Nursing Process for Patient and Caregiver Teaching III: Evaluation and Documentation

2.6K
Evaluation of the teaching process enables the nurse to determine if the patient's learning needs were met and if training was effective. If the expected outcomes are not met, the care plan is revised, and additional education or reinforcement is provided. Nurses can ask questions after the session or obtain feedback to assess the patient's understanding of the topic.
Nurses can use several methods to evaluate patient outcomes. For example, oral questions can assess cognitive learning,...

Self-Evaluation: Self-Enhancement and Self-Verification

5.8K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Patient-centered Care01:13

Patient-centered Care

3.0K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Nursing Evaluation01:15

Nursing Evaluation

4.3K
The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

Drug Dosing: Geriatric Patients

269
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Drug Dosing: Obese Patients

263
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Area of Science:

  • Neurology
  • Interventional Neuroradiology
  • Emergency Medicine

Background:

  • Acute ischemic stroke with large vessel occlusion (LVO) in the anterior circulation has seen significant treatment advancements.
  • Mechanical thrombectomy has demonstrated substantial benefits within 6 hours and up to 24 hours in selected patients.
  • Imaging plays a critical role in patient selection, particularly in later time windows, using criteria like small ischemic core size.

Purpose of the Study:

  • To summarize the current state of mechanical thrombectomy for acute ischemic stroke with LVO.
  • To highlight the importance of imaging in patient selection for thrombectomy.
  • To identify unanswered questions and future research directions in LVO treatment.

Main Methods:

  • Review of recent clinical trials and guidelines on mechanical thrombectomy for LVO.
  • Emphasis on the role of advanced neuroimaging techniques (CT perfusion, DWI-MRI) for ischemic core assessment.
  • Discussion of clinical scoring scales for rapid patient identification and routing.

Main Results:

  • Mechanical thrombectomy is a highly effective treatment for acute ischemic stroke with LVO within established time windows.
  • Strict imaging criteria are essential for selecting patients, especially for extended time windows (up to 24 hours).
  • Ongoing trials are investigating further applications, including distal occlusions, mild deficits, and optimal anesthesia.

Conclusions:

  • Mechanical thrombectomy has revolutionized acute ischemic stroke care for LVO patients.
  • Future research will likely expand treatment indications and explore adjunctive therapies like neuroprotection.
  • Continued investigation is needed to address remaining clinical questions and optimize patient selection and outcomes.
