Which of the following should a medical assistant recognize as an indication to prematurely terminate a patient's exercise stress test?

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. Label the tube after collection, including the date and time of collection: Labels should be applied to the tube immediately after the sample is collected to ensure accuracy and prevent mix-ups. Including the date and time helps with tracking and documentation.
B. Label the tube after collection, including the provider's name: While it is important to include identifying information, the primary focus should be on the date and time of collection to ensure the sample's accuracy.
C. Label the tube prior to collection, including the date and time of collection: Labels should be applied after the collection to avoid potential errors and ensure the correct sample is labeled.
D. Label the tube prior to collection, including the provider's name: Labeling prior to collection may lead to mistakes if the wrong sample is placed in the labeled tube. The correct practice is to label after collection.
