Tick mixed (opioid/non-opioid) agent:

Correct Answer: B

Rationale: The correct answer is B: Tramadol. Tramadol is a mixed (opioid/non-opioid) agent as it acts on opioid receptors and inhibits the reuptake of serotonin and norepinephrine. This dual mechanism provides both opioid and non-opioid effects. Paracetamol (A) is a non-opioid analgesic, sodium valproate (C) is an anticonvulsant, and butorphanol (D) is a mixed opioid agonist-antagonist but not typically used as a tick mixed agent.

Correct Answer: D

Rationale: The correct answer is D. Camphor is not a respiratory or cardiac analeptic. Cordiamine, Bemegride, and Caffeine are all known to have stimulant effects on the respiratory and cardiac systems. Cordiamine and Bemegride specifically act as central nervous system stimulants, while Caffeine is a known respiratory and cardiac stimulant. Camphor, on the other hand, is commonly used in topical products for its cooling and soothing effects and does not have any direct stimulant effects on the respiratory or cardiac systems. Therefore, D is the correct answer as it does not belong to the category of respiratory and cardiac analeptics.

Correct Answer: C

Rationale: Rationale: Diazepam belongs to strong euphorizing agents due to its ability to produce feelings of euphoria and relaxation. It is a benzodiazepine with potent anxiolytic and sedative properties. Mebicarum (A) is an anxiolytic, not a strong euphorizer. Buspirone (B) is an anxiolytic without strong euphorizing effects. Chlordiazepoxide (D) is also a benzodiazepine but is not known for strong euphorizing properties.

Correct Answer: B

Rationale: The correct answer is B: Derivatives of Ipecacuanha and Thermopsis. These substances stimulate the reflex mechanism of coughing, leading to increased mucus clearance from the airways. Mucolytics like Ambroxol (choice D) thin out mucus, while sodium benzoate (choice A) is a preservative and trypsin (choice C) is an enzyme and not an expectorant. Therefore, B is correct as it directly promotes the cough reflex for mucus expulsion.

Correct Answer: B

Rationale: The correct answer is B: Cholenszyme. Cholenszyme is a digestive enzyme supplement and does not stimulate bile production or secretion. Chenodiol is a bile acid that promotes bile flow. Oxaphenamide is a choleretic agent that increases bile secretion. Cholosas contains bile salts and helps stimulate bile production. Therefore, Cholenszyme is the only option that does not directly stimulate bile production or secretion.
