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

Bipolar disorder.

Pre-existing liver disease.

Asthma.

Migraine headaches.

Answer and Explanation

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. .

Correct Answer is A

Explanation

Choice A rationale

Vigorous coughing or nose blowing increases pressure in the middle ear, potentially dislodging the stapes prosthesis, interfering with healing, and increasing risk of complications like vertigo or auditory damage.

Choice B rationale

Packing with dry dressing is contraindicated because it may trap moisture and increase infection risk. If drainage occurs, sterile measures are taken to assess and manage infection without creating ideal conditions for pathogens.

Choice C rationale

Irrigation of the ear canal risks introducing pathogens or disrupting the surgical area. Post-surgery, maintaining a dry environment helps reduce infection and promote proper healing.

Choice D rationale

Though bedrest may be recommended initially, prolonged immobility isn't essential unless specific complications arise. Movement minimizes risks of clot formation and encourages circulation, aiding recovery.
