Chapter54 Flashcards
Identify the following test
A stimulus may be provided to determine whether the endocrine gland is capable of normal production. Measured amount of hormones or substances are minister to stimulate the target gland to produce its hormone . Then these hormones are measured.
Stimulation test is performed on a client with suspected under activity of the endocrine gland.
Figure of almost levels to increase with a stimulation test indicates what?
Hypo function. Example hypothyroidism
What test is used when hormone that was or high or in the upper range of normal? Agents that deplete activity of hormone production or ministered to determine if there’s normal negative feedback.
Suppression test
Fater of hormone production to be suppress during standardized testing when performing a suppression test indicates what?
Hyperfunction. Example hyperthyroidism secrets too many hormones
Identify the following diagnostic test.
Measures the absorption of iodine isotope to see how about thyroid gland is function
Radioactive iodine uptake
Radioactive iodine uptake
Once the radioactive iodine is introduced the amount of radioactivity is measured in how many hours and then again at how many hours
2 to 4 hours and again at 24 hours
The thyroid function test measures the absorption of iodine. What are the normal values in how many hours
3% to 10% at 2 to 4 hours and 5% to 30% in 24 hours anything below that or over that is abnormal function
In a radioactive iodine uptake test any values about 10% in a span of 24 hours or above 30% in the span of 24 hours indicates what?
hyperthyroidism, decrease iodine intake, increase iodine excretion
Describe the following body system
Maintenance and regulation of vital functions response to stress an injury to inflammatory response growth and development energy metabolism reproduction food electrolyte an acid base balance
Endocrine system
Identify the following test.
Used when hormone levels are high or in the upper range of normal, an agent is introduced to the body to suppress response and determine whether there is normal negative feedback. when chemicals are introduced and there is a failure of hormone production suppression, that would indicate a hyperfunction.
Suppression test
When you have a decrease in radioactive iodine Uptake this will indicate
Hypothyroidism and low T4 level use of anti-thyroid medication thyroiditis myxedema
Myxedema -
nounMEDICINE
swelling of the skin and underlying tissues giving a waxy consistency, typical of patients with underactive thyroid glands.
the more general condition associated with hypothyroidism, including weight gain, mental dullness, and sensitivity to cold.
T3 and T4 resin uptake test
What does it diagnose What do these forms T3 T4 regulate? What are the normal values for T3 - T4 - Thyroxine, free (FT4)-
They are blood test that diagnosed disorders with the thyroid
They regulate thyroid stimulating hormone TSH
T3 - 8o to 230
T4 - 5-12
Thyroxine, free (FT4)-0.8 - 2.4
Which hormone elevates with hyperthyroidism decreases with the aging process and maybe decreased with hypothyroidism?
Which hormone is increased with hyperthyroidism and decrease with hypothyroidism?
T3
T4
Which blood test is used to differentiate the diagnosis of primary hypothyroidism?
What are the normal values?
What do elevated values indicate and what to decrease values indicate?
Thyroid stimulating hormone TSH
0.2 to 5.4
Elevated values indicate primary hypothyroidism
Decrease values indicate hyperthyroidism or secondary hypothyroidism.
Identify the following procedure and what do you reassure the client
Performed to identify not to support role in the thyroid a radio isotope of iodine or technetium is administered.
What would invalidate the exam?
Regarding medication what are you check with the healthcare provider?
Thyroid scan
Reassure that radioactive medication is not dangerous to self or others
If patient has received contrast agents within the past three months
If you have the greenlight to discontinue Iodine medications for 14 days before test
