Study Notes
Bioavailability of Medications
- Bioequivalent drugs have the same bioavailability when absorbed into the circulation.
- A drug's steady state is reached when elimination equals absorption.
- Synergistic drugs have a combined effect greater than the sum of their individual effects.
- A prodrug is inactive until converted to an active metabolite within the body.
Intravenous Medications
- Intravenous (IV) medications bypass the first-pass effect, resulting in faster absorption.
- IV medications do not influence the frequency of adverse effects or allergic reactions.
Parenteral Drug Administration
- Parenteral drugs bypass the first-pass effect.
- Reduced bloodflow to the stomach can affect absorption of parenteral drugs.
- Increased peristaltic activity speeds up gastric emptying.
Pharmacokinetics in the Elderly
- Microsomal enzyme levels decrease due to aging liver function.
- Fat content is increased due to decreased lean body mass.
- The number of intact nephrons decreases with age.
- Gastric pH is less acidic because of reduced hydrochloric acid production.
Cultural Assessment in Nursing
- A cultural assessment includes:
- Use of herbal remedies or traditional medicine.
- Dietary habits and preferences
- Language barriers.
- Religious beliefs.
Drug Polymorphism
- Drug polymorphism is influenced by:
- Inherited factors,
- Dietary and nutritional status,
- Cultural practices.
Medication Error Prevention and Response
- Nurses have a responsibility to listen to patients' concerns about medications.
- If a patient doubts a medication order, nurses should verify the order with the prescriber.
- When prescriber handwriting is illegible, the nurse should contact the prescriber for clarification.
- Asking a colleague, waiting for the prescriber to return, or querying the patient about home medications does not resolve the issue.
