NSG 548 Exam 3 V3 | NSG 548 FNP Role:
Children & Families | Actual Q&A with
Rationale (NSG548 Exam 3) | Wilkes
University
1. A 10-year-old male presents with sudden onset of scrotal pain and a ‘blue dot sign’ on the
upper pole of the testis. What is the most likely diagnosis?
A. Testicular Torsion
B. Hydrocele
C. Epididymitis
D. Torsion of the Appendix Testis
Answer: D
Rationale: The ‘blue dot sign’ is a pathognomonic finding for torsion of the testicular
appendage. Unlike testicular torsion, the pain is often localized and the cremasteric reflex is
typically preserved. Management is usually conservative with rest and NSAIDs as the
appendage will eventually undergo necrosis and be reabsorbed.
2. Which of the following is considered the gold standard for diagnosing Cystic Fibrosis in a
pediatric patient?
A. Chest X-ray
B. Sputum culture
,C. Genetic testing for CFTR mutation
D. Sweat Chloride Test
Answer: D
Rationale: The sweat chloride test remains the primary diagnostic tool for Cystic Fibrosis.
A chloride concentration greater than 60 mmol/L on two separate occasions is diagnostic.
While genetic testing can identify specific mutations, the physiological sweat test confirms
the functional defect.
3. A 4-year-old is brought in for a well-child visit. According to the CDC, which immunization
should the child receive today?
A. DTaP, IPV, MMR, and Varicella
B. Hib, PCV13, and Rotavirus
C. Tdap, MCV4, and HPV
D. Hepatitis B and Meningococcal B
Answer: A
Rationale: Children aged 4 to 6 years require booster doses of DTaP, IPV, MMR, and
Varicella before entering kindergarten. These vaccines ensure immunity levels are high
before the child enters a school environment. Providers must review the immunization
registry to ensure no previous doses were missed.
, 4. What is the primary pharmacological treatment for a child diagnosed with mild persistent
asthma?
A. Short-acting beta-agonist (SABA) PRN only
B. Low-dose Inhaled Corticosteroid (ICS)
C. Long-acting beta-agonist (LABA) monotherapy
D. Oral Prednisone for 5 days
Answer: B
Rationale: For mild persistent asthma, the NAEPP guidelines recommend a daily low-dose
inhaled corticosteroid as the preferred controller medication. This helps reduce airway
inflammation and prevents the frequency of rescue inhaler use. Patients should also have a
SABA available for acute exacerbations.
5. In a child with suspected Attention Deficit Hyperactivity Disorder (ADHD), how many
settings must the symptoms be present in for a DSM-5 diagnosis?
A. At least two settings
B. One setting only
C. At least three settings
D. Only in the school setting
Answer: A
