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. Understanding
