The fluid portion of blood is called:

Correct Answer: C

Rationale: Plasma , is blood's fluid portion, comprising water, proteins, and electrolytes, excluding cells like platelets. Interstitial and tissue fluid surround cells, intracellular is within. Anatomically, plasma (55% of blood) carries nutrients and waste, critical for circulation, making E the precise term.

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: B

Rationale: This field examines how body parts operate how lungs breathe or muscles contract unveiling life's mechanics. It's distinct from tissue-level study or chemical processes, focusing on functional dynamics. Nurses apply this to understand healthy operations like circulation supporting interventions when functions falter. It's the science of how,' critical for maintaining or restoring bodily performance.

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.
