Questions & Verified Answers
1. A patient presents with a ‘herald patch’ followed by a Christmas tree distribution of smaller
lesions. What is the most likely diagnosis?
A. Tinea Corporis
B. Atopic Dermatitis
C. Psoriasis
D. Pityriasis Rosea
Answer: D
Rationale: Pityriasis rosea typically begins with a single, large herald patch followed by smaller lesions in a
distribution that follows the lines of cleavage (Christmas tree pattern). This is an important clinical concept
because selecting the correct answer (D) requires understanding both the pathophysiology and the practical
nursing implications.
2. During a physical exam, a positive McMurray test suggests which of the following injuries?
A. ACL tear
B. MCL sprain
C. Meniscal tear
D. Patellar tendonitis
Answer: C
Rationale: The McMurray test involves rotation of the knee and is used to identify tears in the meniscus. This is
an important clinical concept because selecting the correct answer (C) requires understanding both the
pathophysiology and the practical nursing implications. Recognizing this principle allows the nurse to prioritize
care, anticipate complications, and provide accurate patient education.
3. Which physical exam maneuver is most sensitive for detecting an Anterior Cruciate Ligament
(ACL) tear?
A. Lachman test
B. Anterior Drawer test
C. Posterior Drawer test
D. Valgus stress test
Answer: A
Rationale: The Lachman test is considered more sensitive and reliable than the Anterior Drawer test for
diagnosing ACL deficiency. Applying this knowledge in clinical settings supports safe, evidence-based practice
and improves patient outcomes. This is an important clinical concept because selecting the correct answer (A)
requires understanding both the pathophysiology and the practical nursing implications.

4. A patient complains of severe eye pain, blurred vision, and seeing halos around lights. On
exam, the pupil is fixed and mid-dilated. What is the priority differential?
A. Cataract
B. Macular degeneration
C. Acute angle-closure glaucoma
D. Conjunctivitis
Answer: C
Rationale: Acute angle-closure glaucoma is an ocular emergency characterized by sudden pain, halos, and a
mid-dilated pupil. Applying this knowledge in clinical settings supports safe, evidence-based practice and
improves patient outcomes. This is an important clinical concept because selecting the correct answer (C)
requires understanding both the pathophysiology and the practical nursing implications.
5. In the differential diagnosis of pharyngitis, which criteria are used to determine the likelihood
of Group A Beta-Hemolytic Streptococcus (GABHS)?
A. FRAMES criteria
B. Centor criteria
C. CURB-65
D. LIGHTS criteria
Answer: B
Rationale: The Centor criteria (fever, tonsillar exudate, tender anterior cervical lymphadenopathy, and absence
of cough) help estimate the probability of Strep pharyngitis. Recognizing this principle allows the nurse to
prioritize care, anticipate complications, and provide accurate patient education.
6. A 24-year-old female presents with a pruritic rash in the finger webs and wrist creases that is
worse at night. What is the most likely diagnosis?
A. Scabies
B. Contact dermatitis
C. Dyshidrotic eczema
D. Tinea manuum
Answer: A
Rationale: Scabies commonly presents with intense nocturnal pruritus and burrows in the interdigital spaces
and flexor surfaces of the wrists. This is an important clinical concept because selecting the correct answer (A)
requires understanding both the pathophysiology and the practical nursing implications. Recognizing this
principle allows the nurse to prioritize care, anticipate complications, and provide accurate patient education.
