Answer and Explanation

The Correct Answer is D

B. Arthroscopy: Arthroscopy is a procedure that involves inserting a camera into the joint to visualize the interior but is not specifically for fluid aspiration.

C. Magnetic resonance imaging (MRI): MRI provides detailed images of soft tissues, joints, and bones but is not a direct method for aspirating synovial fluid.

Correct Answer is D

Explanation

A. Pallor of the affected extremity: Pallor usually indicates vascular issues rather than a rotator cuff injury.

B. Alteration in the appearance of the shoulder joint: Visible deformity may suggest a dislocation or fracture, not specifically a rotator cuff injury.

C. Numbness of the thumb and index finger: Numbness of the thumb and index finger is more likely related to nerve compression, such as carpal tunnel syndrome.

D. Increased pain with lifting the arm: This is characteristic of a rotator cuff injury, which typically causes pain and weakness with shoulder movements, especially lifting the arm.

A. Provide an elevated toilet seat. B. Assist of bed immediately following surgery. C. Medicate with pain medications. D. Maintain weight bearing as prescribed.

Correct Answer is D

Explanation

A. Provide an elevated toilet seat: This is important for preventing hip dislocation but is not the immediate priority.
B. Assist out of bed immediately following surgery: Mobilizing the patient is important to prevent complications such as deep vein thrombosis (DVT) and pneumonia, but this should be done safely and as prescribed.
C. Medicate with pain medications: Pain management is crucial for postoperative recovery but is part of comprehensive care rather than the single priority.
D. Maintain weight bearing as prescribed: Following weight-bearing restrictions is critical to ensure proper healing and prevent complications such as dislocation or prosthetic failure. This is the immediate priority in terms of preventing harm and ensuring recovery.
