What does the onset of action describe?
How long the drug stays in the system
How quickly the drug is excreted
How quickly the drug takes effect
How the drug binds to proteins
The duration of action of a drug refers to:
How long the drug stays on the shelf
How long it takes to metabolize the drug
How long the drug has a therapeutic effect
How long it takes for the drug to reach the liver
The purpose of a maintenance dose is to:
Increase the onset of action
Achieve a peak drug concentration
Maintain a desired drug level in the blood
Reduce the risk of side effects
A loading dose is used to:
Decrease metabolism of a drug
Quickly achieve therapeutic levels
Slow the drug's excretion
Increase enzyme activity
Peak level refers to:
The lowest concentration of drug in the blood
The first dose given
The highest concentration of drug in the blood
The time when the drug is first absorbed
Trough level is defined as:
The amount of drug needed for a loading dose
The lowest concentration of drug in the blood
The amount of drug excreted
The most common dose used
What is steady state?
When drug absorption stops
When metabolism exceeds excretion
When drug intake equals drug elimination
When side effects are reduced
Which of the following affects drug absorption?
Route of administration
Patient's age
Metabolic rate
All of the above
The blood-brain barrier primarily:
Increases drug absorption
Prevents drugs from being excreted
Limits drug entry into the brain
Speeds up metabolism
The first-pass effect refers to drug metabolism that occurs in the:
Kidneys
Brain
Liver
Lungs
Drugs bound to proteins in the blood are:
More easily excreted
Biologically inactive
More potent
Absorbed faster
The term 'free drug' refers to:
Drugs in the liver
Drugs bound to proteins
Unbound drugs available for action
Excreted drugs
Half-life (T2) describes:
The time it takes for half of the drug to be excreted
The time it takes for half of the drug's concentration to decrease
The time between doses
The duration of action
Absorption is the movement of a drug from the site of administration to
The lower extremities
The spinal cord
The brain
The bloodstream
Acetaminophen + alcohol increases risk for
Diabetes
Liver damage
Fatigue
Memory loss
Warfarin + decreased intake of vitamin K increases risk of
Bloating
Nausea
Clotting
Fatigue
Aspirin + warfarin can lead to
Hemorrhage
Dizziness
Cyanosis
Water-soluble drugs cannot
Be taken with food
Be crushed, scored, or opened
Digest properly
Cross the blood-brain barrier
Lipid-soluble drugs can
Be hid in a patient’s food
Cross the blood-brain barrier
Be a choking hazard
Replace a water-soluble drug
