What is the primary goal of homeostasis in the body?

Correct Answer: B

Rationale: Homeostasis aims to stabilize the body's internal conditions like blood sugar or temperature despite external shifts. This balance, maintained through feedback, is vital for cellular function and survival. Nurses track it to spot disruptions, intervening to prevent instability, underscoring its role as a health cornerstone.

Correct Answer: B

Rationale: Respiration transforms nutrients into energy via cellular processes, primarily in mitochondria, fueling bodily activities. Distinct from digestion's breakdown or excretion's waste removal, it's the energy engine. Nurses monitor its efficiency like in respiratory distress ensuring cells power life's demands seamlessly.

Correct Answer: B

Rationale: Arteries transport oxygen-rich blood from the heart to tissues, powering cellular function. Unlike veins or capillaries, they're built for pressure, driving circulation. Nurses track arterial health like in hypertension ensuring oxygen delivery supports bodily vitality.

Correct Answer: B

Rationale: The endocrine system secretes hormones to regulate processes like metabolism and growth. Distinct from circulatory or nervous roles, it's a chemical messenger network. Nurses monitor it like in diabetes ensuring hormonal balance maintains bodily harmony.

Correct Answer: A

Rationale: Epithelial tissue blankets surfaces and cavities like skin or gut lining protecting and absorbing. Unlike supportive or signaling tissues, it's a barrier and interface. Nurses assess it for breaches like ulcers ensuring its integrity safeguards underlying structures.
