A nurse is preparing to administer lorazepam 2 mg PO. Available is lorazepam 1 mg tablets.

How many tablets should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

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.

Choice A rationale:

Baclofen is a muscle relaxant and antispastic agent. It can cause drowsiness and affect the ability to drive or operate machinery. Therefore, it’s advisable to avoid driving until the medication’s effects are evident.

Choice B rationale:

Headache is not a reason to stop taking baclofen. If a headache occurs, the client should consult with their healthcare provider for appropriate management.

Choice C rationale:

Diarrhea is not a common adverse effect of baclofen. More common side effects include drowsiness, dizziness, weakness, and fatigue.

Choice D rationale:

Baclofen can be taken with or without food. Taking it on an empty stomach is not necessary and may increase the risk of stomach upset.

So, the correct answer is A.
