Bone biopsy

Arthroscopy

Magnetic resonance imaging (MRI)

Arthrocentesis

Answer and Explanation

The Correct Answer is D

A. Bone biopsy: A bone biopsy involves taking a sample of bone tissue, which is not relevant for diagnosing septic arthritis.

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.

D. Arthrocentesis: Arthrocentesis is the procedure of aspirating synovial fluid from the joint space, which is essential for diagnosing septic arthritis.

Correct Answer is B

Explanation

A. "This will help to decrease the frequency of dressing changes." The placement of a prosthesis does not impact the frequency of dressing changes, which are based on wound care needs.

B. "This will improve your ability to ambulate sooner." Early prosthesis placement can aid in quicker rehabilitation and earlier ambulation.

C. "This will decrease the chance of you experiencing phantom limb pain." Prosthesis placement does not necessarily decrease the occurrence of phantom limb pain, which is a common phenomenon after amputation.

D. "Placing this now will improve the fit of the prosthesis." The fit of the prosthesis is more related to the residual limb's healing and shaping, not necessarily the timing of initial placement.

A. Providing a caring and supportive attitude during a challenging time B. Monitoring pin and wound sites for signs of infection C. Being aware that the patient may experience issues with body image D. Helping the patient achieve a desired level of mobility

Correct Answer is B

Explanation

A. Providing a caring and supportive attitude during a challenging time: While emotional support is crucial and beneficial for the patient's overall well-being and recovery, it is not the primary focus when dealing with external fixation and the risk of complications.

B. Monitoring pin and wound sites for signs of infection: Infection is a significant risk with external fixation devices, and early detection is critical to prevent severe complications such as osteomyelitis. This makes monitoring for infection the most important focus.

C. Being aware that the patient may experience issues with body image: Body image concerns are valid and can affect a patient’s mental health, but they are secondary to the physical risks associated with external fixation, such as infection.

D. Helping the patient achieve a desired level of mobility: Mobility is an important goal in the patient's rehabilitation, but ensuring the prevention of infection takes precedence because an infection can severely impact overall recovery.
