Medication Flashcards
Pharmacodynamics
is the study of how a drug works, its relationship to
drug concentrations, and how the body responds.
Peak plasma level
is when a drug is at its highest concentration, not
necessarily at its most therapeutic level.
Trough serum levels
are the lowest level of concentration of a medication that correlates to the rate of elimination
Stevens-Johnson Syndrome
that develops 1-14 days following drug administration. SJS is manifested by respiratory
distress, fever, chills, a diffuse fine rash, and then blisters
Pharmacokinetics
is the study of the absorption, metabolism,
distribution, and excretion of drugs in the human body.
Metabolism or biotransformation
is the process of converting a medication to a form that is easily
excreted from the body.
Prodrugs
are inactive chemicals that are transformed through metabolism to become active before they have therapeutic effect
teratogenic meds
known to cause fetal defects
High-alert medications
insulin, opiates, narcotics, intravenous heparin, and injectable potassium chloride are high-alert medications.
Time-critical medications
are those that when administered either 30 minutes before or after the scheduled administration time can cause harm to client or substandard
pharmacological effect.
Non-time critical medications
are defined as medications that can be administered between one and two hours early or late
without causing harm or substandard pharmacological effects to the client
