B. Performing a heel stick on an infant: This procedure is often performed by medical assistants, especially in a pediatric setting, as it is part of routine blood collection practices.

 

C. Drawing blood for a glucose tolerance test: Medical assistants are usually trained to perform blood draws, including for glucose tolerance tests.

 

D. Performing venipuncture with a winged collection device:  Medical assistants are generally trained to perform venipunctures, including using winged collection devices (butterfly needles)

Correct Answer is B

Explanation

A. "Avoid alcohol for 48 hours prior to the test.": While avoiding alcohol may be generally recommended for some tests, fasting is the primary requirement for a glucose tolerance test (GTT).

B. "Do not eat for 8 hours prior to the test.": A GTT typically requires fasting for 8-12 hours to accurately measure glucose levels.

C. "Limit physical exertion for 24 hours prior to the test.": Physical exertion is not typically a specific concern for a GTT, but fasting is essential.

D. "Eat a high carbohydrate meal 3 hours prior to the test.": A high carbohydrate meal is not required; fasting is necessary before the test.

Correct Answer is C

Explanation

A. 1/4 inch: A 1/4 inch border is too small to be considered a standard contaminated area. The correct border size is larger.

B. 1/2 inch: A 1/2 inch border is also not standard; the correct contaminated border is larger.

C. 1 inch: The standard for sterile fields is to consider a 1-inch border around the edge of the sterile field as contaminated. This helps to prevent inadvertent contamination of sterile items.

D. 1 1/2 inches: A 1 1/2 inch border is unnecessarily large and exceeds the standard 1-inch margin considered contaminated.
