Study Notes

Patient Safety in Medication Administration

Anaphylaxis: A severe hypersensitivity reaction involving immunoglobulin E and rapid release of mediators, potentially life-threatening.
Antihypertensives: Drugs prescribed to manage high blood pressure.
Geriatric Medicine: Specialized healthcare focusing on the treatment and care of elderly patients.
HIPAA: Legislation ensuring patient rights and privacy concerning their medical information.
Lavage: Medical procedure involving the irrigation or washing out of a cavity.
OSHA: Agency responsible for ensuring safe and healthy working conditions in the U.S.
Pediatric Medicine: Focused on the diagnosis and treatment of diseases in children.
Polypharmacy: Simultaneous use of multiple medications, raising risks of side effects and drug interactions.
Seven Rights of Medication Administration: Essential principles for safe drug delivery include the right patient, drug, dose, time, route, technique, and documentation.
Teratogens: Substances that can cause abnormal fetal development or birth defects.
Thrombolytics: Medications designed to dissolve blood clots.
Urticaria: Another term for hives, causing itchy, raised skin areas.

Administration Procedures and Considerations

Verification Process: Always confirm the patient's identity and medication details through multiple checks before administration.
Drug Storage: Organize drug samples by classification to streamline access and ensure proper handling.
Dose Confirmation: Clarify any uncertainties regarding prescribed doses before administration; do not proceed without confirmation.
Timing of Administration: Medication timing can influence effectiveness; for instance, sleeping aids are typically given at night.
Importance of Consistency: Certain medications, especially antibiotics and antiseizure medications, must be taken at regular intervals to maintain effective blood levels.
Dosing in Children: Dosages must be carefully calculated for children due to their size and metabolism.

Special Considerations in Patient Care

Pre-Test Preparation: Patients scheduled for tests should refrain from medications and remain NPO (nothing by mouth) after midnight.
Diabetes and NPO Status: Insulin should not be administered if the patient is NPO to avoid hypoglycemia.
Reasons for Medication Discontinuation: Include testing requirements, drugs being no longer necessary, or alternate prescriptions.

Route of Administration Abbreviations

PO: By mouth
IV: Intravenous
IM: Intramuscular
ID: Intradermal
SC: Subcutaneous

Adverse Effects and Documentation

Effects of Improper Administration: Errors in injection angles or techniques can lead to severe complications, including nerve damage.
Documentation Requirements: Accurate recording is necessary, including medication type, time, dose, route, lot number, expiration date, and any adverse reactions.

Medication Absorption Factors

Individual Factors: Patient's nutrition, weight, gender, and age all play crucial roles in drug efficacy and safety.
Special Considerations for Geriatric Patients: Age-related physiological changes can affect drug absorption, distribution, and metabolism, necessitating careful dose adjustments.
Children's Unique Needs: Pediatric patients have different absorption and metabolism rates, affecting drug administration. Adjustments are critical for neonates and infants due to their underdeveloped systems.

Environmental and Lifestyle Influences

Cigarette Smoking: Increases drug metabolism, potentially requiring higher doses for efficacy.
Occupational Exposures: Can lead to hepatic injury, impacting how medications are processed and increasing risks of accumulation and toxicity.

Ethical and Legal Concerns

Informed Consent: Patients must fully understand their treatment options and the implications of experimental drugs.
Patient Rights: Include the right to participate in treatment decisions, refuse treatment, and maintain privacy regarding health information.
Assault and Battery: Forcing medication upon a patient can be legally considered assault.

Special Populations and Considerations

Impact of Gender on Medications: Biological differences can influence drug absorption; men generally have higher muscle mass than women, affecting metabolism.
Cultural Sensitivity: Cultural beliefs can significantly affect patient adherence to medication regimens, with some preferring herbal remedies over conventional treatments.
Aging Effects on Drug Metabolism: The elderly may face complications such as toxicity due to decreased liver function and altered drug interactions as a result of polypharmacy.
