Question 1

A 9-year-old with severe TBI has an ICP of 28 mmHg and MAP of 70 mmHg. What is the cerebral perfusion pressure (CPP)?

Accepted Answer

42 mmHg

Answer

CPP = MAP − ICP; therefore 70 − 28 = 42 mmHg, which is below the recommended minimum of 50–60 mmHg in pediatric TBI.

Question 2

Which clinical finding is the EARLIEST sign of increasing intracranial pressure in a child?

Accepted Answer

Altered level of consciousness and irritability

Answer

Altered LOC and irritability are early signs of elevated ICP; Cushing's triad and fixed pupils are late, often pre-terminal findings.

Question 3

A 5-year-old with bacterial meningitis develops a generalized tonic-clonic seizure lasting 4 minutes. Which drug should be administered FIRST?

Accepted Answer

Lorazepam 0.1 mg/kg IV

Answer

Benzodiazepines (lorazepam IV) are the first-line treatment for acute seizures per PALS and most pediatric status epilepticus guidelines.

Question 4

A 12-year-old after a near-drowning has a GCS of 6. Which GCS subscores produce this total?

Accepted Answer

Eye 2, Verbal 2, Motor 2

Answer

Eye 2 + Verbal 2 + Motor 2 = 6; any combination totaling 6 is valid, but 2+2+2 is a common testing scenario reflecting severe impairment in all domains.

Question 5

Which intervention is CONTRAINDICATED in a child with suspected increased intracranial pressure and an intact airway?

Accepted Answer

Performing a lumbar puncture immediately

Answer

Lumbar puncture is contraindicated with elevated ICP because sudden CSF drainage can cause transtentorial herniation.
