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. Calcium:
While calcium levels can be affected in pancreatitis, it is more commonly associated with a decrease in calcium levels due to fat necrosis and the formation of calcium soaps. However, the primary electrolyte disturbance is more likely to involve magnesium.
B. Magnesium:
Magnesium levels may be decreased in acute pancreatitis due to factors such as vomiting, malabsorption, and poor oral intake. Hypomagnesemia is a possible consequence, but it's not as specific to pancreatitis as the elevation of amylase.
C. Amylase:
Elevated amylase levels are a hallmark of acute pancreatitis. Amylase is an enzyme released by the pancreas, and its elevation in the blood is a key diagnostic marker for pancreatitis.
D. RBC count:
Acute pancreatitis does not typically result in a significant impact on the red blood cell (RBC) count. The elevation of amylase and lipase levels, along with imaging studies, is more indicative of pancreatitis.
Correct Answer is B
Explanation
A. Level of consciousness:
While assessing the client's level of consciousness is important, it is not the top priority after an EGD procedure unless there are specific signs of neurological distress. Monitoring for signs of sedation or anesthesia recovery is typically part of post-procedure care.
B. Gag reflex:
This is the correct answer. The nurse should prioritize assessing the gag reflex, as the procedure involves passing a flexible tube through the mouth and down the esophagus. Ensuring the return of the gag reflex is essential to prevent aspiration and ensure the client's safety.
C. Pain:
Pain assessment is important, but it is usually addressed after confirming airway protection and ensuring the absence of complications such as bleeding or perforation.
D. Nausea:
While nausea is a possible post-procedure symptom, assessing the gag reflex and monitoring for signs of complications take precedence over managing nausea in the immediate post-procedure period.
