Correct Answer is B

Explanation

Choice A rationale: Injecting air into the regular insulin and then into the NPH is not the correct sequence.

Choice B rationale: Injecting air into both vials and withdrawing the regular insulin first is the correct sequence when drawing up a combination of short-acting and intermediate- acting insulins.

Choice C rationale: Injecting air into and withdrawing the NPH immediately is not the correct sequence.

Choice D rationale: Withdrawing the regular insulin first is not the correct sequence when preparing a mixed insulin injection.

A. compensate for an ongoing problem affecting other fluid or electrolytes. B. Increase urine specific gravity to 1.045. C. move fluid into an area that is physiologically unavailable. D. correct imbalance in fluid and electrolytes. E. expand intravascular volume.

Correct Answer is ["A","D","E"]

Explanation

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.
