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 B

Explanation

A. Testing the client's emesis for blood is an important assessment, but assessing orthostatic blood pressure is a priority. Orthostatic blood pressure measurement helps identify if the client is experiencing significant blood loss, as changes in blood pressure upon standing may indicate hypovolemia.

B. Assessing orthostatic blood pressure is the priority action. Orthostatic hypotension can be a sign of decreased circulating blood volume, which is a concern in clients with gastrointestinal bleeding.

C. Explaining the procedure for an upper gastrointestinal series is not the first priority. While diagnostic tests may be needed, addressing the immediate concern of potential hypovolemia takes precedence.

D. Administering pain medication is not the first action. The priority is to assess and address the potential complications of gastrointestinal bleeding, such as hypovolemia.

A. "Wear compression stockings daily." B. "Have an eye examination once per year." C. "Maintain stable blood glucose levels." D. "Examine your feet carefully every day."

Correct Answer is C

Explanation

A. "Wear compression stockings daily":

Compression stockings are not directly related to preventing the complications of retinopathy and nephropathy in diabetes. They are more commonly recommended for managing conditions like venous insufficiency and preventing blood clots.

B. "Have an eye examination once per year":

While regular eye examinations are important for monitoring and early detection of diabetic retinopathy, maintaining stable blood glucose levels is more directly related to preventing the progression of retinopathy.

C. "Maintain stable blood glucose levels":

This is the correct instruction. Stable blood glucose levels are crucial in preventing and minimizing the long-term complications of diabetes, including retinopathy (damage to the retina) and nephropathy (kidney damage). Consistent blood glucose control is key to reducing the risk of complications.

D. "Examine your feet carefully every day":

Daily foot examinations are essential for preventing diabetic foot complications, including ulcers and infections. While important for overall diabetes management, foot care is not specifically directed at preventing retinopathy and nephropathy.
