Answer:
"heart attacks are most often caused by a sudden drop in blood pressure."
The statement which is true of heart attacks is heart attacks are most often caused by a sudden drop in blood pressure. Thus, option B is correct.
In which case aspirin is administered?Aspirin is administered in patients who produce blood hypercoagulation, that is why it is prescribed in order to antiaggregate platelets or platelet thrombi, this is how the platelets do not add or encompass each other and do not generate obstructions in the blood vessels to trigger an acute myocardial infarction or cerebrovascular accident.
Aspirin is an anticoagulant that is made up of N acetylsalicylic acid, that is, by an acid that inhibits the union of platelets with each other, that is why these in systemic situations where there is a tendency to hypercoagulation of the blood is a benefit for the patient .
When these arteries are blocked by a platelet engulfment, the irrigation does not oxygenate the tissue and it suffers a transient hypoxia or anoxia that leads to partial necrosis and even in some cases of more serious situation it could be total where the person loses his life.
Therefore, The statement which is true of heart attacks is heart attacks are most often caused by a sudden drop in blood pressure. Thus, option B is correct.

Here the correct answer is, "I call 911 immediately, and if I can get him to a hospital faster than responders, I do so." That is in Option C, as based on the symptoms described, it is likely that Claus is having a stroke.
What is a stroke?A stroke occurs when there is a disruption of blood flow to the brain, either due to a blocked blood vessel (ischemic stroke) or a ruptured blood vessel (hemorrhagic stroke). In either case, the brain cells begin to die within minutes due to the lack of oxygen and nutrients. Therefore, prompt medical attention is crucial to minimize the damage and prevent long-term disability. The symptoms of a stroke can vary depending on the location and severity of the damage to the brain. Some of the most common signs of a stroke include weakness or numbness on one side of the body, facial drooping, slurred speech, confusion, and difficulty with coordination or balance.
Hence, the correct answer is, "I call 911 immediately, and if I can get him to a hospital faster than responders, I do so." That is in Option C.
