A.

Reaching over the field

B.

Maintaining a 1-inch border around the edge of the sterile field

C.

Holding all sterile articles at waist level

D.

Facing the sterile field

Answer and Explanation

The Correct Answer is A

A. Reaching over the field: Reaching over a sterile field can contaminate it by introducing microorganisms from outside the sterile area.

 

B. Maintaining a 1-inch border around the edge of the sterile field: Maintaining a 1-inch border is a standard practice to ensure that the edges of the sterile field are not contaminated.

 

C. Holding all sterile articles at waist level: Holding sterile articles above the waist level is the recommended practice to prevent contamination. Holding them at waist level is considered acceptable as long as the items do not touch non-sterile surfaces.

 

D. Facing the sterile field: Facing the sterile field while working is part of maintaining sterile technique, as it ensures that you do not accidentally move toward the sterile field and contaminate it.

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 A

Explanation

A. Influenza: Influenza is a contagious respiratory infection that spreads through respiratory droplets. Wearing a mask can help prevent the spread of the virus, especially in public settings or during an outbreak.

B. Legionnaires' disease: Legionnaires' disease is a bacterial infection caused by inhaling aerosolized water contaminated with Legionella bacteria. It is not typically spread from person to person, so mask-wearing is not a usual precaution.

C. Cystic fibrosis: Cystic fibrosis is a genetic condition that affects the lungs but is not contagious. Patients with cystic fibrosis are not required to wear masks to prevent spreading it to others.

D. Laryngitis: Laryngitis is usually caused by viral infections or strain on the vocal cords. It is not typically contagious enough to warrant mask use.
