Question 1

Which of the following is the CORRECT sequence for wound irrigation using a syringe?

Accepted Answer

Irrigate with normal saline using a 30–60 mL syringe with an 18–19 gauge angiocath, directed at the wound surface

Answer

Evidence-based wound irrigation uses normal saline or potable water delivered with sufficient pressure (4–15 psi) via a large syringe and angiocath. Hydrogen peroxide and povidone-iodine are cytotoxic to healing tissue and are not recommended.

Question 2

A community paramedic observes a sacral wound with undermining noted at the 3 o'clock and 9 o'clock positions. What does 'undermining' mean in wound assessment?

Accepted Answer

Tissue destruction extending beyond the wound edges under intact skin

Answer

Undermining refers to tissue destruction that extends under the intact skin surrounding the wound edges, creating a pocket or cave-like space. It is documented by clock position and depth measured with a cotton-tipped applicator.

Question 3

Which dressing type is MOST appropriate for a heavily exudating wound with necrotic tissue?

Accepted Answer

Calcium alginate dressing

Answer

Calcium alginate dressings are highly absorbent and appropriate for moderately to heavily exudating wounds. They also support autolytic debridement by maintaining a moist wound environment favorable for enzymatic breakdown of necrotic tissue.

Question 4

The Braden Scale for predicting pressure injury risk scores patients on six subscales. A total Braden Score of 12 indicates:

Accepted Answer

High risk for pressure injury development

Answer

Braden Scale risk categories: 15–23 = low risk, 13–14 = mild risk, 10–12 = moderate risk, ≤9 = severe risk. A score of 12 indicates high risk (moderate per some classifications), warranting intensive preventive interventions.

Question 5

Which intervention is the CORNERSTONE of pressure injury prevention in a bedridden patient during home visits?

Accepted Answer

Regular repositioning (every 2 hours) and pressure redistribution surfaces

Answer

Regular repositioning (at minimum every 2 hours) combined with pressure redistribution mattresses/overlays is the evidence-based cornerstone of pressure injury prevention, reducing sustained pressure on bony prominences.
