The nurse is caring for a client who receives a prescription for valproic acid in which the maximum safe dosage is 60 mg/kg/day.

How many mg/day is the maximum safe dosage for a client who weighs 176 pounds? (Enter numerical value only.).

Choice A rationale:

Checking the client's temperature is important for assessing the client's condition, but it is not a priority before administering penicillin G IV for meningitis.

Choice B rationale:

Assessing the client's level of consciousness is essential for monitoring neurological status, but it is not the highest priority action before administering penicillin G IV for meningitis.

Choice C rationale:

Asking the client about any history of allergies is important for assessing potential allergic reactions to medications. However, the most critical action before administering penicillin G IV for meningitis is to obtain a blood sample for culture and sensitivity. This action helps identify the causative organism and guides appropriate antibiotic therapy, as meningitis can be life-threatening and requires prompt treatment.

Choice D rationale:

Obtaining a blood sample for culture and sensitivity is the highest priority action before administering penicillin G IV for meningitis. Identifying the specific pathogen responsible for the infection is crucial for selecting the most effective antibiotic therapy and preventing complications.

Choice A rationale:

Altered consciousness within the first 24 hours after injury is not indicative of a developing epidural hematoma. An epidural hematoma typically manifests as a lucid interval followed by a rapid deterioration in consciousness hours after the injury.

Choice B rationale:

Cushing reflex (increased blood pressure, bradycardia, and irregular respirations) and cerebral edema after 24 hours are characteristic signs of a developing epidural hematoma. This occurs due to the accumulation of blood between the dura mater and the skull, leading to increased intracranial pressure.

Choice C rationale:

Headache and pupillary changes 48 hours after head injury are not specific signs of an epidural hematoma. These symptoms may indicate various other neurological conditions or complications.

Choice D rationale:

Fever, nuchal rigidity, and opisthotonos within hours are suggestive of meningitis rather than an epidural hematoma. These symptoms are not typical of epidural hematomas, which primarily involve alterations in consciousness and increased intracranial pressure.
