ENDOCRINE PART #1

Which medication order should the nurse question in the client diagnosed with untreated hypothyroidism? 1. Thyroid hormones. 2. Oxygen. 3. Sedatives. 4. Laxatives.

.3 Untreated hypothyroidism is characterized by an increased susceptibility to the effects of most hypnotic and sedative agents; therefore, the nurse should question this medication.

Which signs/symptoms should make the nurse suspect the client is experiencing a thyroid storm? 1. Obstipation and hypoactive bowel sounds. 2. Hyperpyrexia and extreme tachycardia. 3. Hypotension and bradycardia. 4. Decreased respirations and hypoxia.

ANS : 2 1. These are signs of myxedema (hypothyroidism) coma. Obstipation is extreme constipation. 2. Hyperpyrexia (high fever) and heart rate above 130 beats per minute are signs of thyroid storm, a severely exaggerated hyperthyroidism. 3. Decreased blood pressure and slow heart rate are signs of myxedema coma. 4. These are signs/symptoms of myxedema coma.

The nurse is preparing to administer the following medications. Which medication should the nurse question administering? 1. The thyroid hormone to the client who does not have a T3, T4 level. 2. The regular insulin to the client with a blood glucose level of 210 mg/dL. 3. The loop diuretic to the client with a potassium level of 3.3 mEq/L. 4. The cardiac glycoside to the client who has a digoxin level of 1.4 mg/dL.

ANS : 3 1. The thyroid hormone must be administered daily, and thyroid levels are drawn every six (6) months or so. 2. A blood glucose level of 210 mg/dL requires insulin administration; therefore, the nurse should not question administering this medication 3. This potassium level is below normal, which is 3.5 to 5.5 mEq/L. Therefore, the nurse should question administering this medication because loop diuretics cause potassium loss in the urine. 4. The digoxin level is within therapeutic range—0.8 to 2.0 mg/dL; therefore, the nurse should administer this medication

The nurse is planning the care of a client diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH). Which interventions should be implemented? Select all that apply. 1. Restrict fluids per health-care provider order. 2. Assess level of consciousness every two (2) hours. 3. Provide an atmosphere of stimulation. 4. Monitor urine and serum osmolality. 5. Weigh the client every three (3) day

ANS: 1, 2, 4 1. Fluids are restricted to 500 to 600 mL per 24 hours. 2. Orientation to person, place, and time should be assessed every two (2) hours or more often. 3. A safe environment, not a stimulating one, is provided. 4. Urine and serum osmolality are monitored to determine fluid volume status. 5. The client should be weighed daily.

The nurse is admitting a client diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH). Which clinical manifestations should be reported to the health-care provider? 1. Serum sodium of 112 mEq/L and a headache. 2. Serum potassium of 5.0 mEq/L and a heightened awareness. 3. Serum calcium of 10 mg/dL and tented tissue turgor. 4. Serum magnesium of 1.2 mg/dL and large urinary output.

ANS: 1. A serum sodium level of 112 mEq/L is dangerously low, and the client is at risk for seizures. A headache is a symptom of a low sodium level. 2. This is a normal potassium level, and a heightened level of awareness indicates drug usage. 3. This is a normal calcium level and the client is fluid overloaded, not dehydrated, so there would not be tented tissue turgor. 4. This is a normal magnesium level, and a large urinary output is desired.

Which laboratory value should be monitored by the nurse for the client diagnosed with diabetes insipidus? 1. Serum sodium. 2. Serum calcium 3. Urine glucose. 4. Urine white blood cells.

ANS: 1. The client will have an elevated sodium level as a result of low circulating blood volume. The fluid is being lost through the urine. Diabetes means "to pass through" in Greek, indicating polyuria, a symptom shared with diabetes mellitus. Diabetes insipidus is a totally separate disease process. 2. Serum calcium is not affected by diabetes insipidus. 3. Urine glucose is monitored for diabetes mellitus. 4. White blood cells in the urine indicate the presence of a urinary tract infection.

The client diagnosed with a pituitary tumor developed syndrome of inappropriate antidiuretic hormone (SIADH). Which interventions should the nurse implement? 1. Assess for dehydration and monitor blood glucose levels. 2. Assess for nausea and vomiting and weigh daily. 3. Monitor potassium levels and encourage fluid intake. 4. Administer vasopressin IV and conduct a fluid deprivation test.

ANS: 2. Early signs and symptoms are nausea and vomiting. The client has the syndrome of inappropriate secretion of antidiuretic (against allowing the body to urinate) hormone. In other words, the client is producing a hormone that will not allow the client to urinate. 1. The client has excess fluid and is not dehydrated, and blood glucose levels are not affected. 3. The client experiences dilutional hyponatremia, and the body has too much fluid already. 4. Vasopressin is the name of the antidiuretic hormone. Giving more increases the client's problem. Also, a water challenge test is performed, not a fluid deprivation test.

The nurse is discharging a client diagnosed with diabetes insipidus. Which statement made by the client warrants further intervention? 1. "I will keep a list of my medications in my wallet and wear a Medic Alert bracelet." 2. "I should take my medication in the morning and leave it refrigerated at home." 3. "I should weigh myself every morning and record any weight gain." 4. "If I develop a tightness in my chest, I will call my health-care provider."

ANS: 2. Medication for DI is usually taken every 8 to 12 hours, depending on the client. The client should keep the medication close at hand. 1. The client should keep a list of medication being taken and wear a Medic Alert bracelet. 3. The client is at risk for fluid shifts. Weighing every morning allows the client to follow the fluid shifts. Weight gain indicates too much medication. 4. Tightness in the chest could be an indicator the medication is not being tolerated; if this occurs, the client should notify the health-care provider.

The nurse is admitting a client to the neurological intensive care unit who is postoperative transsphenoidal hypophysectomy. Which data warrant immediate intervention? 1. The client is alert to name but is unable to tell the nurse the location. 2. The client has an output of 2,500 mL since surgery and an intake of 1,000 mL. 3. The client's vital signs are T 97.6ºF, P 88, R 20, and BP 130/80. 4. The client has a 3-cm amount of dark-red drainage on the turban dressing.

ANS: 2. The output is more than double the intake in a short time. This client could be developing diabetes insipidus, a complication of trauma to the head. 1. Neurological status is monitored every one (1) to two (2) hours. This client's neurological status appears intact. Clients waking up in an intensive care area may not be aware of their surroundings. 3. These vital signs are within normal limits. 4. A transsphenoidal hypophysectomy is performed by surgical access above the gum line and through the nasal passage. There is no dressing. A drip pad is taped below the nares.

The male client diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH) secondary to cancer of the lung tells the nurse he wants to discontinue the fluid restriction and does not care if he dies. Which action by the nurse is an example of the ethical principle of autonomy? 1. Discuss the information the client told the nurse with the health-care provider and significant other. 2. Explain it is possible the client could have a seizure if he drank fluid beyond the restrictions. 3. Notify the health-care provider of the client's wishes and give the client fluids as desired. 4. Allow the client an extra drink of water and explain the nurse could get into trouble if the client tells the health-care provider.

ANS: 3. This is an example of autonomy (the client has the right to decide for himself). 1. Discussing the information with others is not allowing the client to decide what is best for himself. 2. This could be an example of beneficence (to do good) if the nurse did this so the client has information on which to base a decision on whether to continue the fluid restriction. 4. This is an example of dishonesty and should never be tolerated in a health-care setting.

The nurse is caring for a client diagnosed with diabetes insipidus (DI). Which intervention should be implemented? 1. Administer sliding-scale insulin as ordered. 2. Restrict caffeinated beverages. 3. Check urine ketones if blood glucose is >250. 4. Assess tissue turgor every four (4) hours.

ANS: 4. The client is excreting large amounts of dilute urine. If the client is unable to drink enough fluids, the client will quickly become dehydrated, so tissue turgor should be assessed frequently. 1. Diabetes insipidus is not diabetes mellitus; sliding-scale insulin is not administered to the client. 2. There is no caffeine restriction for DI. 3. Checking urine ketones is not indicated.

The nurse is caring for clients on a medical floor. Which client should be assessed first? 1. The client diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH) who has a weight gain of 1.5 pounds since yesterday. 2. The client diagnosed with a pituitary tumor who has developed diabetes insipidus (DI) and has an intake of 1,500 mL and an output of 1,600 mL in the last 8 hours. 3. The client diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH) who is having muscle twitching. 4. The client diagnosed with diabetes insipidus (DI) who is complaining of feeling tired after having to get up at night.

ANS:. 3. Muscle twitching is a sign of early sodium imbalance. If an immediate intervention is not made, the client could begin to seize. 1. Clients with SIADH have a problem with retaining fluid. This is expected. 2. This client's intake and output are relatively the same 4. The client has to get up all night to urinate, so the client feeling tired is expected.

The nurse is planning the care of a client diagnosed with Addison's disease. Which intervention should be included? 1. Administer steroid medications. 2. Place the client on fluid restriction. 3. Provide frequent stimulation. 4. Consult physical therapy for gait training.

1. Clients diagnosed with Addison's disease have adrenal gland hypofunction. The hormones normally produced by the gland must be replaced. Steroids and androgens are produced by the adrenal gland.

The nurse is performing discharge teaching for a client diagnosed with Cushing's disease. Which statement by the client demonstrates an understanding of the instructions? 1. "I will be sure to notify my health-care provider if I start to run a fever." 2. "Before I stop taking the prednisone, I will be taught how to taper it off." 3. "If I get weak and shaky, I need to eat some hard candy or drink some juice." 4. "It is fine if I continue to participate in weekend games of tackle football."

1. Cushing's syndrome/disease predisposes the client to develop infections as a result of the immunosuppressive nature of the disease

"I will be sure to notify my health-care provider if I start to run a fever." 2. "Before I stop taking the prednisone, I will be taught how to taper it off." 3. "If I get weak and shaky, I need to eat some hard candy or drink some juice." 4. "It is fine if I continue to participate in weekend games of tackle football."

1. Cushing's syndrome/disease predisposes the client to develop infections as a result of the immunosuppressive nature of the disease.

The 68-year-old client diagnosed with hyperthyroidism is being treated with radioactive iodine therapy. Which interventions should the nurse discuss with the client? 1. Explain it will take up to a month for symptoms of hyperthyroidism to subside. 2. Teach the iodine therapy will have to be tapered slowly over one (1) week. 3. Discuss the client will have to be hospitalized during the radioactive therapy. 4. Inform the client after therapy the client will not have to take any medication

1. Radioactive iodine therapy is used to destroy the overactive thyroid cells. After treatment, the client is followed closely for three (3) to four (4) weeks until the euthyroid state is reached

The client diagnosed with Addison's disease is admitted to the emergency department after a day at the lake. The client is lethargic, forgetful, and weak. Which intervention should the nurse implement? 1. Start an IV with an 18-gauge needle and infuse NS rapidly. 2. Have the client wait in the waiting room until a bed is available. 3. Obtain a permit for the client to receive a blood transfusion. 4. Collect urinalysis and blood samples for a CBC and calcium level.

1. The client was exposed to wind and sun at the lake during the hours prior to being admitted to the emergency depart- ment. This predisposes the client to dehydration and an addisonian crisis. Rapid IV fluid replacement is necessary.

The client has developed iatrogenic Cushing's disease. Which statement is the scientific rationale for the development of this diagnosis? 1. The client has an autoimmune problem causing the destruction of the adrenal cortex. 2. The client has been taking steroid medications for an extended period for another disease process. 3. The client has a pituitary gland tumor causing the adrenal glands to produce too much cortisol. 4. The client has developed an adrenal gland problem for which the health-care provider does not have an explanation.

2. "Iatrogenic" means a problem has been caused by a medical treatment or procedure—in this case, treatment with steroids for another problem. Clients taking steroids over a period of time develop the clinical manifestations of Cushing's disease. Disease processes for which long-term steroids are prescribed include chronic obstructive pulmonary disease, cancer, and arthritis.

The client is admitted to rule out Cushing's syndrome. Which laboratory tests should the nurse anticipate being ordered? 1. Plasma drug levels of quinidine, digoxin, and hydralazine. 2. Plasma levels of ACTH and cortisol. 3. A 24-hour urine for metanephrine and catecholamine. 4. Spot urine for creatinine and white blood cells (WBCs).

2. The adrenal gland secretes cortisol and the pituitary gland secretes adrenocorti- cotropic hormone (ACTH), a hormone used by the body to stimulate the produc- tion of cortisol.

2."Iatrogenic" means a problem has been caused by a medical treatment or procedure—in this case, treatment with steroids for another problem. Clients taking steroids over a period of time develop the clinical manifestations of Cushing's disease. Disease processes for which long-term steroids are prescribed include chronic obstructive pulmonary disease, cancer, and arthritis.

The nurse is admitting a client diagnosed with primary adrenal cortex insufficiency (Addison's disease). Which clinical manifestations should the nurse expect to assess? 1. Moon face, buffalo hump, and hyperglycemia. 2. Hirsutism, fever, and irritability. 3. Bronze pigmentation, hypotension, and anorexia. 4. Tachycardia, bulging eyes, and goiter.

3. Bronze pigmentation of the skin, particu- larly of the knuckles and other areas of skin creases, occurs in Addison's disease. Hypotension and anorexia also occur with Addison's disease.

The client diagnosed with Cushing's disease has undergone a unilateral adrenalectomy. Which discharge instructions should the nurse discuss with the client? 1. Instruct the client to take the glucocorticoid and mineralocorticoid medications as prescribed. 2. Teach the client regarding sexual functioning and androgen replacement therapy. 3. Explain the signs and symptoms of infection and when to call the health-care provider. 4. Demonstrate turn, cough, and deep-breathing exercises the client should perform every (2) hours.

3. Notifying the HCP if signs/symptoms of infection develop is an instruction given to all surgical clients on discharge.

The client diagnosed with hypothyroidism is prescribed the thyroid hormone levothyroxine (Synthroid). Which assessment data indicate the medication has been effective? 1. The client has a three (3)-pound weight gain. 2. The client has a decreased pulse rate. 3. The client's temperature is WNL. 4. The client denies any diaphoresis.

3. The client with hypothyroidism frequently has a subnormal temperature, so a temperature WNL indicates the medication is effective.

The charge nurse of an intensive care unit is making assignments for the night shift. Which client should be assigned to the most experienced intensive care nurse? 1. The client diagnosed with respiratory failure who is on a ventilator and requires frequent sedation. 2. The client diagnosed with lung cancer and iatrogenic Cushing's disease with ABGs of pH 7.35, Pao2 88, Paco2 44, and HCO3 22. 3. The client diagnosed with Addison's disease who is lethargic and has a BP of 80/45, P 124, and R 28. 4. The client diagnosed with hyperthyroidism who has undergone a thyroidectomy two (2) days ago and has a negative Trousseau's sign.

3. This client has a low blood pressure and tachycardia. This client may be experi- encing an addisonian crisis, a potentially life-threatening condition. The most expe- rienced nurse should care for this client.

Which statement made by the client makes the nurse suspect the client is experiencing hyperthyroidism? 1. "I just don't seem to have any appetite anymore." 2. "I have a bowel movement about every 3 to 4 days." 3. "My skin is really becoming dry and coarse." 4. "I have noticed all my collars are getting tighter."

4. The thyroid gland (in the neck) enlarges as a result of the increased need for thyroid hormone production; an enlarged gland is called a goiter.

The nurse is teaching the client diagnosed with hyperthyroidism. Which information should be taught to the client? Select all that apply. 1. Notify the HCP if a three (3)-pound weight loss occurs in two (2) days. 2. Discuss ways to cope with the emotional lability. 3. Notify the HCP if taking over-the-counter medication. 4. Carry a medical identification card or bracelet. 5. Teach how to take thyroid medications correctly

ANS : 1,2,3,4 1. Weight loss indicates the medication may not be effective and will probably need to be increased. 2. The client needs to know emotional highs and lows are secondary to hyperthyroidism. With treatment, this emotional lability will subside. 3. Any over-the-counter medications (for example, alcohol-based medications) may negatively affect the client's hyperthyroidism or medications being used for treatment. 4. This will help any HCP immediately know of the client's condition, especially if the client is unable to tell the HCP. 5. The client with hyperthyroidism will be on antithyroid medications, not thyroid medications.

The client is diagnosed with hypothyroidism. Which signs/symptoms should the nurse expect the client to exhibit? 1. Complaints of extreme fatigue and hair loss. 2. Exophthalmos and complaints of nervousness. 3. Complaints of profuse sweating and flushed skin. 4. Tetany and complaints of stiffness of the hands.

ANS : 1 1. A decrease in thyroid hormone causes decreased metabolism, which leads to fatigue and hair loss. 2. These are signs of hyperthyroidism. 3. These are signs of hyperthyroidism. 4. These are signs of parathyroidism

The client is admitted to the medical unit with a diagnosis of rule-out diabetes insipidus (DI). Which instructions should the nurse teach regarding a fluid deprivation test? 1. The client will be asked to drink 100 mL of fluid as rapidly as possible and then will not be allowed fluid for 24 hours. 2. The client will be administered an injection of antidiuretic hormone, and urine output will be measured for four (4) to six (6) hours. 3. The client will be NPO, and vital signs and weights will be done hourly until the end of the test. 4. An IV will be started with normal saline, and the client will be asked to try to hold the urine in the bladder until a sonogram can be done.

ANS: 3. The client is deprived of all fluids, and if the client has DI the urine production will not diminish. Vital signs and weights are taken every hour to determine circulatory status. If a marked decrease in weight or vital signs occurs, the test is immediately terminated. 1. The client is not allowed to drink during the test. 2. This test does not require any medications to be administered, and vasopressin will treat the DI, not help diagnose it. 4. No fluid is allowed and a sonogram is not involved.

The unlicensed assistive personnel (UAP) complains to the nurse she has filled the water pitcher four (4) times during the shift for a client diagnosed with a closed head injury and the client has asked for the pitcher to be filled again. Which intervention should the nurse implement first? 1. Tell the UAP to fill the pitcher with ice cold water. 2. Instruct the UAP to start measuring the client's I & O. 3. Assess the client for polyuria and polydipsia. 4. Check the client's BUN and creatinine levels.

ANS: 3. The first action should be to determine if the client is experiencing polyuria and polydipsia as a result of developing diabetes insipidus, a complication of the head trauma. 1. The client should have the water pitcher filled, but this is not the first action. 2. This should be done but not before assessing the problem. 4. This could be done, but it will not give the nurse information about DI.

The nurse identifies the client problem "risk for imbalanced body temperature" for the client diagnosed with hypothyroidism. Which intervention should be included in the plan of care? 1. Discourage the use of an electric blanket. 2. Assess the client's temperature every two (2) hours. 3. Keep the room temperature cool. 4. Space activities to promote rest.

ANs 1 1. External heat sources (heating pads, electric or warming blankets) should be discouraged because they increase the risk of peripheral vasodilation and vascular collapse 2. Assessing the client's temperature every two (2) hours is not needed because the temperature will not change quickly. The client needs thyroid hormones to help increase the client's temperature. 3. The room temperature should be kept warm because the client will have complaints of being cold. 4. The client is fatigued and this is an appropriate intervention, but is not applicable to the client problem of "risk for imbalanced body temperature."

Which nursing intervention should be included in the plan of care for the client diagnosed with hyperthyroidism? 1. Increase the amount of fiber in the diet. 2. Encourage a low-calorie, low-protein diet. 3. Decrease the client's fluid intake to 1,000 mL/day. 4. Provide six (6) small, well-balanced meals a day.

ANs : 4 1. Fiber should be increased in the client diagnosed with hypothyroidism because the client experiences constipation secondary to decreased metabolism. 2. The client with hyperthyroidism should have a high-calorie, high-protein diet. 3. The client's fluid intake should be increased to replace fluids lost through diarrhea and excessive sweating. 4. The client with hyperthyroidism has an increased appetite; therefore, wellbalanced meals served several times throughout the day will help with the client's constant hunger.

The client is admitted to the intensive care department diagnosed with myxedema coma. Which assessment data warrant immediate intervention by the nurse? 1. Serum blood glucose level of 74 mg/dL. 2. Pulse oximeter reading of 90%. 3. Telemetry reading showing sinus bradycardia. 4. The client is lethargic and sleeps all the time.

Ans : 2 A pulse oximeter reading of less than 93% is significant. A 90% pulse oximeter reading indicates a PaO2 of approximately 60 on an arterial blood gas test; this is severe hypoxemia and requires immediate intervention. 3. The client with myxedema coma is in an exaggerated hypothyroid state; a low pulse is expected in a client with hypothyroidism. 4. Lethargy is an expected symptom in a client diagnosed with myxedema; therefore, this does not warrant immediate intervention.

A patient is admitted to the hospital with a diagnosis of Cushing syndrome. On physical assessment of the patient, what should the nurse expect to find? a. Hypertension, peripheral edema, and petechiae b. Weight loss, buffalo hump, and moon face with acne c. Abdominal and buttock striae, truncal obesity, and hypotension d. Anorexia, signs of dehydration, and hyperpigmentation of the skin

a. The effects of adrenocortical hormone excess, especially glucocorticoid excess, include weight gain from accumulation and redistribution of adipose tissue, sodium and water retention, glucose intolerance, protein wasting,loss of bone structure, loss of collagen, and capillary fragility leading to petechiae. Clinical manifestations of adrenocortical hormone deficiency include hypotension, dehydration, weight loss, and hyperpigmentation of the skin.

During care of the patient with SIADH, what should the nurse do? a. Monitor neurologic status at least every 2 hours. b. Teach the patient receiving treatment with diuretics to restrict sodium intake. c. Keep the head of the bed elevated to prevent antidiuretic hormone (ADH) release. d. Notify the health care provider if the patient's blood pressure decreases more than 20 mm Hg from baseline.

a. The patient with syndrome of inappropriate antidiuretic hormone (SIADH) has marked dilutional hyponatremia and should be monitored for decreased neurologic function and seizures every 2 hours. Sodium intake is supplemented because of the hyponatremia and sodium loss caused by diuretics. ADH release is reduced by keeping the head of the bed flat to increase left atrial filling pressure. A reduction in blood pressure (BP) indicates a reduction in total fluid volume and is an expected outcome of treatment.

What preoperative instruction should the nurse give to the patient scheduled for a subtotal thyroidectomy? a. How to support the head with the hands when turning in bed b. Coughing should be avoided to prevent pressure on the incision c. Head and neck will need to remain immobile until the incision heals d. Any tingling around the lips or in the fingers after surgery is expected and temporary

a. To prevent strain on the suture line postoperatively, the patient's head must be manually supported while turning and moving in bed but range-of-motion exercises for the head and neck are also taught preoperatively to be gradually implemented after surgery. There is no contraindication for coughing and deep breathing and these should be carried out postoperatively. Tingling around the lips or fingers is a sign of hypocalcemia, which may occur if the parathyroid glands are inadvertently removed during surgery. This sign should be reported immediately.

During discharge teaching for the patient with Addison's disease, which statement by the patient indicates that the nurse needs to do additional teaching? a. "I should always call the doctor if I develop vomiting or diarrhea." b. "If my weight goes down, my dosage of steroid is probably too high." c. "I should double or triple my steroid dose if I undergo rigorous physical exercise." d. "I need to carry an emergency kit with injectable hydrocortisone in case I can't take my medication by mouth."

b. A weight reduction in the patient with Addison's disease may indicate a fluid loss and a dose of replacement therapy that is too low rather than too high. Because vomiting and diarrhea are early signs of crisis and because fluid and electrolytes must be replaced, patients should notify their health care provider if these symptoms occur. Patients with Addison's disease are taught to take two to three times their usual dose of steroids if they become ill, have teeth extracted, or engage in rigorous physical activity and should always have injectablehydrocortisone available if oral doses cannot be taken.

The nurse has identified the nursing diagnosis of fatigue for a patient who is hypothyroid. What should the nurse do while caring for this patient? a. Monitor for changes in orientation, cognition, and behavior. b. Monitor for vital signs and cardiac rhythm response to activity. c. Monitor bowel movement frequency, consistency, shape, volume, and color. d. Assist in developing well-balanced meal plans consistent with level of energy expenditure.

b. Cardiorespiratory response to activity is important to monitor in this patient to determine the effect of activities and plan activity increases. Monitoring changes in orientation, cognition, and behavior are interventions for impaired memory. Monitoring bowels is needed to plan care for the patient with constipation. Assisting with meal planning will help the patient with imbalanced nutrition: more than body requirements to lose weight if needed.

A patient with SIADH is treated with water restriction. What does the patient experience when the nurse determines that treatment has been effective? a. Increased urine output, decreased serum sodium, and increased urine specific gravity b. Increased urine output, increased serum sodium, and decreased urine specific gravity c. Decreased urine output, increased serum sodium, and decreased urine specific gravity d. Decreased urine output, decreased serum sodium, and increased urine specific gravity

b. The patient with SIADH has water retention with hyponatremia, decreased urine output, and concentrated urine with high specific gravity. Improvement in the patient's condition is reflected by increased urine output, normalization of serum sodium, and more water in the urine, thus decreasing the specific gravity.

A patient with Addison's disease comes to the emergency department with complaints of nausea, vomiting, diarrhea, and fever. What collaborative care should the nurse expect? a. IV administration of vasopressors b. IV administration of hydrocortisone c. IV administration of D5W with 20 mEq KCl d. Parenteral injections of adrenocorticotropic hormone (ACTH)

b. Vomiting and diarrhea are early indicators of Addisonian crisis and fever indicates an infection, which is causing additional stress for the patient. Treatment of a crisis requires immediate glucocorticoid replacement and IV hydrocortisone, fluids, sodium, and glucose are necessary for 24 hours. Addison's disease is a primary insufficiency of the adrenal gland and adrenocorticotropic hormone (ACTH) is not effective, nor would vasopressors be effective with the fluid deficiency of Addison's disease. Potassium levels are increased in Addison's disease and KCl would be contraindicated.

The patient is diagnosed with syndrome of inappropriate antidiuretic hormone (SIADH). What manifestation should the nurse expect to find? a. Decreased body weight b. Decreased urinary output c. Increased plasma osmolality d. Increased serum sodium levels

b. With increased antidiuretic hormone (ADH), the permeability of the renal distal tubules is increased, so water is reabsorbed into circulation. Decreased output of concentrated urine with increased urine osmolality and specific gravity occur. In addition, fluid retention with weight gain, serum hypoosmolality, dilutional hyponatremia, and hypochloremia occur.

A patient is admitted to the hospital with thyrotoxicosis. On physical assessment of the patient, what should the nurse expect to find? a. Hoarseness and laryngeal stridor b. Bulging eyeballs and dysrhythmias c. Elevated temperature and signs of heart failure d. Lethargy progressing suddenly to impairment of consciousness

c. A hyperthyroid crisis results in marked manifestations of hyperthyroidism, with severe tachycardia, heart failure, shock, hyperthermia, restlessness, irritability, abdominal pain, vomiting, diarrhea, delirium, and coma. Although exophthalmos may be present in the patient with Graves' disease, it is not a significant factor in hyperthyroid crisis. Hoarseness and laryngeal stridor are characteristic of the tetany of hypoparathyroidism and lethargy progressing to coma is characteristic of myxedema coma, a complication of hypothyroidism.

A patient is scheduled for a bilateral adrenalectomy. During the postoperative period, what should the nurse expect related to the administration of corticosteroids? a. Reduced to promote wound healing b. Withheld until symptoms of hypocortisolism appear c. Increased to promote an adequate response to the stress of surgery d. Reduced because excessive hormones are released during surgical manipulation of adrenal glands

c. Although the patient with Cushing syndrome has excess corticosteroids, removal of the glands and the stress of surgery require that high doses of corticosteroids (cortisone) be administered postoperatively for several days before weaning the dose. The nurse should monitor the patient's vital signs postoperatively to detect whether large amounts of hormones were released during surgical manipulation, obtain morning urine specimens for cortisol measurement to evaluate the effectiveness of the surgery, and provide dressing changes with aseptic technique to avoid infection as usual inflammatory responses are suppressed.

A patient with diabetes insipidus is treated with nasal desmopressin acetate (DDAVP). The nurse determines that the drug is not having an adequate therapeutic effect when the patient experiences a. headache and weight gain. b. nasal irritation and nausea. c. a urine specific gravity of 1.002. d. an oral intake greater than urinary output.

c. Normal urine specific gravity is 1.005 to 1.025 and urine with a specific gravity of 1.002 is very dilute, indicating that there continues to be excessive loss of water and that treatment of diabetes insipidus is inadequate. Headache, weight gain, and oral intake greater than urinary output are signs of volume excess that occur with overmedication. Nasal irritation and nausea may also indicate overdosage.

The patient with diabetes insipidus is brought to the emergency department with confusion and dehydration after excretion of a large volume of urine today even though several liters of fluid were drunk. What is a diagnostic test that the nurse should expect to be done to help make a diagnosis? a. Blood glucose b. Serum sodium level c. Urine specific gravity d. Computed tomography (CT) of the head

c. Patients with diabetes insipidus (DI) excrete large amounts of urine with a specific gravity of less than 1.005. Blood glucose would be tested to diagnose diabetes mellitus. The serum sodium level is expected to be low with DI but is not diagnostic. To diagnose central DI a water deprivation test is required. Then a CT of the head may be done to determine the cause. Nephrogenic DI is differentiated from central DI with determination of the level of ADH after an analog of ADH is given.

In a patient with central diabetes insipidus, what will the administration of ADH during a water deprivation test result in? a. Decrease in body weight b. Increase in urinary output c. Decrease in blood pressure d. Increase in urine osmolality

d. A patient with central diabetes insipidus has a deficiency of ADH with excessive loss of water from the kidney, hypovolemia, hypernatremia, and dilute urine with a low specific gravity. When vasopressin is administered, the symptoms are reversed, with water retention, decreased urinary output that increases urine osmolality, and an increase in BP.

Priority Decision: When replacement therapy is started for a patient with long-standing hypothyroidism, what is most important for the nurse to monitor the patient for? a. Insomnia b. Weight loss c. Nervousness d. Dysrhythmias

d. All these manifestations may occur with treatment of hypothyroidism. However, as a result of the effects of hypothyroidism on the cardiovascular system, when thyroid replacement therapy is started myocardial oxygen consumption is increased and the resultant oxygen demand may cause angina, cardiac dysrhythmias, and heart failure, so monitoring for dysrhythmias is most important.

When providing discharge instructions to a patient who had a subtotal thyroidectomy for hyperthyroidism, what should the nurse teach the patient? a. Never miss a daily dose of thyroid replacement therapy. b. Avoid regular exercise until thyroid function is normalized. c. Use warm saltwater gargles several times a day to relieve throat pain. d. Substantially reduce caloric intake compared to what was eaten before surgery.

d. With the decrease in thyroid hormone postoperatively, calories need to be reduced substantially to prevent weight gain. When a patient has had a subtotal thyroidectomy, thyroid replacement therapy is not given because exogenous hormone inhibits pituitary production of TSH and delays or prevents the restoration of thyroid tissue regeneration. Regular exercise stimulates the thyroid gland and is encouraged. Saltwater gargles are used for dryness and irritation of the mouth and throat following radioactive iodine therapy.
