move fluid into an area that is physiologically unavailable.

correct imbalance in fluid and electrolytes.

expand intravascular volume.

Answer and Explanation

Correct Answer : A,D,E

Choice A rationale: Compensating for an ongoing problem affecting other fluid or electrolytes is a common rationale for IV therapy.

Choice B rationale: Increasing urine specific gravity to 1.045 is not a typical goal for IV therapy. IV therapy would decrease the urine specific gravity by diluting the urine with fluids.

Choice C rationale: Moving fluid into an area that is physiologically unavailable is not a primary goal of IV therapy. Physiologically unavailable areas are those that are separated from the rest of the body by a membrane or barrier, such as the cerebrospinal fluid, the intraocular fluid, or the pleural fluid. IV therapy does not cross these barriers and only affects the intravascular and interstitial spaces.

Choice D rationale: Correcting imbalance in fluid and electrolytes is a primary goal of IV therapy.

Choice E rationale: Expanding intravascular volume is a common goal of IV therapy, especially in cases of dehydration or hypovolemia.
