A nurse is preparing a client for a sigmoidoscopy. In which of the following positions should the nurse place the client?
A.
Orthopneic
B.
Trendelenburg
C.
Prone
D.
Knee-chest
The Correct answer and Explanation is:
The correct answer is D. Knee-chest.
Explanation:
A sigmoidoscopy is a medical procedure used to examine the lower part of the large intestine (the sigmoid colon and rectum). This procedure allows the physician to check for abnormalities such as polyps, tumors, inflammation, or bleeding. The choice of patient positioning during a sigmoidoscopy is crucial for both the ease of the procedure and the comfort of the patient.
Knee-Chest Position: The knee-chest position involves the client kneeling on the examination table, with their chest and face down, resting on the table, and their hips raised. This position is specifically used for sigmoidoscopy because it provides the best access to the sigmoid colon by allowing the rectum and lower colon to straighten. This facilitates easier insertion of the sigmoidoscope and enhances the physician’s ability to visualize the interior of the colon.
Incorrect Options:
- A. Orthopneic Position: The orthopneic position involves the client sitting up and leaning slightly forward, usually with arms supported on a pillow or overbed table. This position is typically used to facilitate easier breathing for clients with respiratory conditions, not for lower gastrointestinal procedures.
- B. Trendelenburg Position: The Trendelenburg position involves placing the client flat on their back with the head of the bed lowered and the feet elevated. This position is often used in situations requiring increased blood flow to the brain, such as in cases of hypotension, but is not appropriate for a sigmoidoscopy.
- C. Prone Position: The prone position involves the client lying flat on their stomach. While this position may be used for some back procedures, it does not provide the necessary access for a sigmoidoscopy.
In summary, the knee-chest position is the preferred choice for a sigmoidoscopy because it provides optimal anatomical access for the procedure, ensuring both safety and effectiveness.
