Critical Thinking I01:24

Critical Thinking I

5.8K
Critical thinking helps decision-making and allows nurses to recognize barriers to success and find solutions to possible issues. It helps to brainstorm and implement ideas to achieve goals. Critical thinking helps acknowledge and state workflow inefficiencies while improving management techniques. Nurses understand the value of critical thinking and look for fellow nurses with critical thinking skills to upgrade their professional standards. Critical thinking can advance a nurse's career...

The Professional Nurse01:22

The Professional Nurse

7.2K
Professional nurses are not limited to bedside care and are taking roles of greater responsibility. A nurse should have a knowledge-based practice, including personal, theoretical, procedural, cultural, and reflexive knowledge. Additionally, nurses must be competent in cognitive, technical, interpersonal, and ethical/legal skills. Some of the best attributes of successful nurses include the following:
Communication skills: These are critical characteristics, especially speaking and listening.

Patient-centered Care01:13

Patient-centered Care

3.2K
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...

Current Trends in Nursing II

3.6K
Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Obedience01:08

Obedience

35.7K
According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...

Summary

This study found that lower work ability index (WAI) and cognitive failures (CFs) in nurses are linked to increased errors. Improving nurses' work ability and reducing cognitive failures are crucial for patient safety.

Area of Science:

  • Healthcare Quality
  • Nursing Practice
  • Occupational Health

Background:

  • Nursing errors significantly impact patient healthcare quality.
  • Nurses' focus and reduced cognitive failures are linked to compatible work conditions.
  • Investigating factors affecting nurses' work ability and cognitive failures is essential.

Purpose of the Study:

  • To examine the relationship between the Work Ability Index (WAI) and Cognitive Failures (CFs) in ICU, CCU, and emergency ward nurses.
  • To identify factors influencing WAI and CFs in critical care and emergency nursing settings.

Main Methods:

  • A descriptive-analytical, cross-sectional study involving 750 nurses.
  • Data collected using questionnaires on WAI and CFs.
  • Statistical analysis included Pearson and Spearman correlations, chi-squared, ANOVA, and Kruskal-Wallis tests.

Main Results:

  • A significant inverse relationship was found between WAI and CFs, including subscales.
  • CFs showed a significant positive correlation with age and experience.
  • WAI was inversely related to age, work experience, and BMI; both WAI and CFs were significantly related to working units.

Conclusions:

  • Nurses' WAI and cognitive status were below optimal levels.
  • Recommendations include pre-employment screening, optimized work-shift management, and engineering/administrative strategies to enhance work ability and reduce cognitive failures.
  • Improving nurse work ability and cognitive function is vital for ensuring patient safety in critical care and emergency settings.
