Which choice best describes the location of the majority of the musculo-skeletal system?

Correct Answer: D

Rationale: The musculo-skeletal system bones and muscles spans limbs, torso, and head, existing outside the body's major cavities. Unlike organs housed in dorsal or ventral spaces, it surrounds and supports these regions. Nurses assess it for injuries like fractures beyond cavity confines, focusing on its external framework role. This distribution ensures mobility and protection, distinct from cavity-bound systems, shaping care for structural integrity.

Correct Answer: A

Rationale: Anabolism builds complex molecules like proteins using energy, a constructive metabolic phase. Nurses see its effects in growth like muscle repair contrasting with breakdown or nutrient delivery processes. It's a key cellular activity, driving tissue formation and recovery, vital for understanding health and healing dynamics.

Correct Answer: D

Rationale: Abdominal regions like left hypochondriac, hypogastric, epigastric map the front, but right sacral' ties to the posterior pelvis, not the abdomen's anterior nine-zone grid. Nurses use these zones for organ localization like epigastric pain for stomach issues excluding sacral, which fits spinal or pelvic contexts.

Correct Answer: D

Rationale: Negative feedback stabilizes variables by reversing deviations blood pressure adjusts to exertion, glucose balances after meals, and pH corrects via breathing or kidney action. Each counters change to maintain set points, a common regulatory theme. Nurses manage these like insulin for glucose relying on this mechanism's prevalence to restore equilibrium, distinguishing it from amplifying processes and ensuring bodily consistency across systems.

Correct Answer: B

Rationale: The four principal tissue types are nervous, epithelial, muscle, and connective . Bone is a connective tissue subtype, not a principal category. Anatomically, connective tissue includes bone, cartilage, and blood, supporting diverse functions, while the four types classify broadly nervous conducts, epithelial covers, muscle moves excluding B as a standalone type.
