A nurse is preparing to administer haloperidol lactate 7 mg PO to a client who has psychosis.

Available is haloperidol lactate 2 mg/mL oral solution.

How many mL should the nurse plan to administer? (Round to the nearest tenth.

Use a leading zero if it applies.

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.

Choice A rationale:

The client should maintain a normal fluid intake while taking lithium, not limit it to 800 ounces per day.

Choice B rationale:

Lithium can be taken with or without food. This instruction is not necessary.

Choice C rationale:

It can indeed take up to 3 weeks to see the full effects of lithium. This is a correct instruction.

Choice D rationale:

The client should maintain a normal sodium diet while taking lithium, not a low-sodium diet.

So, the correct answer is C, after analyzing all choices.
