Why Wound Dressing & Drains matters

Wound Dressing & Drains is tested because wound assessment and management skills are used across all clinical settings.

Sample Practice Questions (5)

1. Which type of drain operates by creating a closed-suction vacuum and is commonly used after mastectomy or abdominal surgery to prevent seroma formation?

  • Penrose drain
  • Jackson-Pratt (JP) drain
  • Cigarette drain
  • T-tube drain

2. A patient has undergone an open reduction and internal fixation of a tibial fracture (Class I clean wound). The surgeon asks the surgical technologist to prepare the dressing. The MOST appropriate initial dressing for this type of wound is:

  • Wet-to-dry gauze dressing changed every 4 hours
  • Non-adherent contact layer (Adaptic or Xeroform), followed by absorbent gauze, and secured with an elastic bandage or tape
  • Transparent film dressing (Tegaderm) alone over the full incision
  • No dressing — clean surgical wounds heal better when left open to air

3. A Jackson-Pratt (JP) drain has been placed at a surgical site. In the immediate postoperative period, the circulating nurse reports that the drain has produced 200 mL of bright red output in the first hour. This finding suggests:

  • Normal postoperative drainage that requires no intervention
  • Possible active hemorrhage requiring immediate notification of the surgeon
  • The drain is malfunctioning and should be replaced
  • The drain reservoir needs to be emptied but no further action is needed

4. When applying a postoperative dressing, the surgical technologist should apply the dressing:

  • Before the final count is completed to protect the wound
  • After the final count is verified as correct, the wound is cleaned of prep solution and blood, and the surgeon approves dressing application
  • After the patient is extubated and awake
  • Only after the patient is transferred to the stretcher

5. An occlusive dressing such as a transparent film (Tegaderm) is MOST appropriate for which type of wound?

  • A large, heavily draining abdominal wound
  • A clean, minimally draining surgical incision or IV catheter site
  • A deep wound requiring packing with gauze
  • A full-thickness burn with eschar
