A nurse is preparing to insert an IV catheter for an adult client. Which of the following actions should the nurse take?
Place the tourniquet above the proposed insertion site.
Place the extremity in a dependent position.
Choose the most proximal site on the extremity selected.
Apply a cool compress for several minutes before insertion of the IV catheter.
The Correct Answer is A
Choice A reason:
When preparing to insert an IV catheter, placing the tourniquet above the proposed insertion site helps facilitate venous distension and makes it easier to locate a suitable vein for the catheter insertion. This technique helps to improve visibility and access to the vein.
Choice B reason:
Placing the extremity in a dependent position (lower than the heart) can increase venous pressure and make it more difficult to insert the catheter.
Choice C reason:
Choosing the most proximal site on the extremity is not always necessary or appropriate. Veins distal to the proposed insertion site should be considered first, as they tend to be smaller and less accessible.
Choice D reason:
Applying a cool compress is not typically done before IV catheter insertion. It might cause vasoconstriction and make it more difficult to access a suitable vein.

Correct Answer is C
Explanation
Choice A reason:
ALT is not primarily used to check kidney function. Kidney function is typically assessed through other tests, such as blood urea nitrogen (BUN) and creatinine levels.
Choice B reason:
ALT is not used to assess the risk of blood clots. It is specifically related to liver function.
Choice C reason:
Alanine aminotransferase (ALT) is an enzyme found primarily in the liver. An elevated ALT level in the blood can indicate potential liver damage or disease, so the ALT test is used to assess the function of the liver.
Choice D reason:
ALT is not a test to determine heart performance. Heart function is evaluated using tests such as electrocardiograms (ECGs) or cardiac enzymes.
Correct Answer is D
Explanation
Choice A reason:
Soaking feet in warm water daily is not recommended for individuals with diabetes, as it can increase the risk of skin maceration and infection. People with diabetes should be cautious about foot care practices that involve prolonged moisture exposure.
Choice B reason:
Placing an oval corn pad over the toes with corn and removing it weekly may not be the best approach, as it can increase pressure on the area and potentially cause further skin irritation.
Choice C reason:
Using over-the-counter liquid medication to remove corns is not recommended for individuals with diabetes, as it can cause skin irritation, burns, or infection. It's important for individuals with diabetes to seek professional guidance for proper foot care.
Choice D reason:
"I can apply lotion to soften calluses as long as I don't put lotion between my toes." This is the correct statement. This statement indicates an understanding of proper care for corns and calluses. Applying lotion to soften calluses can help reduce discomfort, but it's important to avoid putting lotion between the toes to prevent excess moisture build-up that could lead to skin breakdown or infection.
