A mother asks the nurse if her child’s iron deficiency anemia is related to the child’s frequent infections. The nurse responds based on the understanding of which of the following?
- A.
Little is known about iron-deficiency anemia and its relationship to infection in children.
- B.
Children with iron deficiency anemia are more susceptible to infection than are other children.
- C.
Children with iron-deficiency anemia are less susceptible to infection than are other children.
- D.
Children with iron-deficient anemia are equally as susceptible to infection as are other children.
Correct Answer
B. Children with iron deficiency anemia are more susceptible to infection than are other children.Explanation
Children with iron-deficiency anemia are more susceptible to infection because of marked decreases in bone marrow functioning with microcytosis.Rate this question:

Which statements by the mother of a toddler would lead the nurse to suspect that the child has iron-deficiency anemia? Select all that apply.
- A.
“He drinks over 3 cups of milk per day.”
- B.
“I can’t keep enough apple juice in the house; he must drink over 10 ounces per day.”
- C.
“He refuses to eat more than 2 different kinds of vegetables.”

B. “I can’t keep enough apple juice in the house; he must drink over 10 ounces per day.”Explanation

Which of the following foods would the nurse encourage the mother to offer to her child with iron deficiency anemia?
- A.
Rice cereal. whole milk. and yellow vegetables
- B.
Potato. peas. and chicken
- C.
Macaroni. cheese. and ham
- D.
Pudding. green vegetables. and rice
Correct Answer
B. Potato. peas. and chickenExplanation

The physician has ordered several laboratory tests to help diagnose an infant’s bleeding disorder. Which of the following tests. if abnormal. would the nurse interpret as most likely to indicate hemophilia?
- A.
Bleeding time
- B.
Tourniquet test
- C.
Clot retraction test
- D.
Partial thromboplastin time (PTT)
Correct Answer
D. Partial thromboplastin time (PTT)Explanation
PTT measures the activity of thromboplastin. which is dependent on intrinsic clotting factors. In hemophilia. the intrinsic clotting factor VIII (antihemophilic factor) is deficient. resulting in a prolonged PTT.Option A: Bleeding time reflects platelet function.Option B: the tourniquet test measures vasoconstriction and platelet function.Option C: Clot retraction test measures capillary fragility. All of these are unaffected in people with hemophilia.Rate this question:
-
- 5.
Which of the following assessments in a child with hemophilia would lead the nurse to suspect early hemarthrosis?
- A.
Child’s reluctance to move a body part
- B.
Cool. pale. clammy extremity
- C.
Ecchymosis formation around a joint
- D.
Instability of a long bone in passive movement
Correct Answer
A. Child’s reluctance to move a body partExplanation
Bleeding into the joints in the child with hemophilia leads to pain and tenderness. resulting in restricted movement. Therefore. an early sign of hemarthrosis would be the child’s reluctance to move a body part.Option B: If the bleeding into the joint continues. the area becomes hot. swollen. and immobile—not cool. pale. and clammy.Option C: Ecchymosis formation around a joint would be difficult to assess.Option D: Instability of a long bone on passive movement is not associated with joint hemarthrosis.Rate this question:

Because of the risks associated with administration of factor VIII concentrate. the nurse would teach the client’s family to recognize and report which of the following?
- A.
Yellowing of the skin
- B.
Constipation
- C.
Abdominal distention
- D.
Puffiness around the eyes
Correct Answer
A. Yellowing of the skinExplanation
Because factor VIII concentrate is derived from large pools of human plasma. the risk of hepatitis is always present. Clinical manifestations of hepatitis include yellowing of the skin. mucous membranes. and sclera.Options B. C. and D: Use of factor VIII concentrate is not associated with constipation. abdominal distention. or puffiness around the eyes.Rate this question:

A child suspected of having sickle cell disease is seen in a clinic. and laboratory studies are performed. A nurse checks the lab results. knowing that which of the following would be increased in this disease?
- A.
Platelet count
- B.
Hematocrit level
- C.
Reticulocyte count
- D.
Hemoglobin level
Correct Answer
C. Reticulocyte countExplanation
A diagnosis is established based on a complete blood count. examination for sickled red blood cells in the peripheral smear. and hemoglobin electrophoresis. Increased reticulocyte counts occur in children with sickle cell disease because the life span of their sickled red blood cells is shortened.Options A. B. and D: Laboratory studies will show decreased hemoglobin and hematocrit levels and a decreased platelet count. and increased reticulocyte count. and the presence of nucleated red blood cells.Rate this question:
-

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 a precipitating factor. indicates the need for further instructions?
- A.
Infection
- B.
Trauma
- C.
Fluid overload
- D.
Stress
Correct Answer
C. Fluid overloadExplanation
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 ½ to 2 times the daily requirement to prevent dehydration.Rate this question:

Laboratory studies are performed for a child suspected of having iron deficiency anemia. The nurse reviews the laboratory results. knowing that which of the following results would indicate this type of anemia?
- A.
An elevated hemoglobin level
- B.
A decreased reticulocyte count
- C.
An elevated RBC count
- D.
Red blood cells that are microcytic and hypochromic
Correct Answer
D. Red blood cells that are microcytic and hypochromicExplanation
The results of a CBC in children with iron deficiency anemia will show decreased hemoglobin levels and microcytic and hypochromic red blood cells. The red blood cell count is decreased. The reticulocyte count is usually normal or slightly elevated.Rate this question:

A pediatric nurse health educator provides a teaching session to the nursing staff regarding hemophilia. Which of the following information regarding this disorder would the nurse plan to include in the discussion?
- A.
Hemophilia is a Y linked hereditary disorder
- B.
Males inherit hemophilia from their fathers
- C.
Females inherit hemophilia from their mothers
- D.
Hemophilia A results from a deficiency of factor VIII
Correct Answer
D. Hemophilia A results from a deficiency of factor VIIIExplanation
Hemophilia A results from a deficiency of factor VIII. Hemophilia B (Christmas disease) is a deficiency of factor IX.Option A: Hemophilia is inherited in a recessive manner via a genetic defect on the X-chromosome.Options B and C: Males inherit hemophilia from their mothers. and females inherit the carrier status from their fathers.Rate this question:
