Study Notes
Official Websites and Secure Connections
- Federal government websites typically end in .gov or .mil.
- Users should verify they are on a federal website by checking for https://, which indicates a secure connection and encryption of sensitive information.
Medication Administration Routes
- Routes are classified by the application site, such as oral, intravenous (IV), and others.
- Choice of administration route depends on drug properties, pharmacokinetics, convenience, and patient compliance.
- Understanding characteristics and techniques of each route is essential for effective medication delivery.
Interprofessional Healthcare Team
- Multiple healthcare team members play significant roles in medication administration.
- Recognizing unique contraindications for each administration route is crucial for patient safety.
- Collaborating interprofessionally optimizes medication route selection, improving patient outcomes.
Enteral Routes of Medication
- Oral Administration: Convenience and cost-effectiveness; primary absorption occurs in the small intestine.
- First-pass Effect: Metabolism in the liver reduces drug concentration before systemic circulation.
- Sublingual and Buccal Routes: Allow for bypassing first-pass metabolism via absorption directly into the bloodstream; sublingual provides faster absorption due to the highly permeable mucosa.
- Rectal Route: Rapid absorption via the rectal mucosa; circumvents first-pass metabolism but can cause irritation.
Parenteral Routes of Medication
- Intravenous (IV) Injection: Most common parenteral route; bypasses the first-pass effect.
- Common sites for IV access include veins in the upper extremity (e.g., basilic, cephalic veins) to minimize complications like thrombophlebitis.
- Intramuscular (IM) Route: Administered to various muscles; ventrogluteal site is preferred to avoid complications associated with dorsogluteal injections.
- Subcutaneous Injections: Administered below the dermis; slower absorption is characteristic due to fewer blood vessels in the subcutaneous tissue.
Other Routes of Medication
- Transnasal: Absorption through respiratory epithelium directly into systemic circulation.
- Inhaled Medications: Utilize a large surface area of the respiratory tract; effective for conditions requiring rapid absorption.
- Vaginal Route: Limited use; can avoid first-pass metabolism and deliver local/systemic therapy effectively.
- Transdermal Route: Involves skin delivery through patches or gels; useful for continuous dosing.
Administration Considerations
- Contraindications vary by route; oral routes may be unsuitable for patients unable to swallow, and IM injections may be avoided in cases of infection.
- Preparation emphasizes the "five rights": right patient, drug, dose, site, and timing.
- Proper techniques for various routes enhance patient comfort and medication efficacy.
Complications of Medication Administration
- Parenteral Complications: Pain, bleeding, bruising, risk of infection, and infiltration.
- Intramuscular Risks: Potential nerve injury, particularly in the deltoid or dorsogluteal regions.
- Subcutaneous Concerns: Volume limitations and site-specific issues.
- Healthcare personnel should monitor closely for complications and adverse effects of medications.
Techniques for Effective Delivery
- Use of a tourniquet may help visualize veins for IV access but must be removed before injecting.
- Rotating injection sites for subcutaneous medications helps prevent complications like lipohypertrophy.
- Inhalers require specific techniques for effective delivery; maintenance and cleaning are essential to avoid medication buildup.### Insulin Administration Complications
- Subcutaneous insulin can lead to lipohypertrophy or lipoatrophy, impairing insulin absorption at injection sites.
- Recommended practice includes rotating injection sites to mitigate these issues.
Intranasal Medication Risks
- Prolonged use of intranasal steroids may cause interseptal nasal perforation.
- Chronic use of nasal decongestants can lead to rebound congestion due to poor vasculature response.
Inhaled Medication Complications
- Inhaled corticosteroids may result in local deposition causing thrush, dysphonia, cough, throat irritation, and contact hypersensitivity.
- Complications are often specific to the medication used.
Interprofessional Healthcare Approach
- Understanding medication routes is critical for healthcare team members to ensure effective patient care.
- Knowledge of contraindications and complications aids in minimizing patient risks.
Medication Administration Routes
- Each route has distinct characteristics that influence patient management.
- Advanced skills are required for techniques like central venous catheter placement and PICC lines, necessitating proper communication and planning.
Patient Involvement in Care
- Involving patients in decision-making regarding self-administration routes improves outcomes.
- Awareness of cultural or personal barriers to certain routes is essential for healthcare personnel.
Documentation Importance
- Accurate documentation of medication routes is vital for record-keeping and informs the entire care team on therapy administration.
- This affects pharmacokinetic and pharmacodynamic parameters such as dosing and half-life.
Pain Management Strategies
- Minimizing discomfort during medication administration can enhance patient experience and outcomes.
- Use of local anesthetics for parenteral routes and lubricants for rectovaginal routes is recommended.
Monitoring for Complications
- Immediate and delayed complications following medication administration should be closely monitored, particularly for central venous catheters.
- Nursing staff must maintain catheter sterility and functionality while communicating issues effectively within the healthcare team.
Chemical Bonds Overview
- Chemical bonds connect atoms or ions to form molecules, crystals, and structures.
- Ionic bonds form from electrostatic attraction between oppositely charged ions.
- Covalent bonds arise from the sharing of electrons between atoms.
- Bonds can be classified as strong ("primary" bonds) or weak ("secondary" bonds).
Types of Chemical Bonds
- Strong bonds include:
- Covalent Bonds: Atoms share electrons, resulting in distinct directional bonds.
- Ionic Bonds: Electrons are transferred, creating charged ions that attract each other.
- Metallic Bonds: Atoms release electrons into a "sea," allowing for collective electron sharing.
- Weak bonds (e.g., dipole-dipole interactions, London dispersion forces, hydrogen bonding) generally result from non-covalent forces.
Bond Characteristics
- Bond distance is the optimal spatial arrangement of bonded nuclei, balancing attractive and repulsive forces.
- Electron sharing in covalent bonds can vary, leading to:
- Non-polar Covalent Bonds: Electrons are equally shared (electronegativity difference: 0 - 0.3).
- Polar Covalent Bonds: Electrons are unequally shared, resulting in a dipole (electronegativity difference: 0.3 - 1.7).
- Energy is released during bond formation, primarily due to lower kinetic energy associated with spatially distributed electrons.
Electronegativity and Bonding
- Electronegativity is the tendency of an atom to attract shared electrons, influencing bond type and energy.
- A significant difference in electronegativity indicates ionic character.
- Covalent bonds dominate organic compounds, while ionic bonds are prevalent in salts like sodium chloride.
Ionic Bonding
- Ionic bonding involves substantial electronegativity differences (typically >1.7).
- Ionic compounds form crystalline structures where ions are equally surrounded by opposing charges.
- When dissolved in water, ionic bonds break, allowing ions to move freely; covalent bonds remain intact.
Covalent Bonding
- Covalent bonding can involve:
- Single Bonds: Sharing of two electrons.
- Double and Triple Bonds: Sharing of more electrons (increases bond strength).
- Non-polar molecules are often insoluble in water, while polar molecules can form strong dipole interactions.
Bonding Models and Theories
- Various models describe bonds and molecular structures:
- Valence Bond Theory: Explains bonding through overlapping atomic orbitals.
- Molecular Orbital Theory: Considers electrons in a collective orbital framework.
- VSEPR theory helps predict molecular shapes based on electron pair repulsion.
Summary of Key Points
- Chemical bonds dictate the structure and properties of matter, enabling understanding of physical characteristics across substances.
- Bonding types—ionic, covalent, metallic—each impart unique properties to materials, influencing melting points, conductivity, and malleability.
