LPN Fundamentals of Nursing

Correct Answer: B

Rationale: When using a cane, it is crucial to move the cane forward first to provide support and enhance balance. Advancing the cane before the weaker or stronger leg helps widen the base of support, thereby improving stability during ambulation. Keeping the cane too far or too close to the body can affect its supportive function. Moreover, utilizing the cane solely for stair climbing limits its overall utility in maintaining balance and stability during regular walking.

Correct Answer: D

Rationale: Ensuring the water seal chamber is filled to the prescribed level is essential for the chest tube's effective functioning. This maintains the integrity of the system, prevents air from entering the pleural space, and facilitates proper drainage. Stripping the drainage tubing, keeping the drainage system below the chest level, or clamping the chest tube during ambulation are not recommended practices and can lead to complications.

Correct Answer: C

Rationale: The correct answer is C. Cleaning around the stoma with mild soap and water is crucial for colostomy care as it helps prevent infection and skin irritation. Changing the colostomy bag frequency, dietary modifications, or applying lotion are not primary aspects of stoma care. Proper cleaning around the stoma helps maintain hygiene and prevents complications, making it a key component of caring for a colostomy.

Correct Answer: A

Rationale: Placing a pillow between the client's legs is crucial post hip arthroplasty surgery to prevent hip dislocation. This intervention helps maintain proper alignment and prevents legs from crossing midline, reducing the risk of hip prosthesis dislocation. Elevating the head of the bed to 45 degrees, positioning the client on the operative side, or keeping the client's legs adducted are not recommended postoperative interventions for a total hip arthroplasty, as they can increase the risk of complications and compromise the surgical site.

Correct Answer: D

Rationale: Having a second nurse witness the disposal of any unused portion of a controlled substance is a legal requirement to ensure proper disposal, prevent diversion, and maintain accountability. This practice helps in reducing the risk of misuse or unauthorized access to controlled substances, enhancing patient safety, and complying with legal regulations and standards.
