Question 1

While checking the lab results for a patient diagnosed with Graves disease, the nurse would expect the T₃ level to be abnormally:

Accepted Answer

Graves disease is an autoimmune disorder that causes the thyroid gland to produce too much thyroid hormone. This can lead to a number of symptoms, including weight loss, increased heart rate, and anxiety. The T3 level is a measure of the amount of thyroid hormone in the blood. In Graves disease, the T3 level is typically abnormally high.

Question 2

A patient diagnosed with thyroid carcinoma would be expected to have T₃and T₄ levels that are:

Accepted Answer

C

Question 3

Visual disturbances are a common occurrence in patients with untreated Graves disease.The endocrinologist explains to the patient that the main cause of these complications is:

Accepted Answer

The main cause of visual disturbances in Graves' disease is due to orbital edema and protrusion of the eyeball, also known as exophthalmos, which is caused by inflammation and swelling of the tissues around the eyes.

Question 4

When considering hypothyroidism, the basal metabolic rate is unusually:

Accepted Answer

Hypothyroidism is characterized by an underactive thyroid gland, which leads to a decrease in the production of thyroid hormones. These hormones are crucial for regulating metabolism, so their deficiency results in a lower basal metabolic rate.

Question 5

A 54-year-old patient with pulmonary tuberculosis is evaluated for syndrome of inappropriate ADH secretion (SIADH).Which electrolyte imbalance would be expected in this patient?

Accepted Answer

SIADH is characterized by excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia.

Question 6

A patient presents with breast discharge, dysmenorrhea, and excessive excitability.Tests reveal that all pituitary hormones are elevated.What does the nurse suspect as the most likely cause for these assessment findings?

Accepted Answer

A pituitary adenoma is a tumor in the pituitary gland that can cause overproduction of pituitary hormones, leading to symptoms such as breast discharge, menstrual irregularities, and changes in mood or behavior.

Question 7

Which hypothyroid diagnosis is supported by low levels of TSH?

Accepted Answer

Secondary hypothyroidism is caused by a problem with the pituitary gland or hypothalamus, leading to low TSH levels.

Question 8

Which assessment result would the nurse expect to find associated with a patient diagnosed with Graves disease?

Accepted Answer

Graves disease is an autoimmune disorder characterized by high levels of thyroid-stimulating autoantibodies, which stimulate the thyroid gland to produce excess thyroid hormones.

Question 9

A nurse is caring for a patient diagnosed with SIADH.What severe complication should the nurse assess for?

Accepted Answer

SIADH can lead to hyponatremia, which can cause neurologic damage due to cerebral edema and increased intracranial pressure.

Question 10

A patient is admitted to the intensive care unit with a closed head injury sustained in a motorcycle accident.The injury has caused severe damage to the posterior pituitary.Which of the following complications should the nurse anticipate?

Accepted Answer

Damage to the posterior pituitary can lead to a deficiency in antidiuretic hormone (ADH), resulting in diabetes insipidus, which causes dehydration from polyuria.

Question 11

Diabetes insipidus, diabetes mellitus (DM), and SIADH share which of the following assessment manifestations?

Accepted Answer

Thirst is a common symptom in diabetes insipidus, diabetes mellitus, and SIADH due to fluid imbalance and the body's response to maintain homeostasis.

Question 12

Besides hyposecretion and hypersecretion, endocrine system dysfunction can result from:

Accepted Answer

Endocrine system dysfunction can result from abnormal receptor activity, where receptors may be insensitive or overly sensitive to hormones, affecting the body's response to hormone levels.

Question 13

A patient presents with polyuria and extreme thirst and is given exogenous ADH.For which of the following conditions would this treatment be effective?

Accepted Answer

Exogenous ADH is effective in neurogenic diabetes insipidus because the condition is due to a deficiency of ADH production, and providing ADH externally can compensate for this deficiency.

Question 14

While planning care for a patient from general anesthesia, which principle should the nurse remember? A side effect of some general anesthetic agents is _____ diabetes insipidus.

Accepted Answer

Nephrogenic diabetes insipidus can be a side effect of some general anesthetic agents, as they can affect the kidneys' ability to respond to antidiuretic hormone.

Question 15

What common neurologic disturbances should the nurse assess for in a patient with a pituitary adenoma?

Accepted Answer

Pituitary adenomas can compress the optic chiasm, leading to visual disturbances such as loss of peripheral vision.

Question 16

Palpation of the neck of a patient diagnosed with Graves disease would most likely reveal:

Accepted Answer

Graves disease is characterized by diffuse thyroid enlargement due to the overactivity of the thyroid gland.

Question 17

A patient diagnosed with Graves disease is admitted to a medical-surgical unit.Which of the following symptoms would the nurse expect to find before treatment?

Accepted Answer

Graves disease is an autoimmune disorder that leads to hyperthyroidism, causing symptoms such as a rapid heart rate and hot, moist skin due to increased metabolism.

Question 18

A 44-year-old patient with pulmonary tuberculosis is evaluated for SIADH.Which assessment finding would support this diagnosis?

Accepted Answer

SIADH (Syndrome of Inappropriate Antidiuretic Hormone) is characterized by excessive release of antidiuretic hormone, leading to water retention and concentrated urine due to decreased urine output.

Question 19

A 45 year old diagnosed with Graves disease underwent surgical removal of the thyroid gland.During the postoperative period, the patient's serum calcium is low.The most probable reason for her low serum calcium is:

Accepted Answer

During thyroid surgery, the parathyroid glands, which regulate calcium levels, can be inadvertently damaged or removed, leading to hypoparathyroidism and resulting in low serum calcium levels.

Question 20

What is the most common cause of elevated levels of antidiuretic hormone (ADH) secretion?

Accepted Answer

Cancer, particularly small cell lung cancer, is a common cause of elevated ADH secretion due to ectopic production of the hormone.
