Cards

Term
Pituitary Gland
Definition
1.the master gland;located at the base of the brain
2. influenced by the hypothalamus and directly affects the function of other endocrine glands
3. promotes the growth of body tissue, influences water absorption by the kidney and controls sexual development and function
Term
Pituitary Gland Hormones of the Anterior Lobe
Definition
1. (GH) Growth Hormone
2. (TSH) Thyroid Hormone
3. (ACTH) Adrenocorticotropic Hormone
4. (LH) Leutininzing Hormone
5. (PH) Prolactin Hormone
6. (FSH) Follicle Stimulating Hormone
Term
Pituitary Gland Hormones of the Posterior Lobe Storage
Definition
These hormones are produced in the hypothalamus stored in the posterior lobe and released into the blood stream

1. Oxtytocin
2. Vasopressin (anti-diuretic hormone)
Term
Adrenocorticotropic Hormone (ACTH)
Definition
ACTH's principal function is to stimulate the adrenal glands (located near the kidneys) to secrete a group of steroid hormones called glucocorticoids. It is only effective if the adrenal gland is still functioning. Today, ACTH is given by IM or IV and is often prescribed to reduce inflammation (tenderness and swelling caused by infection, injury, or illness) and to relieve pain. It is used for MS, Organ Transplants, Rheumatoid Arthritis, Lupus and Cancer. Sometimes results in the feeling of euphoria.

Term
Growth Hormone (GH)
Definition
stimulates growth of body tissues especially muscle and bone
Term
Thyroid Stimulating Hormone (TSH)
Definition
stimulates thyroid to produce thyroxine(T4), triiodothyronine (T3), and thyrocalcitonin
Term
Leutinizing Hormone (LH)
Definition
stimulates secretion of sex steroids from the gonads; in males, the testes secretion of testosterone, and in females, the ovaries, secretion of testosterone, which is converted into estrogen.
Term
Prolactin hormone (PH)
Definition
stimulates the mammary glands development and milk production
Term
Follicle Stimulating Hormone (FSH)
Definition
stimulates the maturation of ovarian follicles in females and sperm production and sperm cell maturation.
Term
Adrenocorticotropic considerations
Definition
*has many drug interatactions
*must be tapered off if on for any length of time
*won't show normal signs of infection
*side effects- electrolyte and fluid imbalance, susceptible to infections, behavioral changes, hyperglycemia, peptic ulcers formation, delayed wound healing, cataracts, osteoporosis
Term
Somatropin and somatrem
Definition
*recombinantly made growth hormone (GH)
*stimulates skeletal growth in patients deficient in (GH) hypopituitary dwarfism
Term
Octreotide (Sandostatin-GH inhibitor)
Definition
alleviates or eliminates certain symptoms of carcinoid tumors
*acromegaly-over growth of bone
Term
Oxytocin-(Pitocin) posterior pituitary
Definition
stimulates contractions of the uterus
Term
Vasopressin (anti-diuretic hormone) from the posterior lobe of the pituitary gland
Definition
used to treat diabetes insipidus(condition in which the body produces an abnormally large amount of urine))
Term
Desmopressin
Definition
*sometimes use for the treatment of enuresis (bed wetting)
*treatment of mild Hemophilia A (is a hereditary bleeding disorder caused by a lack of a blood clotting factor, without it the blood cannot clot properly to stop bleeding.)
Term
Nursing implications for antidiuretic hormones (Vasopressin and Desmopressin)
Definition
*increase in BP
*headache
*lethargy
*nausea
*abdominal cramps
*tremors
*sweating
*vertigo (dizziness)
