Which of the following antipsychotic drugs is typical?

Correct Answer: C

Rationale: The correct answer is C: Haloperidol. Haloperidol is considered a typical antipsychotic drug due to its high affinity for dopamine D2 receptors and its strong dopamine-blocking effects. Typical antipsychotics primarily target dopamine receptors, leading to the alleviation of positive symptoms of psychosis. Clozapine (A), Quetiapine (B), and Olanzapine (D) are atypical antipsychotics, as they target multiple neurotransmitter systems, including serotonin and dopamine. They are preferred for their reduced risk of extrapyramidal side effects compared to typical antipsychotics.

Correct Answer: B

Rationale: The correct answer is B: Piracetam. Piracetam is a CNS stimulant known for improving cognitive function and memory, making it beneficial in pediatric medicine for enhancing learning abilities and school performance. It does not have the same potential for abuse or addiction as amphetamines (choice D). Meridil (choice A) and Bemegride (choice C) are not commonly used CNS stimulants in pediatric medicine and do not have the same cognitive-enhancing effects as Piracetam.

Correct Answer: C

Rationale: The correct answer is C because psychosis with visual and auditory hallucinations is not a common characteristic of cocaine abstinent syndrome. A: Feeling of depression, irritability, confusion, insomnia in the initial days is common due to withdrawal symptoms. B: Depression, apathy, excessive appetite, and the wish to sleep in the subsequent days are typical withdrawal symptoms. D: A new attack of depression, anxiety, irritability, dullness, and intense thirst for cocaine after initial improvement is consistent with the stages of cocaine abstinent syndrome.

Correct Answer: B

Rationale: The correct answer is B: Tachycardia. Non-selective beta2-adrenomimics stimulate both beta1 and beta2 adrenergic receptors, leading to increased heart rate (tachycardia) due to beta1 receptor activation. A: Depression of the breathing centre is not a side effect of non-selective beta2-adrenomimics. C: Peripheral vasoconstriction is more commonly associated with alpha-adrenergic agonists, not beta2-adrenomimics. D: Dry mouth is not a common side effect of beta-adrenergic stimulation.

Correct Answer: B

Rationale: The correct answer is B: Folic acid. Folic acid is not a drug used for iron deficiency anemia; it is a B-vitamin essential for normal cellular function but not directly related to iron supplementation. Ferrous sulfate, ferrous gluconate, and ferrous fumarate are all iron salts commonly used to treat iron deficiency anemia by replenishing the body's iron stores. Folic acid, on the other hand, is primarily used to prevent neural tube defects in pregnancy and to treat certain types of anemia not related to iron deficiency.
