Which diagnostic test is the most definitive test used to detect meningitis?
CBC
Urinalysis
CT scan
Lumbar puncture
The Correct Answer is D
A. CBC: A CBC can indicate infection (elevated white blood cell count), but it is not specific for meningitis.
B. Urinalysis: Urinalysis is not relevant for diagnosing meningitis.
C. CT scan: A CT scan can detect complications like increased intracranial pressure but does not diagnose meningitis directly.
D. Lumbar puncture: A lumbar puncture allows direct analysis of CSF for glucose, protein, white blood cells, and organisms, which is definitive for diagnosing meningitis.

Correct Answer is D
Explanation
A. Preschool children experience fear related to the disease process. While preschool children may fear pain or separation, this statement does not directly address their perception of death.
B. Preschool children understand death completely. Preschool children do not fully understand the permanence of death; this comprehension develops later.
C. Preschool children have no concept of death. Preschoolers have some concept of death but often see it as temporary or reversible.
D. Preschool children perceive death as temporary. Preschool-aged children often view death as temporary, like sleeping, due to their limited understanding of its finality.
Correct Answer is B
Explanation
A. Restrain the toddler for 1 hr after the procedure: Restraint is not appropriate post-procedure. The child should be monitored for complications but not physically restrained unless medically necessary.
B. Place the toddler in a side-lying, knee-chest position: This position flexes the spine and opens the spaces between the vertebrae, allowing for easier access to the subarachnoid space for the lumbar puncture.
C. Ask another nurse to assist with holding the toddler in a prone position: The prone position is incorrect for lumbar punctures. The side-lying, knee-chest position is standard.
D. Swaddle the toddler in a warm blanket: Swaddling may comfort the toddler but does not facilitate the lumbar puncture.
