A nurse is caring for a newborn who may have pyloric stenosis.
Which of the following manifestations should the nurse expect?
Presence of Dance sign.
Projectile vomiting.
Always seems full.
Excessive weight gain.
The Correct Answer is B
Pyloric stenosis involves hypertrophy of the pyloric sphincter, causing gastric outlet obstruction. Understanding the mechanical nature of this obstruction is necessary to identify the classic signs of retrograde flow and the resulting nutritional and fluid volume deficits in infants.
Choice A rationale
Dance sign refers to a physical finding in intussusception where the right lower quadrant feels empty. It is not associated with pyloric stenosis, which typically presents with an olive-shaped mass in the right upper quadrant instead.
Choice B rationale
Projectile vomiting occurs because the hypertrophied pylorus prevents gastric emptying into the duodenum. Pressure builds within the stomach until the contents are forcefully expelled, typically occurring shortly after feeding and lacking bile in the emesis.
Choice C rationale
Infants with pyloric stenosis are typically hungry and eager to feed immediately after vomiting. Because the food cannot pass into the small intestine for absorption, the child remains in a state of constant caloric deprivation.
Choice D rationale
Excessive weight gain is impossible in pyloric stenosis due to the inability to digest and absorb nutrients. Most infants present with significant weight loss, dehydration, and failure to thrive because of the persistent, forceful vomiting.

Correct Answer is A
Explanation
Safety management for pediatric patients with seizure disorders focuses on preventing injury during high-risk activities. Applying knowledge of environmental hazards during water immersion is vital to prevent drowning, which can occur rapidly if a seizure happens in the water.
Choice A rationale
Constant, direct adult supervision is the gold standard for water safety in children with epilepsy. An adult can immediately intervene to keep the child's airway above water if a sudden loss of consciousness or convulsion occurs.
Choice B rationale
Peers of the same age lack the physical strength, judgment, and rescue training necessary to manage a submerged seizing child. Reliance on friends creates a false sense of security and significantly increases the risk of a fatal drowning.
Choice C rationale
Drowning can occur in even very shallow water during a seizure if the child falls face down and cannot right themselves. Shallow water does not eliminate the need for vigilant, one-on-one supervision by a competent adult.
Choice D rationale
While a life jacket provides buoyancy, it may not prevent the aspiration of water if a child is seizing and unable to maintain an upright position. Flotation devices are supplementary and never replace the necessity of supervision.
Correct Answer is A
Explanation
Identifying developmental delays in toddlers requires the application of pediatric growth benchmarks and the nursing process. Prioritization hinges on interdisciplinary communication to validate clinical observations before initiating specific interventions, ensuring the diagnostic process is medically accurate and collaborative.
Choice A rationale
Effective clinical practice necessitates that assessment data are verified by the primary provider to establish a formal diagnosis. This communication ensures that the medical plan of care is adjusted based on accurate, professional interpretation of developmental milestones.
Choice B rationale
Social work referrals for early intervention are critical secondary actions once a delay is formally identified. While these services support long-term outcomes, they cannot precede the medical validation and formal referral process initiated by the healthcare team.
Choice C rationale
Education is premature before a definitive diagnosis is made by the provider. Providing specific information about delays before confirmation may cause unnecessary parental anxiety and violates the sequence of the nursing process regarding assessment and diagnosis.
Choice D rationale
Support groups provide emotional and community resources for families dealing with established diagnoses. However, this is a supportive intervention rather than a clinical priority during the initial assessment phase when diagnostic certainty is still being pursued.
