Scrub nurse: preparation of supplies and equipment on the sterile
Scrub nurse: preparation of supplies and equipment on the sterile ( 5 Questions)
Placing a grounding pad on the patient's skin near the surgical site is the correct action to prevent burns to the patient during electrocautery. The grounding pad provides a low-current-density pathway for the high-frequency cautery current to return to the electrosurgical unit, thus avoiding injury to other body areas.
Applying petroleum jelly to the patient's skin around the surgical site is not a correct action to prevent burns to the patient during electrocautery. Petroleum jelly is flammable and can ignite during electrocautery, causing fire and thermal injury to the patient.
Covering the patient's hair with a wet towel is not a correct action to prevent burns to the patient during electrocautery. A wet towel can create a conductive pathway for the cautery current to flow through, resulting in burns or shocks to the patient or the staff.
Removing any metal jewelry from the patient is a correct action to prevent burns to the patient during electrocautery, but it is not sufficient by itself. Metal jewelry can cause electrical arcing or heating, leading to skin burns or fire hazards. However, removing metal jewelry alone does not ensure a safe return pathway for the cautery current, which requires a grounding pad as well.
Choice A reason:
Placing a grounding pad on the patient's skin near the surgical site is the correct action to prevent burns to the patient during electrocautery. The grounding pad provides a low-current-density pathway for the high-frequency cautery current to return to the electrosurgical unit, thus avoiding injury to other body areas.
Choice B reason:
Applying petroleum jelly to the patient's skin around the surgical site is not a correct action to prevent burns to the patient during electrocautery. Petroleum jelly is flammable and can ignite during electrocautery, causing fire and thermal injury to the patient.
Choice C reason:
Covering the patient's hair with a wet towel is not a correct action to prevent burns to the patient during electrocautery. A wet towel can create a conductive pathway for the cautery current to flow through, resulting in burns or shocks to the patient or the staff.
Choice D reason:
Removing any metal jewelry from the patient is a correct action to prevent burns to the patient during electrocautery, but it is not sufficient by itself. Metal jewelry can cause electrical arcing or heating, leading to skin burns or fire hazards. However, removing metal jewelry alone does not ensure a safe return pathway for the cautery current, which requires a grounding pad as well.
