Test 3 Flashcards
The hypothalamus and pituitary gland referred to as
neuroendocrine system
the anterior pituitary gland
adenohypophysis
posterior pituitary gland
neurohypophysis
Anterior pituitary gland hormones are (TVBH)
thyroid-stimulating hormone (TSH), growth hormone (GH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), luteinizing and prolactin hormone
Hormones of the posterior pituitary gland
antidiuretic hormone (ADH), oxytocin
Drugs that mimic the action of endogenous pituitary hormones are
cosyntropin, somatropin, somatrem, vasopressin, and desmopressin.
A drug that antagonizes the actions of endogenous pituitary hormones is
octreotide
Drugs are generally used either to
replace or diagnose patient’s hormonal functions
Another name for corticotropin is
Adrenocorticotropic (ACTH)
Cosyntropin (made coricotropin) travels to the adrenal cortex, located just above the kidney, and stimulates the secretion of what?
cortisol
Cortisol is good for what
anti-inflammatory response including the leukocyte functions and scar tissue response
Cortisol promotes renal retention of sodium, which can result in
edema and hypertension
A drug that antagonizes the effects of natural GH by inhibiting GH release
Octreotide (somatostatin), reduces plasma concentrations of vasoactive intestinal polypeptide VIP
The drugs that mimic GH are
somatropin and somatrem
Drugs that stimulate various anabolic (tissue-building) processes, liver glycogenolysis (to raise blood sugar levels), lipid mobilization from body fat stores, and retention of sodium, potassium, and phosphorus and promote linear growth in children who lack normal amounts of the endogenous hormone are
GH (somatropin/somatrem)
A protein secreted by a type of tumor that causes profuse watery diarrhea. Hint VIPoma
vasoactive intestinal polypeptide
The drugs that affect the posterior pituitary gland, such as vasopressin and desmopressin, mimic the actions of
antidiuretic hormone (ADH).
vasopressin and desmopressin does what?
increase water resorption
a potent vasoconstrictor in larger doses and is therefore used in certain hypotensive emergencies, such as vasodilatory shock (septic shock) or pulseless cardiac arrest.
vasopressin
what stops bleeding of esophageal varices
vasopressin
useful in treating certain blood disorders including hemophilia A and type I von Willebrand’s disease.
desmopressin
used for nocturnal enuresis and is a synthethic vasopressin.
desmopressin
used in the diagnosis of adrenocortical insufficiency
Cosyntropin
human GH produced by recombinant technology which are are also used for wasting associated with human immunodeficiency virus (HIV) infection.
Somatropin and somatrem are
useful in alleviating certain symptoms of flushing and potentially life-threatening hypotension associated with a carcinoid crisis.
Octreotide
used to prevent or control polydipsia (excessive thirst), polyuria, and dehydration in patients with diabetes insipidus caused by a deficiency of endogenous ADH
Vasopressin and desmopressin
Because of their vasoconstrictor properties, they are useful in the treatment of various types of bleeding, in particular gastrointestinal hemorrhage.
Vasopressin and desmopressin
In the assessment of patients receiving pituitary hormones measure…
vitals, sugar and weight
With octreotide, the prescriber may order an electrocardiogram (ECG) may require special dosing if
there is decreased liver and kidney function
Potential side effects of growth hormones are
hyperglycemia, hypothyroidism, and hypercalciuria.
