As you are about to assist her to your cot, she asks you to wait because she feels the need to use the bathroom first. Which of the following is the BEST course of action?
A) Tell the patient she needs to be transported immediately and using the bathroom will have to wait until she arrives at the hospital.
B) Advise the patient that this could be an indication that the baby is ready to be born and you need to check to see if the baby's head is visible.
C) Allow the patient to use the bathroom as it will make transport, and also delivery, more comfortable.
D) Advise the patient that this could be a sign of a serious complication, have her lie on her left side, apply high-concentration oxygen, and transport immediately.
