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 C
Explanation
A. The charge nurse should follow the staff closely and tell them every single thing they could possibly be doing wrong:
Micromanaging and focusing solely on the negatives can create a stressful and demoralizing work environment. This approach is less likely to motivate and inspire staff.
B. Make the staff aware that all errors will be severely punished:
A punitive approach to errors can create a culture of fear and may not foster a supportive environment for learning and improvement. It can lead to decreased morale and job satisfaction.
C. Acknowledge staff accomplishments when warranted and provide positive feedback:
This is the most effective approach. Recognizing and acknowledging staff achievements, providing positive feedback, and celebrating successes contribute to a positive work environment. It motivates staff to continue their efforts and fosters a culture of teamwork and collaboration.
D. Provide negative feedback with all errors:
While constructive feedback is essential for learning and improvement, a balance between constructive criticism and positive reinforcement is crucial. Constant negative feedback without recognition of positive efforts can lead to decreased morale.
Correct Answer is C
Explanation
A. Positioning the client on the right side is not a standard recommendation for gastric lavage. The standard position is typically on the left side to facilitate the drainage of gastric contents.
B. Instilling 1000 mL of sterile saline is not a recommended action for gastric lavage. Gastric lavage involves the removal of stomach contents rather than instilling fluids.
C. Withdrawing fluid until it is clear is the correct action. Gastric lavage is a medical procedure used to empty the stomach contents. The process involves introducing small amounts of fluid (such as saline) into the stomach and then aspirating it back, along with gastric contents, until the aspirate is clear.
D. Connecting the NG tube to high continuous suction is not a standard approach for gastric lavage. Gastric lavage involves intermittent instillation and withdrawal of small amounts of fluid to clear the stomach.
