Tranquilizers intoxication (5-10 tablets) features include:

Correct Answer: A

Rationale: The correct answer is A because tranquilizers typically produce euphoria, burst of energy, increase in motor activity, and a warm sensation throughout the body. This is due to the sedative effects of tranquilizers, which can initially induce feelings of relaxation and well-being. Choice B is incorrect because visual hallucinations and distorted perception of time and space are more commonly associated with hallucinogens rather than tranquilizers. Choice C is incorrect because physical bliss, body lightness, a wish to fly, and motionlessness are not typical effects of tranquilizer intoxication. Choice D is incorrect because synaesthesia, where senses mix and one sensory experience triggers another, is not a common effect of tranquilizers intoxication. In summary, choice A is the correct answer as it aligns with the typical features of tranquilizers intoxication, while the other choices do not accurately describe the effects of tranquilizers.

Correct Answer: D

Rationale: Step-by-step rationale: 1. Cholosas is a bile stimulant of vegetable origin, containing bile salts. 2. Bile salts in Cholosas promote the production of bile in the liver, aiding in digestion. 3. Oxaphenamide and Papaverine are not bile stimulants. 4. Cholenzyme is an enzyme supplement, not a bile stimulant. In summary, Cholosas is the correct answer as it directly stimulates bile production, while the other choices are not related to bile production.

Correct Answer: D

Rationale: The correct answer is D because glycosides intoxication can lead to a range of cardiac manifestations, including atrioventricular junctional rhythm, second-degree atrioventricular blockade, and ventricular tachycardia. These effects are due to the toxic effects of glycosides on the heart's electrical conduction system. Atrioventricular junctional rhythm occurs when the impulse originates in the atrioventricular node, leading to a slower heart rate. Second-degree atrioventricular blockade involves a delay or interruption in the electrical signals between the atria and ventricles. Ventricular tachycardia is a rapid heart rhythm originating in the ventricles. Therefore, all of the above options are correct manifestations of glycosides intoxication.

Correct Answer: A

Rationale: Rationale: A: Incorrect. Calcium channel blockers do not release nitric oxide. They mainly block calcium entry into cells. B: Correct. L-type calcium channels are the main target of calcium channel blockers. C: Correct. Calcium channel blockers decrease oxygen demand and increase oxygen delivery in angina. D: Correct. Calcium channel blockers reduce calcium entry, leading to relaxation in smooth muscle and decreased contractility in cardiac muscle. Therefore, choice A is incorrect because calcium channel blockers do not release nitric oxide.

Correct Answer: B

Rationale: Step-by-step rationale: 1. Digoxin is a positive inotropic drug of glycoside structure. 2. Digoxin works by inhibiting the sodium-potassium pump, leading to increased intracellular calcium levels, enhancing myocardial contractility. 3. Dopamine is a catecholamine used for its positive inotropic effects but does not have a glycoside structure. 4. Dobutamine is a synthetic catecholamine with positive inotropic effects but lacks a glycoside structure. 5. Adrenaline is a catecholamine with positive inotropic effects, but it is not a glycoside structure. Summary: Digoxin is the correct answer because it has a glycoside structure and exerts positive inotropic effects by increasing intracellular calcium levels. Dopamine, dobutamine, and adrenaline are not glycoside drugs and work through different mechanisms.
