What does a positive Chvostek's sign indicate? a)Hypokalemia b)Hypermagnesemia c) Hyponatremia d) hypocalcemia

A client is experiencing an increase in blood glucose levels. The nurse understands that which of the following hormones would be important in lowering the client's blood glucose level? a)Insulin b)Melatonin c)Calcitonin d)Parathormone
a
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? a)The functioning of endocrine glands b)Details about the size of the organ and its location c)The concentration of a substance in plasma d)The client's blood sugar level

On the third day after a partial thyroidectomy, a client exhibits muscle twitching and hyperirritability of the nervous system. When questioned, the client reports numbness and tingling of the mouth and fingertips. Suspecting a life-threatening electrolyte disturbance, the nurse notifies the surgeon immediately. Which electrolyte disturbance most commonly follows thyroid surgery? a)Hypocalcemia b) Hyperkalemia c)Hypermagnesemia d)Hyponatremia
a Hypocalcemia may follow thyroid surgery if the parathyroid glands were removed accidentally. Signs and symptoms of hypocalcemia may be delayed for up to 7 days after surgery. Thyroid surgery doesn't directly cause serum sodium, potassium, or magnesium abnormalities. Hyponatremia may occur if the client inadvertently received too much fluid; however, this can happen to any surgical client receiving I.V. fluid therapy, not just one recovering from thyroid surgery. Hyperkalemia and hypermagnesemia usually are associated with reduced renal excretion of potassium and magnesium, not thyroid surgery.
A client has a decreased secretion of erythropoietin from the kidneys due to end-stage kidney disease. What outcome will the decrease in erythropoietin have? a)Anemia from the decrease in maturation of red blood cells b)Increase in blood sugar levels due to alteration in insulin levels c)Decrease in blood sugar levels due to alteration in insulin levels d)Development of male sex characteristics
a The kidneys secrete erythropoietin, which is a substance that promotes the maturation of red blood cells.
Which of the following agents suppress release of thyroid hormones? Select all that apply. a)Potassium iodide b)Saturated solution of potassium iodide (SSKI) c)Dexamethasone d)Methimazole e)Sodium iodide
a,b,c,e Sodium iodide, potassium iodide, dexamethasone, and SSKI suppress the release of thyroid hormones. Methimazole blocks the synthesis of thyroid hormone.
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? a)Hypothyroidism b)Acromegaly c)Deficient growth hormone b)Type 1 diabetes mellitus
b
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? a)Free T4 analysis b)Fine-needle biopsy of the thyroid gland c)Serum immunoassay for TSH d)Ultrasound of the thyroid gland
b
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? a)parathyroid disorder b)pituitary disorder c)adrenal disorder d)thyroid disorder
b
Which hormone would be responsible for increasing blood glucose levels by stimulating glycogenolysis? a)Cholecystokinin b)Glucagon c)Insulin d)Somatostatin
b
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? a)Hyperactive deep tendon reflex b)Positive Chvostek's sign c)Tetany d)Positive Trousseau's sign
b
Which assessment is done by the nurse when conducting a physical examination? a)Palpate the thyroid gland repeatedly b)Examine the shape and color of the nails c)Determine the client's ability to participate in the assessment d)Examine outstretched hands for skin breaks
b During physical examination, the nurse examines the shape and color of the nails and determines whether they are thin, thick, or brittle. The outstretched hands should be examined for tremors. Repeated palpation of the thyroid gland may have serious implications.
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? a)Hemorrhage b)Tetany c)Thyroid storm d)Laryngeal nerve damage
b 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.
Which of the following assessments should the nurse perform to determine the development of peptic ulcers when caring for a patient with Cushing's syndrome? a)Monitor bowel patterns. b)Observe the color of stool. c)Observe urine output. d)Monitor vital signs every 4 hours.
b The nurse should observe the color of each stool and test the stool for occult blood. Bowel patterns, vital signs, and urine output do not help in determining the development of peptic ulcers
For the first 72 hours after thyroidectomy surgery, a nurse should assess a client for Chvostek's sign and Trousseau's sign because they indicate: a)hypokalemia. b)hyperkalemia. c)hypercalcemia. d)hypocalcemia.
d
Which disorder results from excessive secretion of somatotropin (growth hormone)? a)Cretinism b)Adrenogenital syndrome c)Dwarfism d)Acromegaly
d
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? a)erythropoietin b)cholecystokinin c)gastrin d) renin
d 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 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 disorder should the nurse expect the physician to diagnose? a)Diabetes mellitus B)Cushing's syndrome c)Diabetes insipidus d)Goiter
d 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 this malfunction 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.
