Cardiovascular Treatment Drugs Questions
Question 1 of 5
In contrast to morphine ,methadone:
Correct Answer: D
Rationale: Step-by-step rationale: 1. Methadone causes tolerance and physical dependence more slowly than morphine due to its longer half-life. 2. Methadone is more effective orally as it has high bioavailability compared to morphine. 3. Withdrawal from methadone is less severe but more prolonged, making it easier to taper off. 4. Therefore, all the statements are true, making option D the correct answer. Summary: A. Incorrect - Methadone causes tolerance and physical dependence more slowly than morphine. B. Incorrect - Methadone is more effective orally compared to morphine. C. Incorrect - Withdrawal from methadone is less severe but more prolonged.
Question 2 of 5
Tricyclic antidepressants are:
Correct Answer: D
Rationale: Tricyclic antidepressants inhibit the reuptake of both norepinephrine and serotonin in the brain, making them mixed norepinephrine and serotonin reuptake inhibitors. This mechanism contributes to their antidepressant effects. Options A and C are incorrect as tricyclic antidepressants are not highly selective for either serotonin or norepinephrine reuptake. Option B is incorrect as tricyclic antidepressants are not monoamine oxidase inhibitors. Thus, the correct answer is D due to the dual mechanism of action of tricyclic antidepressants on norepinephrine and serotonin reuptake.
Question 3 of 5
Indicate the CNS stimulant which is used in pediatric medicine as it improves the communication with the child increases the ability to study and communication with peers improves school-performance?
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.
Question 4 of 5
Characteristics of cocaine abstinent syndrome include all of the following phases EXCEPT:
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.
Question 5 of 5
Select the side-effect characteristic for non-selective beta2-adrenomimics:
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.
