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.
