A client has a decreased level of thyroid hormone being excreted. What will the feedback loop do to
maintain the level of thyroid hormone required to maintain homeostatic stability?
a) Produce a new hormone to try and regulate the thyroid function
b) The feedback loop will be unable to perform in response to low levels of thyroid hormone.
c) Stimulate more hormones using the positive feedback system
d) Stimulate more hormones using the negative feedback system - ✔ ✔ d) Stimulate more hormones
using the negative feedback system
Explanation:
Feedback can be either negative or positive. Most hormones are secreted in response to negative
feedback; a decrease in levels stimulates the releasing gland.
A client has a dysfunction in one of his glands that is causing a decrease in the level of calcium in the
blood. What gland should be evaluated for dysfunction?
a) Thyroid gland
b) Thymus gland
c) Parathyroid gland
d) Adrenal gland - ✔ ✔ c) Parathyroid gland
Explanation:
,The parathyroids secrete parathormone, which increases the level of calcium in the blood when there is
a decrease in the serum level. The thyroid, thymus, and adrenal gland do not secrete calcium.
A client is admitted for treatment of the syndrome of inappropriate antidiuretic hormone (SIADH).
Which nursing intervention is appropriate?
a) Administering glucose-containing I.V. fluids as ordered
To reduce water retention in a client with the SIADH, the nurse should restrict fluids. Administering
fluids by any route would further increase the client's already heightened fluid load.
A client is admitted to an acute care facility with a tentative diagnosis of hypoparathyroidism. The nurse
should monitor the client closely for the related problem of:
a) severe hypotension.
b) excessive thirst.
c) profound neuromuscular irritability.
d) acute gastritis. - ✔ ✔ c) profound neuromuscular irritability.
Explanation:
Hypoparathyroidism may slow bone resorption, reduce the serum calcium level, and cause profound
neuromuscular irritability (as evidenced by tetany). Hypoparathyroidism doesn't alter blood pressure or
affect the thirst mechanism, which usually is triggered by fluid volume deficit. Gastritis doesn't cause or
result from hypoparathyroidism.
A client is being evaluated for hypothyroidism. During assessment, the nurse should stay alert for:
,a) flushed, warm, moist skin.
b) systolic murmur at the left sternal border.
c) exophthalmos and conjunctival redness.
d) decreased body temperature and cold intolerance. - ✔ ✔ d) decreased body temperature and
cold
Explanation:
Hypothyroidism markedly decreases the metabolic rate, causing a reduced body temperature and cold
intolerance. Other signs and symptoms include dyspnea, hypoventilation, bradycardia, hypotension,
anorexia, constipation, decreased intellectual function, and depression. Exophthalmos; conjunctival
redness; flushed, warm, moist skin; and a systolic murmur at the left sternal border are typical findings
in a client with hyperthyroidism.
A client is receiving long-term treatment with high-dose corticosteroids. Which of the following would
the nurse expect the client to exhibit?
a) Hypotension
b) Pale thick skin
c) Moon face
d) Weight loss - ✔ ✔ c) Moon face
Explanation:
Clients who are receiving long-term high-dose corticosteroid therapy often develop a cushingoid
appearance, manifested by facial fullness and the characteristic moon face. They also may exhibit
weight gain, peripheral edema, and hypertension due to sodium and water retention. The skin is usually
thin, and ruddy.
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) Details about the size of the organ and its location
, b) The concentration of a substance in plasma
c) The client's blood sugar level
d) The functioning of endocrine glands - ✔ ✔ d) The functioning of endocrine glands
Explanation:
Measuring blood hormone levels helps determine the functioning of endocrine glands. A
radioimmunoassay determines the concentration of a substance in plasma. The measurement of blood
hormone levels will not reveal a client's blood sugar level. Radiographs of the chest or abdomen
determine the size of the organ and its location.
A client is suspected to have a pituitary tumor due to signs of diabetes insipidus. What initial test does
the nurse assist the client with preparing for?
a) Radioactive iodine uptake test
b) A nuclear scan
c) Magnetic resonance imaging (MRI)
d) Radioimmunoassay - ✔ ✔ c) Magnetic resonance imaging (MRI)
Explanation:
A computed tomography (CT) or magnetic resonance imaging (MRI) scan is performed to detect a
suspected pituitary tumor or to identify calcifications or tumors of the parathyroid glands. A radioactive
iodine uptake test would be useful for a thyroid tumor. Radioimmunoassay determines the
concentration of a substance in plasma.
A client sustained a head injury when falling off of a ladder. While in the hospital, the client begins
voiding large amounts of clear urine and states he is very thirsty. The client states that he feels weak and
has had an 8-lb weight loss since admission. What should the client be tested for?
a) Hypothyroidism
b) Syndrome of inappropriate antidiuretic hormone secretion (SIADH)
c) Pituitary tumor
