NSG 550 Diagnostics Exam 1 Practice
Questions Solved Correctly.
precision of a test - Answer Ability of the test to yield the same results on multiple trials using the same
sample (repeatability)
accuracy of a test - Answer does the test measure what is is designed to measure
Sensitivity - Answer determine who has the disease
highly sensitivity gives low false NEG
Specificity - Answer determine who does NOT have the disease
highly specific gives low false POS
Choosing Wisely Campaign - Answer Developed by the American Board of Internal Medicine to aims to
promote conversations between physicians and patients by helping patients choose care that is:
Supported by evidence
Not duplicative of other tests or procedures already received
Free from harm
Truly necessary
ACTH (adrenocorticotropic hormone) - Answer Stimulates adrenal cortex to release glucocorticoids
(cortisol)
response to stress
fights infection
regulates blood sugar and blood pressure and metabolism
who makes acth - Answer pituitary gland
, what to draw when looking for endocrine disease process - Answer acth
cortisol
cushings syndrome vs disease - Answer disease too much acth and cortisol
syndrome too much cortisol
Addison's disease - Answer a condition that occurs when the adrenal glands do not produce enough
cortisol or aldosterone
cortisol - Answer stress hormone released by the adrenal cortex
High ACTH levels and high cortisol - Answer Cushing Disease or Ectopic ACTH production
high acth and low cortisol - Answer Addison's disease
Low ACTH, high cortisol - Answer Cushing syndrome
Low ACTH, low cortisol - Answer hypopituitarism
ACTH stim test - Answer 250 mcg Cosyntropin; measure cortisol before & 30 & 60 min after injxn; pre
or post >18: R/O adrenal insuff
Aldosterone - Answer "salt-retaining hormone" which promotes the retention of Na+ by the kidneys.
na+ retention promotes water retention, which promotes a higher blood volume and pressure
antidiuretic hormone (ADH) - Answer influences the absorption of water by kidney tubules
cause of low osmolality - Answer low adh
DI
