Answer:
D. 6.5
Explanation:
A vaginal exam for a woman perceived to be having ruptured membranes can be carried out by testing the pH value of the vaginal fluid collected.
The normal pH range of the vaginal is usually between 4.5 – 6.0. If the vaginal fluid tested shows a pH value that is above 6.5, it means the membrane of the woman probably must have ruptured. The amniotic fluid has a higher pH value between 6.5 to 7.5.
Ruptured membrane will give us a vaginal fluid pH value ranging from 6.5 and above.
