Pediatric Urology & Post-Operative Care: Hypospadias Repair Mastery
(200 Questions with Detailed Rationales)
MODULE 1: POST-OPERATIVE DISCHARGE INSTRUCTIONS
& MATERNAL GUIDANCE
Q1. A nurse is reviewing discharge instructions with the mother of a
toddler who had a surgical repair of a hypospadias (1). Which of the
following instructions should the nurse emphasize as the absolute
priority?
A. 'Administer warm sitz baths three times daily starting on
postoperative day one to soothe the surgical site.'
B. 'Ensure the child wears double diapers to protect the urinary stent
and surgical repair site from trauma.'
C. 'Encourage the toddler to resume straddle toys and tricycle riding
within 48 hours to prevent joint stiffness.'
D. 'Apply antibiotic ointment directly to the meatus twice daily using
sterile cotton-tipped applicators indefinitely.'
Correct Answer: B
Clinical Rationale: Double diapering is a standard post-operative
instruction following hypospadias repair when a urinary stent or
drainage catheter is in place. The inner diaper collects stool and
keeps it away from the surgical area, while the outer diaper holds the
urinary stent or catheter securely in place, preventing accidental
dislodgement or tension. Sitz baths are typically restricted until
dressings or stents are removed to avoid soaking incisions and
introducing pathogens. Straddle toys are strictly contraindicated for
2 to 4 weeks to prevent mechanical trauma and suture disruption.
, Ointment is applied as prescribed, but specific petroleum jelly
techniques are used without sterile cotton applicators unless
specifically directed.
Q2. The nurse is discussing post-operative medication management with
the mother of a toddler recovering from distal hypospadias repair (2).
The surgeon has prescribed oral oxybutynin. Which maternal statement
indicates a correct understanding of this medication's purpose?
A. 'This antibiotic syrup will prevent bladder infections while the
catheter is draining urine.'
B. 'This pain reliever will reduce the toddler's surgical incision pain
when he moves around.'
C. 'This medication will relax bladder spasms caused by the urinary
stent, reducing bladder irritability and pain.'
D. 'This stool softener will prevent constipation and straining during
bowel movements.'
Correct Answer: C
Clinical Rationale: Oxybutynin is an anticholinergic medication
frequently prescribed following hypospadias repair when a urinary
stent or catheter is present. Stents frequently irritate the bladder
trigone, causing painful bladder spasms characterized by sudden
lower abdominal discomfort, leakage around the catheter, and
drawing up of the legs. Oxybutynin relaxes the smooth muscle of the
bladder, alleviating these spasms. It is neither an antibiotic, a
primary analgesic, nor a stool softener.
Q3. A mother calls the pediatric urology clinic 3 days after her toddler
son underwent hypospadias repair with a stent in place (3). She reports
that the toddler has not passed urine through the stent for the past 4
hours, is extremely irritable, and has swelling of the penis. What is the
nurse's most appropriate initial action?
, A. Reassure the mother that urine output can fluctuate and advise
checking the diaper in another 2 hours.
B. Instruct the mother to administer a warm tub bath immediately to
relax the toddler and encourage voiding.
C. Advise the mother to bring the child to the clinic or emergency
department immediately for evaluation of stent obstruction.
D. Instruct the mother to gently flush the urinary stent with 3 mL of
sterile normal saline.
Correct Answer: C
Clinical Rationale: Absence of urine output through the stent for
several hours combined with irritability and penile swelling strongly
suggests stent occlusion (by mucus, blood clot, or kinking) or acute
urinary retention. This is an urgent surgical complication requiring
immediate provider evaluation. Flushed stents should never be
attempted by parents. Tub baths are contraindicated with active
stents.
Q4. During a discharge teaching session following hypospadias repair in
a toddler (4), the nurse discusses hygiene and bathing practices with the
parents. Which instruction is essential to include?
A. 'Give your child daily bubble baths to keep the perineal and diaper
region clean and fragrant.'
B. 'Avoid tub baths until the healthcare provider removes the urinary
stent and gives specific clearance; use sponge baths instead.'
C. 'Wash the penis vigorously with antibacterial soap and a washcloth
during every diaper change.'
D. 'Apply baby powder generously around the diaper area to absorb
moisture and prevent skin breakdown.'
Correct Answer: B
Clinical Rationale: Tub baths are strictly prohibited while a urinary
, stent or catheter is in place and until the surgical incision has
sufficiently epithelialized, because immersion in bathwater increases
the risk of ascending bacterial contamination into the urinary tract
and surgical wound. Sponge baths are recommended.
Q5. A nurse is educating the parents of a toddler discharged home
following hypospadias repair (5). Which of the following signs should
the nurse instruct the parents to report to the pediatric urology team
immediately?
A. Mild pink-tinged discoloration of urine draining into the diaper
during the first 24 to 48 hours.
B. Purulent, foul-smelling drainage at the surgical incision site and a
temperature of 38.5°C (101.3°F).
C. Slight localized edema and bruising of the penile shaft
postoperatively.
D. Gelling or yellowish crust formation along the suture line.
Correct Answer: B
Clinical Rationale: Fever combined with purulent, foul-smelling
drainage is a classic indicator of surgical site infection (SSI) or
urinary tract infection (UTI), requiring prompt medical evaluation
and likely antibiotic therapy. Mild hematuria and localized
edema/bruising are expected normal post-operative inflammatory
findings.
Q6. The mother of an active 2-year-old boy asks how to manage her
son's activity level during the 3-week recovery period following
hypospadias repair (6). What is the nurse's best recommendation?
A. Encourage participation in active running and playground games
to burn off toddler energy.
