A long-acting drug against both absence and myoclonic seizures is:

Correct Answer: C

Rationale: The correct answer is C: Clonazepam. Clonazepam is a long-acting benzodiazepine that is effectively used to treat both absence and myoclonic seizures due to its ability to enhance the inhibitory neurotransmitter GABA. It has a long half-life, allowing for sustained seizure control. Primidone (A) is mainly used for tonic-clonic seizures, Carbamazepine (B) is more effective for focal seizures, and Phenytoin (D) is typically used for tonic-clonic and focal seizures, but not specifically for absence or myoclonic seizures.

Correct Answer: A

Rationale: The correct answer is A: Inflammation or tissue damage. Non-narcotic analgesics, such as NSAIDs, work by reducing inflammation and inhibiting pain signals. Inflammation and tissue damage often result in pain, making non-narcotic analgesics effective in relieving these types of pain. Trauma, myocardial infarction, and surgery may also cause pain, but non-narcotic analgesics are specifically designed to target inflammation and tissue damage, making them most effective in this context. Therefore, choice A is correct because it aligns with the mechanism of action of non-narcotic analgesics. Choices B, C, and D are incorrect because they do not specifically address the target of action for non-narcotic analgesics.

Correct Answer: D

Rationale: The correct answer is D, Risperidone, because it has high affinity for both D2 and 5-HT2 receptors. Risperidone's strong binding to these receptors contributes to its efficacy in treating psychosis. Droperidol (A) primarily acts on D2 receptors but has limited 5-HT2 affinity. Clozapine (B) has higher affinity for 5-HT2 than D2 receptors. Thiothixene (C) has higher affinity for D2 receptors but relatively lower for 5-HT2 receptors. In summary, Risperidone stands out as it targets both D2 and 5-HT2 receptors, making it a suitable choice for treating psychosis.

Correct Answer: D

Rationale: Step 1: Adaptogens are known for increasing resistance to stress and promoting adaptation to various stressors. Step 2: The correct answer, D, aligns with the primary function of adaptogens. Step 3: Option A pertains more to performance enhancement and recovery, not specifically stress resilience. Step 4: Option B focuses on physiological responses, not stress adaptation. Step 5: Option C addresses fatigue relief but does not emphasize stress resistance like adaptogens.

Correct Answer: D

Rationale: The correct answer is D because all the listed drugs can be used as antianxiety agents. Beta-blocking drugs, like propranolol, help with physical symptoms of anxiety. Clonidine, a partial agonist of alpha2 receptors, can also reduce anxiety symptoms. Tricyclic antidepressants, such as imipramine, are sometimes used off-label for anxiety disorders. Therefore, all of the above options are valid choices for antianxiety treatment. The other choices are incorrect because each of them individually may not cover the broad spectrum of antianxiety effects provided by the combination of the drugs listed in option D.
