NHA CCMA Exam Prep 83, Difficult Draws and Unsuccessful Attempts

The exam will test your ability to handle complex venipuncture scenarios by presenting you with patients who have challenging veins, such as those that are small, rolling, fragile, sclerosed, or deep.

You'll often see these in geriatric, pediatric, obese, or chronically ill patients.

For instance, an exam question might describe an 85-year-old patient with hard, cord-like veins in the antecubital fossa.

This is a classic description of sclerosed veins, which can be caused by disease, chemotherapy, or repeated venipunctures.

The trick answer would be to proceed with a standard needle.

The correct answer is to recognize these veins are unsuitable and assess the other arm or consider using the dorsal part of the hand, which requires a different technique and equipment.

Patient condition is another key factor the exam will test.

A common scenario involves dehydration, which leads to decreased blood volume and makes veins harder to palpate and access.

If a question mentions a patient is dehydrated, your first thought should be about interventions to improve vein prominence.

While you can't always wait for them to rehydrate, you can apply a warm compress to the site for three to five minutes.

This is a crucial step that increases blood flow and can make a difficult vein much easier to access.

Positioning is also critical.

Having the patient lower their arm below the level of the heart uses gravity to help fill the veins.

Equipment selection is a frequent source of exam questions.

If you encounter a patient with small or fragile veins, especially on the hand or wrist, the NHA CCMA exam expects you to choose a winged infusion set, also known as a butterfly needle.

A typical question might ask for the most appropriate device for drawing from an elderly patient with delicate dorsal hand veins.

The correct choice is a 23-gauge winged set, not the standard 21-gauge straight needle, which would likely cause a hematoma or collapse the vein.
