NEW QUESTION # 26
An 83-year-old female with a medical history of congestive heart failure, critical aortic stenosis, end-stage renal disease, and morbid obesity presents to the office with a complaint of right knee pain for two years. The pain is worse with activity and better with rest. She notes no redness, warmth, or swelling in the joint, with no other joints being painful. A physical examination reveals crepitus in the right knee with medial and lateral joint line tenderness of the left knee. X-rays of the right knee from six months ago are consistent with severe tricompartmental osteoarthritis. Due to morbid obesity, visualization of bony landmarks is not possible and the decision is made to proceed with an ultrasound-guided knee injection with a hyaluronic acid derivative.
Prior to injection, where should the needle tip be visualized?
- A. C
- B. D
- C. B
- D. A
Answer: C

NEW QUESTION # 30
What should be taken into consideration prior to any procedure?
- A. A slight to-and-fro movement or injection of a small amount of lidocaine may be beneficial in visualizing the needle.
- B. The shortest pathway to the region of interest should be selected with consideration given to adjacent neurovascular structures.
- C. The transducer should be aligned perpendicular to the plane of the needle.
- D. The needle should be visualized only prior to its insertion to the target area.
Answer: B
