A medical assistant should encourage patients to wear masks when which of the following respiratory infections is prevalent?

A.

Influenza

B.

Legionnaires' disease

C.

Cystic fibrosis

D.

Laryngitis

Answer and Explanation

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. Taking aspirin within 12 hr of testing: Aspirin does not generally affect spirometry results.

B. Using sedatives within 1 hr of testing: Sedatives may affect respiratory function, but they are not a common consideration for spirometry preparation.

C. Exercising 2 hr prior to testing: Exercise can affect lung function temporarily, so it’s best to avoid vigorous exercise before a spirometry test.

D. Eating a heavy meal 4 hr prior to testing: While eating a heavy meal might cause some discomfort, it is less likely to affect the spirometry results significantly compared to exercise.

Correct Answer is B

Explanation

A. Wipe away the first five drops of blood after puncturing: Only the first drop of blood should be wiped away to remove any tissue fluid, not the first five drops.

B. Apply even pressure to the finger during the collection: Applying even pressure helps to promote blood flow without causing hemolysis or excessive squeezing, which could affect test results.

C. Puncture the index finger at the tip: The recommended site for a capillary puncture is the side of the middle or ring finger, not the tip of the index finger.

D. Puncture parallel to the fingerprint: The puncture should be made perpendicular to the fingerprint ridges to ensure an adequate blood flow and reduce the risk of blood running along the ridges.
