The nurse understands that the rationale(s) for clients receiving intravenous (IV) therapy is/are to: (SELECT ALL THAT APPLY)
compensate for an ongoing problem affecting other fluid or electrolytes.
Increase urine specific gravity to 1.045.
move fluid into an area that is physiologically unavailable.
correct imbalance in fluid and electrolytes.
expand intravascular volume.
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.

Choice A rationale: Under-delegation is not related to giving too much responsibility to assistive personnel; it is about appropriate delegation based on the nurse's assessment of the situation.
Choice B rationale: Trust in delegates is essential, and under-delegation is more likely related to a lack of trust or confidence in delegation.
Choice C rationale: Under-delegation can occur due to a nurse's need for perfectionism and control, leading to a reluctance to delegate tasks to others.
Choice D rationale: Nurses often have heavy workloads, and under-delegation may be a result of feeling there is not enough time to delegate effectively.
Correct Answer is C
Explanation
Choice A rationale: The deltoid muscle may not accommodate larger volumes as comfortably as other sites.
Choice B rationale: The dorsogluteal site is not recommended due to the risk of injury to the sciatic nerve.
Choice C rationale: The ventrogluteal site is the preferred site for IM injections in adults, providing a safe and well-vascularized muscle.
Choice D rationale: The vastus lateralis is a suitable site for infants and young children but may not be the most comfortable for adults receiving a 2 mL injection.
