1:5
1:10
1:15

B. 1:10: A 1:10 dilution of bleach to water is commonly used for disinfecting surfaces and cleaning medical equipment, as it provides effective disinfection while being safe for equipment.
C. 1:15: This dilution might not be strong enough to ensure effective disinfection.
D. 1:20: This ratio is even more diluted and may not provide adequate disinfectant strength for cleaning purposes.

C. Echocardiogram: An echocardiogram uses ultrasound to visualize the heart's structures and is not performed while the patient is exercising.
