A nurse is preparing to administer valproic acid 500 mg PO. Available is valproic acid oral solution 250 mg/5 mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number.)
Answer and Explanation

The Correct Answer is ["10"]

Step 1: Determine the Medication Concentration

  • The total amount of medication in the solution is 250 mg.
  • The total volume of the solution is 5 mL.
  • To find the concentration per mL:
    250 mg ÷ 5 mL = 50 mg/mL

Step 2: Determine the Required Volume

  • The prescribed dose is 500 mg.
  • To find the volume needed:
    500 mg ÷ 50 mg/mL = 10 mL

Thus, the nurse should administer 10 mL of the solution to deliver the required 500 mg dose.

Correct Answer is B

Explanation

Choice A rationale:

Pseudoparkinsonism mimics the symptoms of Parkinson’s disease but is not typically characterized by choreiform movements, lip smacking, and spastic facial distortions.

Choice B rationale:

Tardive dyskinesia, a potential side effect of long-term use of chlorpromazine, is characterized by involuntary movements such as lip smacking and facial distortions.

Choice C rationale:

Akathisia is characterized by a sense of restlessness and a compulsion to move, not typically by the symptoms described.

Choice D rationale:

Dystonia involves involuntary muscle contractions and distortions but not typically the specific symptoms described.

So, the correct answer is B.

Correct Answer is D

Explanation

Choice A rationale:

Treating nasal rhinitis with an over-the-counter antihistamine is not directly related to neostigmine use or myasthenia gravis.

Choice B rationale:

If a medication dose is missed, wait until the next scheduled dose to take the medication is not the best advice. Neostigmine should be taken at regular intervals for maximum effectiveness.

Choice C rationale:

Expecting diaphoresis as a side effect of the neostigmine is not accurate. Diaphoresis is not a common side effect of neostigmine.

Choice D rationale:

Taking the medication 45 minutes before eating is correct. This timing helps maximize the medication’s effectiveness during meals, when muscle strength for swallowing is crucial.

So, the correct answer is,

D.
