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 A
Explanation
Choice A reason: This is a contraindication for the MMR immunization, which is a live attenuated vaccine. A child who has a congenital immunodeficiency may not be able to mount an adequate immune response to the vaccine and may be at risk of developing the diseases from the vaccine.
Choice B reason: This is not a contraindication for the MMR immunization. A mild fever after a previous immunization is not a sign of an allergic reaction or a serious adverse effect. The child can still receive the MMR immunization as long as they do not have a moderate or severe illness.
Choice C reason: This is not a contraindication for the MMR immunization. Taking antibiotics for otitis media does not interfere with the effectiveness or safety of the vaccine. The child can still receive the MMR immunization as long as they do not have a moderate or severe illness.
Choice D reason: This is not a contraindication for the MMR immunization. A mild cough and a low-grade fever are not signs of a moderate or severe illness that would prevent the child from receiving the vaccine. The child can still receive the MMR immunization as long as they do not have any other contraindications.
Correct Answer is A
Explanation
Choice A reason: This is the most likely source of the child's infection. Rheumatic fever is a complication of an untreated or poorly treated streptococcal infection, such as strep throat or scarlet fever. It usually occurs 2 to 4 weeks after the initial infection and causes inflammation of the heart, joints, skin, and nervous system. The nurse should ask the parent if the sibling was tested and treated for strep throat, and if the child was exposed to the sibling.
Choice B reason: This is not a likely source of the child's infection. Chickenpox is caused by the varicella-zoster virus, not by streptococci. It is a highly contagious disease that causes a blister-like rash, itching, fever, and fatigue. It does not cause rheumatic fever, but it can lead to other complications, such as bacterial skin infections, pneumonia, or encephalitis.
Choice C reason: This is not a likely source of the child's infection. Fifth disease is caused by the parvovirus B19, not by streptococci. It is a mild illness that causes a distinctive red rash on the face, body, and limbs, as well as fever, headache, and sore throat. It does not cause rheumatic fever, but it can affect the production of red blood cells and cause anemia in some people.
Choice D reason: This is not a likely source of the child's infection. Gastritis is the inflammation of the stomach lining, which can be caused by various factors, such as bacteria, viruses, medications, alcohol, or stress. It is not caused by streptococci, nor does it cause rheumatic fever. It can cause symptoms such as abdominal pain, nausea, vomiting, and loss of appetite.
