The nurse knows that an important contraindication for valproic acid use is:
Bipolar disorder.
Pre-existing liver disease.
Asthma.
Migraine headaches.
The Correct Answer is B
Choice A rationale
Bipolar disorder is an approved indication for valproic acid use. It helps stabilize mood swings, particularly mania, making it a suitable treatment rather than a contraindication.
Choice B rationale
Pre-existing liver disease contraindicates valproic acid because it increases the risk of hepatic toxicity and liver failure. Liver function must be closely monitored in all patients receiving this drug.
Choice C rationale
Asthma is not affected by valproic acid use as the drug targets neurological pathways and does not impact respiratory or bronchial systems significantly.
Choice D rationale
Valproic acid is used to treat migraines and seizures. It prevents the occurrence of severe headaches through stabilization of neuronal activity, making this an appropriate rather than contraindicated use. .

Step 1 is (225 mcg ÷ 1000 mcg) × 0.50 tablets.
Answer is 0.1 tablets.
Correct Answer is A
Explanation
Choice A rationale
Hemiparesis on the right side and ataxia are common manifestations of left-sided stroke, where the motor cortex affecting the contralateral side is impaired, leading to muscle weakness and coordination loss.
Choice B rationale
Spasticity of the left arm suggests motor impairment on the ipsilateral side, which is inconsistent with the nature of left-sided strokes affecting the contralateral side. Apraxia lacks relation to motor loss here.
Choice C rationale
Impulsive behavior and hostility are more indicative of frontal lobe involvement, not motor loss secondary to left-sided strokes. These behaviors do not represent motor manifestations.
Choice D rationale
Visual defects like homonymous hemianopia and diplopia may occur in stroke but are not direct indicators of motor loss. They relate to occipital lobe or optic pathway damage.
