Question 1 of 5
Most of non-narcotic analgetics have:
Correct Answer: D
Rationale: The correct answer is D: All of the above. Non-narcotic analgesics, such as NSAIDs and acetaminophen, have multiple effects including anti-inflammatory (A), analgesic (B), and antipyretic (C) effects. Anti-inflammatory effect helps reduce inflammation, analgesic effect helps relieve pain, and antipyretic effect helps reduce fever. Therefore, the correct answer is D as non-narcotic analgesics exhibit all these effects. Choices A, B, and C are incorrect because non-narcotic analgesics do not have just one of these effects but rather a combination of all three.
Question 2 of 5
Which of the following CNS psychostimulants is a sydnonymine derivative?
Correct Answer: B
Rationale: The correct answer is B: Sydnocarb. Sydnocarb is a CNS psychostimulant that is a sydnonymine derivative. This is because the chemical structure of Sydnocarb contains the sydnone imine group, which is characteristic of sydnonimine derivatives. A: Caffeine is not a sydnonimine derivative, as it does not contain the sydnone imine group. C: Meridil (methylphenidate hydrochloride) is not a sydnonimine derivative, as it does not contain the sydnone imine group. D: Amphetamine is not a sydnonimine derivative, as it does not contain the sydnone imine group.
Question 3 of 5
Psychologic dependence is:
Correct Answer: D
Rationale: Step 1: Psychologic dependence can involve decreased responsiveness (tolerance) to a drug due to repeated exposure. Step 2: It can also manifest as drug-specific withdrawal symptoms upon sudden discontinuation. Step 3: Additionally, psychologic dependence includes compulsive drug-seeking behavior. Step 4: Therefore, the correct answer is D, as it encompasses all these aspects of psychologic dependence. Summary: A is incorrect as it only covers tolerance, B is incorrect as it focuses solely on withdrawal symptoms, and C is incorrect as it mentions only compulsive drug-seeking behavior. The correct answer, D, includes all these components, making it the most comprehensive choice.
Question 4 of 5
Indicate the intravenous anesthetic,which is an ultra-short-acting barbiturate:
Correct Answer: B
Rationale: Step-by-step rationale for choice B: Thiopental: 1. Thiopental is an ultra-short-acting barbiturate commonly used as an intravenous anesthetic. 2. It has a rapid onset of action and short duration of effect, making it ideal for induction of anesthesia. 3. Its pharmacokinetics allow for quick recovery and minimal residual effects. 4. Fentanyl (choice A) is a synthetic opioid, Midazolam (choice C) is a benzodiazepine, and Ketamine (choice D) is a dissociative anesthetic, not barbiturate.
Question 5 of 5
Select an anorexigenic agent affecting serotoninergic system:
Correct Answer: A
Rationale: The correct answer is A: Fenfluramine. Fenfluramine is an anorexigenic agent that affects the serotoninergic system by increasing serotonin levels, leading to appetite suppression. It works by inhibiting the reuptake of serotonin, thereby increasing its availability in the brain. This mechanism helps in reducing food intake and promoting weight loss. Other choices - B: Fepranone, C: Desopimone, and D: Masindole - do not directly affect the serotoninergic system and are not known for their anorexigenic effects. Fepranone is a beta-adrenergic agonist, Desopimone is a dopamine reuptake inhibitor, and Masindole is a monoamine oxidase inhibitor. These mechanisms are not primarily associated with appetite suppression or weight loss.
