NSG 550 Exam 1 | Diagnostic Reasoning for
Nurse Practitioners GRADED A+ 2026
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
