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
