A client comes to a scheduled appointment in the endocrine clinic. The primary care physician referred the client, suspecting acromegaly. Knowing the usual testing involved, the nurse should educate the client about which lab/diagnostic procedure?

A suppression test Rationale: Suppression tests are used when hyperfunction of an endocrine organ is suspected.

Which complications could occur when an adult client has a secreting tumor of the anterior pituitary gland that results in excess hormone production? Select all that apply:

Accromalgy Diabetes mellitus Metrorrhagia

The nurse is assessing a client with thyrotoxicosis and the nurse is explaining how the thyroid gland is stimulated to release thyroid hormones. The nurse should describe what process?

Action of releasing hormones from hypothalamus

The nurse is caring for a client who has hyperthyroidism. When evaluating the laboratory test results, which alteration does the nurse anticipate will be present?

Decrease in TSH Rationale: When the sensors detect a decrease in hormone levels, they initiate changes that cause an increase in hormone production. When hormone levels rise above the set point of the system, the sensors cause hormone production and release to decrease

A client experiences an increase in cortisol as a result of Cushing disease. Which hormonal responses demonstrate the negative feedback mechanism?

Decreased ACTH

The nurse is reviewing the test results of a client who was given thyrotropin-releasing hormone (TRH) to evaluate the function of the pituitary gland. The nurse would recognize pituitary dysfunction as:

Decreased TSH levels

An adult client presents to the emergency department after an episode of syncope. Blood pressure is low and the pulse is thready and rapid. The client frequently voids large amounts of pale, clear urine. Lung sounds are clear and skin turgor is inelastic. Which endocrine disorder is the likely cause of these manifestations?

Diabetes insipidus

Which type of imaging is preferred to evaluate the bone density of a client with hyperparathyroidism?

Duel energy X-ray absorptiometry (DXA) scan

Which hormone is secreted based on a cyclic rather than a diurnal manner?

Follicle Stimulating Hormone

A client has developed a tumor of the anterior pituitary gland. The nurse is aware that the client is at risk for alterations in which body function? Select all that apply

Growth and metabolism Function of the thyroid gland Glucocorticoid hormone levels Function of the gonads

A client with hyperthyroidism is being treated with medication that blocks the activity of thyroid-stimulating hormone. Her care team has determined that she has been overproducing TSH. This client will have lost her ability to:

Have negative feedback regulation

An adult client is scheduled for testing of a suspected growth hormone (GH)-secreting tumor. Which result from the glucose suppression test would confirm the condition?

Increased Gh secretion

Following a meal, a client's blood glucose level has increased. In addition, the client's pancreas has increased the amount of insulin produced and released. Which phenomenon has occurred?

Increased hormone level according to a negative feedback

Which are examples of a negative feedback system. Select all that apply:

Insulin and glucagon Cortisol and adrenocorticotropic Somatostatin and TSH Calcium and parathyroid

A client develops hypocalcemia after thyroid surgery. Which hormonal imbalance caused this complication?

Lack of PTH

A middle-aged female client has been diagnosed with a thyroid condition. The nurse educates the client about the prescription and needed follow-up lab work, which will help regulate the dosage. The client asks, "Why do I not return to the clinic for weeks, since I am starting the medication tomorrow morning?" The nurse bases the answer on the knowledge that thyroid hormones:

May take days for the full effect to occur, based on MOA

An adult client with suspected hypothyroidism is scheduled for a thyrotropin-releasing hormone (TRH) stimulation test to evaluate pituitary response. Which test results would confirm secondary hypothyroidism?

No increase in TSH

The nurse is caring for a client who has decreased secretion of arginine vasopressin from the posterior pituitary gland. When evaluating the client's fluid and electrolyte status, which alteration does the nurse anticipate will be present?

Polyuria

A client receives steroids for several months to treat an inflammatory condition. Which action by the primary health care provider indicates an understanding of the negative feedback mechanism when the client no longer needs the medication?

Prescribe a tapering dose of medication over weeks

The nurse is caring for a client who is receiving exogenous corticosteroids for rheumatoid arthritis. Recognizing that hormone levels are regulated by negative feedback, which laboratory test result does the nurse anticipate uncovering when reviewing the medical record?

Reduction in ACTH

A client asks the nurse what causes the secretion of growth hormone (GH) and adrenocorticotrophic hormone (ACTH) to fluctuate. The best response by the nurse would be:

Sleep-wake cycles Rationale: Growth hormone (GH) and adrenocorticotropic hormone (ACTH) have diurnal fluctuations that vary with the sleep-wake cycles. Others, such as the female sex hormones, are secreted in a complicated cyclic manner. The levels of hormones such as insulin and antidiuretic hormone (ADH) are regulated by feedback mechanisms that monitor substances such as glucose (insulin) and water (ADH) in the body.

The kidney produces 1,25-dihydroxyvitamin D. This form of vitamin D is responsible for which action in the body?

Stimulates calcium absorption from the intestine

Which events are involved in the negative feedback mechanism that keeps the serum thyroid hormone level within appropriate range? Select all that apply.

Stimulation of sensors in the hypothalamus Stimulation of sensors in the anterior pituitary Decrease in secretion of TSH Increased levels of thyroid hormone

A client with a newly diagnosed adrenal tumor asks the nurse, "So what kind of hormones will be affected if I have my adrenal gland removed?" Which response(s) by the nurse is accurate to relay to this client? Select all that apply.

You will have changes in your sympathetic nervous system response to stress It could affect sodium and potassium levels Blood glucose levels may become elevated

The nurse cares for a client with severe chronic obstructive pulmonary disease who has been taking oral steroids for several years. Which response in the client's endocrine control will the nurse expect?

Suppression of the clients hypothalamic-pituitary-target cell system
