NR 511 Differential Diagnosis And Primary Care Practicum Week_5_quiz

A 48-year-old male presents with acute low back pain in the right that increases when standing and bending. Upon physical exam, lower extremity muscle strength is 5/5 and straigh leg raise test is negative. Which of the following is the most likely diagnosis? You Answered Spondylolisthesis. Osteoarthritis. Correct Answer Muscle strain. Herniated nucleus pulposus. Muscle strain is usually located in the low back and is unilateral in location. The onset is acute, and pain increases with standing and bending and decreases with sitting. The straight leg raise test and plain x-ray are both negative. Question 2 1 / 1 pts A 55-year-old patient is able to complete range of motion (ROM) against gravity with some resistance. The nurse practitioner would assign which of the following numerical grades to this manual muscle testing description? Correct!4 3 2 5 Normal muscle strength and function and complete ROM against gravity with full or normal resistance would be given a numerical grade of 5. Complete ROM against gravity with some resistance is given a numerical grade of 4 and described as good muscle strength. Complete ROM against gravity is indicative of fair muscle strength and function and is given a numerical grade of 3. A grade of 2, denoting poor muscle strength, is given for complete ROM with gravity eliminated. Question 3 1 / 1 pts The valgus stress test, varus stress test, Lachman test, and thumb sign are all considered standard tests to check the integrity of the ligaments of the knee. Which of the following would the clinician choose to assess the anterior cruciate ligament (ACL), which is the most commonly involved structure in severe knee injury? Thumb sign. Correct! Lachman test. Valgus stress test. Varus stress test.The Lachman test assesses the ACL. Question 4 0 / 1 pts A 55-year-old female presents to the clinic with complaints of left hand and wrist pain and swelling after a slip and fall on the ice yesterday. On examination, the clinician notes tenderness at the “anatomical snuffbox.” This finding most likely indicates which of the following? Hamate fracture. You Answered Radial head fracture. Ulnar styloid fracture. Correct Answer Scaphoid fracture. There is tenderness over the “anatomical snuffbox” in a scaphoid (aka navicular) fracture, the most common injury of the carpal bones. Poor blood supply puts the scaphoid bone at risk of avascular necrosis; therefore, wrist pain and tenderness in the anatomical snuffbox, even without history of antecedent trauma, warrant a wrist x-ray. Question 5 1 / 1 pts A 16-year-old male patient presents to the clinic after sustaining a football injury to his right knee. The clinician elicits a positive anterior/posterior drawer sign. This test indicates an injury to the ______? Collateral ligament. Lateral meniscunosis Primary Care Practicum Week_5_quiz
