Question 1 of 5
Atypical antipsychotic agents (such as clozapine) differ from typical ones:
Correct Answer: D
Rationale: Step 1: Atypical antipsychotic agents like clozapine have reduced risks of extrapyramidal system dysfunction and tardive dyskinesia compared to typical ones. Step 2: Atypical antipsychotics have low affinity for D1 and D2 dopamine receptors. Step 3: Atypical antipsychotics have high affinity for D4 dopamine receptors. Therefore, the correct answer is D because all the statements are true for atypical antipsychotic agents like clozapine. Other choices are incorrect because they do not cover all the key differences between atypical and typical antipsychotic agents.
Question 2 of 5
Anxiolytics are used to treat:
Correct Answer: A
Rationale: Anxiolytics are medications used to treat anxiety disorders, which fall under the category of neurosis. Neurosis is characterized by excessive worry, fear, and distress. Anxiolytics help alleviate symptoms such as restlessness and tension associated with anxiety. Psychosis (choice B) involves loss of touch with reality, narcolepsy (choice C) is a sleep disorder, and bipolar disorders (choice D) involve mood swings between mania and depression. Anxiolytics are not typically indicated for these conditions.
Question 3 of 5
Which of the following agents is related to hallucinogens?
Correct Answer: B
Rationale: The correct answer is B: LSD. Hallucinogens are a class of drugs that alter perception, thoughts, and feelings. LSD, also known as acid, is a well-known hallucinogen that causes visual and auditory hallucinations. Heroin (A) is an opioid, Cocaine (C) is a stimulant, and Opium (D) is an opioid, none of which belong to the hallucinogen category. Therefore, B is the correct answer as it is the only drug related to hallucinogens among the choices provided.
Question 4 of 5
Pick out the bronchodilator drug belonging to sympathomimics:
Correct Answer: B
Rationale: The correct answer is B: Ephedrine. Ephedrine is a sympathomimetic drug that acts by stimulating alpha and beta-adrenergic receptors, leading to bronchodilation. Isoprenaline (A) is a non-selective beta-adrenergic agonist. Atropine (C) is an anticholinergic drug that inhibits parasympathetic activity. Salbutamol (D) is a selective beta2-adrenergic agonist commonly used as a bronchodilator. Therefore, the correct choice for a bronchodilator drug belonging to sympathomimetics is Ephedrine.
Question 5 of 5
Indicate the drug which increases absorption of iron from intestine:
Correct Answer: C
Rationale: The correct answer is C: Ascorbic acid. Ascorbic acid enhances the absorption of non-heme iron by reducing it to a more absorbable form. This helps increase the uptake of iron in the intestine. Cyanocobalamin (A) is Vitamin B12, not involved in iron absorption. Folic acid (B) is essential for DNA synthesis but does not directly affect iron absorption. Erythropoietin (D) is a hormone that stimulates red blood cell production, but it does not impact iron absorption.
