Final answer:
The correct statement about growth and development is that developmental tasks are age-related achievements, with development being a lifelong process encompassing qualitative changes in cognitive, emotional, and psychosocial domains.
Step-by-step explanation:
The correct statement about growth and development is that developmental tasks are age-related achievements. This aligns most accurately with the nurse's understanding of human development across the lifespan.
Growth often refers to quantitative changes in the body such as increases in height and weight. In contrast, development encompasses a broader spectrum, including qualitative changes that are cognitive, emotional, and psychosocial in nature. Development does not end with adolescence but rather continues throughout an individual's life. Cognitive theories do not exclusively focus on emotional development, but rather on aspects such as learning, reasoning, and memory processes. Developmental psychologists view growth and development as a lifelong process across three domains: physical, cognitive, and psychosocial, arguing that these can be scientifically studied throughout a person's life.
