Fluoxetine has fewer adverse effects because of:

Correct Answer: C

Rationale: Rationale: Choice C is correct because fluoxetine has minimal binding to cholinergic, histaminic, and alpha-adrenergic receptors, reducing the likelihood of adverse effects compared to drugs that bind strongly to these receptors. Choices A and B are incorrect because fluoxetine specifically inhibits serotonin reuptake, not norepinephrine, and it does not deplete neurotransmitter stores. Choice D is incorrect because not all the statements in A and B are true for fluoxetine.

Correct Answer: D

Rationale: The correct answer is D, "All of the above." LSD produces mood swings due to its impact on serotonin levels. It impairs memory, thinking, and judgment by affecting the brain's cognitive functions. LSD also causes perceptual distortions by altering sensory perceptions. Therefore, all choices A, B, and C are correct effects of LSD.

Correct Answer: A

Rationale: The correct answer is A because theophyllines are bronchodilators that help relax the muscles in the airways, making it easier to breathe. By preventing airway constriction, theophyllines can indeed help prevent night asthmatic attacks. Choice B is incorrect because the statement is true. Choice C is incorrect because not all options are correct - only option A is. Choice D is incorrect because the statement is true.

Correct Answer: B

Rationale: The correct answer is B: Fercoven because it is not a common drug used for oral administration. Ferrous sulfate, ferrous lactate, and ferrous fumarate are commonly used oral iron supplements for treating iron deficiency anemia. Fercoven is not a known drug for oral administration in the context of iron supplementation. Therefore, it is the outlier among the choices provided.

Correct Answer: C

Rationale: The correct answer is C. Type III phosphodiesterase inhibitors increase cAMP levels in cardiac myocytes, leading to positive inotropic and vasodilatory effects, reducing afterload. They are associated with the risk of cardiac arrhythmias due to their effects on cardiac contractility. However, they do not show significant cross-tolerance with beta-receptor agonists, as they act via a different mechanism. Therefore, choice C is incorrect.
