A patient is prescribed 800 mg of quetiapine per day, divided into two doses. If quetiapine is available in 200 mg tablets, how many tablets should be given per dose?
2 tablets.
4 tablets.
5 tablets.
3 tablets.
The Correct Answer is A
Choice A reason: The total daily dose of quetiapine is 800 mg, divided into two doses, meaning each dose is 400 mg (800 mg ÷ 2). With 200 mg tablets, each dose requires 400 mg ÷ 200 mg = 2 tablets. This is the correct calculation for the number of tablets per dose.
Choice B reason: Four tablets per dose would result in 800 mg per dose (4 × 200 mg), totaling 1600 mg daily, which doubles the prescribed daily dose of 800 mg. This is incorrect and could lead to an overdose.
Choice C reason: Five tablets per dose would result in 1000 mg per dose (5 × 200 mg), totaling 2000 mg daily, far exceeding the prescribed 800 mg daily dose. This is incorrect and unsafe.
Choice D reason: Three tablets per dose would result in 600 mg per dose (3 × 200 mg), totaling 1200 mg daily, which exceeds the prescribed 800 mg daily dose. This is incorrect and not aligned with the prescription.

Correct Answer is D
Explanation
Choice A reason: Ignoring pain temporarily is an example of suppression, which is considered an adaptive coping strategy.
Choice B reason: Slamming a drawer represents displacement of frustration, which, while immature, can still be considered a common short-term coping outlet.
Choice C reason: Buying a gift after flirting is an example of undoing, which attempts to counteract negative feelings, and can sometimes be adaptive.
Choice D reason: Forgetting to schedule important appointments due to fear is repression/avoidance, which prevents the person from addressing health needs and is maladaptive.
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.
