A coronal (frontal) plane divides the body into:

Correct Answer: A

Rationale: The coronal plane divides the body into front and back, isolating anterior from posterior regions. This orientation is vital for frontal assessments like chest exams offering a clear view of forward-facing structures. It enhances medical precision, guiding interventions by delineating these key anatomical zones.

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.

Correct Answer: D

Rationale: The humerus spans the upper arm, linking shoulder to elbow, supporting movement. Unlike leg or forearm bones, it's the arm's structural anchor. Clinicians focus here for fractures, ensuring its integrity restores arm function.
