NURB 3050 Test 2 Questions AndAccurate Answers
Which finding should indicate to the nurse that a 5-year-old child has a normal
hemoglobin level? - Answer 2.12 g/dl
A nurse is teaching about a formed element of the blood that lives about 8 to 11 days.
Which element is the nurse describing? - Answer Platelets
A nurse is teaching about the type of mononuclear phagocyte that is located in the liver.
Which cells is the nurse describing? - Answer Kupffer cells
A nurse is checking the results of a white blood cell count differential. In a healthy client,
which cell count will be the highest? - Answer Neutrophils typically account for
approximately 40% to 60% of the white blood cell count differential. Bands are immature
neutrophils. Monocytes account for 8% or less of the white blood cell count differential.
Lymphocytes account for approximately 40% of the white blood cell count differential.
A Lee-White coagulation time is prescribed for a client. Which information indicates the
nurse correctly understands the blood property that is being evaluated? - Answer The
test measures the overall ability of blood to clot, as measured in minutes in a test tube.
When an elderly client bleeds, the erythrocytes are replenished more slowly. What is the
most probable cause for this finding? - Answer Iron depletion
A client has decreased levels of plasma proteins from a disorder in the organ that
produces plasma proteins. Which organ does the nurse monitor? - Answer Liver
Which term should the nurse use to describe blood cell production in a client? - Answer
Hematopoiesis
Which information indicates that the nurse has a correct understanding about the
importance of eosinophils? - Answer Eosinophils help control inflammation.
A nurse wants to determine whether a client is making new erythrocytes. Which
laboratory result should the nurse check? - Answer Reticulocyte count
Bone marrow cells that produce platelets. - Answer Megakaryocytes
While checking laboratory results the nurse observes that the reticulocyte count is
elevated in clients with hemorrhagic or hemolytic anemias. How should the nurse
interpret this finding? - Answer Reticulocytes are immature erythrocytes that are
released from bone marrow when circulating erythrocytes are deficient.
,Which information indicates teaching by the nurse was successful for the component
that makes up approximately 7% of plasma? - Answer Proteins
A client has macrocytic anemia. The client is deficient in which nutrient? - Answer
Folate
A nurse is describing a nonnucleated cytoplasmic disk. The nurse is teaching the client
about which cellular component of the blood? - Answer An erythrocyte is a
nonnucleated cytoplasmic disk that contains hemoglobin. A lymphocyte is a
mononuclear immunocyte. Eosinophils and basophils are segmented
polymorphonuclear granulocytes.
A nurse is talking about an organ capable of releasing up to 200 ml of blood into the
circulation to restore blood volume in case of hemorrhage. Which organ is the nurse
describing? - Answer Spleen
The venous sinuses (and the red pulp) can store more than 300 ml of blood. Sudden
reductions in blood pressure cause the sympathetic nervous system to stimulate
constriction of the sinuses and expel as much as 200 ml of blood into the venous
circulation, helping to restore blood volume or pressure in the circulation and
increasing the hematocrit by as much as 4%. The liver has hematologic function,
especially during fetal development, but it does not store blood in a reservoir. The
pancreas releases hormones and digestive enzymes. Bone marrow is a primary
lymphoid organ that does not store blood in a reservoir.
What is another term the nurse could use when talking about a thrombocyte with a
client? - Answer Thrombocyte
Which measurement units will the nurse observe when a client's platelets are
measured? - Answer /mm^3
Which information from the staff indicates teaching by the nurse was successful about
natural killer (NK) cells? - Answer NK cells are large granular lymphocytes that function
in defense against some tumors and viruses.
Which information from the client indicates teaching by the nurse was successful for the
body organ that produces most of the plasma proteins? - Answer Liver
A client has early inflammation. Which illustration will the nurse choose to represent the
predominant granulocytic cells of early inflammation? - Answer Neutrophils
Which term should the nurse use to describe the substance that transports iron in a
client's blood? - Answer transferrin
The laboratory analysis conducted on a child with chronic nasal drainage reveals an
elevated number of eosinophils on a white blood cell differential. Based on this finding,
which is the most likely cause of the nasal drainage? - Answer Allergies
Eosinophils are particularly associated with an increase in number during allergic
, reactions or parasitic infestations.
Neutrophils, not eosinophils, are seen to increase in numbers during bacterial
infections, and neutrophils, not eosinophils, decrease with viral infections.
volatile - Answer Can be eliminated as CO2 gas
Ex. Carbonic Acid ~ Lungs/ Breathing
cell metabolism constantly producing carbon dioxide and carbonic acid
nonvolatile - Answer Can be eliminated by the kidney
Ex. Lactic, sulfuric, phosphoric, others
body acids - Answer end products of protein, carb, and fat metabolism
volatile or nonvolatile
tends toward acidosis
buffering systems - Answer Buffering Pairs of Blood, Lungs and Kidneys
Absorb excess acid (H+) or Hydroxyl (OH-)
occurs in response to change in acid base status
What is normal pH? - Answer 7.35-7.45
Carbonic Acid - Bicarbonate Buffering - Answer Takes place in lung and kidney
Lungs decrease H2CO3 by blowing off, leaving water
Kidneys reabsorb or producing bicarbonate
Compensation vs correction
Protein Buffering - Answer Components present in IC and EC (blood)
Buffering Pairs:
Hb-/HHb—hemoglobin binds with H+
HCO3-/H2CO3--bicarbonate
HPO4-/H2PO4-phosphate
Pr-/HPr-plasma proteins
Renal buffering - Answer (less rapid onset) distal tubule of the kidney regulates ab
balance by secreting H= into the urine and resorbing bicarbonate with maximum acidity
of about 4.4 and 4.7.
