Which of the following conditions is a cause for specimen rejection for a routine urinalysis?

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.

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.
