Final answer:
For a modified radical mastectomy, extra #10 blades must be readily available due to their common use for the larger incisions required in such procedures.
The correct answer is D.
Step-by-step explanation:
The student asks which instruments must be readily available for a modified radical mastectomy. extra #10 blades. Modified radical mastectomy is a surgical procedure often used in the treatment of breast cancer. During the procedure, a surgical blade is used to make incisions and remove tissue. The 10 blade is typically used for making larger incisions, which is common in mastectomy procedures. Thus, extra 10 blades should be readily available to ensure that the surgery can proceed smoothly without unnecessary interruptions for a blade change.
This surgical procedure involves making significant incisions for tissue removal. The #10 blade, designed for larger incisions, ensures efficiency during the surgery. Having an ample supply of these blades is essential to prevent interruptions, enabling a smooth and uninterrupted procedure for optimal patient care.
