Hematology Actual Questions and Correct Answers
Q1
A child is suspected of having sickle cell disease is seen in a clinic, and laboratory studies are
performed. A nurse checks the laboratory results, knowing that which of the following would be
increased in this disease? platelet count hematocrit level reticulocyte count Hemoglobin level
Answer: 3 A diagnosis is established based on a complete blood count, examination for
sickled red blood cells in the peripheral smear, and hemoglobin electrophoresis.
Laboratory studies will show decreased hemoglobin and hematocrit levels and a
decreased platelet count, an INCREASED reticulocyte count and the presence of
nucleated red blood cells. Increased reticulocyte counts occur in children with sickle
cell disease because the life span of their sickled red blood cells is shortened.
Q2
A pediatric nursing instructor asks a nursing student to describe the cause of the clinical
manifestations that occur in sickle cell disease. The student responds correctly by telling the
instructor that Sickled cells increase the blood flow through the body and cause a great deal of
pain. sickled cells mix with the unsickled cells and cause the immune system to become
depressed. bone marrow depression occurs because of the development of sickled cells.
Answer: Sickled cells increase the blood flow through the body and cause a great deal
of pain.
Q3
A clinic nurse instructs the mother of a child with sickle cell disease about the precipitating
factors related to pain crisis. Which of the following, if identified by the mother as e
precipitating factor, indicates the need for further instructions? infection trauma fluid overload
stress
Answer: 3
Q4
Pain crisis may be precipitated by infection, dehydration, hypoxia, trauma, or physical or
emotional stress. THe mother of a child with sickle cell disease should encourage fluid intake of
1.5-2 times the daily requirement to prevent dehydration! A client with anemia has a nursing
diagnosis of activity intolerance. Which of the following interventions will the nurse plan for this
client? Promote active and passive range-of-motion activities. Space activities and plan rest
periods. Teach the client to change position slowly to prevent dizziness. Teach the client the
basics of good nutrition.
Answer: Space activities and plan rest periods. Rationale:
, Q5
The client with activity intolerance tires easily, so it is best for the nurse to plan care and
activities around periods of rest. Teaching good nutrition will not help the client to be less tired.
Promoting range of motion does not address the issue of fatigue, nor does teaching the client to
change position slowly. The nurse is teaching a group of parents whose children have sickle cell
anemia. When a parent asks the cause of the symptoms, the nurse responds with which of the
following? "Sickled cells clump in the smaller blood vessels and obstruct blood flow." "Sickled
cells cause bone marrow depression."
Answer: "Sickled cells clump in the smaller blood vessels and obstruct blood flow."

Q7
The nurse is instructing the mother of a child with sickle cell disease about the risk factors for
precipitation of sickle cell crisis. Which of the following, if identified by the mother as a
precipitating factor, indicates the need for further teaching? Stress Trauma Fluid overload
4.Infection
Answer: Stress
Q8
The nurse is admitting a 7-year-old client who is experiencing sickle cell crisis and plans care
based on which of the following nursing diagnoses? Risk for Bleeding Ineffective Airway
Clearance Risk for Constipation Delayed Growth and Development
Answer: Risk for Bleeding
Q9
3.Cardiovascular system 4.Gastrointestinal system
Answer: 3.Cardiovascular system 4.Gastrointestinal system
Q10
The nurse is planning care for a child who is newly diagnosed with sickle cell disease. Which of
the following would the nurse plan with the family to best promote the child's growth and
development? Renal health plan 2.Emergency care in the school setting Nutritional support
during hospitalizations Individualized school health plan
Answer: Renal health plan 2.Emergency care in the school setting
