A nurse is assessing a 6-month-old male infant with hypospadias. Which assessment finding would the nurse expect to observe?

해설
Hypospadias is characterized by a urethral opening on the ventral surface of the penis. Other options describe dorsal location (epispadias), absent foreskin (not typical), or upward curvature (not specific to hypospadias).

Core Nursing Explanation Key Concept Analysis: This question tests your knowledge of the congenital anomaly Hypospadias. Hypospadias is a condition where the urethral meatus (opening) is abnormally located on the ventral (underside) of the penis, anywhere from just below the tip to the base of the shaft or even the scrotum. This occurs due to incomplete fusion of the urethral folds during fetal development. The nurse's role includes accurate assessment and preoperative/postoperative care.

Answer Rationale: Key Point! The defining characteristic of hypospadias is a ventrally displaced urethral opening. Therefore, when assessing a 6-month-old infant with this diagnosis, the nurse would expect to observe the urethral opening on the ventral surface. This finding is the primary basis for the diagnosis.

Distractor Analysis:
Watch out for confusion! Option ① describes the urethral opening on the dorsal surface. This is characteristic of Epispadias, a much rarer and often more severe condition that may be associated with bladder exstrophy. Do not confuse "hypo-" (under, ventral) with "epi-" (upon, dorsal).
Option ③ states the foreskin is completely absent from birth. This is not typical for hypospadias. In fact, hypospadias is often associated with a dorsal hood of foreskin (the foreskin is incomplete on the ventral side, giving it a hooded appearance), not a complete absence.
Option ④ describes the penis curving upward during erection. This is incorrect. A common associated finding with hypospadias is Chordee, which is a ventral curvature of the penis (it curves downward, not upward). This curvature is caused by fibrous tissue on the ventral side.

Related Concepts: Understanding hypospadias is crucial for pediatric and surgical nursing. Key nursing considerations include: never performing circumcision on an infant with hypospadias (the foreskin may be used for surgical repair), assessing for associated conditions like cryptorchidism (undescended testis), and providing family education about the planned surgical correction, which is typically performed between 6-18 months of age.
Concept Summary
TermDefinition & Key Feature
HypospadiasCongenital defect where urethral meatus opens on VENTRAL surface of penis.
EpispadiasRare defect where urethral meatus opens on DORSAL surface of penis.
ChordeeVentral curvature of penis, often associated with hypospadias.
Dorsal HoodIncomplete foreskin on ventral side, common in hypospadias.

Anatomy, Physiology & Pharmacology Points Embryology: The urethra forms between 8-14 weeks gestation via fusion of the urethral folds along the ventral midline. Hypospadias results from incomplete fusion. The location of the meatus determines the classification: glandular (tip), coronal, penile shaft, penoscrotal, or perineal.
Surgical Goal: Repair involves straightening the chordee (if present) and creating a urethral tube to bring the meatus to the tip of the glans, often using the existing foreskin tissue.
Memory Tips Mnemonic: "HYPOspadias is LOW (ventral)." Think: "Hypo" means low, so the opening is low on the penis.
Visual Association: Imagine the penis. The side you see when looking down is dorsal. The underside is ventral. Hypospadias = hole on the underside.
High-Frequency NCLEX Topics Hypospadias is a classic pediatric genitourinary topic. The NCLEX expects you to: 1) Identify the assessment finding, 2) Know the critical nursing action (DO NOT CIRCUMCISE), and 3) Understand the timing and purpose of surgical repair. It's often tested in comparison to epispadias.
Watch Out for Question Variations! The same concept can be tested as:
1. Priority Intervention: "The nurse is preparing a 2-month-old with hypospadias for discharge. Which parent statement requires immediate correction?" (Answer: "We will schedule his circumcision next month.")
2. Post-op Care: "Following hypospadias repair, which finding should the nurse report immediately?" (Answer: Signs of urinary obstruction or catheter blockage.)
3. Teaching Focus: "What is the primary goal of hypospadias repair surgery?" (Answer: To allow the child to void standing up with a straight stream and normal appearance.)

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are a nurse in a pediatric clinic. During a routine 6-month well-baby visit, the mother mentions she's noticed her son's "pee hole" seems to be "on the bottom side" of his penis, and the skin on top looks like a hood. The infant has not been circumcised.

Nursing Intervention Strategy: 1. Assessment: Perform a gentle, visual genital assessment. Confirm the ventral location of the meatus. Note any associated chordee (curvature) and check for bilateral descended testes. Document findings accurately. 2. Education & Reassurance: Explain the diagnosis of hypospadias to the parents in simple terms. Reassure them it is a common, correctable condition. Emphasize that Key Point! the infant must NOT be circumcised, as the foreskin is essential tissue for the future surgical repair. 3. Collaboration & Planning: Refer the family to a pediatric urologist. Discuss the typical surgical timeline (often between 6-18 months) and the goals of surgery (functional and cosmetic correction).

Patient Safety and Precautions: - Critical Alert: Place a prominent note in the chart and educate all caregivers: "NO CIRCUMCISION." This is the single most important safety precaution. - Post-operatively, common complications include fistula formation (leakage), meatal stenosis (narrowing), and urinary retention. Meticulous care of the urinary stent or catheter is essential.
Nursing Procedure & Medication Flow Post-Operative Care after Hypospadias Repair: 1. Catheter/Stent Care: The child will have a urinary diversion (e.g., urethral stent, suprapubic tube). Maintain patency and securement. Record output accurately. 2. Bladder Spasm Management: Anticholinergic medications (e.g., oxybutynin) are often prescribed. Administer as scheduled to prevent painful spasms that can disrupt healing. 3. Wound Care: Keep the surgical site clean and dry. Apply antibiotic ointment as ordered. Use double diapering or a protective barrier to keep urine/feces away from the dressing. 4. Pain Management: Administer analgesics (e.g., acetaminophen, ibuprofen) on a schedule to keep the child comfortable, which promotes healing.
A Word from Your Senior Nurse "Assessing a newborn or infant's genitals is a standard part of your nursing assessment, and catching a finding like hypospadias early makes a huge difference for that child's outcome. Your knowledge directly prevents a harmful error—an unnecessary circumcision. In pediatrics, you're caring for the child and guiding the anxious parents. Your calm, educated explanation can turn their worry into a plan. Remember: 'Hypo is low, Epi is high, and never, ever circumcise!' That's clinical wisdom that protects your patient."

  • Hypospadias — A congenital condition where the urethral opening is located on the ventral (underside) surface of the penis.
  • Epispadias — A rare congenital defect where the urethral opening is located on the dorsal (topside) surface of the penis.
  • Chordee — A ventral curvature of the penis, often associated with hypospadias, caused by fibrous tissue.
  • Urethral Meatus — The external opening of the urethra, through which urine exits the body.
  • Dorsal Hood — The characteristic appearance of the foreskin in hypospadias, where it is incomplete on the ventral side, forming a hood over the glans.
