A. Feet first, side rails upExplanation
When transporting a patient to the OR department, the stretcher should be oriented with the patient's feet first and the side rails up. This ensures that the patient's head is closer to the healthcare providers, allowing for better monitoring and communication during transportation. Additionally, having the side rails up provides a safety measure to prevent the patient from accidentally falling off the stretcher during movement.Rate this question:

Which of the following routines preoperative laboratory studies would be ordered for premenopausal women with no history of hysterectomy?
- A.
HCG
- B.
HBV
- C.
HIV
- D.
HDL
Correct Answer
A. HCGExplanation
HCG stands for Human Chorionic Gonadotropin, a hormone that is produced during pregnancy. It is used as a marker to detect pregnancy and to monitor the progress of a pregnancy. In this case, since the question is about premenopausal women with no history of hysterectomy, ordering an HCG test would be relevant to check for pregnancy status. The other options (HBV, HIV, HDL) are not specifically related to preoperative laboratory studies for premenopausal women without a hysterectomy.Rate this question:
