A nurse is preparing to administer an antipsychotic medication to a patient diagnosed with schizophrenia. The prescribed dose is 10 mg, and the medication is available in 5 mg tablets. How many tablets should the nurse administer?
0 tablet
3 tablets
0.5 tablet
2 tablets
The Correct Answer is D
Choice A reason: Zero tablets would result in the patient not receiving the required medication.
Choice B reason: Three tablets equal 15 mg, which is above the prescribed dose and could cause adverse effects.
Choice C reason: Half a tablet equals 2.5 mg, which is insufficient to meet the 10 mg prescribed dose.
Choice D reason: Two tablets equal the prescribed 10 mg, which is correct.

Correct Answer is C
Explanation
Choice A reason:Clozapine is an antipsychotic used primarily for schizophrenia, not for preventing seizures. While it may lower the seizure threshold as a side effect, it is not prescribed for seizure control, making this statement incorrect.
Choice B reason:Clozapine is typically administered orally, not by intramuscular injection every 2 weeks. Long-acting injectable antipsychotics exist, but clozapine is not one of them, so this statement does not reflect correct understanding.
Choice C reason:Clozapine can cause orthostatic hypotension, leading to dizziness or fainting upon standing. Rising slowly from a lying position helps prevent this, indicating the client understands an important precaution for safe use of the medication.
Choice D reason:Ringing in the ears (tinnitus) is not a common side effect of clozapine. More common side effects include sedation, weight gain, and agranulocytosis, so this statement does not show correct understanding.
Correct Answer is B
Explanation
Choice A reason: Risperidone more commonly causes orthostatic hypotension rather than hypertension, so this is misleading information.
Choice B reason: Constipation is a frequent adverse effect due to anticholinergic action. Increasing fluid and fiber is an appropriate teaching strategy to manage this side effect.
Choice C reason: Weekly blood tests are not required for risperidone; such monitoring is typically associated with clozapine due to the risk of agranulocytosis.
Choice D reason: Risperidone is more likely to cause weight gain and metabolic syndrome, not weight loss, making this response inaccurate.
