Answer and Explanation

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. Fatty stools:

Obstruction of the common bile duct can result in impaired bile flow, leading to a decrease in bile salts reaching the intestine. This can result in the malabsorption of fats, causing fatty or greasy stools (steatorrhea).

B. Tenderness in the left upper abdomen:

Tenderness in the left upper abdomen might be more commonly associated with conditions like splenic issues or stomach problems rather than an obstruction of the common bile duct.

C. Straw-colored urine:

Straw-colored urine is typical of well-hydrated individuals and might not directly correlate with an obstruction of the common bile duct.

D. Ecchymosis of the extremities:

Ecchymosis (bruising) of the extremities is not typically associated with an obstruction of the common bile duct resulting from chronic cholecystitis.

A. Investigate the client's emotional concerns. B. Check the client's perianal skin integrity. C. Obtain a dietary history from the client. D. Review the client's electrolyte values.

Correct Answer is D

Explanation

A. Investigate the client's emotional concerns:

While addressing emotional concerns is important, assessing electrolyte imbalances and physiological stability takes precedence in managing an acute exacerbation of ulcerative colitis.

B. Check the client's perianal skin integrity:

Assessing perianal skin integrity is crucial, especially in inflammatory bowel disease, but it might not be the immediate priority compared to evaluating electrolyte imbalances.

C. Obtain a dietary history from the client:

Although dietary history is relevant for managing ulcerative colitis, the urgency lies in assessing and managing potential electrolyte imbalances due to the exacerbation of the condition.

D. Review the client's electrolyte values:

This is the correct action. During an acute exacerbation of ulcerative colitis, the client is at risk of electrolyte imbalances due to diarrhea, dehydration, and potential fluid and electrolyte losses. Promptly reviewing the electrolyte values helps identify any imbalances that might require immediate intervention.
