1:5
1:10

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.

Correct Answer is B
Explanation
A. Prone: The prone position (lying face down) is not suitable for venipuncture or for patients at risk of syncope.
B. Trendelenburg: The Trendelenburg position (lying flat with the legs elevated) can help prevent syncope by increasing venous return to the heart and improving blood flow to the brain.
C. Supine: While the supine position (lying flat on the back) is appropriate for venipuncture, the Trendelenburg position is preferred for patients with a history of syncope.
D. Fowler's: The Fowler's position (sitting or semi-sitting) is not suitable for preventing syncope during blood draws.
