1. Define homeostasis and explain its importance in
maintaining physiological stability. (Answer: Homeostasis
refers to the body's ability to maintain a stable internal
environment despite external changes. It is crucial for the
optimal functioning of various systems and organs in the
body, ensuring that physiological processes occur within
narrow ranges for optimal health.)
Rationale: This question assesses the students'
understanding of the concept of homeostasis and its
significance in maintaining physiological stability, which is
fundamental knowledge for nursing practice.
2. Describe the role of negative feedback in maintaining
homeostasis, using specific examples. (Answer: Negative
feedback is a regulatory mechanism that counteracts any
change from the desired set point in order to restore
homeostasis. For instance, when blood glucose levels
become elevated, the pancreas secretes insulin, which
facilitates the uptake of glucose by cells, thereby lowering
blood sugar levels.)
Rationale: This question evaluates the students'
comprehension of negative feedback mechanisms and their
ability to provide relevant examples. UnderstandingÂÂ
