Summary
Ensuring safe parenteral nutrition (PN) administration requires standardized competency assessment for nurses. This document proposes a framework to guide healthcare institutions in developing and maintaining PN administration competency for staff.
Area of Science:
- Healthcare Administration
- Clinical Nursing Practice
- Patient Safety
Background:
- Parenteral nutrition (PN) is a complex medication therapy.
- PN administration is susceptible to various errors.
- Standardized competency demonstration is crucial for safe PN therapy.
Purpose of the Study:
- To propose a standardized model for assessing PN administration competency.
- To guide healthcare institutions in developing PN competency tools and procedures.
- To enhance the safe administration of PN therapy.
Main Methods:
- Development of a competency framework.
- Integration of ASPEN interdisciplinary core competencies.
- Incorporation of discipline-specific standards and clinical guidelines.
Main Results:
- A proposed standardized model for PN administration competency.
- Guidance for institutions to develop and maintain staff competency.
- A framework approved by the ASPEN Board of Directors.
Conclusions:
- Standardized competency assessment is essential for safe PN administration.
- The proposed framework provides a roadmap for healthcare institutions.
- Implementation of this framework aims to reduce PN-related errors.

01:25Routes of Drug Administration: Parenteral
3.0K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

02:11The Roles of Bacteria and Fungi in Plant Nutrition
47.4K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

01:24Parenteral Anesthetics: Overview
772
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

01:12One-Compartment Open Model for Extravascular Administration: Zero-Order Absorption Model
386
Extravascular administration, such as oral or intramuscular routes, is a non-invasive drug delivery method, often preferred for ease and patient compliance. A key factor here is absorption, which dictates how quickly and effectively the drug enters the bloodstream from the administration site. Absorption follows either zero-order or first-order kinetics.
Zero-order absorption maintains a steady rate irrespective of the amount of drug left to be absorbed, making it a constant process. In the...

01:12Two-Compartment Open Model: Extravascular Administration
690
The two-compartment model for extravascular administration represents a drug's absorption and distribution process. It features a central compartment, where the drug is first absorbed, and a peripheral compartment, which illustrates the drug's distribution throughout the body. The rate of change in drug concentration in the central compartment is calculated by three exponents: absorption, distribution, and elimination.
The absorption exponent (ka) indicates the speed at which the drug...

01:29Drug Delivery: Parenteral Route
1.8K
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
