Which age group is primarily suitable for using the FACES pain scale?

Analyzing cerebrospinal fluid changes in meningitis requires knowledge of pathophysiology and microbial metabolism. One must understand how pathogens cross the blood-brain barrier and the metabolic requirements of bacteria compared to normal physiological states in the central nervous system during acute infection.

Choice A rationale

Liver glucose production, or gluconeogenesis, is typically increased during the stress of systemic infection due to cortisol and glucagon. A decrease in CSF glucose is a localized metabolic phenomenon within the subarachnoid space rather than hepatic failure.

Choice B rationale

Bacteria and leukocytes in the CSF consume glucose as a primary energy source for metabolism and replication. Normal CSF glucose is 40 to 70 mg/dL, but in bacterial meningitis, this level drops significantly as pathogens utilize it.

Choice C rationale

While the blood-brain barrier is affected during inflammation, it generally becomes more permeable, not less. The low glucose level is not due to a blockage of entry but rather the rapid consumption of glucose once it enters.

Choice D rationale

While systemic glucose uptake might change during illness, it does not explain the specific drop in CSF levels relative to blood levels. The hallmark of bacterial meningitis is the decreased ratio of CSF glucose to serum glucose..

Patient safety during medication administration is rooted in the prevention of medical errors. Applying the six rights of medication administration requires reliable verification methods. Understanding the limitations of pediatric clients necessitates using standardized, multiple identifiers to ensure the correct recipient.

Choice A rationale

Checking only the wristband is insufficient because errors in labeling or transcription can occur. Using a single point of verification increases the risk of administering medication to the wrong client, especially in high-volume or high-stress pediatric environments.

Choice B rationale

Pediatric clients may be developmentally unable to provide accurate information or may answer to a different name if they are confused or playful. Relying solely on the child's verbal response is not a safe or standardized practice.

Choice C rationale

Utilizing two distinct identifiers is the gold standard for patient safety. Comparing the name and date of birth (DOB) on the medication record with the client's wristband ensures the highest level of accuracy and error prevention.

Choice D rationale

While parents are valuable resources, the nurse has a professional responsibility to verify identifiers against the official medical record. Parental confirmation should supplement, not replace, the systematic checking of the client's hospital identification band and record..
