A nurse is teaching students about the use of isotonic solutions. The nurse recognizes which statements made by a student about isotonic solutions are correct. (SELECT ALL THAT APPLY)
Is used to replace fluid loss
Usually do not provide calories
Does not expand intravascular volume
Mostly do not provide free water
Has the same osmolality as body fluids
Correct Answer : A,B,D,E
A. Is used to replace fluid loss.
Isotonic solutions, such as normal saline (0.9% NaCl) and lactated Ringer's solution, are used to replace fluid loss in situations such as dehydration, surgery, trauma, or other conditions where there is a need for fluid resuscitation.
B. Usually do not provide calories.
Isotonic solutions typically do not contain calories. They are designed primarily for fluid replacement and do not contribute to the nutritional needs of the patient.
C. Does not expand intravascular volume.
This statement is incorrect. Isotonic solutions are used to expand intravascular volume. When infused into the bloodstream, isotonic solutions help restore and maintain adequate blood volume. They do not cause significant shifts of fluids between compartments.
D. Mostly do not provide free water.
Isotonic solutions generally do not provide free water. They have the same osmolality as body fluids, meaning that they do not cause a net movement of water into or out of cells, and they maintain the osmotic balance.
E. Has the same osmolality as body fluids.
Isotonic solutions have the same osmolality as body fluids, which means they do not cause a net movement of water into or out of cells. This characteristic makes them suitable for situations where there is a need to expand intravascular volume without causing significant shifts in fluid compartments.

Correct Answer is D
Explanation
A. Applying a cold pack to the client's upper arm is not the first action. The priority is to assess and address the cause of the edema. Cold packs may be used for comfort, but they do not address the underlying issue.
B. Removing the PICC line is not the first action. Before considering removal, it is essential to assess the extent and cause of the edema. Removing the line without proper evaluation could lead to premature discontinuation of necessary treatment.
C. Notifying the provider who inserted the PICC line is important, but it is not the first action. The nurse needs to assess and intervene promptly. The provider should be informed after initial actions are taken.
D. Stopping the infusion and measuring the circumference of both upper arms is the first action. This helps determine the extent of the edema and whether it is related to the infusion. It is crucial to assess for complications such as infiltration or extravasation of the TPN solution.
Correct Answer is C
Explanation
A. Insulin glargine does not have a duration of 3 to 6 hours. This duration of action is much shorter than the actual duration of insulin glargine.
B. Insulin glargine does not have a duration of 14 to 22 hours. This duration is shorter than the typical duration of action for insulin glargine.
C. Insulin glargine, a long-acting insulin, has a duration of action that lasts approximately 24 to 36 hours. It provides a slow and steady release of insulin, offering a relatively consistent blood sugar-lowering effect over an extended period.
D. Insulin glargine does not have a duration of 6 to 10 hours. This duration is shorter than the actual duration of action for insulin glargine.
