NU650 | NU650 Health Assessment / Nursing Exam
3 Version 3 | Questions with Correct Answers and
Expert Explanation for Each Question | Regis
1. When assessing the function of Cranial Nerve II, which of the following tools should
the nurse use?
A. A Snellen chart
B. A penlight
C. A tuning fork
D. An otoscope
Correct Answer: A
Expert Explanation: Cranial nerve II is the optic nerve, which is responsible for
visual acuity and visual fields. Using a Snellen chart allows the clinician to measure
distance vision accurately at 20 feet. This assessment is essential for detecting
vision loss or refractive errors during a comprehensive physical exam.
2. A patient is unable to differentiate between a key and a coin placed in their hand
with their eyes closed. Which term describes this finding?
A. Astereognosis
B. Agraphesthesia
C. Ataxia
,D. Anosmia
Correct Answer: A
Expert Explanation: Stereognosis is the ability to recognize objects by feeling their
form, size, and weight while the eyes are closed. Astereognosis indicates a sensory
cortex lesion or a problem in the posterior column of the spinal cord. This finding
suggests the patient cannot integrate tactile sensations to identify a common object.
3. During a musculoskeletal exam, the nurse asks the patient to move their arm away
from the midline of the body. This movement is called:
A. Abduction
B. Flexion
C. Adduction
D. Extension
Correct Answer: A
Expert Explanation: Abduction is defined as moving a limb or body part away from
the median plane of the body. In contrast, adduction moves the limb toward the
midline. Correct identification of these movements is vital for documenting range of
motion in the shoulder or hip.
, 4. Which assessment technique is most appropriate for identifying a small amount of
fluid in the knee joint?
A. The Bulge sign
B. The McMurray test
C. The Lachman test
D. The Phalen test
Correct Answer: A
Expert Explanation: The bulge sign is used to detect small amounts of fluid,
typically 4 to 8 mL, in the suprapatellar pouch. The clinician milks the medial aspect
of the knee and then taps the lateral side to observe for a fluid wave. This differs
from ballottement, which is used for larger effusions.
5. When grading muscle strength, a nurse notes that the patient has full range of
motion against gravity but not against resistance. How should this be documented?
A. Grade 2/5
B. Grade 3/5
C. Grade 4/5
D. Grade 5/5
Correct Answer: B
