A nurse is following the progress of a client being treated for
hypothyroidism. Which findings indicate that thyroid
replacement therapy has been inadequate? Select all that
apply.
a) Tachycardia.
b) Bradycardia.
c) Nervousness.
d) Dry mouth.
e) Prolonged QT interval on ECG.
f) Low body temperature. - ANSWERS-• Prolonged QT
interval on ECG.
• Low body temperature.
,• Bradycardia.
Explanation:
In hypothyroidism, the body is in a hypometabolic state.
Therefore, a prolonged QT interval with bradycardia and
subnormal body temperature would indicate that
replacement therapy was inadequate.
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) Hypermagnesemia
b) Hyponatremia
c) Hypocalcemia
d) Hyperkalemia - ANSWERS-Hypocalcemia
Explanation:
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
,For a client with hyperthyroidism, treatment is most likely
to include:
a) a thyroid hormone antagonist.
b) thyroid extract.
c) emollient lotions.
d) a synthetic thyroid hormone. - ANSWERS-a thyroid
hormone antagonist.
Explanation:
Thyroid hormone antagonists, which block thyroid hormone
synthesis, combat increased production of thyroid hormone.
Treatment of hyperthyroidism also may include radioiodine
therapy, which destroys some thyroid gland cells, and
surgery to remove part of the thyroid gland; both
treatments decrease thyroid hormone production.
A client with Cushing's syndrome is admitted to the medical-
surgical unit. During the admission assessment, the nurse
notes that the client is agitated and irritable, has poor
memory, reports loss of appetite, and appears disheveled.
These findings are consistent with:
, a) hyperthyroidism.
b) neuropathy.
c) depression.
d) hypoglycemia. - ANSWERS-depression.
Explanation:
Agitation, irritability, poor memory, loss of appetite, and
neglect of one's appearance may signal depression, which is
common in clients with Cushing's syndrome.
A physician orders an isotonic I.V. solution for a client.
Which solution should the nurse plan to administer?
a) Half-normal saline solution
b) 10% dextrose in water
c) 5% dextrose and normal saline solution
d) Lactated Ringer's solution - ANSWERS-Lactated Ringer's
solution
Explanation:
Lactated Ringer's solution, with an osmolality of
approximately 273 mOsm/L, is isotonic.
