Anterior
Posterior
Lateral
Medial
The Correct Answer is A
A. Anterior: The term "anterior" refers to the front of the body, so it is appropriate for describing a rash on the front of the patient's arm.
B. Posterior: "Posterior" refers to the back of the body, which is not the location of the rash in this scenario.
C. Lateral: "Lateral" refers to the side of the body. While the rash may be on the side of the arm, it is more specifically described as anterior.
D. Medial: "Medial" refers to the midline of the body, not specifically to the front of the arm.

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.
