A nurse is preparing to administer risperidone 5 mg PO.

Available is risperidone 2 mg tablets. How many tablets should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale:

Blistering around the insertion site is not a common sign of phlebitis. It could indicate a more severe complication like extravasation or infiltration.

Choice B rationale:

Streak formation along the vein is a classic sign of phlebitis. It indicates inflammation and possible infection.

Choice C rationale:

Erythema at the insertion site is another common sign of phlebitis. It indicates inflammation.

Choice D rationale:

Warmth at the insertion site is also a common sign of phlebitis. It is caused by increased blood flow to the area due to inflammation. So, the correct answers are B, C, and D.

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.
