QUESTIONS AND ANSWERS 100% CORRECT
◉ A newborn baby has a clotting disorder that results in her body
being unable to produce thrombin. Which of the following phases of
platelet degranulation would be impossible?
A. Subendothelial exposure
B. Adhesion
C. Activation
D. Aggregation Answer: aggregation
◉ While checking lab results, the nurse remembers the normal
leukocyte count is: Answer: 5,000-10,000/mm3
◉ When a staff member asks how erythrocytes can carry oxygen,
which of the following properties should the nurse describe that
allow erythrocytes to function as gas carriers? (Select all that apply.)
Answer: - Biconcavity
- Reversible deformability
,◉ A nurse is caring for an elderly patient. Which of the following are
true regarding the hematological system and aging? (Select all that
apply.) Answer: Total serum iron is decreased
Total iron-binding capacity is decreased
Intestinal iron absorption is decreased
◉ When an aide asks a nurse how many oxygen molecules can
hemoglobin carry, what is the nurse's best response? Hemoglobin
molecules carry _____ oxygen molecules. Answer: 4 (four)
◉ A patient's anemia is described as having erythrocytes that
demonstrate anisocytosis. The nurse would recognize the
erythrocytes would be: Answer: Able to assume various shapes
◉ A newborn is diagnosed with congenital intrinsic factor
deficiency. Which of the following types of anemia will the nurse see
documented on the chart? Answer: pernicious anemia
◉ When a nurse is reviewing lab results and notices that the
erythrocytes contain an abnormally low concentration of
hemoglobin, the nurse calls these erythrocytes: Answer:
hypochromic
,◉ A 5-year-old male was diagnosed with normocytic-normochromic
anemia. Which of the following anemias does the nurse suspect the
patient has? Answer: hemolytic anemia
◉ After initial compensation, what hemodynamic change should the
nurse monitor for in a patient who has a reduction in the number of
circulating erythrocytes? Answer: Hyperdynamic circulatory state
◉ A 25-year-old female has a heavy menses during which she loses a
profuse amount of blood. Which of the following adaptations should
the nurse expect? Answer: peripheral vasoconstriction
◉ A 60-year-old female emphysema patient experiences a rapid and
pounding heart, dizziness, and fatigue with exertion. Which of the
following respiratory assessment findings indicate the respiratory
system is compensating for the increased oxygen demand? Answer:
increased rate and depth of breathing
◉ A 2-year-old malnourished child has vitamin B12 and folate
deficiencies. A blood smear suggests the deficiency is macrocytic
and normochromic. The nurse would expect the hemoglobin to be:
Answer: normal
◉ A 45-year-old male is diagnosed with macrocytic, normochromic
anemia. The nurse suspects the most likely cause of this condition is:
Answer: Defective DNA synthesis
, These anemias are the result of ineffective erythrocyte
deoxyribonucleic acid (DNA) synthesis.
◉ When a patient wants to know why vitamin B12 and folate
deficiencies cause anemia, how should the nurse respond? Answer:
Red blood cells have a shorter life span
These deficiencies lead to defective erythrocytes that die
prematurely, which decreases their numbers in the circulation,
causing anemia
◉ A 20-year-old female undergoes lab testing for anemia. Results
show high iron, bilirubin, and transferrin and low hemoglobin and
hematocrit. Which of the following is the most likely diagnosis to be
documented on the chart? Answer: Sideroblastic anemia
Individuals with sideroblastic anemia may show signs of iron
overload (hemosiderosis), including mild to moderate enlargement
of the liver (hepatomegaly) and spleen (splenomegaly).
◉ A 35-year-old female is diagnosed with vitamin B12 deficiency
anemia (pernicious anemia). How should the nurse respond when
the patient asks what causes pernicious anemia? A decrease in ______
is the most likely cause. Answer: Intrinsic factor
