A nurse is caring for an adolescent who was brought to the emergency department (ED) with a high fever, headache, and neck stiffness. The nurse reviews the adolescent's cerebrospinal fluid (CSF) analysis results and notes the following:
- WBC count 300 cells/microliter (normal range: 0 to 10 cells/microliter)
- Protein 45 mg/dL (normal range: 15 to 45 mg/dL)
- Glucose 40 mg/dL (normal range: 50 to 75 mg/dL)
- Color Turbid (normal: clear and colorless)
The nurse should suspect that the adolescent has which of the following conditions?
Bacterial meningitis.
Viral meningitis.
Encephalitis.
Brain abscess.
The Correct Answer is A
Choice A reason: Bacterial meningitis is a probable condition, as it is an infection of the membranes that cover the brain and spinal cord, caused by various bacteria, such as Streptococcus pneumoniae, Neisseria meningitidis, or Haemophilus influenzae. The adolescent has many signs and symptoms of bacterial meningitis, such as fever, headache, and neck stiffness.

Choice B reason: Viral meningitis is not a likely condition, as it is an infection of the membranes that cover the brain and spinal cord, caused by various viruses, such as enteroviruses, herpes simplex virus, or mumps virus. The adolescent has some signs and symptoms of viral meningitis, such as fever, headache, and neck stiffness, but they are usually less severe than bacterial meningitis.
Choice C reason: Encephalitis is not a probable condition, as it is an inflammation of the brain tissue, usually caused by viral infections, such as herpes simplex virus, West Nile virus, or rabies virus. The adolescent has some signs and symptoms of encephalitis, such as fever, headache, and altered mental status, but they are usually accompanied by focal neurological deficits, such as seizures, paralysis, or cranial nerve palsies.
Choice D reason: Brain abscess is not a definite condition, as it is a collection of pus within the brain tissue, usually caused by bacterial infections that spread from other parts of the body, such as the ear, sinus, or lung. The adolescent has some signs and symptoms of brain abscess, such as fever, headache, and altered mental status, but they are usually accompanied by focal neurological deficits, such as seizures, paralysis, or cranial nerve palsies.

Correct Answer is ["C","D"]
Explanation
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.
Correct Answer is B
Explanation
Choice A reason: The onset of low blood glucose, or hypoglycemia, usually occurs rapidly and can be triggered by skipping meals, exercising too much, or taking too much insulin. The nurse should teach the parents to recognize the signs and symptoms of hypoglycemia and how to treat it promptly.
Choice B reason: Feeling shaky is one of the common signs of low blood glucose, along with hunger, sweating, dizziness, confusion, and irritability. The nurse should teach the parents to check the child's blood glucose level and give him a fast-acting carbohydrate, such as juice, candy, or glucose tablets, if it is below 70 mg/dL.
Choice C reason: Sweating can occur with low blood glucose, not high blood glucose, or hyperglycemia. Hyperglycemia can cause symptoms such as thirst, frequent urination, dry mouth, blurred vision, and fatigue. The nurse should teach the parents to monitor the child's blood glucose level regularly and adjust his insulin dose, diet, and exercise accordingly.
Choice D reason: Nausea and vomiting can occur with high blood glucose, especially if it leads to diabetic ketoacidosis, a serious complication of diabetes. Diabetic ketoacidosis can also cause abdominal pain, fruity breath, rapid breathing, and coma. The nurse should teach the parents to seek emergency medical attention if the child has these symptoms.
