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","B","C","D"]
Explanation
Choice A reason: This is a finding that the nurse should report to the provider. A pressure dressing is applied to the site of the catheter insertion to prevent bleeding and hematoma formation. If the dressing is saturated with bloody drainage, it indicates that the bleeding is not controlled and may lead to hemorrhage or infection.
Choice B reason: This is a finding that the nurse should report to the provider. Pulses of the extremity where the catheter was inserted should be equal to or stronger than the other extremity. If the pulses are diminished, it indicates that there is impaired blood flow to the extremity, which may be caused by arterial occlusion, thrombosis, or vasospasm.
Choice C reason: This is a finding that the nurse should report to the provider. The color and temperature of the extremity where the catheter was inserted should be similar to the other extremity. If the extremity is cool and pale, it indicates that there is inadequate perfusion to the extremity, which may be caused by the same factors as the diminished pulses.
Choice D reason: This is a finding that the nurse should report to the provider. Pain is an indicator of tissue damage or inflammation. The adolescent should have minimal or no pain after the procedure, as the site is numbed with local anesthesia. If the pain is present or increases, it indicates that there is a complication, such as bleeding, infection, or nerve injury.
Choice E reason: This is not a finding that the nurse should report to the provider. The apical pulse is the heart rate measured at the apex of the heart. It is a routine vital sign that the nurse should monitor after the procedure, but it is not a sign of a complication unless it is abnormal, such as too fast, too slow, or irregular. The nurse should compare the apical pulse with the baseline and the expected range for the adolescent's age and condition.
Correct Answer is ["B"]
Explanation
Choice A reason: Polyuria, or excessive urination, is not a sign of low blood glucose level, but of high blood glucose level. It is caused by osmotic diuresis, which occurs when the kidneys try to flush out the excess glucose from the blood.
Choice B reason: Tachycardia, or fast heart rate, is a sign of low blood glucose level. It is caused by the activation of the sympathetic nervous system, which releases adrenaline and other hormones to increase the blood glucose level and stimulate the heart.
Choice C reason: Dry, flushed skin is not a sign of low blood glucose level, but of high blood glucose level. It is caused by dehydration, which occurs when the body loses fluid due to polyuria and increased thirst.
Choice D reason: Deep, rapid respirations are not a sign of low blood glucose level, but of diabetic ketoacidosis, a complication of high blood glucose level. It is caused by the accumulation of ketones, which are acidic substances produced when the body breaks down fat for energy due to lack of insulin.
Choice E reason: Hunger is a sign of low blood glucose level. It is caused by the lack of glucose in the cells, which are the main source of energy for the body. The brain signals the body to eat more to raise the blood glucose level.
