NR 511 Week 5 Quiz
Question 1
pts
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
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
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.
