A nurse is admitting an 8-year-old child to the pediatric unit.

A nurse is reviewing the child's electronic medical record (EMR). Which of the following findings should the nurse identify as requiring immediate follow-up? Select the 5 findings that require immediate follow-up.

A. Obtain a vertical height measurement: School-age children are measured standing upright to accurately assess linear growth and compare it with age-appropriate growth charts. Vertical height measurement reflects skeletal growth and is a key component of routine physical assessment in this age group.

B. Remove the child's eyeglasses before performing a visual acuity exam: Visual acuity testing should be performed with the child wearing corrective lenses if they are normally used. Removing eyeglasses would not reflect the child’s functional vision and may lead to inaccurate assessment findings.

C. Inspect the ear by pulling the pinna down and back: For school-age children and adults, the pinna should be pulled up and back to straighten the ear canal. Pulling the pinna down and back is appropriate only for children under 3 years of age.

D. Observe abdominal movement to determine the respiratory rate: Respiratory rate in school-age children is best assessed by observing chest movement. Abdominal observation is more appropriate in infants, who primarily use diaphragmatic breathing.

Rationale for correct choices

• Preparing for a lumbar puncture: The child presents with fever, headache, nausea, irritability, lethargy, and nuchal rigidity, which are classic signs of meningitis or central nervous system infection. A lumbar puncture is the definitive diagnostic procedure to evaluate cerebrospinal fluid for infection, inflammation, or other abnormalities.

• Neurological findings: The neurological signs of lethargy, irritability, headache, and nuchal rigidity indicate possible central nervous system involvement. These findings guide the provider to order a lumbar puncture to confirm or rule out meningitis or other neurologic pathology. Early recognition and intervention are essential to prevent complications.

Rationale for incorrect choices

• Administering potassium chloride|: The child’s potassium level is 3.8 mEq/L, which is within normal limits (3.4–4.7 mEq/L). There is no indication for potassium supplementation at this time, making this intervention unnecessary.

• Administering acyclovir: Acyclovir is indicated for suspected viral infections such as herpes simplex encephalitis. While viral etiology may be considered later, the immediate priority is confirming meningitis through lumbar puncture rather than empiric antiviral therapy.

• Initiating airborne precautions: Airborne precautions are required for infections like measles, varicella, or tuberculosis. Meningitis is typically spread via droplet transmission, not airborne, so droplet precautions would be more appropriate if bacterial meningitis is suspected.

• Increasing environmental stimuli: The child exhibits irritability and lethargy; increasing stimuli could worsen agitation and interfere with assessment. The focus should be on providing a calm environment to safely evaluate neurological status.

• Lymph node findings: While lymphadenopathy may be relevant in some infections, the child’s current presentation of nuchal rigidity and neurologic symptoms takes priority for evaluation of CNS infection.

• Potassium level: Potassium is within normal limits, and there are no cardiac or metabolic indications for immediate intervention.

• Pain level: Although the child reports headache (pain 7/10), the neurological findings and risk for meningitis take precedence over pain management when anticipating a lumbar puncture.

• WBC: The WBC is elevated (14,000/mm³), which supports infection, but it alone does not dictate the need for a lumbar puncture. Neurological findings are the key indicator for this procedure.
