A nurse is preparing to administer a vaccine into the deltoid muscle of a preschooler. Which of the following actions should the nurse take?

Choice A reason: Loss of appetite is not an urgent finding, as it may be caused by various factors, such as nausea, pain, or stress. The nurse should monitor the child's fluid and calorie intake and encourage oral hydration and nutrition. However, loss of appetite does not require immediate reporting to the health care provider.

Choice B reason: Platelet count is not an urgent finding, as it is not given in the text. The nurse should check the child's laboratory results and compare them with the normal ranges for preschoolers. A normal platelet count for children is 150,000 to 450,000 per microliter of blood¹. A low platelet count (thrombocytopenia) may indicate bleeding disorders, infections, or bone marrow problems. A high platelet count (thrombocytosis) may indicate inflammation, infection, or cancer. The nurse should report any abnormal platelet count to the health care provider, but it is not an immediate concern.

Choice C reason: Developmental regression is an urgent finding, as it may indicate a serious neurological problem, such as a brain tumor, infection, or injury. Developmental regression is the loss of previously acquired skills or milestones, such as language, motor, or social skills. The nurse should assess the child's developmental level and report any signs of regression to the health care provider as soon as possible.

Choice D reason: Absolute neutrophil count is an urgent finding, as it may indicate a severe infection or a compromised immune system. Neutrophils are a type of white blood cell that fight bacterial infections. The absolute neutrophil count is the number of neutrophils in a microliter of blood. A normal absolute neutrophil count for children is 1,500 to 8,000 per microliter of blood². A low absolute neutrophil count (neutropenia) may increase the risk of infection and sepsis. A high absolute neutrophil count (neutrophilia) may indicate an acute infection or inflammation. The nurse should report any abnormal absolute neutrophil count to the health care provider immediately.

Choice E reason: Hemoglobin is not an urgent finding, as it is not given in the text. The nurse should check the child's laboratory results and compare them with the normal ranges for preschoolers. Hemoglobin is a protein in red blood cells that carries oxygen. A normal hemoglobin level for children is 11.5 to 15.5 grams per deciliter of blood³. A low hemoglobin level (anemia) may indicate blood loss, iron deficiency, or bone marrow problems. A high hemoglobin level (polycythemia) may indicate dehydration, lung disease, or heart disease. The nurse should report any abnormal hemoglobin level to the health care provider, but it is not an immediate concern.

Choice A reason: Tremors are not a likely finding in a child with hyperglycemia, or high blood glucose. Tremors are more commonly associated with hypoglycemia, or low blood glucose, as the body releases adrenaline to stimulate the release of glucose from the liver. Tremors may also be caused by anxiety, caffeine, or certain medications.

Choice B reason: Shallow respirations are not a likely finding in a child with hyperglycemia, unless the child has developed diabetic ketoacidosis (DKA), a serious complication of diabetes that occurs when the body breaks down fat for energy and produces ketones, which are acidic substances that can cause metabolic acidosis. In DKA, the child may have rapid and deep breathing, also known as Kussmaul respirations, as the body tries to eliminate excess carbon dioxide and acid. However, DKA usually occurs when the blood glucose level is above 300 mg/dL, and the child may also have other signs and symptoms, such as nausea, vomiting, abdominal pain, fruity breath, and confusion.

Choice C reason: Pallor is not a likely finding in a child with hyperglycemia, as the blood flow to the skin is not affected by high blood glucose. Pallor is more commonly associated with anemia, shock, or hypoxia, which are conditions that reduce the oxygen-carrying capacity of the blood or the blood flow to the tissues.

Choice D reason: Lethargy is a likely finding in a child with hyperglycemia, as high blood glucose can cause dehydration, electrolyte imbalance, and impaired brain function. The child may feel tired, weak, and drowsy, and have difficulty concentrating or staying awake. Lethargy may also indicate that the child is at risk of developing DKA, which can lead to coma and death if not treated promptly.
