Physical and laboratory findings reveal hypothermia. hypoventilation. respiratory acidosis. bradycardia. hypotension. and nonpitting edema of the face and pretibial area. Knowing that these findings suggest severe hypothyroidism. nurse Libby prepares to take emergency action to prevent the potential complication of:

Explanation

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.

3. Nurse Ronn is assessing a client with possible Cushing's syndrome. In a client with Cushing's syndrome. the nurse would expect to find:

Explanation

Because of changes in fat distribution. adipose tissue accumulates in the trunk. face (moonface). and dorsocervical areas (buffalo hump). Hypertension is caused by fluid retention. Skin becomes thin and bruises easily because of a loss of collagen. Muscle wasting causes muscle atrophy and thin extremities.

Submit
4. When caring for a male client with diabetes insipidus. nurse Juliet expects to administer:

Explanation

Chvostek’s sign is elicited by tapping the client’s face lightly over the facial nerve. just below the temple. If the client’s facial muscles twitch. it indicates hypocalcemia. Hyponatremia is indicated by weight loss. abdominal cramping. muscle weakness. headache. and postural hypotension. Hypokalemia causes paralytic ileus and muscle weakness. Clients with hypermagnesemia exhibit a loss of deep tendon reflexes. coma. or cardiac arrest.

Submit
5. During preoperative teaching for a female client who will undergo subtotal thyroidectomy. the nurse should include which statement?

Explanation

To prevent undue pressure on the surgical incision after subtotal thyroidectomy. the nurse should advise the client to avoid hyperextending the neck. The client may elevate the head of the bed as desired and should perform deep breathing and coughing to help prevent pneumonia. Subtotal thyroidectomy doesn’t affect swallowing.

Submit
6. A male client with primary diabetes insipidus is ready for discharge on desmopressin (DDAVP). Which instruction should nurse Lina provide?

Explanation

Desmopressin may not be absorbed if the intranasal route is compromised. Although diabetes insipidus is treatable. the client should wear medical identification and carry medication at all times to alert medical personnel in an emergency and ensure proper treatment. The client must continue to monitor fluid intake and output and receive adequate fluid replacement.

Submit
7. In a 29-year-old female client who is being successfully treated for Cushing's syndrome. nurse Lyzette would expect a decline in:

Explanation

Hyperglycemia. which develops from glucocorticoid excess. is a manifestation of Cushing’s syndrome. With successful treatment of the disorder. serum glucose levels decline. Hirsutism is common in Cushing’s syndrome; therefore. with successful treatment. abnormal hair growth also declines. Osteoporosis occurs in Cushing’s syndrome; therefore. with successful treatment. bone mineralization increases. Amenorrhea develops in Cushing’s syndrome. With successful treatment. the client experiences a return of menstrual flow. not a decline in it.

Submit
8. When caring for a female client with a history of hypoglycemia. nurse Ruby should avoid administering a drug that may potentiate hypoglycemia. Which drug fits this description?

Explanation

Sulfisoxazole and other sulfonamides are chemically related to oral antidiabetic agents and may precipitate hypoglycemia. Mexiletine. an antiarrhythmic. is used to treat refractory ventricular arrhythmias; it doesn’t cause hypoglycemia. Prednisone. a corticosteroid. is associated with hyperglycemia. Lithium may cause transient hyperglycemia. not hypoglycemia.

Submit
9. A male client has recently undergone surgical removal of a pituitary tumor. Dr. Wong prescribes corticotropin (Acthar). 20 units I.M. q.i.d. as a replacement therapy. What is the mechanism of action of corticotropin?

Explanation

Corticotropin interacts with plasma membrane receptors to produce enzymatic actions that affect protein. fat. and carbohydrate metabolism. It doesn’t decrease cAMP production. The posterior pituitary hormone. antidiuretic hormone. regulates the threshold for water resorption in the kidneys.

Submit
10. After taking glipizide (Glucotrol) for 9 months. a male client experiences secondary failure. Which of the following would the nurse expect the physician to do?

Explanation

Many clients (25% to 60%) with secondary failure respond to a different oral antidiabetic agent. Therefore. it wouldn’t be appropriate to initiate insulin therapy at this time. However. if a new oral antidiabetic agent is unsuccessful in keeping glucose levels at an acceptable level. insulin may be used in addition to the antidiabetic agent.
