WGU D117: NURS 6810 Advanced Health
Assessment Prep with Detailed Rationales
Course Code: WGU D117 / NURS 6810
Course Name: Advanced Health Assessment
Topic: Advanced Physical Examination, Clinical Reasoning, and
Differential Diagnosis
Academic Year: 2026/2027
1. A 45-year-old female presents with progressive shortness of breath and a
persistent dry cough. During the physical examination, the advanced practice
nurse performs thoracic percussion and notes a dull, flat sound over the
right lower lung field, along with decreased tactile fremitus and absent
breath sounds in the same area. Which pulmonary pathology is most
consistent with these physical findings?
A. Pleural effusion
B. Lobar pneumonia
C. Acute pneumothorax
D. Chronic emphysema
CORRECT ANSWER: A. Pleural effusion
RATIONALE: A pleural effusion involves fluid accumulation within the
pleural space, which acts as a barrier that dampens sound and vibrations.
This fluid layer causes dullness to percussion, decreased tactile fremitus,
and decreased or absent breath sounds because it separates the lung tissue
from the chest wall.
• Distractor B is incorrect because lobar pneumonia causes consolidation,
which increases tactile fremitus and produces bronchial breath sounds rather
than absent sounds.
• Distractor C is incorrect because a pneumothorax fills the space with air,
resulting in hyperresonance to percussion, not dullness.
• Distractor D is incorrect because emphysema features chronic alveolar
hyperinflation, which causes generalized hyperresonance and a decreased
diaphragmatic excursion bilaterally.
,2. During a comprehensive neurological examination of a 68-year-old patient
who recently suffered a cerebrovascular accident, the nurse practitioner
stabilizes the patient's foot and sharply dorsiflexes the ankle, maintaining the
position. The foot responds with a rhythmic, oscillating series of
movements. What is the correct term for this finding, and what does it
indicate?
A. Ankle clonus; upper motor neuron lesion
B. Positive Babinski sign; lower motor neuron deficit
C. Hoffmann's sign; cerebellar tract degeneration
D. Asterixis; metabolic hepatic encephalopathy
CORRECT ANSWER: A. Ankle clonus; upper motor neuron lesion
RATIONALE: Ankle clonus is a hyperactive, rhythmic reflex response
elicited by sudden, sustained stretch of the muscle. Its presence is a classic
sign of hyperreflexia, which points directly to an upper motor neuron
lesion within the central nervous system.
• Distractor B is incorrect because a Babinski sign is evaluated by stroking the
lateral plantar surface of the foot to check for great toe extension, not by
stretching the Achilles tendon.
• Distractor C is incorrect because Hoffmann's sign evaluates upper extremity
hyperreflexia by flicking the nail of the middle finger.
• Distractor D is incorrect because asterixis is a flapping tremor of the hands
observed during wrist extension, typically caused by metabolic toxins like
ammonia.
3. A 22-year-old college student presents to the clinic complaining of severe,
localized right lower quadrant abdominal pain that began periumbilically. To
evaluate for suspected acute appendicitis, the clinician deeply palpates the
patient's left lower quadrant and asks if pain is felt anywhere else. The
patient reports sharp pain in the right lower quadrant. Which clinical sign is
this?
,A. Rovsing's sign
B. McBurney's sign
C. Psoas sign
D. Murphy's sign
CORRECT ANSWER: A. Rovsing's sign
RATIONALE: Rovsing's sign is positive when deep palpation of the left
lower quadrant elicits pain in the right lower quadrant. This occurs because
pressing on the left side shifts the abdominal contents and perturbs the
inflamed peritoneum overlying the appendix on the right side.
• Distractor B is incorrect because McBurney's sign refers to localized
tenderness felt directly upon palpating McBurney's point itself, not indirect
pain from the left side.
• Distractor C is incorrect because the psoas sign is elicited by extending the
right hip, which causes pain due to friction against an inflamed psoas
muscle.
• Distractor D is incorrect because Murphy's sign is used to assess for acute
cholecystitis by checking for pain and inspiratory arrest during right upper
quadrant palpation.
4. True or False: When performing an ophthalmoscopic examination, a loss of
the normal red reflex and the appearance of a cloudy or opaque lens
indicates the advanced development of macular degeneration.
A. True
B. False
CORRECT ANSWER: B. False
RATIONALE: A cloudy, opaque lens combined with a diminished or absent
red reflex indicates a cataract. In contrast, macular degeneration affects
the central retina (macula) and presents with changes in central vision and
drusen deposits during a fundoscopic examination, leaving the lens structure
clear.
, • Distractor A is incorrect because macular degeneration does not alter the
physical clarity of the lens capsule or obscure the red reflex in this manner.
5. A 58-year-old male with a history of long-standing hypertension presents for
a routine physical exam. Auscultation at the cardiac apex reveals a low-
pitched, late diastolic sound occurring just before the first heart sound (S1).
How should the clinician document this sound, and what does it structurally
represent?
A. Fourth heart sound (S4); ventricular filling against a stiff, noncompliant
ventricle
B. Third heart sound (S3); rapid passive ventricular filling into an
overloaded chamber
C. Opening snap; stenotic degeneration of the aortic valve leaflets
D. Ejection click; normal physiological closure of the ductus arteriosus
CORRECT ANSWER: A. Fourth heart sound (S4); ventricular filling
against a stiff, noncompliant ventricle
RATIONALE: A late diastolic sound occurring right before S1 is a fourth
heart sound (S4), or an atrial gallop. It is produced when the atria contract
to push blood into a stiff, noncompliant ventricle, which is a common
structural consequence of ventricular hypertrophy secondary to long-
standing hypertension.
• Distractor B is incorrect because an S3 occurs early in diastole during rapid
passive filling and is associated with volume overload or heart failure.
• Distractor C is incorrect because an opening snap is a sharp, high-pitched
early diastolic sound associated with mitral stenosis, not aortic degeneration.
• Distractor D is incorrect because an ejection click occurs early in systole
right after S1, marking the opening of diseased semilunar valves.
6. The nurse practitioner is performing a cranial nerve assessment on a patient
who sustained facial trauma. When the patient is asked to smile, frown, puff
out their cheeks, and tightly close their eyes, the nurse practitioner notes
