Summary
A nurse-led educational program significantly improved diabetes knowledge in adults with Type 2 diabetes mellitus (T2DM). The intervention effectively addressed misconceptions and enhanced understanding of disease control and complications.
Area of Science:
- Endocrinology
- Public Health
- Nursing Education
Background:
- Type 2 diabetes mellitus (T2DM) is a growing global health concern, especially in low- and middle-income countries.
- Effective patient education is crucial for self-care, glycemic control, and complication prevention in T2DM management.
Purpose of the Study:
- To assess the impact of a nurse-led educational intervention on diabetes knowledge among adults with T2DM.
- To measure changes in knowledge using the Diabetes Knowledge Questionnaire (DKQ-24).
Main Methods:
- A quasi-experimental pre-post study design was employed.
- Thirty adult T2DM patients received a three-session educational program delivered by nurses.
- The DKQ-24 was administered pre- and post-intervention, with data analyzed using descriptive statistics and paired t-tests.
Main Results:
- The mean DKQ-24 score significantly increased from 24.1 to 26.4 (p = 0.0039).
- Significant knowledge improvements were observed in areas including special diets, wound care, and insulin production.
- The disease control and complications domain showed the most substantial knowledge gains, with nine items improving significantly.
Conclusions:
- A brief, nurse-delivered educational intervention effectively enhanced diabetes knowledge in T2DM patients.
- The intervention successfully dispelled common myths and misconceptions about diabetes management.
- Findings support integrating structured nursing education programs into routine clinical care for T2DM.

The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

01:24Nursing Process for Patient and Caregiver Teaching II: Planning and Implementation
1.4K
Planning for learning involves the development of a teaching plan. Teaching plans are similar to nursing care plans—both follow the steps of the nursing process. Planning in the teaching process involves setting goals and outcomes. Here, goals identify what a patient needs to achieve to understand a healthcare topic better, whereas the outcomes are the action to be performed by the patient to achieve the goal within a timeframe. For example, if the goal is to educate the patient about...

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.

The nursing process provides a clinical decision-making framework for patients and families to establish and implement a personalized care plan. Since part of the nurse's duties is to teach patients, the steps of the nursing process are the most effective way to approach instruction. The nursing process and the teaching-learning process are inextricably linked.

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...
