STUDY GUIDE SYLLABUS & RESOURCE ANALYSIS
This study guide serves as a comprehensive educational companion for the HESI Pediatric and Obstetric Nursing Exam.
It represents a highly structured, thorough synthesis of core nursing knowledge, physiological principles, and critical clinical
application areas.
Major Examination Content Areas
• Pediatric Cardiovascular Health: Narrowed aortic lumen (coarctation), hypercyanotic 'tet' spells in Tetralogy of Fallot, digoxin
toxicity management (Digibind), and postoperative assessments.
• Pediatric Gastrointestinal & Nutritional Health: Pyloric stenosis metabolic imbalances (metabolic alkalosis), infantile
dehydration assessments (pulse, tear production), and solid food introduction readiness.
• Pediatric Respiratory & Infectious Health: RSV prevention (palivizumab/Synagis) for high-risk infants, bronchiolitis isolation
protocols, pertussis, varicella transmission precautions, and asthma rescue therapy.
• Oncology & Central Line Management: Acute myelocytic leukemia (AML), implanted port patency maintenance (saline/heparin
flushes), chemotherapy hypersensitivity reactions (PICC lines), and pediatric therapeutic play.
• Pediatric Renal & Genitourinary Disorders: Nephrotic syndrome therapeutic evaluation (IV albumin and periorbital edema),
hypospadias assessments, cryptorchidism, and recurrent urinary tract infections.
• Neuromuscular & Musculoskeletal Disorders: Duchenne muscular dystrophy genetics (X-linked recessive), acute
osteomyelitis clinical history, and rheumatic fever manifestations (Sydenham's chorea).
High-Yield Terminology & Procedures
• Consensual Eye Movement: Dual eye patching is mandatory for corneal foreign bodies to stop simultaneous movement of the
injured eye.
• Airborne & Contact Precautions: Required for active varicella lesions until all vesicles are crusted over.
• Chest Physiotherapy (CPT): Scheduled before meals and at bedtime to optimize pulmonary ventilation and avoid gastric
distress.
• LHRH Agonist Therapy: Normalizes peer-developmental differences in precocious puberty over several years.
Commonly Confused Concepts
• Cultural Practice vs. Physical Abuse: Symmetrical circular bruises typical of Chinese cupping therapy must be assessed
through cultural inquiry first rather than automatic abuse reporting.
• Adolescent Confidentiality (HIPAA): Upon the 18th birthday, clinical results cannot be shared with parents without the young
adult's explicit, signed permission.
• Anti-Epileptic Discontinuation: Requires a controlled tapering period of at least 2 weeks to prevent status epilepticus.

QUESTION 1: A mother brings her 8-month-old baby boy to the pediatric clinic because he has been vomiting
and experiencing diarrhea for the last 3 days. Which assessment is most important for the nurse to make
first?
A. Assess the infant's abdomen for tenderness
B. Determine if the infant was recently exposed to a virus
C. Measure the infant's pulse and heart rate
D. Evaluate the quality and pitch of the infant's cry
ANSWER ■: C — Measure the infant's pulse and heart rate
Explanation: In an infant with severe vomiting and diarrhea for 3 days, the priority is to assess for signs of dehydration and
cardiovascular compromise. An increased pulse rate (tachycardia) is one of the earliest and most sensitive physiological
indicators of hypovolemia and dehydration in infants. Assessing abdomen tenderness, viral exposure, or crying are important
but secondary to immediate cardiovascular assessment.
QUESTION 2: A mother brings her school-aged daughter to the pediatric clinic for evaluation of her
anti-epileptic medication regimen. Which information should the nurse provide to the mother regarding
discontinuation of these medications?
A. The medication dose will be tapered over a period of 2 weeks when being discontinued.
B. If seizures return, multiple medications will be prescribed for another 2 years.
C. A emergency dose of valproic acid (Depakote) should be available in the event of status epilepticus.
D. Phenytoin (Dilantin) and phenobarbital (Luminal) must be taken for life.
ANSWER ■: A — The medication dose will be tapered over a period of 2 weeks when being discontinued.
Explanation: Anti-epileptic medications must never be discontinued abruptly because sudden withdrawal can precipitate status
epilepticus or severe rebound seizures. Tapering the medication dose over a period of at least 2 weeks is the standard safe
protocol for discontinuation. Taking multiple medications for 2 years or taking them for life are not standard automatic rules.

QUESTION 3: A male toddler is brought to the emergency center approximately three hours after swallowing
tablets from his grandmother's bottle of digoxin (Lanoxin). Which prescription should the nurse implement
first?
A. Administer activated charcoal orally
B. Prepare and perform gastric lavage
C. Obtain a 12-lead electrocardiogram
D. Administer IV digoxin immune fab (Digibind)
ANSWER ■: D — Administer IV digoxin immune fab (Digibind)
Explanation: Digoxin immune fab (Digibind) is the specific antidote for severe, life-threatening digoxin toxicity. Since the child
ingested the tablets three hours ago, the drug has already been absorbed into the systemic circulation, making gastric lavage or
activated charcoal secondary. Digibind binds to systemic digoxin and renders it inactive, directly resolving toxicity. A 12-lead
ECG is important but secondary to the administration of the life-saving antidote.
QUESTION 4: An 8-year-old male client with nephrotic syndrome is receiving salt-poor human albumin IV.
Which finding indicates to the nurse that the child is manifesting a therapeutic response to this medication?
A. Decreased urinary output
B. Decreased periorbital edema
C. Increased periods of rest
D. Weight gain of 0.5 kg/day
ANSWER ■: B — Decreased periorbital edema
Explanation: In nephrotic syndrome, glomerular damage causes severe proteinuria and hypoalbuminemia, leading to
decreased oncotic pressure and fluid shifting into the tissues (manifesting as severe periorbital and generalized edema). IV
administration of salt-poor human albumin increases intravascular oncotic pressure, drawing fluid back from the interstitial
tissues into the blood vessels. This results in diuresis, weight loss, and a decrease in edema (such as periorbital edema).
Weight gain or decreased urinary output would indicate worsening fluid retention, not a therapeutic response.
