MCA II EXAM 3 QUESTIONS & ANSWERS
SOLVED 100% CORRECT!!
Which type of hepatitis develops into a chronic form of the disease? select all that apply.
- hepatitis A
- hepatitis B
- hepatitis C
- hepatitis D
- hepatitis E Answer - B, C, D
- Elevated serum calcium
- Sudden drop in pulse rate
- Hypothermia and dry skin
- Rapid heartbeat and tremors Answer - d. Rapid heartbeat and tremors
Hepatitis B and C generally develop into chronic hepatitis. Hepatitis D is an incomplete virus that can become chronic and is dependent on the presence of hepatitis B to survive. Hepatitis A and E are acute, self-limiting infections that resolve over time and do not develop with chronic hepatitis.A nurse is providing postoperative care for a client who has begun taking levothyroxine after undergoing a thyroidectomy. Which findings in the client may indicate potential thyrotoxic crisis?
Thyrotoxic crisis (thyroid storm) refers to a sudden and excessive release of thyroid hormones, which causes pyrexia, tachycardia, and exaggerated symptoms of thyrotoxicosis; surgery, infection, and ablation therapy can 1 / 4
precipitate this life-threatening condition. Hypercalcemia is not related to thyrotoxic crisis; hypocalcemia results from accidental removal of the parathyroid glands. Tachycardia is an increased, not decreased, heart rate, which occurs with thyrotoxic crisis because of the sudden release of thyroid hormones; thyroid hormones increase the basal metabolic rate. Fever, not hypothermia, and diaphoresis, not dry skin, occur with thyrotoxic crisis because of the sudden release of thyroid hormones, which increase the basal metabolic rate.h Which questions would the nurse ask when assessing a client diagnosed with acromegaly? select all that apply.
- "have you noticed any changes to your vision?"
- "have you ever been told that you snore loudly?"
- "have you had any changes in your menstrual cycle?"
- "have you noticed any chances to your bowel movements?"
- "have you noted you consume excess amount of cruciferous vegetables?"
Answer - A, B, D It is reasonable to ask a client with acromegaly if he or she has experienced changes in his or her vision, because pressure on the optic nerve from a pituitary adenoma can occur. some clients with acromegaly will develop sleep apnea, secondary to upper airway narrowing and obstruction from increased amounts of pharyngeal soft tissues. clients with acromegaly are at an increased risk of colorectal cancer. it is not necessary to ask the client with acromegaly about her menstrual cycle; acromegaly is the overgrowth of soft tissue and bone in the hands, feet, and face, and does not affect the reproductive organs as some other excesses of tropic hormones do. intake of cruciferous vegetables will not affect acromegaly; the goitrogens in these vegetables contain thyroid- inhibiting substance and can lead to goiter if eaten in excessive amounts.The nurse is admitting a client with severe myxedema coma. Which interventions would the nurse include in the plan of care? Select all that apply.One, some, or all responses may be correct. 2 / 4
- Administer intravenous (IV) levothyroxine.
- Avoid use of corticosteroids.
- Give IV normal saline.
- Wait for laboratory results before treating.
- Monitor blood pressure every 4 hours. Answer - A, C
- edema
- polyuria
- bradycardia
- muscle cramps
- hyponatremia Answer - D, E
myxedema coma is a major complication of poorly treated hypothyroidism.interventions include administering IV levothyroxine. this promotes the return of normal thyroid hormone levels. IV normal saline corrects dehydration.corticosteriods are administered as part of the treatment. levothyroxine is initiated before obtaining laboratory results because waiting can cause death.the blood pressure should be monitored hourly.which clinical findings correspond with the secretion of antidiuretic hormone (ADH)? select all that apply.
muscle cramps occur when sodium level is less than 124 mEq/L and are caused by osmotic fluid shift. ADH causes water retention, which dilutes serum electrolytes such as sodium, with a resultant hyponatremia. edema is not usually seen in syndrome of inappropriate ADH (SIADH) because water retention is not extracellular.. a decreased urine output occurs with SIADH because ADH causes reabsorption of fluid in the kidney glomeruli. the increased fluid volume associated with SIADH results in tachycardia, tachypnea and crackles. 3 / 4
A client with cirrhosis of the liver has a prolonged prothrombin time and a low platelet count. A regular diet is prescribed. What should the nurse instruct the client to do considering the client's condition?
- Avoid foods high in phytonadione
- Check the pulse several times a day.
- Drink a glass of milk when taking aspirin.
- Report signs of bleeding no matter how slight. Answer - d. Report signs of
- Radioactive iodine uptake
- computed tomography scan
- magnetic resonance imaging
- thyroid-stimulating hormone Answer - a. Radioactive iodine uptake
- / 4
bleeding no matter how slight.One of the many functions of the liver is the manufacture of clotting factors; there is interference in this process with cirrhosis of the liver, resulting in bleeding tendencies. The storage of fat-soluble vitamins (A, D, E, and K), water- soluble vitamins (B1, B2, folic acid, and cobalamin), and minerals (including iron) is compromised in cirrhosis; therefore, these nutrients, including phytonadione, should not be limited. Should the client bleed, the pulse rate may be increased, but it is not necessary for the client to check the pulse rate several times daily. A client whose prothrombin time is prolonged and platelet count is low should not be taking aspirin, even with milk.While assessing a postpartum client who is suspected of having a thyroid disorder, the nurse suspects that the client has autoimmune thyroiditis. Which diagnostic studies are most suitable for confirming the diagnosis?
the postpartum client may have silent, painless thyroiditis. radioactive iodine uptake is suppressed in silent thyroiditis, so this test would be beneficial in diagnosing the thyroiditis. a computed tomography scan is used to detect thyroid nodules. magnetic resonance imaging is also used in evaluating thyroid
