Correct Answer is A

Explanation

Choice A rationale

Aspirin is an antipyretic and analgesic, effective in reducing fever and relieving mild to moderate pain by inhibiting cyclooxygenase enzymes.

Choice B rationale

Aspirin is not used to lower blood pressure; antihypertensive drugs are prescribed for that purpose.

Choice C rationale

Aspirin does not treat bacterial infections; antibiotics are used to eliminate bacterial pathogens.

Choice D rationale

Aspirin does not cure viral infections; antiviral medications are required to treat such conditions. .

A. Medication routes that are affected by the first-pass effect include intravenous, intramuscular, and intradermal. B. Enteric-coated tablets and capsules are affected by the first-pass effect except a pharmacologic effect. C. The first-pass effect is when the liver activates all medications on their first pass through the liver. D. Enteral medications may need a higher dose due to the first-pass effect.

Correct Answer is D

Explanation

Choice A rationale

Intravenous, intramuscular, and intradermal routes bypass the first-pass effect as they do not pass through the liver first.

Choice B rationale

Enteric-coated tablets and capsules are designed to bypass the stomach and dissolve in the intestines, reducing the first-pass effect.

Choice C rationale

The first-pass effect involves the liver metabolizing and inactivating a portion of the medication on its first pass through the liver.

Choice D rationale

Enteral medications, which pass through the digestive system, may require higher doses due to the first-pass effect where the liver metabolizes the medication before it reaches systemic circulation. .
