking hormone supplements in the morning mimics the normal release of these hormones evaluating care outcomes for hypopituitarism Patients with hypopituitarism can achieve relatively normal function by complying with prescribed therapy. Replacement hormone therapy based on the specific hormone is combined with supportive treatment to address end gland/target cell effects. Vital signs within normal limits, improved mobility, stable weight, and normal fluid volume status are indicative of stable anterior pituitary function. With appropriate hormone replacement, fertility and conception may be achieved. During periods of stress, such as invasive procedures, the patient needs to be aware of the signs of adrenal insufficiency and the clinical manifestations they should report to their healthcare provider. Hyperpituitarism Hyperpituitarism is usually related to a hypersecreting tumor. The incidence of these types of tumors is higher in females, but there are no differences based on race or ethnicity. These types of tumors may present in children or adults, and there is a genetic association with the tumor development. The patient presentation is consistent with clinical manifestations associated with the oversecreted hormone, and the tumor itself may lead to headaches or visual changes secondary to compression of the optic nerve (CN II) and other structures in the central nervous system pathophysiology of hyperpituitarism Hyperpituitarism secondary to hypersecretion of hormones leads to specific dysfunction related to the hormone involved. An excess of one of the anterior pituitary hormones results in changes in metabolic or sexual function that are dependent on which hormone level is elevated. The effects of an increase in one or more of the anterior pituitary hormones determine the pathophysiology of hyperpituitarism. An increase in A C T H leads to an increase in release of the mineralocorticoids and glucocorticoids from the adrenal cortex. Likewise, there is an increase in thyroid hormone released secondary to the increased secretion of T S H from the anterior pituitary gland. Alterations in sexual and reproductive functioning are caused by increased secretion of the gonadotropins (LH and FSH). There is also an increase in growth hormone that presents differently according to the age of the patient. In children before the closure of the epiphyses, gigantism (large stature) develops. An excess of growth hormone in adults does not affect bone length because of closure of the epiphyses but does affect bone density, and acromegaly (thickening of bones, particularly of the hands, feet, and facial bones) may develop (Fig. 41.1). Acromegaly/Gigantism -Hypersecretion of the pituitary GH over a long period of time Etiology: secondary to a benign tumor of the pituitary gland. Patho: pituitary tumor secrete GH & prolactin; stim growth of bones Clinical Manifestations: vision changes, oily skin, hirsutism, difficulty speaking, larger tongue, feet grow, galactorrhea, gynecomastia Diagnostic Tests: serum GH, Somatomedin C (SM-C), Xray, MRI Planning & Implementation: Give Octreotide (Sandostatin) 20 mg IM Q4Weeks signs and symptoms of acromegaly - headache - supraorbital bulging - thickening and broadening of bone - broadened nose - enlarged tongue and lips - coarse features - thyroid gland hypertrophy - cardiomegaly - increased perspiration - galactorrhea - hepatomegaly - splenomegaly - carpal tunnel syndrome - enlarged colon - enlarged hands - osteoarthritis - enlarged feet (breadth) ACTH hyperpituitarism - increased glucocorticoids (hyperglycemia and increased cortisol level) - increased mineralcorticoids (hypernatremia, hypertension, hypokalemia) Growth hormone hyperpituitarism ‒Increased bone density ‒Coarse facial features ‒Menstrual irregularities TSH hyperpituitarism •Increased levels of T3 and T4 ‒Increased metabolic rate ‒Weight loss Exophthalmos diagnosis for hyperpituitarism Diagnostic evaluation of hyperpituitarism focuses on the particular hormone and target cells/glands affected by the excess of tropic hormone. Hormonal studies conducted to assess for hyperpituitarism include the A C T H (Cortrosyn) stimulation test and measurements of T S H, FSH, LH, prolactin, and growth hormone provocative tests. If a hypersecreting tumor of the brain or pituitary is suspected, a head C T or M R I may be completed. A battery of serum studies associated with effects on target glands or cells is also performed to assist in a definitive diagnosis based on physical presentation. With suspected increases in growth hormone, the patient presents with increases in the size of the hands and feet and broadening of the facial bones. CONTINUED..
