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 A
Explanation
A. Place the arm electrodes facing downward. The arm electrodes should be placed with the tabs facing downward to reduce the risk of artifacts on the EKG tracing caused by movement or improper lead contact.
B. Place the electrodes over bony prominences when possible. Electrodes should not be placed over bony prominences, as this can interfere with the accuracy of the EKG reading. Instead, they should be placed on soft tissue.
C. Place the leg electrodes downward. Leg electrodes should also be placed with the tabs facing downward to prevent artifacts, similar to the arm electrodes.
D. Place the chest electrodes in a straight line just below the nipple. Chest electrodes should be placed according to specific anatomical landmarks, not in a straight line, to ensure accurate heart rhythm tracing.
Correct Answer is D
Explanation
A. Sterile needle holder: A sterile needle holder is used in suturing, not for removing sutures, making it unnecessary for suture removal.
B. 1-mL syringe with an 18-gauge needle: This is used for injections, not for removing sutures. It is not required for a suture removal procedure.
C. 4-by-4-inch benzalkonium wipes: Benzalkonium wipes are used for skin antisepsis, but they are not specifically required for suture removal. While antiseptic wipes are useful, they are not essential for the procedure itself.
D. Sterile thumb dressing forceps: Sterile thumb dressing forceps are necessary for grasping and removing sutures safely without causing trauma to the wound. They are an essential tool for suture removal.
