Question

A nurse is reviewing drugs in a drug reference. The nurse should identify that drugs in the same class share which of the following similarities?

A) They have similar mechanisms of actions.
B) They have the same half-life.
C) They are administered by the same route.
D) They have similar availability.

Answer 1

Drugs in the same class share similar mechanisms of action, route of administration, and availability. For example, drugs in the class of beta-blockers all work by blocking the beta-adrenergic receptors, which leads to a decrease in heart rate and blood pressure.

Step-by-step explanation:

Drugs in the same class share similar mechanisms of action. Mechanism of action refers to how a drug produces its therapeutic effect in the body.

For example, drugs in the class of beta-blockers all work by blocking the beta-adrenergic receptors, which leads to a decrease in heart rate and blood pressure.

Other similarities between drugs in the same class may include the same route of administration, meaning they are taken in the same way (e.g., orally, intravenously), and availability (i.e., how much of the drug is absorbed and available to have its effect).
