Final answer:
c. 160-325 mg. The recommended oral dose of ASA for a patient with suspected acute coronary syndrome (ACS) is 160-325 mg. This dosage helps in preventing the progression of a heart attack due to its antiplatelet effects. Lower or higher doses have different uses and are not typically recommended for immediate ACS management.
Step-by-step explanation:
The recommended oral dose of acetylsalicylic acid (ASA) for a patient with suspected acute coronary syndrome (ACS) is c. 160-325 mg. This dose has been shown to provide the best balance between efficacy and safety. It's important to administer ASA as soon as ACS is suspected because of its antiplatelet effects, which can help to prevent the progression of a heart attack. Dosages of 81 mg are typically used for long-term prevention of cardiovascular events in certain patients, whereas doses of 325-650 mg could be used for pain relief in different conditions. The 40 mg dose is not commonly used in the context of ACS management.
