A nurse is caring for a client who has a white blood cell (WBC) count of 15,000/mm3. Which of the following actions should the nurse take?

Choice A reason: Tetany is not a typical finding in an infant who is dehydrated. Tetany is a condition where the muscles contract involuntarily and cause spasms or cramps. It is usually caused by low calcium levels or alkalosis, not dehydration.

Choice B reason: Slow, bounding pulse is not a typical finding in an infant who is dehydrated. A slow, bounding pulse may indicate increased intracranial pressure or heart failure, not dehydration. A fast, weak pulse is more likely to occur in an infant who is dehydrated.

Choice C reason: Decreased temperature is not a typical finding in an infant who is dehydrated. A decreased temperature may indicate hypothermia or sepsis, not dehydration. A normal or slightly elevated temperature is more likely to occur in an infant who is dehydrated.

Choice D reason: Irritability is a typical finding in an infant who is dehydrated. Irritability indicates that the infant is uncomfortable and thirsty. It may also be a sign of cerebral dehydration, which can affect the infant's mental status and behavior.

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.
