Identify the following denoted instrument.

Appeared in: NORCET 2 - 2021 (shift-1)

Explanation

The instrument in the image is a Deaver retractor, identified by its distinct, gentle C-shaped curve.
It features a broad, flat blade with a smooth, rounded tip designed to retract large organs without causing injury.
Its primary function is to provide exposure in deep surgical fields, such as the abdominal or thoracic cavities, by holding back organs like the liver, stomach, or bladder.

Option B: A Doyen retractor has a blade that is set at a right angle to the handle, which is a different shape from the gentle C-curve of the instrument shown.
Option C: Morris forceps are grasping instruments. While there is a Morris retractor, it is a heavy, right-angled instrument, which does not match the smooth, curved shape of the Deaver retractor.
Option D: Allis forceps are not retractors; they are grasping instruments with interlocking sharp teeth used to hold or grasp heavy tissue that is being removed.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of surgical instruments as background academic context rather than a clinical decision trigger.
Proper identification and use of retractors are critical for patient safety. Using the wrong retractor can lead to inadequate exposure or tissue damage.
When using deep retractors like the Deaver, nurses should ensure that moist laparotomy pads are placed between the retractor blade and the organ to cushion the tissue and prevent injury.
Prolonged or forceful retraction can cause tissue ischemia or nerve damage. The surgical team must communicate to ensure traction is gentle and periodically released if possible.

How to Approach the Question

First, carefully examine the image of the instrument, paying close attention to its overall shape, the design of the blade, and the handle.
Note the key features: a long handle and a broad, flat blade with a continuous, gentle 'C' or 'question mark' curve.
Recall the characteristics of the instruments listed in the options. Think about the difference between a retractor (holds tissue back) and forceps (grasps tissue).
Eliminate the forceps (Morris, Allis) as they are grasping tools and do not match the shape.
Compare the shape to known retractors. The C-shape is characteristic of a Deaver, whereas a Doyen has a right-angled blade.
Select the option that best matches the visual evidence.
