Correct Answer: B

Rationale: Protamine is the antidote for Heparin. Heparin is an anticoagulant medication that works by increasing the activity of antithrombin III, leading to the inhibition of clotting factors. In cases of excessive bleeding or overdose with Heparin, protamine can be administered to neutralize its anticoagulant effects. Protamine works by binding to heparin to form a stable complex, thereby reversing the anticoagulant activity of Heparin. It is important for healthcare providers to be familiar with the antidotes for various medications to manage potential complications effectively.

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: B

Rationale: St. John's Wort is known to interact with phenytoin, a drug commonly used to treat seizures. St. John's Wort can decrease the effectiveness of phenytoin by increasing its metabolism in the liver. This interaction can lead to lower levels of phenytoin in the bloodstream, potentially reducing its therapeutic effects and increasing the risk of seizure recurrence. It is important for individuals taking phenytoin to avoid using St. John's Wort to prevent this drug interaction.

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.
