Which of the following drugs has a therapeutic effect that prevents thromboembolic event?

Correct Answer: D

Rationale: Clopidogrel is a medication that belongs to the antiplatelet class of drugs. It works by preventing platelets in the blood from sticking together and forming clots, thereby reducing the risk of thromboembolic events, such as heart attacks and strokes. Warfarin (Choice A) is an anticoagulant medication that also helps prevent blood clots, but it works by inhibiting the clotting factors in the blood rather than the platelets. Amlodipine (Choice B) and Nitroglycerine (Choice C) are medications used to treat high blood pressure and angina, respectively, and do not have a direct effect on preventing thromboembolic events.

Correct Answer: C

Rationale: The fundamental action of drugs that can be used as a substitute for what is lacking in the body falls under the category of Replacement. In medical terms, replacement therapy is a type of treatment that involves replacing a hormone or other important substance that is deficient or lacking in the body. For example, individuals with hypothyroidism are often prescribed levothyroxine as a replacement therapy to make up for the thyroid hormone deficiency in their body. Similarly, insulin is used to replace the deficient insulin in individuals with diabetes. Therefore, when drugs are administered to compensate for a deficiency or lack of a specific substance in the body, they are categorized under the fundamental action of Replacement.

Correct Answer: D

Rationale: The clinical features of inflammation are known by the Latin terms "rubor" (redness), "calor" (heat), "tumor" (swelling), and "dolor" (pain). These are classic signs of inflammation that occur in response to tissue injury or infection. "Bacterial invasion" is not a clinical feature, but rather a cause of inflammation. Bacterial invasion can lead to the activation of the inflammatory response, resulting in the characteristic signs of inflammation such as redness, heat, swelling, and pain.

Correct Answer: C

Rationale: The patient is experiencing gastrointestinal upset from taking aspirin. Enteric-coated aspirin would be a suitable alternative in this case because the special coating on the aspirin helps protect the stomach lining and reduces the risk of gastrointestinal irritation. Switching to an enteric-coated aspirin can still provide the antiplatelet benefits needed for secondary prevention of myocardial infarction while minimizing the gastrointestinal side effects. It is important to address the patient's symptoms while ensuring that they continue to receive appropriate treatment for their medical condition.
