Which of the following is the size of the border around the edge of a Mayo tray that is considered contaminated in a sterile field?
1/4 inch
1/2 inch
1 inch
1 1/2 inches
The Correct Answer is C
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.

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.
Correct Answer is D
Explanation
A. An adult patient is watching a demonstration on the proper use of a meter-dose inhaler: This is related to managing a respiratory condition, not directly to communicable disease prevention.
B. An adult patient is being shown how to safely lift a heavy object: This pertains to body mechanics and injury prevention, not communicable disease prevention.
C. An older adult patient is listening to an explanation of risks and benefits of the flu vaccine: Although the flu vaccine helps prevent disease, the specific focus is not directly on communicable disease prevention strategies.
D. A school-age patient is being taught about cough etiquette: Teaching cough etiquette is a direct method of preventing the spread of communicable diseases.
