What is the route of administration for bromocriptine?
Oral
A patient is experiencing a prolonged labor and her contractions are ineffective. Which agent would the nurse expect to be ordered?
Oxytocin
Antidiuretic hormone functions by causing all of the following EXCEPT:
Inhibiting secretion of thyrotropin.
A client is to receive nafarelin. The nurse would instruct the client in administering this drug by which route?
Intranasal
Which is a factor that inhibits the release of hormones?
Somatostatin
After teaching a group of students about growth hormone agonists and antagonists, the instructor determines that additional teaching is needed when the students identify which agent as a growth hormone antagonist?
Somatropin
Which agent would the nurse identify as a growth hormone agonist?
Somatropin
The nurse is preparing to administer octreotide. The nurse expects to administer this drug by which route?
Subcutaneous
A client's current drug regimen includes intranasal administration of desmopressin acetate. In this client's plan of nursing care, what is the most likely desired outcome of treatment?
The client's urine output will not exceed 80 mL/h.
A 13-year-old boy who is in the first percentile of height for his age has been referred for care. Which assessment finding would contraindicate the safe and effective use of somatropin to treat his growth deficiency?
The epiphyses of the boy's long bones have closed.
The nurse is assessing a child who is receiving growth hormone therapy. What would the nurse identify as suggesting glucose intolerance?
Thirst
An adult client diagnosed with human immunodeficiency virus (HIV) is prescribed somatropin (Serostim). The nurse should explain that this drug is primarily used in HIV clients for which purpose?
To stop severe muscle wasting
Which hormone is released in the presence of low blood volume?
antidiuretic hormone (ADH)
Which instructions would be an important component of teaching a patient to self-administer nasal spray?
Use a firm squeeze to deliver the drug.
What is the most effective method to determine a client's ability to self-administer their prescribed nasal desmopressin?
Watch them administer a scheduled dose of the medication.
Gonadotropins are classified in which pregnancy category?
category X
Which hormone stimulates the adrenal cortex to produce and secrete adrenocortical hormones?
corticotropin
What causes the release of adrenocorticotropic hormone in response to a client's psychological and physiological stress?
corticotropin-releasing hormone or factor (CRH or CRF)
