The nurse knows that an important contraindication for valproic acid use is:

Choice A rationale

Soft stools and flatus indicate proper gastrointestinal function, suggesting tolerance to feeding. With no adverse symptoms, it is not scientifically valid to hold enteral feeding based on these findings alone.

Choice B rationale

Diluting medications with D5W and flushing ensures patency but does not address potential complications like abdominal distention or bowel sounds. RLQ tenderness must first be evaluated for safety.

Choice C rationale

Abdomen distention with hypoactive bowel sounds and RLQ tenderness suggests possible ileus or bowel obstruction. Discussing this condition with the prescriber ensures safe feeding practices and prevents worsening complications.

Choice D rationale

Residual formula checks are relevant for gastric, not jejunostomy, feeding. Scientific practice discourages assessing residual in jejunostomy feeding as the tube bypasses the stomach.

Choice A rationale

Subarachnoid hemorrhage is less likely given the sudden decrease in consciousness. This type of injury typically results in severe headache or focal neurological deficits, not rapid mental decline.

Choice B rationale

Diffuse axonal injury usually presents with persistent unconsciousness rather than sudden deterioration. It results from widespread shearing forces and is less likely with the reported history.

Choice C rationale

Epidural hematoma often presents with a lucid interval followed by sudden neurological decline, as described in this case. Rapid accumulation of blood between the dura and skull can compress brain tissue.

Choice D rationale

Subdural hematoma tends to cause gradual neurological deterioration rather than a sudden decrease in Glasgow Coma Scale. This occurs due to slower venous bleeding. .
