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: Mysophobia is the fear of germs or contamination, which does not match the client’s fear of leaving home.
Choice B reason: Xenophobia is an intense dislike or fear of strangers or foreigners, unrelated to avoiding outdoor spaces.
Choice C reason: Acrophobia is the fear of heights, not the fear of leaving one’s home.
Choice D reason: Agoraphobia involves anxiety about being in places where escape might be difficult, often resulting in refusal to leave the home without assistance, which fits this scenario.
Correct Answer is B
Explanation
Choice A reason:Alcohol tolerance is not a medical emergency and is not caused by withdrawal. It refers to needing more alcohol to achieve the same effect, making this statement incorrect.
Choice B reason:Alcohol tolerance involves a decreased physical response to the same amount of alcohol over time, requiring higher doses for the same effect. This statement accurately reflects understanding of tolerance.
Choice C reason:Alcohol tolerance does not produce physical changes when alcohol is not consumed. It describes the body’s reduced response to alcohol, not withdrawal symptoms or other changes.
Choice D reason:Alcohol tolerance does not directly increase the effects of opiates. While cross-tolerance can occur, this statement inaccurately suggests a direct causal relationship, making it incorrect.
