A nurse is preparing to administer a medication that acts as an inverse agonist.What does this mean?

The medication increases receptor activity above basal levels

The medication decreases receptor activity below basal levels

The medication has no effect on receptor activity

Inverse agonism does not affect pharmacodynamics

Answer and Explanation

The Correct Answer is B

An inverse agonist is a medication that binds to a specific receptor and decreases its activity below basal levels.Inverse agonists can inhibit constitutive activity of receptors,producing an effect opposite to that of agonists.

a.An inverse agonist decreases,not increases,receptor activity below basal levels.

c.An inverse agonist decreases receptor activity below basal levels,not having no effect on receptor activity.

d.Inverse agonism affects pharmacodynamics by decreasing receptor activity below basal levels.

Correct Answer is A

Explanation

Synergistic effects occur when two drugs produce similar or complementary effects and their combined effect is greater than the sum of their individual effects.When administering two drugs with synergistic effects,the nurse should consider their combined effect and adjust dosing accordingly.

b.Synergistic effects occur when two drugs produce similar or complementary effects and their combined effect is greater than the sum of their individual effects

c.Synergistic effects occur when two drugs produce similar or complementary effects and their combined effect is greater than the sum of their individual effects

d.Synergistic effects affect pharmacodynamics by determining how two drugs interact when given together

A. The medication produces maximal response when bound B. The medication produces minimal response when bound C. The medication produces moderate response when bound D. The intrinsic efficacy does not affect pharmacodynamics

Correct Answer is A

Explanation

Intrinsic efficacy refers to how well a drug activates receptors once bound.A drug with high intrinsic efficacy produces maximal response when bound and can activate receptors fully.

b.A drug with high intrinsic efficacy produces maximal response when bound and can activate receptors fully

c.A drug with high intrinsic efficacy produces maximal response when bound and can activate receptors fully

d.Intrinsic efficacy affects pharmacodynamics by determining how well a drug activates receptors once bound
