What is the category class of Valproate?

Correct Answer: C

Rationale: Valproate belongs to the category class of anticonvulsants, which means it is primarily used to treat seizures and epilepsy. Additionally, valproate also has properties that make it effective in the treatment of vascular headaches, such as migraines. It is not an anticoagulant, antianxiety medication like benzodiazepines, or a mood stabilizer.

Correct Answer: A

Rationale: Montelukast is primarily used for the prevention and treatment of asthma. It is a leukotriene receptor antagonist that works by blocking leukotrienes, substances in the body that cause symptoms of asthma and allergic rhinitis. By blocking leukotrienes, Montelukast helps to reduce inflammation in the airways, decrease bronchoconstriction, and ultimately improve asthma symptoms and prevent asthma attacks. It is not used for lowering pain levels, treating depression, or improving wakefulness in patients.

Correct Answer: B

Rationale: Sedatives and hypnotics are drugs that act as depressants on the central nervous system. They slow down brain activity, leading to relaxation, drowsiness, and in higher doses, inducing sleep. These drugs are commonly used to reduce anxiety, promote sleep, or induce anesthesia. Therefore, the correct classification for sedatives and hypnotics is as depressants.

Correct Answer: D

Rationale: Bradykinin is not an eicosanoid. Eicosanoids are signaling molecules derived from arachidonic acid or other polyunsaturated fatty acids, including prostaglandins, prostacyclins, thromboxanes, and leukotrienes. Bradykinin, on the other hand, is a peptide that functions as a mediator of inflammation and pain by promoting vasodilation and increasing vascular permeability.

Correct Answer: D

Rationale: Low-molecular-weight heparin is commonly administered to postoperative patients to help prevent thrombus formation caused by slow venous blood flow. This medication works by inhibiting the formation of blood clots. It is considered safer and more effective than unfractionated heparin in preventing venous thromboembolism in surgical patients. Aspirin and clopidogrel are antiplatelet medications that are more commonly used for preventing arterial thrombosis rather than venous thrombosis. Alteplase is a thrombolytic medication used to dissolve existing blood clots, rather than prevent their formation.
