A nurse is teaching a client diagnosed with type 1 diabetes mellitus about foot care. Which of the following statements by the client about foot care is correct?

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.

A. Warfarin:

Warfarin is an anticoagulant that works by inhibiting the synthesis of certain clotting factors, including factors II, VII, IX, and X. While it is used to prevent thromboembolic events, in a client with cirrhosis and an elevated PT, the priority is addressing the coagulation factor deficiency rather than adding an anticoagulant.

B. Vitamin K:

Vitamin K is the antidote for warfarin, and it helps in the synthesis of clotting factors. In cirrhosis, there can be impaired synthesis of clotting factors due to liver dysfunction. Administering vitamin K can aid in correcting coagulation abnormalities.

C. Heparin:

Heparin is another anticoagulant, but it does not reverse the effects of warfarin. It works by a different mechanism and is typically used in acute settings, such as deep vein thrombosis or pulmonary embolism. It is not the primary intervention for an elevated PT in cirrhosis.

D. Ferrous sulfate:

Ferrous sulfate is an iron supplement and is not indicated for the correction of an elevated PT. Iron supplements are typically used to address iron deficiency anemia.
