Cognition is fundamental to nursing practice for several reasons. Firstly, it affects clinical decision-making. Nurses must process vast amounts of information rapidly and accurately to make informed decisions. Secondly, cognitive abilities influence communication with patients, families, and other healthcare professionals. Effective communication is essential for understanding patient needs and providing appropriate care. Lastly, cognition is critical for patient education. Nurses often educate patients about their conditions, treatments, and self-care practices, which requires clear and understandable explanations.
