Which body system provides the cells of the body with nutrients?

Correct Answer: B

Rationale: The digestive system, breaks down food into nutrients (e.g., glucose) for cells, absorbed via intestines. Respiratory supplies oxygen, cardiovascular transports, endocrine regulates via hormones, and urinary excretes waste. Anatomically, digestion's nutrient extraction e.g., small intestine villi directly feeds cells, distinguishing B as the provider.

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.

Correct Answer: C

Rationale: The adrenal glands perch atop the kidneys, a superior position toward the head. Nurses monitor this for endocrine issues like adrenal fatigue relative to kidney placement. This cephalic orientation distinguishes it from lateral or distant terms, guiding precise anatomical and clinical focus.
