NCP PRACTICE TEST QUESTIONS
AND ANSWERS
What are 5 factors to consider in taking a patients dietary history - Answer- weight
changes, usual meal patterns, appetite, satiety, and likes/dislikes
What is frequently the first region of the body to show signs of vitamin deficiency -
Answer- the tongue and oral cavity
What are ways that food in the stomach can reduce the absorption of a drug - Answer-
to delay digestion, bind to the minerals in food, or adhere to food particles
What is the most common nutrient deficiency in the US? - Answer- iron deficiency
What is the most common cause of anemia - Answer- iron deficiency
What is hemoglobin - Answer- an iron containing molecule in RBCs that carries oxygen
and carbon dioxide
When does hemoglobin become abnormally low - Answer- in the last stage of iron
depletion
What is the primary transport protein to which drugs bind - Answer- albumin
Primordial prevention - Answer- Preventing the development of CVD risk factors in
children and preventing future CVD by effectively managing any identified risk factors
Primary prevention - Answer- Involves risk factor reduction in patient with no evidence
or diagnosis of a disease
What are 3 examples of primary prevention - Answer- smoking cessation, decreasing
LDL, or decreasing BP
What is considered the most effective approach for reducing disease prevalence -
Answer- primary prevention
Secondary prevention - Answer- risk factor reduction in patients who have evidence or
diagnosis of disease (atherosclerosis)
, Tertiary prevention - Answer- risk factor reduction in patient who have already
experienced disease complications (MI)
What are the 5 biomarkers of impaired iron status - Answer- hemoglobin, ferritin,
transferrin, soluble transferrin receptors, and erythrocyte protoporphyrin
is hemoglobin a suitable indicator or early iron deficiency? why - Answer- no, because it
does not become abnormally low until the last stage of iron depletion
hemoglobin does not distinguish between.... - Answer- iron deficiency anemia and
anemia of inflammation
what is ferritin - Answer- the primary intracellular iron-storage protein that is an acute
phase protein
as iron stores decrease.... what happens to ferritin - Answer- ferritin decreases
what is the most sensitive indicator of early iron deficiency - Answer- serum ferritin
concentration
when is ferritin increased and why - Answer- during acute and chronic inflammation
because it is an acute phase protein
what is transferrin - Answer- the primary iron transport protein
how is iron transported in the blood - Answer- bound to transferrin
Under normal circumstances, _______% of transferrin iron binding sites are "saturated"
with iron - Answer- 30%
what happens to transferrin during iron deficiency - Answer- transferrin saturation
decreases and total iron binding capacity increases
serum concentration of soluble transferrin receptors is directly proportional to: .....
especially when? - Answer- the body's requirement for iron, especially in the erythrocyte
producing cells of the bone marrow
when does serum concentration of soluble transferrin receptors increase - Answer- in
early iron deficiency before anemia develops
when is serum concentration of soluble transferrin receptors valuable? - Answer- in
diagnosing iron deficiency and monitoring erythropoiesis, especially before anemia
develops
what are soluble transferrin receptors not affected by - Answer- inflammation or
infection
