COMPLETE REAL EXAM QUESTIONS AND CORRECT
VERIFIED ANSWERS/ GRADED A+ (MOST RECENT!!)
Prealbumin .....ANSWER.....Levels below 11 mg/dL indicate the
presence of malnutrition. Decreased levels may result from stress,
inflammation, surgery, and renal failure. Measures the amount of
protein contained in the internal organs. Protein is synthesized in
the liver and broken down by the kidneys. Determine recent
nutritional status.
Albumin .....ANSWER.....Used to determine liver function. Is
synthesized in the liver and accounts for almost half of the total
serum protein in the body. Levels should be included on the initial
chemistry profile for nutritional screening purposes and
monitored during hospitalization to determine the presence of an
ample supply of protein over an extended period of time. The
,Page 2 of 60
synthesis of protein may be affected by non nutritional factors
such as cirrhosis, acute stress, congestive heart failure, and
hypoxia. Decreased levels may be caused by renal and liver
disorders, altered fluid status, medications, chronic diseases, and
malnutrition. Elevated levels may result from decreased fluid
balance, exercise, or medications.
Transferrin .....ANSWER.....Transports iron in the body and is
sensitive to a decrease in protein and iron stores, as seen in iron
deficiency anemia and kwashiorkor. Levels may be elevated in
acute fasting, chronic infection, inflammation, burns, or pernicious
anemia. Levels elevate as iron deficiency worsens and decrease
as the iron level responds to treatment and returns to within an
acceptable range
Hemoglobin .....ANSWER.....Laboratory values are used to
identify the number and percentage of circulating erythrocytes,
their ability to provide oxygen to the cells, and the body's iron
,Page 3 of 60
store status. Iron is essential. It assists in gas exchange within the
lungs and helps meet the oxygen demands of the body. If iron
stores are depleted, less oxygen is available to meet the
demands of the body, resulting in signs and symptoms such as
fatigue, pallor, shortness of breath, and rapid respirations. Iron
deficiency anemia indicated by low levels usually is treated by
providing iron in the form of oral supplements or intramuscular
injections. In severe circumstances, iron may be administered
intravenously. People with low levels should be encouraged to
increase their intake of foods that are high in iron, such as liver,
dark green leafy vegetables, seafood, and bran.
Hemoglobin .....ANSWER.....Laboratory values are used to
identify the number and percentage of circulating erythrocytes,
their ability to provide oxygen to the cells, and the body's iron
status. Indicates the number and size of the red blood cells found
in whole blood and are expressed as the percentage of total
, Page 4 of 60
blood balance occupied by the erythrocytes. Low levels are
indicative of anemia. The size and shape of the red blood cell
can be related to the type of anemia from which a person is
suffering.
Blood Urea Nitrogen (BUN) and Creatinine
.....ANSWER.....Commonly ordered together as part of a basic or
comprehensive metabolic profile. Are used to primarily to
evaluate kidney function in people with disease processes known
to affect the kidneys, such as diabetes or hypertension. Levels
determine the extent of kidney dysfunction, its progression, and
the effectiveness of treatment. Elevated levels may be a result of
dehydration, atherosclerosis, or injury to the kidneys from
infection or trauma.
Lab Value: Prealbumin (mg/dL) .....ANSWER.....Half-Life (Days): 2
Normal: 16-30
Mild: 10-15
