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 C

Explanation

A. "I'll wear sandals in warm weather":

While wearing sandals in warm weather can be comfortable, it may not provide adequate protection for the feet, especially for individuals with diabetes. Closed, protective shoes are generally recommended to prevent injuries.

B. "I'll put lotion between my toes after drying my feet":

Applying lotion between the toes can create a moist environment, which may increase the risk of fungal infections. It is generally advisable to keep the skin between the toes dry to prevent infections.

C. "I'll check my feet every day for sores and bruises":

This statement is correct. Regular foot checks are crucial for individuals with diabetes to identify any signs of sores, bruises, or other abnormalities early. Early detection and prompt treatment can help prevent complications.

D. "I’ll soak my feet in cool water every night before I go to bed":

Soaking the feet in cool water is generally not recommended, as it can lead to maceration of the skin and increase the risk of fungal infections. Daily inspection and proper hygiene are more important aspects of foot care.

A. Apply a cold pack to the client's upper arm. B. Remove the PICC line. C. Notify the provider who inserted the PICC line. D. Stop the infusion and measure the circumference of both upper arms.

Correct Answer is D

Explanation

A. Applying a cold pack to the client's upper arm is not the first action. The priority is to assess and address the cause of the edema. Cold packs may be used for comfort, but they do not address the underlying issue.

B. Removing the PICC line is not the first action. Before considering removal, it is essential to assess the extent and cause of the edema. Removing the line without proper evaluation could lead to premature discontinuation of necessary treatment.

C. Notifying the provider who inserted the PICC line is important, but it is not the first action. The nurse needs to assess and intervene promptly. The provider should be informed after initial actions are taken.

D. Stopping the infusion and measuring the circumference of both upper arms is the first action. This helps determine the extent of the edema and whether it is related to the infusion. It is crucial to assess for complications such as infiltration or extravasation of the TPN solution.
