Correct Answer: D

Rationale: Clopidogrel is a drug that has a therapeutic effect in preventing thromboembolic events. It is an antiplatelet agent that works by inhibiting platelet aggregation, thus reducing the risk of blood clot formation. Clopidogrel is commonly used in patients at risk for cardiovascular events such as heart attacks and strokes. Warfarin is an anticoagulant medication that also helps prevent blood clots, but it works by a different mechanism than clopidogrel. Amlodipine is a calcium channel blocker used to treat hypertension and angina, while nitroglycerine is a vasodilator used in the treatment of angina.

Correct Answer: A

Rationale: Stevens-Johnson syndrome is a severe and potentially life-threatening adverse reaction associated with the use of Furosemide, a loop diuretic. It is characterized by a severe skin reaction that can cause rashes, blisters, and mucous membrane involvement. Stevens-Johnson syndrome is considered a medical emergency and requires immediate discontinuation of the offending medication. Monitoring and management should be promptly initiated to prevent serious complications. Other side effects of Furosemide include electrolyte imbalances, ototoxicity, and dehydration, but Stevens-Johnson syndrome is a particularly serious adverse reaction that requires immediate attention.

Correct Answer: A

Rationale: A severe adverse effect of iron is the development of iron toxicity, which can lead to symptoms such as seizures. Iron toxicity can occur when there is an excessive accumulation of iron in the body, usually from overdose or prolonged use of iron supplements. Symptoms of iron toxicity can range from mild to severe, with seizures being a serious and potentially life-threatening complication. It is important to seek medical help immediately if symptoms of iron toxicity, including seizures, occur.

Correct Answer: B

Rationale: Ondansetron is a medication commonly used to prevent and treat nausea and vomiting, particularly in patients undergoing chemotherapy or surgery. It belongs to a class of drugs known as antiemetics, which work by blocking serotonin, a neurotransmitter that can trigger nausea and vomiting. By inhibiting the effects of serotonin, ondansetron helps to reduce the incidence and severity of these symptoms, providing a therapeutic effect for individuals experiencing nausea and vomiting.

Correct Answer: D

Rationale: Local anesthetic drugs typically contain an aromatic residue linked to an amine group, giving them a weak base property. They are usually soluble in water when converted into soluble salts, most commonly in the form of hydrochlorides. Additionally, local anesthetics are classified based on their chemical structure, with the key component being an ester or amide linkage. Therefore, choice D, which suggests an acidic group in the structure of a local anesthetic drug, is not accurate.
