Which plane divides the human body into dorsal (back) and ventral (front) or posterior and anterior planes?

Correct Answer: B

Rationale: The coronal plane, divides the body into dorsal (back) and ventral (front), or posterior and anterior sections. Sagittal splits left-right, transverse/horizontal (C, D) upper-lower, and superior isn't a plane. This frontal plane is vital in anatomy for visualizing front-back relationships e.g., sternum anterior to spine used in cross-sectional studies like MRI, confirming B.

Correct Answer: C

Rationale: Situated beneath the right rib cartilage, this organ dominates the upper right abdomen, performing critical roles in detoxification and nutrient processing. Its location below the costal margin places it in the right hypochondriac zone, a key anatomical landmark. Nurses assess this area for conditions like hepatitis, where tenderness or enlargement signals issues. Its position contrasts with organs on the left or more central, making it a focal point for understanding abdominal anatomy and tailoring care to region-specific health needs.

Correct Answer: C

Rationale: The anatomical position is a standardized stance standing upright, arms at sides, palms forward showing the body's front. It's the reference for all directional terms, ensuring consistency in medical descriptions. Nurses use it to orient assessments like locating anterior chest pain contrasting with prone or spread postures. This universal pose simplifies communication, aligning anatomical landmarks for precise diagnostics and care across practitioners.

Correct Answer: A

Rationale: The heart resides above the large intestine, a true superior relationship given its thoracic versus abdominal placement. This guides clinicians in separating chest from gut issues like heartburn versus colitis. Other options falter: shoulders are nearer than hand bones, fingers extend past wrist bones, and eyes flank the nose laterally. Nurses leverage such accuracy for precise anatomical navigation.

Correct Answer: B

Rationale: The dorsal cavity encircles the brain and spinal cord, protecting the nervous system's core along the back. Nurses monitor this for trauma like concussions excluding ventral organs like the heart or kidneys. This focus distinguishes it from other cavities, ensuring care targets the neurological backbone effectively.
