The nursing instructor is teaching a student how to administer iron dextran injections to a child with severe anemia. Which instruction does the nurse give after the student administers the injection?

"Do not massage the injection site." Rational The nursing instructor tells the student to avoid massaging the injection site to minimize skin staining and irritation. The nurse places the patient in an appropriate position before administering the injection. It is necessary to rotate sites because of the potential for tissue damage. The nurse disposes of the syringe safely after administering the medication to avoid stick injuries.

The parent of a 6-month-old infant asks the nurse about the food that can be included in the child's diet. What does the nurse suggest?

"Include cereals in the diet." Rational Cereals are the first semisolid foods that should be given to an infant at 6 months of age. This helps the infant accept food other than milk and prevents the risk for anemia. The nurse does not advise feeding only breast milk because it may induce nutritional anemia. Cow's milk puts the child at risk for gastrointestinal blood loss because of the presence of heat-labile protein in the milk. Carrots and peas are solid foods that are not digested by the infants at 6 months.

The nurse is reviewing the laboratory results of a 1-year-old child who has been diagnosed with sickle cell anemia (SCA) during infancy and is now presenting with symptoms of the disease.

2 to 3

The parents of a child taking oral iron supplements report that the child's stools are a tarry green color. What is the best response the nurse provides to the parents?

"Tarry green color is expected with oral iron supplements."

The medication should be stopped immediately if there are any allergic symptoms or toxicity. Tarry green stools is not a side effect of taking oral iron supplements.

48

The nurse finds that a child is pale, gets easily fatigued, and has lack of energy. The nurse asks the parents to get a complete blood count (CBC) test. What does the nurse suspect from these symptoms?

Anemia Rational: Paleness, fatigue, and lack of energy are the symptoms of anemia that can be confirmed after a CBC test. Splenic sequestration is a symptom of sickle cell anemia, which causes an enlarged spleen. Chest syndrome is a symptom of sickle cell anemia with signs of hypoxia, chest pain, fever, cough, and wheezing.

The nurse is assessing a child with immune thrombocytopenia (ITP). The nurse observes that there is no active bleeding in the child. Which medications does the nurse expect in the child's prescription?

Chronic transfusion therapy

Which statement best describes the onset of clinical manifestations in thalassemia major?

Clinical manifestations may be insidious and not recognized until early toddlerhood. Rational Clinical manifestations in thalassemia major are not recognized until late infancy or early toddlerhood. They may appear well before adolescence, young adulthood, and middle adulthood.

Which condition in a child indicates a deficiency of one of the factors (proteins) necessary for blood coagulation?

Hemophilia Rational Hemophilia is a group of bleeding disorders in which there is a deficiency of one of the clotting factors necessary for blood coagulation. Aplastic anemia is characterized by anemia, leukopenia, and decreased platelet count. Sickle cell anemia occurs when normal hemoglobin is replaced by abnormal hemoglobin. Apheresis refers to the process of removing blood from a patient, usually before stem cell transplantation or chemotherapy.

_________________________ causes bleeding in the subcutaneous tissue, intramuscular tissue, and the joint space because of a lack of clotting factor. The disease gets worse if antihemophilic factor is less in the blood. Patients with____________________ have two factors (vascular influence and platelets) required for blood coagulation; hence, they bleed for longer periods but not at a faster rate.

Hemophilia A

The nurse is educating the parents of a child about the symptoms that would indicate sickle cell anemia. Which symptoms does the nurse describe? Select all that apply.

Hypoxia Chest pain Painful joints Big and swollen spleen

Which symptom is seen in a child with disseminated intravascular coagulation (DIC)?

Increased tendency to bleed Rational: A child with DIC has an increased tendency to bleed as a result of excess thrombin and destruction of platelets. Rickettsial infections may sometimes cause DIC. It is not a symptom of DIC.

The school nurse is discussing prevention of acquired immunodeficiency syndrome with some adolescents. In the discussion, what should the nurse include?

Intravenous drug users should not share needles.

Stavudine

The nurse suspects that a child is having an adverse reaction to a blood transfusion. What should be the first action by the nurse?

Stop transfusion and maintain a patent intravenous line with normal saline and new tubing Rational Stopping the transfusion is the priority nursing action. If an adverse reaction is occurring, it is essential to minimize the amount of blood that is infused. Notifying the physician and taking vital signs should be performed after the blood transfusion is stopped and infusion of normal saline has begun. Blood should not be diluted; it should be returned to the blood bank if an adverse reaction has occurred.

What is the most common manifestation of severe combined immunodeficiency disease (SCID)?

Susceptibility to infection Rational Susceptibility to infection early in life is the most common manifestation of SCID. Bloody stools, chronic nosebleeds, and skin rashes are not as common.

how to administer blood

The nurse takes vital signs before the blood transfusion to establish baseline data for intratransfusion. Vital signs are taken hourly while the blood is infusing and taken post-transfusion to check for any adverse reactions. The nurse administers the first 50 mL of the blood volume slowly to prevent any abnormalities in the blood pressure and assess for adverse reactions. If there is any reaction in the child, the nurse stops the transfusion, takes vital signs, and maintains a patent IV line with normal saline and new tubing. The nurse then informs the primary health care provider. The nurse uses an appropriate filter for administering blood to eliminate any particles in the blood. The nurse uses the blood within 30 minutes of its arrival from the blood bank so that the blood properties do not change.

The nurse prepares to administer a blood transfusion to a 7-year-old child with severe anemia with mild tissue hypoxia. The prescription reads that packed red blood cells (RBCs) are to be administered at 4 mL/kg. Why does this cause the nurse to contact the prescriber?
