Nursing Interventions I: Taxonomy of Nursing Interventions

3.9K
Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Nursing Interventions II: Selecting and Classifying the Nursing Interventions

3.4K
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:

Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

680
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

601
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

554
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Summary

Left ventricular assist device (LVAD) implantation for advanced heart failure is common. Unrepaired mitral regurgitation during LVAD surgery may increase mortality, despite traditional guidelines suggesting it be left untreated.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Medical Devices

Background:

  • Left ventricular assist device (LVAD) implantation is a key therapy for advanced heart failure.
  • Current guidelines recommend against repairing mitral regurgitation during LVAD surgery.
  • Emerging evidence suggests unrepaired mitral regurgitation may be linked to adverse outcomes post-LVAD.

Purpose of the Study:

  • To evaluate the impact of unrepaired mitral regurgitation on outcomes following LVAD implantation.
  • To address the discrepancy between existing guidelines and new evidence regarding mitral regurgitation management in LVAD patients.
  • To highlight the challenges in assessing mitral valve pathology in LVAD patients.

Main Methods:

  • Review of recent evidence and clinical outcomes related to mitral regurgitation in LVAD patients.
  • Analysis of factors contributing to practice variability in mitral valve management during LVAD procedures.
  • Discussion of technical difficulties in transesophageal echocardiography for mitral valve assessment in LVAD recipients.

Main Results:

  • Mitral regurgitation may not resolve after LVAD implantation.
  • Unrepaired mitral regurgitation is associated with potentially worse patient outcomes.
  • There is significant variability in clinical practice regarding mitral valve repair during LVAD surgery.

Conclusions:

  • The management of mitral regurgitation during LVAD implantation requires careful consideration due to potential negative impacts on perioperative mortality.
  • Further research is needed to clarify optimal strategies for mitral valve management in LVAD candidates.
  • Improved echocardiographic techniques may be necessary for accurate mitral valve assessment in the presence of LVADs.
