Module 14 Flashcards
A patient with an excessive appetite has:
- anorexia
- polyphagia
- hyperglycemia
- polyphasia
polyphagia
The prefixes poly- and hyper- can both mean excessive, so knowing that only eliminates anorexia as an answer. Phag/o means to eat or swallow, so a person with an excessive appetite has polyphagia. Polyphasia is not a real term.
The condition of deficient sodium in the blood is:
- hyponatremia
- hypercalcemia
- hypersaltemia
- hypokalmemia
hyponatremia
When sodium (natr/o) levels in the blood are** low (hypo-)**, the condition is known as hyponatremia. The condition of low blood potassium levels is called hypokalemia. Hypercalcemia is the condition of excessive levels of calcium in the blood.
Graves disease is an extreme form of:
- hypothyroidism
- hyperthyroidism
- Addison disease
- Cushing syndrome
hyperthyroidism
Graves disease is an extreme form of hyperthyroidism, caused by the excessive (hyper-) production of thyroid hormone. Hypothyroidism is deficient thyroid hormone production. Addison disease and Cushing syndrome are adrenal gland disorders.
Radioactive iodine uptake scans are used to test for:
- hyperparathyroidism
- hyperthyroidism
- hypothyroidism
- hypoparathyroidism
hyperthyroidism
Radioactive iodine uptake scans (RAIU) test thyroid function by measuring the gland’s ability to concentrate and retain iodine. RAIU is useful to test for hyperthyroidism, because with hyperthyroidism, absorption of iodine is increased and its uptake can be visualized on an image produced by a thyroid scan.
A lack of adrenal cortisol leads to which disorder?
- Cushing syndrome
- Addison disease
- Simmonds disease
- Graves disease
Addison disease
A lack of adrenal cortisol leads to Addison disease. An excessive secretion of adrenal cortisol leads to Cushing syndrome. A lack or deficiency of all pituitary hormones leads to Simmonds disease. Excessive thyroid hormone production leads to Graves disease.
The _____ gland is located in the center of the brain and secretes melatonin.
1. pineal
2. thyroid
3. adrenal
4. pituitary
pineal
The pineal gland is located in the center of the brain and secretes melatonin, which is thought to induce sleep.
Exophthalmia is:
- cancer of the endocrine system
- enlargement of the thymus gland
- enlargement of the thyroid gland
- protrusion of the eyeballs from their orbits
protrusion of the eyeballs from their orbits
Exophthalmia is a protrusion of the eyeballs from their orbits. A goiter is an enlargement of the thyroid gland.
The F in TFT stands for:
- fasting
- function
- free
- failure
function
TFT is the abbreviation for thyroid function test, a blood test that measures T3, T4, and calcitonin levels.
The endocrine system uses the ______ system and chemical messengers called _____ to regulate many body functions.
1. circulatory, hormones
2. respiratory, hormones
3. circulatory, glands
4. nervous, neurotransmitters
circulatory, hormones
The endocrine system is made up of glands that send chemical messengers called hormones through the bloodstream in the circulatory system to regulate a number of body functions, including metabolism, growth, reproduction, and water and electrolyte balances.
T3 is a hormone secreted by the:
- thyroid gland
- thymus gland
- adrenal medulla
- adrenal cortex
thyroid gland
T3 is the abbreviation for triiodothyronine, one of the hormones secreted by the thyroid gland.
The _____ cells of the islets of Langerhans produce glucagon.
- kappa
- beta
- delta
- alpha
alpha
The two main types of islets of Langerhans cells are alpha and beta cells. Alpha cells produce glucagon to increase blood glucose levels, and beta cells secrete insulin to decrease blood glucose levels when they are too high.
The exocrine function of the pancreas is to:
- stimulate key cells in the immune response
- release toxins through the skin
- regulate blood glucose levels
- release digestive enzymes into the small intestines
release digestive enzymes into the small intestines
The exocrine function of the pancreas is to release digestive enzymes through a duct into the small intestines. The endocrine function of the pancreas is to regulate blood glucose levels with the hormones glucagon and insulin.
Build a term for the excision of the head of the pancreas and duodenum.
- pancre/o + duoden/o + -ectomy
- duoden/o + pancre/o + -ectomy
- duoden/o + pancreat/o + -ectomy
- pancreat/o + duoden/o + -ectomy
pancreat/o + duoden/o + -ectomy
Pancreatoduodenectomy, also called the Whipple procedure, is used to treat pancreatic cancer by excision (-ectomy) of the head of the** pancreas (pancreat/o) **along with the duodenum (duoden/o).
The abbreviation for a radioactive iodine uptake scan is:
- RIU
- RIA
- RAI
- RAIU
RAIU
RAIU is the abbreviation for radioactive iodine uptake scan. Don’t confuse it with RIA, which is the abbreviation for radioimmunoassay studies.
An A1c test is used to measure average blood glucose during a ___ -month time span.
1. two
2. three
3. six
4. one
three
An A1c test measures the average blood glucose level over a three-month period. It is used to monitor a patient’s response to diabetes treatment.
The combining form for the pituitary gland is:
- hypophys/o
- adren/o
- hypothalam/o
- lob/o
hypophys/o
Hypophys/o is the combining form for the pituitary gland, or hypophysis. Lob/o means lobe; the pituitary gland has two lobes. Adren/o means adrenal gland.
