Introduction
The Module 3 NURS 5433 exam assesses advanced family nurse practitioner knowledge required for
clinical management of complex patient presentations. This examination evaluates pediatric infectious
diseases, Kawasaki disease, vector-borne illnesses, bacterial infections, family systems theory,
anticoagulation management, and renal pathophysiology. Questions are structured in multiple-choice
and scenario-based formats emphasizing real-world application, critical thinking, differential diagnosis,
and evidence-based decision-making. Candidates must demonstrate competency in recognizing clinical
presentations, selecting appropriate diagnostics, and developing comprehensive treatment plans for
diverse patient populations.
SECTION ONE: QUESTIONS 1–100
Question 1
A 4-year-old child presents with a "slapped cheek" appearance and a lace-like rash on the trunk. The
mother reports the child had a low-grade fever and runny nose about a week ago. What is the most
likely diagnosis?
A. Rubella
B. Fifth disease
C. Measles
D. Scarlet fever
B. Fifth disease
, RATIONALE: Fifth disease (erythema infectiosum), caused by Human Parvovirus B19, presents with a
characteristic "slapped cheek" rash followed by a lace-like maculopapular rash on the trunk. The
prodromal symptoms of fever and coryza occur about 1 week before the rash appears .
Question 2
A child is diagnosed with fifth disease. The parent asks when the child can return to school. What is the
nurse practitioner's best response?
A. "The child is contagious until the rash disappears."
B. "The child is no longer contagious once the rash appears and may return to school."
C. "The child must remain home for 7 days after the rash appears."
D. "The child needs a negative parvovirus B19 assay before returning."
B. "The child is no longer contagious once the rash appears and may return to school."
RATIONALE: In fifth disease, the patient is no longer contagious when the rash appears. Children
may attend school once the rash is present. This is a key teaching point for parents .
Question 3
A 4-year-old child presents with fever for more than 5 days, bilateral non-exudative conjunctivitis,
strawberry tongue, cracked lips, and swollen hands and feet. What is the most likely diagnosis?
A. Scarlet fever
B. Kawasaki disease
C. Measles
D. Stevens-Johnson syndrome
B. Kawasaki disease
RATIONALE: Kawasaki disease is characterized by fever lasting more than 5 days plus at least 4 of 5
diagnostic criteria: bilateral conjunctivitis without exudate, red tongue/oral cavity changes,
lymphadenopathy, extremity changes, and polymorphous rash. This presentation meets the criteria .
Question 4
A child with Kawasaki disease is at highest risk for which complication?
A. Renal failure
B. Cardiac complications including coronary artery aneurysms
C. Hepatic failure
D. Pulmonary fibrosis
B. Cardiac complications including coronary artery aneurysms
RATIONALE: The most serious complication of Kawasaki disease is cardiac involvement, including
coronary artery aneurysms, myocarditis, and risk of myocardial infarction. Patients require urgent
cardiology referral and echocardiography .
Question 5
, A 43-year-old man presents with an expanding circular rash on his left lower leg with central clearing,
fever, and myalgia. He recently returned from camping in Minnesota. What is the most likely diagnosis?
A. Cellulitis
B. Lyme disease
C. Rocky Mountain spotted fever
D. MRSA
B. Lyme disease
RATIONALE: Lyme disease, caused by Borrelia burgdorferi transmitted by Ixodes ticks, presents with
erythema migrans (expanding circular rash with central clearing), fever, and myalgia. The history of
camping in an endemic area is consistent .
Question 6
A patient presents with a painful, erythematous lesion with a 3 cm pustule and surrounding erythema
on the left arm. What is the most appropriate initial management?
A. Oral antibiotics only
B. Incision and drainage with wound culture
C. Topical antibiotic ointment
D. Immediate IV vancomycin
B. Incision and drainage with wound culture
RATIONALE: For abscesses less than 5 cm, incision and drainage is the primary treatment. Antibiotics
are not routinely needed for small abscesses unless there is significant surrounding cellulitis or systemic
symptoms. Wound culture should be obtained during I&D .
Question 7
A patient presents with unilateral lower extremity swelling, redness, warmth, and fever. There are no
areas of broken skin. What is the most likely diagnosis?
A. Deep vein thrombosis
B. Cellulitis
C. Lymphedema
D. Gout
B. Cellulitis
RATIONALE: Cellulitis presents with erythema, warmth, swelling, and pain without well-defined
borders. Fever and malaise may be present. Treatment includes elevation, immobilization, and
antibiotics such as cephalexin or dicloxacillin .
Question 8
What diagnostics are needed to confirm fifth disease?
