Following are examples of generalized seizures, except

Correct Answer: C

Rationale: Simple partial seizures are focal seizures and not generalized seizures making them an exception.

Correct Answer: C

Rationale: Antipsychotics (e.g., haloperidol) block central D2 (choice A) and 5-HT2 receptors (choice B) for efficacy, and muscarinic receptors (choice D) peripherally, causing side effects. Peripheral H2 receptors (choice C), involved in gastric acid secretion, aren't significantly affected; H1 antagonism occurs instead. This exception clarifies antipsychotic receptor profiles.

Correct Answer: A

Rationale: The correct answer is A because alcohol can enhance the side effects of anticholinergic therapy, such as dizziness and drowsiness. Alcohol can also worsen symptoms of Parkinson's disease. Choices B and C are incorrect because there is no direct interaction between cigarettes, caffeine, and anticholinergic therapy. Choice D is incorrect because while it may help relieve dry mouth, it is not specifically related to the use of anticholinergic therapy for Parkinson's disease.

Correct Answer: A

Rationale: The MAC (minimum alveolar concentration) of an inhalational anesthetic is defined as the alveolar concentration at which 50% of patients do not move in response to a surgical stimulus. It is related to the blood/gas partition coefficient of the anesthetic, which determines the rate at which the anesthetic enters and leaves the bloodstream, influencing its potency.

Correct Answer: C

Rationale: NMDA receptors are crucial for synaptic plasticity and long-term potentiation.
