LATEST VERSION NSG 550 Diagnostics Exam 1
GRADED A QUESTIONS AND ANSWERS 2025
antidiuretic hormone (ADH) - CORRECT ANSWER influences the absorption of
water by kidney tubules
cause of low osmolality - CORRECT ANSWER low adh
DI
Antithyroidglobulin antibody - CORRECT ANSWER level of antibodies
protein found in thyroid cells
less than 116IU
Anion Gap - CORRECT ANSWER Difference between the concentrations of serum
cations and anions: determined by measuring the concentrations of sodium
cations and chloride and bicarbonate anions.
low anion gap - CORRECT ANSWER hypoalbuminemia
high anion gap - CORRECT ANSWER diabetic ketosis, due to increased amount of
ketones acquired from diet
diarrhea
poision
dehydration
calcitonin - CORRECT ANSWER decreases blood calcium levels
MADE BY THYROID
tumor marker
elevated in thyroid cancers
low serum co2 and high anion gap - CORRECT ANSWER could mean DKA, needs
further investigated
what opposes parathyroid hormone - CORRECT ANSWER calcitonin
, C-peptide levels - CORRECT ANSWER marker to determine the amount of insulin
a pt is making
released with insulin
low c-peptide levels indicate - CORRECT ANSWER not enough insulin type 1
Diabetes Autoantibody Panel - CORRECT ANSWER type 1 diabetes
HGB A1C levels indicating diabetes - CORRECT ANSWER above 6.5%=diabetic
5.7-6.5%=prediabetic
fasting glucose >126=diabetic
plasma glucose >200mg for regular glucose check=diabetic
diabetes diagnoses - CORRECT ANSWER must use more than one test
hgba1c not always available
Glucose (postprandial) - CORRECT ANSWER after meal to determine insulin
usage
Insulin assay - CORRECT ANSWER assess beta cell function
lactic acid - CORRECT ANSWER Produced in muscle cells from the reduction of
pyruvate (under anaerobic conditions) to regenerate NAD+ so that glycolysis can
continue. A rise in lactic acid usually accompanies an increase in physical activity.
elevated lactate - CORRECT ANSWER insufficient perfusion and O2 delivery
shock anemia heart failure
liver disease
kidney
CAN BE ELEVATED IN EXERCISE
