Pharmacology /Nursing Nursing Care Pharmacokinetics Flashcards
nursing care that encompasses pharmacologic principles, specifically pharmacokinetics as related to the nursing process (27 cards)
What is pharmacokinetics?
Pharmacokinetics is the study of how drugs move through the body, including absorption, distribution, metabolism, and excretion.
What are the four main processes involved in pharmacokinetics?
Absorption, distribution, metabolism, and excretion.
True or False: Pharmacokinetics only concerns the absorption of drugs.
False
Fill in the blank: The process by which a drug enters the bloodstream is called __________.
absorption
What does the term ‘bioavailability’ refer to?
The proportion of a drug that enters the circulation when introduced into the body and is available for action.
True or False: Factors such as age, weight, and health status can affect pharmacokinetics.
True
What is the primary organ responsible for drug metabolism?
The liver.
Multiple Choice: Which of the following factors can influence drug absorption? a) pH of the stomach, b) blood flow to the area, c) drug formulation, d) all of the above.
d) all of the above.
What is the significance of half-life in pharmacokinetics?
Half-life is the time it takes for the concentration of a drug in the bloodstream to reduce by half, influencing dosing schedules.
Fill in the blank: The process of distributing the drug throughout the body is known as __________.
distribution
True or False: Renal function has no effect on drug excretion.
False
What role do nurses play in pharmacokinetics?
Nurses assess patient factors that influence pharmacokinetics and adjust medication administration accordingly.
Multiple Choice: Which of the following is NOT a route of drug administration? a) Oral, b) Intravenous, c) Subcutaneous, d) Synchronous.
d) Synchronous.
What is the term for the conversion of a drug into a form that can be easily eliminated from the body?
Metabolism.
True or False: Drugs can only be excreted through urine.
False
What is the primary purpose of understanding pharmacokinetics in nursing?
To ensure safe and effective medication administration based on individual patient needs.
Fill in the blank: The __________ is the time it takes for the drug to begin to have an effect.
onset
What is an example of a factor that can affect drug distribution?
Body fat percentage.
Multiple Choice: Which of the following can alter drug metabolism? a) Genetics, b) Drug interactions, c) Liver disease, d) All of the above.
d) All of the above.
True or False: Pharmacokinetic studies are unnecessary for all medications.
False
What is the effect of protein binding on drug distribution?
Drugs that are highly protein-bound may have a lower free concentration in the bloodstream, affecting their efficacy.
Fill in the blank: The __________ phase of pharmacokinetics involves the elimination of the drug from the body.
excretion
What is a common method of drug excretion?
Urination.
Multiple Choice: Which of the following is a key consideration for elderly patients in pharmacokinetics? a) Decreased liver function, b) Increased metabolism, c) Higher blood volume, d) None of the above.
a) Decreased liver function.
