Intravenous Infusion Lesson Objectives

Nurse's Responsibility in Intravenous Therapy

• Assess the patient's condition and determine the need for intravenous (IV) therapy.
• Obtain informed consent from the patient prior to starting IV therapy.
• Select appropriate IV sites and insert catheters using aseptic techniques.
• Monitor the IV site for complications such as infiltration, phlebitis, or infection.
• Administer IV medications, fluids, and blood products as prescribed.
• Document the IV therapy, including type of fluid, rate of infusion, and patient responses.
• Provide patient education regarding the purpose and care of the IV therapy.

Purpose of Intravenous Infusion

• Delivers fluids and electrolytes directly into the bloodstream for rapid absorption.
• Administers medications quickly and effectively, bypassing the digestive system.
• Facilitates the delivery of blood products in cases of significant blood loss.
• Maintains venous access for emergency situations requiring immediate treatment.
• Supports nutritional needs in patients unable to take oral intake.

Capillaries

• Smallest blood vessels in the body, connecting arterioles and venules.
• Responsible for the exchange of oxygen, carbon dioxide, nutrients, and waste products between blood and tissues.
• Walls are thin, allowing easy diffusion of substances.

Blood Vessels Carrying Blood Away from the Heart

• Arteries are the blood vessels responsible for transporting oxygenated blood away from the heart to the body.
• The aorta is the main artery, branching into smaller arteries throughout the body.

Intravenous Therapy in Hospitalized Patients

• Frequently used to ensure quick and efficient delivery of medications and fluids.
• Essential for patients who cannot eat or drink due to illness or surgery.
• Allows for precise fluid and electrolyte balance, crucial in critical care settings.
• Facilitates monitoring of patient responses and adjustments to treatment as necessary.

This quiz covers the objectives and content related to assisting in intravenous infusion, including defining intravenous infusion, explaining its purpose, differentiating types of intravenous fluids, and listing the equipment needed. It also involves the study of blood vessels and how blood is distributed.
