A

1) Chemical changes in the body by which energy is provided. 2) breakdown of a drug to an inactive form.

41
Q

Mechanism of Action

A

The way that a drug modifies the target tissue. The mechanism can be through receptors, enzymes, or nonselective interactions.

42
Q

Nursing Implications

A

.

43
Q

Onset of Action

A

The time required for a drug to elicit a therapeutic response after dosing.

44
Q

A

The commitment and approach used to continuously improve every process in every part of an organization, with the intent of meeting and exceeding customer expectations and outcomes.

45
Q

Peak

A

The maximum concentration of a drug in the body after administration, usually measured in a blood sample for therapeutic drug monitoring.

46
Q

Peak of Action

A

The time in which the effect of a drug is at optimal strength.
