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 A
Explanation
A. Tremors:
Tremors or shaking is a common symptom of hypoglycemia. When blood glucose levels drop too low, the body reacts by releasing hormones like adrenaline, leading to symptoms such as tremors, shakiness, and palpitations.
B. Bradycardia:
Bradycardia, or a slow heart rate, is not typically associated with hypoglycemia. Instead, hypoglycemia tends to stimulate the release of adrenaline, which can increase heart rate.
C. Vomiting:
Vomiting is not a classic manifestation of hypoglycemia. Nausea may occur, but vomiting is more commonly associated with conditions such as hyperglycemia or diabetic ketoacidosis.
D. Fruity odor on the client’s breath:
A fruity odor on the breath is more commonly associated with diabetic ketoacidosis (DKA) in individuals with diabetes mellitus, particularly when there is an accumulation of ketones in the body. It is not a typical manifestation of hypoglycemia.
Correct Answer is A
Explanation
A. Regular insulin:
Regular insulin, also known as short-acting insulin, is commonly used in the initial management of diabetic ketoacidosis. It has a relatively rapid onset of action, making it suitable for addressing the acute and severe nature of DKA.
B. Insulin detemir:
Insulin detemir is a long-acting insulin analog. It is not the preferred choice for addressing the acute insulin needs in DKA; instead, it is used for basal insulin requirements in the maintenance phase of diabetes management.
C. Insulin glargine:
Insulin glargine is a long-acting insulin analog used for basal insulin coverage. Like insulin detemir, it is not the first choice for addressing the acute insulin needs in the initial treatment of DKA.
D. NPH insulin:
NPH (Neutral Protamine Hagedorn) insulin is an intermediate-acting insulin. While it has a role in diabetes management, it is not the preferred choice for the initial treatment of DKA. NPH insulin has a slower onset and longer duration compared to regular insulin.
