A medical assistant is preparing to place lower-limb electrodes on a patient who has a left above the knee amputation. Which of the following actions should the assistant take when placing the lower-limb electrodes?

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.

A. Administering IV medication: Administering intravenous (IV) medication is typically within the scope of practice for registered nurses (RNs) due to the complexity and need for careful monitoring.

B. Performing a heel stick on an infant: This procedure is often performed by medical assistants, especially in a pediatric setting, as it is part of routine blood collection practices.

C. Drawing blood for a glucose tolerance test: Medical assistants are usually trained to perform blood draws, including for glucose tolerance tests.

D. Performing venipuncture with a winged collection device: Medical assistants are generally trained to perform venipunctures, including using winged collection devices (butterfly needles).
