A nurse is preparing a client for a sigmoidoscopy. In which of the following positions should the nurse place the client?

Orthopneic

Trendelenburg

Prone

Knee-chest

Answer and Explanation

The Correct Answer is D

knee-chest. During sigmoidoscopy, the client should lie on their left side with their right knee flexed slightly. The nurse should then position the client in the knee-chest (Sims) position, where the client leans forward with bent knees and support the chest and forearms on the table or a pillow. This allows better visualization and access to the rectal area for the sigmoidoscopy procedure.

An explanation for incorrect choices:

A. Orthopneic position is upright sitting with arms and elbows resting on a table or on a pillow, which helps clients who have difficulty breathing; it is not suitable for sigmoidoscopy.

B. Trendelenburg position

is supine with the head lower than the feet, which can cause blood flow to the head and increased intracranial pressure; it is not suitable for sigmoidoscopy.

C. Prone position is lying face down, which is not suitable for sigmoidoscopy.

Correct Answer is D

Explanation

The client had a right radical mastectomy, which can lead to lymphedema, a buildup of fluid that can cause swelling in the arm. Using the client's left arm to obtain blood samples can help prevent injury to the affected arm and reduce the risk of lymphedema. Obtaining blood pressure readings with the client's left arm is also recommended. Range-of-motion exercises are important to prevent stiffness, and elevating the affected arm can help reduce swelling.

A: Obtaining blood pressure readings with the client's right arm can cause injury and increase the risk of lymphedema.

B: Limiting range-of-motion exercises can lead to stiffness and may not prevent lymphedema.

C: Keeping both arms below the level of the client's heart can help reduce swelling, but does not directly prevent lymphedema.

A. Metabolic acidosis B. Respiratory acidosis C. Respiratory alkalosis D. Metabolic alkalosis

Correct Answer is B

Explanation

This ABG result indicates that the client has an excess of carbon dioxide (CO2) due to hypoventilation.

A. "Metabolic acidosis" is an incorrect answer because the pH is low and the HCO3 is within normal range.

C. "Respiratory alkalosis" is an incorrect answer because the pH is low and the PaCO2 is elevated.

D. "Metabolic alkalosis" is an incorrect answer because the HCO3 is within normal range, and the pH is low.

Explanation: The ABG result shows a low pH, elevated PaCO2, and normal HCO3, indicating respiratory acidosis. This condition can be caused by conditions that affect breathing, such as pneumonia, asthma, or chronic obstructive pulmonary disease (COPD).
