A nurse at a long-term care facility is assessing a client who just received hearing aids. Which of the following actions should indicate to the nurse that the client understands how to use the hearing aids? (Select all that apply.)

A. Positive Skin Hypersensitivity Test: This is incorrect as it typically involves pain or discomfort with light touch, unrelated to rebound tenderness.

B. Positive Rovsing Sign: A positive Rovsing sign occurs when pain is felt in the right lower quadrant upon palpation of the left lower quadrant, indicating possible appendicitis.

C. Psoas Sign: This is elicited by extending the hip, and a positive sign indicates irritation of the iliopsoas muscle, often seen in appendicitis.

D. Positive Obturator Sign: This involves internal rotation of the hip, also used in appendicitis assessments but involves different positioning.

A. Abdominal x-ray: While it can show gas or bowel obstructions, it is less effective for confirming fluid presence.

B. Shifting dullness: This physical exam technique can indicate fluid but is less accurate than ultrasound.

C. Fluid wave: This physical exam can help suggest the presence of fluid, but it is also less reliable than imaging studies.

D. Ultrasound: An ultrasound is the most accurate and non-invasive way to confirm the presence of fluid, such as ascites, in the abdomen. It provides detailed imaging and confirmation without invasive procedures.
