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.
