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 B
Explanation
A. Atorvastatin: Atorvastatin is a statin medication used to lower cholesterol levels. It is not known to cause glucose intolerance.
B. Prednisone: Prednisone is a corticosteroid and can cause glucose intolerance by increasing blood glucose levels. Corticosteroids can lead to insulin resistance, impaired glucose utilization, and increased gluconeogenesis.
C. Ranitidine: Ranitidine is an H2 receptor antagonist used to reduce stomach acid production. It is not known to cause glucose intolerance.
D. Guaifenesin: Guaifenesin is an expectorant used to help loosen mucus in the airways. It is not known to cause glucose intolerance.
Correct Answer is C
Explanation
A. "Wear compression stockings daily":
Compression stockings are not directly related to preventing the complications of retinopathy and nephropathy in diabetes. They are more commonly recommended for managing conditions like venous insufficiency and preventing blood clots.
B. "Have an eye examination once per year":
While regular eye examinations are important for monitoring and early detection of diabetic retinopathy, maintaining stable blood glucose levels is more directly related to preventing the progression of retinopathy.
C. "Maintain stable blood glucose levels":
This is the correct instruction. Stable blood glucose levels are crucial in preventing and minimizing the long-term complications of diabetes, including retinopathy (damage to the retina) and nephropathy (kidney damage). Consistent blood glucose control is key to reducing the risk of complications.
D. "Examine your feet carefully every day":
Daily foot examinations are essential for preventing diabetic foot complications, including ulcers and infections. While important for overall diabetes management, foot care is not specifically directed at preventing retinopathy and nephropathy.
