A medical assistant should encourage patients to wear masks when which of the following respiratory infections is prevalent?
Influenza
Legionnaires' disease
Cystic fibrosis
Laryngitis
The Correct Answer is A
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 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.

A. Bone density test: Bone density tests are typically recommended for women starting around age 65 or earlier if risk factors are present, but they are not usually performed annually.
B. Dilated eye exam: While dilated eye exams are important, they are generally recommended every 1-2 years, not annually, unless specific conditions warrant more frequent exams.
C. Papanicolaou (Pap) test: The Pap test is recommended every 3 years for women aged 21-65 or every 5 years with HPV testing for those aged 30-65. Annual documentation is not required, but it is important to monitor this screening as part of preventative care.
