Neonatal/Pediatric Specialty (NPS) Examination — Questions and Answers

Question 1: What is the maximum safe concentration of dextrose that should be administered via a peripheral IV in a neonate?

D15W (15%)
D5W (5%)
D12.5W (12.5%) (Correct answer)
D10W (10%)

Correct answer: D12.5W (12.5%)

Dextrose concentrations up to 12.5% are considered safe for peripheral IV administration in neonates to avoid venous irritation and extravasation injury.

Question 2: What is the primary purpose of performing a Silverman-Anderson score on a neonate?

To assess gestational age
To determine the need for surfactant therapy
To evaluate the severity of respiratory distress (Correct answer)
To monitor oxygen saturation levels

Correct answer: To evaluate the severity of respiratory distress

The Silverman-Anderson score is a clinical assessment tool specifically designed to quantify the severity of respiratory distress in neonates. It evaluates five parameters related to respiratory effort, such as nasal flaring and retractions. A higher score indicates more severe respiratory distress, which helps guide appropriate medical interventions and monitoring.

Question 3: During neonatal transport, maintaining normothermia is critical. What is the target core temperature range for a sick neonate?

38.5–39°C
37.5–38.5°C
34–35°C
36–37.5°C (Correct answer)

Correct answer: 36–37.5°C

Neonatal normothermia target is 36–37.5°C axillary; hypothermia increases oxygen consumption, metabolic acidosis, surfactant dysfunction, and mortality.

Question 4: What is the primary advantage of nasal CPAP (nCPAP) over mechanical ventilation for preterm neonates with mild-moderate RDS?

Avoidance of intubation and reduced BPD risk (Correct answer)
Higher oxygen delivery
Easier nursing care
More precise tidal volume control

Correct answer: Avoidance of intubation and reduced BPD risk

nCPAP avoids the trauma of intubation and reduces the incidence of bronchopulmonary dysplasia by recruiting alveoli non-invasively.

Question 5: What is the mechanism of action of milrinone when used in neonates with low cardiac output?

Calcium channel blocker
Phosphodiesterase-3 inhibitor (Correct answer)
Beta-1 adrenergic agonist
Alpha-1 adrenergic agonist

Correct answer: Phosphodiesterase-3 inhibitor

Milrinone inhibits phosphodiesterase-3, increasing intracellular cAMP, resulting in positive inotropy, lusitropy, and pulmonary/systemic vasodilation.

Question 6: A term neonate is noted to have a 'double bubble' sign on abdominal X-ray. What is the most likely diagnosis?

Pyloric stenosis
Duodenal atresia (Correct answer)
Meconium ileus
Hirschsprung disease

Correct answer: Duodenal atresia

The 'double bubble' sign (distended stomach + dilated proximal duodenum with no distal gas) is pathognomonic for duodenal atresia.

Question 7: Dexamethasone is used postnatally in premature neonates primarily to treat which condition?

Hypoglycemia
Necrotizing enterocolitis
Intraventricular hemorrhage
Bronchopulmonary dysplasia (Correct answer)

Correct answer: Bronchopulmonary dysplasia

Low-dose postnatal dexamethasone is used to facilitate extubation and manage bronchopulmonary dysplasia in ventilator-dependent preterm neonates.

Question 8: A term neonate presents with tachypnea, mild hypoxia, and a chest X-ray showing fluid in the horizontal fissure and perihilar streaking. What is the most likely diagnosis?

Meconium aspiration syndrome
Transient tachypnea of the newborn (TTN) (Correct answer)
Pneumothorax
Neonatal pneumonia

Correct answer: Transient tachypnea of the newborn (TTN)

TTN results from delayed resorption of fetal lung fluid and presents with tachypnea and perihilar streaking/fissure fluid on CXR, typically resolving within 24–72 hours.

Question 9: What is the correct dose of epinephrine for neonatal cardiac arrest via the endotracheal route?

0.3–0.5 mg/kg
0.01–0.03 mg/kg
0.1–0.3 mg/kg
0.05–0.1 mg/kg (Correct answer)

Correct answer: 0.05–0.1 mg/kg

The ET dose of epinephrine in neonatal resuscitation is 0.05–0.1 mg/kg (higher than IV) due to poor absorption via the tracheal route.

Question 10: A nurse notes that a 6-hour-old neonate has cyanotic hands and feet. Which of the following actions by the nurse is appropriate?

Place child in an isolette.
Swaddle baby in a blanket. (Correct answer)
Apply pulse oximeter.
Administer oxygen.

Correct answer: Swaddle baby in a blanket.

Cyanotic hands and feet (acrocyanosis) are a common and normal finding in newborns during the first 24-48 hours of life, especially if they are slightly cool. This is due to immature peripheral circulation. Swaddling the baby in a blanket will help warm the infant and improve peripheral circulation, which is the appropriate initial action for this benign condition.

Question 11: A neonate develops a sudden deterioration on mechanical ventilation. The NPS performs a DOPE assessment. What does 'D' stand for?

Decreased breath sounds
Displacement of the ETT (Correct answer)
Drug effect
Diaphragm weakness

Correct answer: Displacement of the ETT

The DOPE mnemonic for sudden deterioration on a ventilator stands for Displacement, Obstruction, Pneumothorax, and Equipment failure.

Question 12: A 7 year-old child was rescued from a burning building and brought to the ED for treatment. Upon arrival, the child was placed on oxygen via a non-rebreather mask. The neonatal/pediatric specialist notes that when the child inhales, the reservoir bag remains completely inflated. The specialist should?

Adjust the seal on the face mask (Correct answer)
Change the patient to an air-entrainment mask
Increase the oxygen flow
Monitor the patient with pulse oximetry

Correct answer: Adjust the seal on the face mask

For a non-rebreather mask to function correctly, the reservoir bag should slightly deflate with each inspiration and then reinflate. If the reservoir bag remains completely inflated during inhalation, it indicates that the mask is not forming a tight seal on the patient's face. This allows room air to be drawn in, diluting the oxygen and preventing the delivery of a high concentration. Adjusting the seal is necessary for proper function.

Question 13: Which bundle component is most evidence-based for preventing ventilator-associated events (VAE) in mechanically ventilated neonates?

Prophylactic antibiotics throughout the duration of mechanical ventilation
Routine instillation of normal saline before endotracheal suctioning
Routine chest physiotherapy every 4 hours
Closed suctioning systems combined with appropriate head-of-bed elevation when feasible (Correct answer)

Correct answer: Closed suctioning systems combined with appropriate head-of-bed elevation when feasible

Closed suctioning systems reduce contamination risk during suctioning, and head-of-bed elevation reduces aspiration risk; both are evidence-based VAP prevention bundle components.

Question 14: What is the normal fetal hemoglobin (HbF) percentage in a term newborn at birth?

60–80% (Correct answer)
30–40%
10–20%
90–100%

Correct answer: 60–80%

At birth, fetal hemoglobin (HbF) comprises approximately 60–80% of total hemoglobin in term newborns, gradually replaced by adult HbA over the first year.

Question 15: A neonatologist believes continued intensive care for a 24-week neonate is futile. The parents disagree. What is the most appropriate next step?

Continue all interventions without further discussion
Transfer the patient to another institution immediately
Withdraw care based on the physician's medical judgment alone
Convene an ethics committee consultation to facilitate discussion (Correct answer)

Correct answer: Convene an ethics committee consultation to facilitate discussion

Ethics committee consultation provides a structured, multidisciplinary forum to facilitate communication, explore values, and find consensus when clinicians and families disagree about care goals.

Question 16: What is the minimum recommended duration of antibiotic therapy for confirmed gram-negative neonatal bacterial meningitis?

10–14 days
14–21 days
21 days minimum (Correct answer)
7 days

Correct answer: 21 days minimum

Gram-negative neonatal bacterial meningitis requires a minimum of 21 days of antibiotic therapy due to the severity of infection, high mortality risk, and potential for relapse.

Question 17: Which element of the central line insertion bundle is considered most critical for CLABSI prevention?

Selecting the femoral vein as the preferred insertion site
Routine catheter replacement every 72 hours
Maximal sterile barrier precautions during catheter insertion (Correct answer)
Prophylactic antibiotic administration at time of insertion

Correct answer: Maximal sterile barrier precautions during catheter insertion

Maximal sterile barrier precautions — cap, mask, sterile gown, sterile gloves, and full-body sterile drape — at the time of insertion are the most effective bundle component for preventing CLABSI.

Question 18: Meconium aspiration syndrome (MAS) is characterized by which pathophysiological mechanism?

Bacterial pneumonia from GBS
Surfactant excess with alveolar overdistension
Airway obstruction, surfactant inactivation, and chemical pneumonitis (Correct answer)
Pulmonary hypoplasia from oligohydramnios

Correct answer: Airway obstruction, surfactant inactivation, and chemical pneumonitis

MAS causes a ball-valve airway obstruction, inactivates surfactant, triggers chemical pneumonitis, and often leads to pulmonary hypertension.

Question 19: A neonate in the NICU suddenly develops cyanosis, bradycardia, and absent breath sounds on the left. Chest transillumination is positive. What is the immediate intervention?

Increase PEEP on the ventilator
Administer epinephrine IV
Needle decompression of the left chest at the 2nd intercostal space, midclavicular line (Correct answer)
Chest X-ray to confirm diagnosis

Correct answer: Needle decompression of the left chest at the 2nd intercostal space, midclavicular line

A tension pneumothorax in a neonate requires immediate needle decompression at the 2nd ICS, MCL on the affected side — waiting for X-ray confirmation is inappropriate.

Question 20: A neonate with congenital diaphragmatic hernia (CDH) is intubated at birth. Why is bag-mask ventilation avoided in CDH?

It causes bradycardia
It increases pulmonary vascular resistance
It inflates herniated bowel, worsening lung compression (Correct answer)
It delivers too much oxygen

Correct answer: It inflates herniated bowel, worsening lung compression

Bag-mask ventilation forces air into the stomach and herniated intestinal loops, further compressing the hypoplastic lung and worsening respiratory failure.

Question 21: What is the primary function of a pulse oximeter in neonatal and pediatric care?

To measure blood pressure
To measure respiratory rate
To monitor heart rate
To assess oxygen saturation levels (Correct answer)

Correct answer: To assess oxygen saturation levels

A pulse oximeter is a non-invasive device that measures the oxygen saturation of hemoglobin in arterial blood (SpO2). It is a critical tool in neonatal and pediatric care for continuously monitoring a patient's oxygenation status. This allows clinicians to detect hypoxemia early and guide appropriate oxygen therapy or respiratory support.

Question 22: A mother with active, untreated pulmonary tuberculosis delivers a term neonate. What is the recommended approach regarding breastfeeding?

Breastfeeding is permanently contraindicated with active TB
Breastfeeding should be deferred until the mother has received at least 2 weeks of effective anti-TB therapy and is non-infectious (Correct answer)
The mother should pump and discard milk until culture negativity is confirmed
Breastfeeding is safe and should begin immediately

Correct answer: Breastfeeding should be deferred until the mother has received at least 2 weeks of effective anti-TB therapy and is non-infectious

Breastfeeding should be temporarily postponed until the mother has completed at least 2 weeks of effective anti-TB therapy and is considered non-infectious to prevent respiratory transmission to the neonate.

Question 23: Which parameter primarily determines oxygenation in a neonate on high-frequency oscillatory ventilation (HFOV)?

Amplitude (ΔP)
Mean airway pressure (MAP) (Correct answer)
Inspiratory time
Frequency (Hz)

Correct answer: Mean airway pressure (MAP)

Mean airway pressure (MAP) is the primary determinant of lung recruitment and oxygenation in HFOV, while amplitude controls CO2 elimination.

Question 24: A neonate has persistent metabolic acidosis with an elevated anion gap. Which condition should be suspected?

Inborn error of metabolism (Correct answer)
Normal anion gap acidosis from diarrhea
Hypoalbuminemia
Respiratory alkalosis from hyperventilation

Correct answer: Inborn error of metabolism

An elevated anion gap metabolic acidosis in a neonate raises concern for inborn errors of metabolism (e.g., organic acidemias, maple syrup urine disease, or congenital lactic acidosis).

Question 25: A full-term newborn was just born. Which nursing intervention is important for the nurse to perform first?

Remove wet blankets. (Correct answer)
Elicit the Moro reflex
Assess Apgar score.
Insert eye prophylaxis.

Correct answer: Remove wet blankets.

The most immediate and critical nursing intervention for a newborn is to prevent heat loss, as neonates are highly susceptible to hypothermia. Removing wet blankets and replacing them with warm, dry ones helps maintain the infant's core body temperature. Maintaining thermal stability is paramount for metabolic function and overall well-being, preceding other assessments or interventions.

Question 26: A 28-week neonate receives vancomycin for suspected sepsis. Which pharmacokinetic parameter is most commonly monitored to guide dosing?

Volume of distribution
AUC/MIC ratio (Correct answer)
Peak concentration
Half-life

Correct answer: AUC/MIC ratio

AUC/MIC-guided vancomycin monitoring (targeting AUC 400–600) is now preferred over trough-only monitoring in neonates and pediatric patients.

Question 27: What is the correct sequence for managing a neonate with meconium-stained amniotic fluid who is non-vigorous at birth?

Routine care, dry, and stimulate before further assessment
Immediate intubation only if SpO2 falls below 85%
Initiate PPV immediately without tracheal suctioning (Correct answer)
Immediate direct laryngoscopy and tracheal suctioning before initiating PPV

Correct answer: Initiate PPV immediately without tracheal suctioning

Current NRP guidelines recommend initiating PPV immediately for non-vigorous meconium-stained neonates rather than routine tracheal suctioning, which has not been shown to improve outcomes.

Question 28: A transport team prepares to move a neonate with confirmed pertussis. What isolation precautions are required during transport?

Contact precautions only
Droplet precautions (Correct answer)
Airborne precautions with N95 respirator
Standard precautions only

Correct answer: Droplet precautions

Pertussis (Bordetella pertussis) is transmitted by large respiratory droplets; droplet precautions with surgical mask and eye protection are required for healthcare workers within 3 feet of the patient.

Question 29: What is the appropriate size endotracheal tube (uncuffed) for a term neonate?

2.0 mm
4.0 mm
3.0–3.5 mm (Correct answer)
2.5 mm

Correct answer: 3.0–3.5 mm

Term neonates (approximately 3–4 kg) are intubated with a 3.0–3.5 mm uncuffed ETT; tube size can be estimated as weight (kg)/3 + 2.5 for neonates.

Question 30: What is the primary purpose of developmental care practices such as NIDCAP (Newborn Individualized Developmental Care and Assessment Program)?

To individualize care based on each neonate's behavioral cues to reduce stress and support neurodevelopment (Correct answer)
To eliminate parental involvement during acute illness phases
To quantify nursing workload for staffing decisions
To standardize care protocols across all NICU nurses

Correct answer: To individualize care based on each neonate's behavioral cues to reduce stress and support neurodevelopment

NIDCAP uses systematic observation of behavioral cues to tailor care timing, positioning, and environmental stimulation to each neonate's neurodevelopmental tolerance.

Question 31: According to the AAP guidelines, at what gestational age is resuscitation at birth generally considered optional based on parental preference?

24–25 weeks
20–21 weeks
26–28 weeks
22–23 weeks (Correct answer)

Correct answer: 22–23 weeks

The AAP considers 22–23 weeks a 'gray zone' where resuscitation is ethically optional; at 22 weeks, survival is rare and morbidity near-universal, making parental choice central.

Question 32: According to the WHO 'Five Moments for Hand Hygiene,' at which moments must hand hygiene be performed?

Before patient contact, before aseptic procedures, after body fluid exposure, after patient contact, and after contact with patient surroundings (Correct answer)
Before and after patient contact only
At the start and end of each shift only
Before aseptic procedures and after body fluid exposure only

Correct answer: Before patient contact, before aseptic procedures, after body fluid exposure, after patient contact, and after contact with patient surroundings

The WHO Five Moments framework identifies all five critical points in patient care that require hand hygiene to comprehensively prevent pathogen transmission.

Question 33: The correct compression-to-ventilation ratio during neonatal CPR is:

15:2
30:2
3:1 (Correct answer)
5:1

Correct answer: 3:1

NRP recommends a 3:1 compression-to-ventilation ratio (90 compressions + 30 breaths per minute) for neonatal CPR to prioritize ventilation in asphyxia-driven cardiac arrest.

Question 34: Which pathogen is most commonly identified in NICU central line-associated bloodstream infections (CLABSI)?

Klebsiella pneumoniae
Candida albicans
Coagulase-negative Staphylococcus (Correct answer)
Escherichia coli

Correct answer: Coagulase-negative Staphylococcus

Coagulase-negative Staphylococcus is the most frequently isolated CLABSI pathogen in the NICU due to its ability to adhere and form biofilms on catheter surfaces.

Question 35: Which intervention is most effective in preventing catheter-associated urinary tract infections (CAUTI) in neonates?

Scheduled catheter changes every 48 hours
Routine prophylactic antibiotics during catheterization
Removing urinary catheters as soon as they are no longer clinically necessary (Correct answer)
Daily catheter irrigation with antiseptic solution

Correct answer: Removing urinary catheters as soon as they are no longer clinically necessary

Duration of catheterization is the strongest independent risk factor for CAUTI; timely removal when the catheter is no longer clinically indicated is the most effective prevention strategy.

Question 36: What is the recommended empirical antibiotic regimen for early-onset neonatal sepsis in a term neonate?

Meropenem and vancomycin
Ampicillin and gentamicin (Correct answer)
Vancomycin and cefotaxime
Clindamycin and azithromycin

Correct answer: Ampicillin and gentamicin

Ampicillin and gentamicin is the standard first-line empirical regimen for early-onset sepsis, providing coverage for the predominant pathogens: Group B Streptococcus, Listeria monocytogenes, and gram-negative enteric organisms.

Question 37: Which medication is used to treat neonatal seizures as first-line therapy in the US?

Levetiracetam
Phenobarbital (Correct answer)
Fosphenytoin
Lorazepam

Correct answer: Phenobarbital

Phenobarbital at 20 mg/kg IV is the established first-line anticonvulsant for neonatal seizures in most US centers.

Question 38: Which of the following devices is most commonly used for administering surfactant therapy to neonates?

CPAP machine
Endotracheal tube (Correct answer)
Nasal cannula
Mechanical ventilator

Correct answer: Endotracheal tube

Surfactant therapy is administered directly into the lungs to replace deficient natural surfactant, primarily in premature neonates with Respiratory Distress Syndrome (RDS). This is typically achieved by instilling the surfactant solution through an endotracheal tube, which allows for direct and effective delivery to the lower airways and alveoli where it is needed.

Question 39: Which surfactant is administered intratracheally as a natural bovine-derived preparation for neonatal RDS?

Calfactant (Infasurf)
All of the above (Correct answer)
Poractant alfa (Curosurf)
Beractant (Survanta)

Correct answer: All of the above

Beractant, calfactant, and poractant alfa are all natural animal-derived surfactants approved for intratracheal administration in neonatal RDS.

Question 40: A 28-week gestational age neonate presents with grunting, nasal flaring, and intercostal retractions. What is the most likely diagnosis?

Congenital diaphragmatic hernia
Transient tachypnea of the newborn
Meconium aspiration syndrome
Respiratory distress syndrome (RDS) (Correct answer)

Correct answer: Respiratory distress syndrome (RDS)

Respiratory distress syndrome (RDS) is highly common in premature neonates, especially those born at 28 weeks gestation, due to insufficient surfactant production in their immature lungs. The presented symptoms of grunting, nasal flaring, and intercostal retractions are classic signs of increased work of breathing characteristic of RDS. Other options are less likely given the specific gestational age and clinical presentation.

Question 41: A neonatal/pediatric specialist is called to the ED to administer a bronchodilator to a 7-year-old child with asthma. The child is on oxygen via nasal cannula at 2L/min. Pulse oximetry reveals a saturation of 84%. The specialist finds the end of the oxygen tubing under the chair of the mother at the bedside. The specialist reattaches the tubing and notes that the SpO2 is now 93%. The specialist should?

Contact the ED physician
Increase the oxygen flow
Change the device to a non-rebreather mask
Maintain the current oxygen flow (Correct answer)

Correct answer: Maintain the current oxygen flow

The patient's SpO2 improved from 84% to 93% after reattaching the oxygen tubing, which is within an acceptable and safe range for oxygen saturation. Since the immediate problem (dislodged tubing) has been resolved and the patient's oxygenation is now adequate, maintaining the current oxygen flow is the appropriate action. There is no indication to increase flow or change devices unless the SpO2 drops again.

Question 42: A 15-year-old patient with asthma presents to the ED in moderate distress. After several hours of treatment, no clinical improvement has occurred. The physician has ordered heliox therapy. Which of the following should the neonatal/pediatric specialist select for delivery of this therapy?

Nasal cannula
High-flow cannula
Non-rebreather mask (Correct answer)
Air entrainment mask

Correct answer: Non-rebreather mask

Heliox therapy is typically administered via a tight-fitting non-rebreather mask to ensure the delivery of the precise heliox mixture and minimize entrainment of room air. This mask provides a high concentration of the therapeutic gas, which is crucial for reducing airway resistance and improving gas flow in patients with severe asthma who are in moderate distress.

Question 43: A neonate with persistent pulmonary hypertension (PPHN) fails conventional therapy. Which inhaled medication is indicated?

Bosentan
Nitric oxide (iNO) (Correct answer)
Sildenafil
Epoprostenol

Correct answer: Nitric oxide (iNO)

Inhaled nitric oxide (iNO) is the only FDA-approved inhaled pulmonary vasodilator for neonates with PPHN, selectively reducing pulmonary vascular resistance.

Question 44: Which of the following is a sign of increased work of breathing in a pediatric patient?

Eupnea
Regular respiratory rate
Clear breath sounds
Subcostal retractions (Correct answer)

Correct answer: Subcostal retractions

Subcostal retractions are a clear sign of increased work of breathing in a pediatric patient. This occurs when the child uses accessory muscles, pulling the skin inward below the rib cage, to overcome airway resistance or decreased lung compliance. It indicates that the respiratory system is working harder than normal to achieve adequate ventilation.

Question 45: Which model of care best supports family involvement during rounds in the NICU?

Family-integrated care (FICare) with parents participating in daily bedside rounds (Correct answer)
Conducting rounds outside the room to maintain privacy
Limiting family rounds participation to attending physicians only
Weekly family meetings separate from daily rounds

Correct answer: Family-integrated care (FICare) with parents participating in daily bedside rounds

Family-Integrated Care (FICare) incorporates parents as active participants in daily rounds, care decisions, and hands-on care, improving outcomes and parental competence.

Question 46: A neonate is confirmed to have RSV bronchiolitis. What isolation precautions should be implemented?

Contact and droplet precautions combined (Correct answer)
Contact precautions only
Droplet precautions only
Airborne precautions with N95 respirator

Correct answer: Contact and droplet precautions combined

RSV is transmitted by both large respiratory droplets and direct or indirect contact, requiring combined contact and droplet precautions to prevent spread.

Question 47: A neonate on HFOV has a rising PaCO2. Which ventilator parameter should be increased?

Mean airway pressure (MAP)
Inspired oxygen (FiO2)
Amplitude (ΔP) (Correct answer)
Frequency (Hz)

Correct answer: Amplitude (ΔP)

Amplitude (ΔP) determines tidal volume delivery in HFOV; increasing amplitude improves CO2 elimination and lowers PaCO2.

Question 48: Which sign indicates that a pediatric patient in shock has transitioned from compensated to decompensated shock?

Prolonged capillary refill
Bounding pulses
Tachycardia
Hypotension (Correct answer)

Correct answer: Hypotension

Hypotension marks the transition to decompensated shock in pediatric patients; children can maintain blood pressure for extended periods through vasoconstriction before decompensating.

Question 49: Which ventilation mode delivers a set tidal volume regardless of changes in lung compliance in mechanically ventilated neonates?

Volume-guaranteed ventilation (VG) (Correct answer)
High-frequency oscillatory ventilation (HFOV)
Pressure-controlled ventilation (PCV)
Synchronized intermittent mandatory ventilation (SIMV)

Correct answer: Volume-guaranteed ventilation (VG)

Volume-guaranteed ventilation delivers a clinician-set tidal volume by adjusting inspiratory pressure breath-by-breath, protecting against volutrauma as compliance changes.

Question 50: A neonate with trisomy 18 is born with multiple severe anomalies. The parents request full resuscitation. What is the most appropriate provider response?

Honor parental wishes while providing honest prognostic information and offering palliative care as an option (Correct answer)
Resuscitate without discussion to avoid conflict
Refuse resuscitation as trisomy 18 is universally fatal
Refer decision to hospital ethics board before delivery

Correct answer: Honor parental wishes while providing honest prognostic information and offering palliative care as an option

Current evidence shows some trisomy 18 infants can survive with aggressive intervention; providers should share accurate outcome data while respecting parental values and offering all options including palliative care.

Question 51: What is the target oxygen saturation range recommended for preterm neonates less than 32 weeks gestation?

91–95% (Correct answer)
85–89%
100%
96–99%

Correct answer: 91–95%

Current evidence supports targeting SpO2 of 91–95% in preterm neonates <32 weeks to balance risks of retinopathy of prematurity and mortality.

Question 52: NICU noise levels above which threshold are considered potentially harmful to neurodevelopment in preterm neonates?

45 dB
55 dB (Correct answer)
65 dB
40 dB

Correct answer: 55 dB

The AAP recommends NICU sound levels not exceed 45–50 dB (continuous) or 65 dB (transient peak) to protect the developing auditory system and prevent noise-induced stress.

Question 53: Why does therapeutic hypothermia (TH) reduce brain injury in hypoxic-ischemic encephalopathy (HIE)?

It increases cerebral blood flow during cooling
It reduces oxygen consumption in the brain during acute hypoxia
It attenuates the secondary energy failure phase by suppressing glutamate excitotoxicity and apoptosis (Correct answer)
It prevents seizures by reducing neuronal firing rates

Correct answer: It attenuates the secondary energy failure phase by suppressing glutamate excitotoxicity and apoptosis

TH targets the secondary injury phase (6–72 hours after hypoxia), reducing glutamate excitotoxicity, free radical generation, inflammation, and apoptosis.

Question 54: Retinopathy of prematurity (ROP) development is primarily driven by which pathophysiological mechanism?

Systemic hypertension causing retinal artery damage
Direct light toxicity to the retina
Hyperoxia causing cessation of retinal vascularization followed by hypoxia-driven neovascularization (Correct answer)
Vitamin A deficiency impairing photoreceptor development

Correct answer: Hyperoxia causing cessation of retinal vascularization followed by hypoxia-driven neovascularization

Hyperoxia stops normal retinal vessel growth; when oxygen is reduced, VEGF-driven pathological neovascularization occurs, which can cause retinal detachment.

Question 55: When administering prostaglandin E1 (alprostadil) to a neonate with ductal-dependent congenital heart disease, which adverse effect requires immediate readiness?

Bradycardia
Hyperglycemia
Apnea (Correct answer)
Hypertension

Correct answer: Apnea

Apnea is the most critical adverse effect of prostaglandin E1 infusion in neonates, requiring intubation readiness at the bedside.

Question 56: A 28-week gestational age neonate develops candidemia. Which antifungal agent is the drug of choice, particularly given the risk of concurrent CNS involvement?

Voriconazole
Micafungin
Amphotericin B (deoxycholate or liposomal formulation) (Correct answer)
Oral fluconazole

Correct answer: Amphotericin B (deoxycholate or liposomal formulation)

Amphotericin B is the preferred first-line treatment for invasive candidiasis in neonates because of its superior CNS penetration, which is critical since neonatal candidemia frequently involves meningitis.

Question 57: A 6-week-old infant presents with apnea, bradycardia, and poor perfusion. Heart rate is 40 bpm. After initiating CPR, which vascular access is the fastest to establish?

Peripheral IV in antecubital vein
Intraosseous access (IO) (Correct answer)
Umbilical venous catheter
Central venous catheter

Correct answer: Intraosseous access (IO)

Intraosseous access is the fastest vascular access in pediatric emergencies when peripheral IV fails, allowing immediate delivery of resuscitative medications.

Question 58: Late-onset sepsis in premature neonates is most commonly caused by which organism?

Streptococcus agalactiae (Group B Strep)
Listeria monocytogenes
Haemophilus influenzae
Coagulase-negative Staphylococcus (CoNS) (Correct answer)

Correct answer: Coagulase-negative Staphylococcus (CoNS)

Coagulase-negative Staphylococcus, particularly S. epidermidis, is the leading cause of late-onset sepsis in premature neonates, largely due to its ability to form biofilms on central venous catheters.

Question 59: During an outbreak of necrotizing enterocolitis (NEC) in a NICU, which pathogen is most commonly implicated in epidemic NEC clusters?

Cronobacter sakazakii (Correct answer)
Staphylococcus aureus
Rotavirus
Group B Streptococcus

Correct answer: Cronobacter sakazakii

Cronobacter sakazakii (formerly Enterobacter sakazakii) is strongly associated with epidemic NEC outbreaks in premature neonates, often traced to contaminated powdered infant formula.

Question 60: Which electrolyte abnormality is most common in preterm neonates in the first 24–48 hours of life?

Hypokalemia
Hypermagnesemia
Hypocalcemia
Hypernatremia (Correct answer)

Correct answer: Hypernatremia

Hypernatremia (or hyperchloremia) occurs in the first days of life due to high insensible water losses from immature skin and inadequate free water intake.

Question 61: Hyperbilirubinemia in neonates becomes concerning when bilirubin crosses the blood-brain barrier, causing which condition?

Kernicterus (bilirubin encephalopathy) (Correct answer)
Polycythemia
Hydrops fetalis
Neonatal lupus

Correct answer: Kernicterus (bilirubin encephalopathy)

Kernicterus results from unconjugated bilirubin depositing in basal ganglia and brainstem nuclei, causing acute bilirubin encephalopathy with potential permanent neurological damage.

Question 62: Which healthcare worker behavior is the most modifiable and impactful risk factor for MRSA transmission in the NICU?

Speaking without a mask near the isolette
Using the same blood pressure cuff on multiple patients
Inadequate hand hygiene between patient contacts (Correct answer)
Use of shared stethoscopes without disinfection

Correct answer: Inadequate hand hygiene between patient contacts

Inadequate hand hygiene between patient contacts is the most significant and most preventable risk factor for MRSA and other pathogen transmission in any healthcare environment.

Question 63: A 3-year-old child has an anaphylactic reaction at a peanut-free facility. What is the first-line treatment?

Methylprednisolone IV
Diphenhydramine IV
Albuterol nebulization
Epinephrine IM (0.01 mg/kg) into the anterolateral thigh (Correct answer)

Correct answer: Epinephrine IM (0.01 mg/kg) into the anterolateral thigh

Intramuscular epinephrine 0.01 mg/kg (max 0.5 mg) into the anterolateral thigh is the first-line treatment for anaphylaxis in children — antihistamines and steroids are adjuncts.

Question 64: During neonatal transport, a 27-week premature neonate becomes increasingly tachycardic and pale. Blood glucose is 22 mg/dL. What is the first intervention?

Administer sodium bicarbonate 2 mEq/kg
IV dextrose 10% at 2 mL/kg bolus (Correct answer)
IV epinephrine 0.01 mg/kg
Increase ventilator rate by 5 breaths/min

Correct answer: IV dextrose 10% at 2 mL/kg bolus

Symptomatic hypoglycemia in a neonate is treated with a D10W minibolus of 2 mL/kg IV, providing approximately 200 mg/kg glucose to rapidly restore euglycemia.

Question 65: A 9-year-old child aspirates while eating gummy bears with her twin sister. She was laying on her left side at the time of aspiration. The child is in no apparent distress. The neonatal/pediatric specialist quickly suctions the child. What should the specialist do next?

Roll the patient to the right side for postural drainage (Correct answer)
Sit the patient up and perform the Heimlich maneuver
Order a chest x-ray
Perform back blows

Correct answer: Roll the patient to the right side for postural drainage

Since the child aspirated while lying on her left side, the aspirated material is most likely in the left lung. To facilitate postural drainage and help clear the airway, the specialist should roll the patient to the opposite (right) side. This position uses gravity to help move secretions from the affected left lung segment into larger airways for removal.

Question 66: A 2-month-old presents with sudden cardiac arrest and is found to have hypertrophic cardiomyopathy (HCM). Which medication is CONTRAINDICATED in management?

Dopamine in high doses (>10 mcg/kg/min) (Correct answer)
Verapamil

Question 68: Patent ductus arteriosus (PDA) in a preterm neonate creates a left-to-right shunt. Which organ is MOST at risk from increased blood flow?

Lungs (Correct answer)
Liver
Brain
Kidney

Correct answer: Lungs

Left-to-right PDA shunting increases pulmonary blood flow, causing pulmonary edema, worsening respiratory failure, and increased risk of BPD.

Question 69: Which of the following should the neonatal/pediatric specialist recommend for an 8 year-old child with cerebral atrophy and poor cognitive skills in order to promote bronchial hygiene while delivering a bronchodilator?

intrapulmonary percussive ventilation (Correct answer)
external chest wall percussive device
intermittent positive pressure breathing
in-insufflator

Correct answer: intrapulmonary percussive ventilation

Intrapulmonary percussive ventilation (IPV) delivers small, rapid bursts of air into the lungs, creating oscillations that help mobilize secretions and improve bronchial hygiene. For a child with cerebral atrophy and poor cognitive skills, IPV can be more effective and less dependent on patient cooperation than other methods, while also facilitating bronchodilator delivery directly into the airways.

Question 70: A mother is found to have Group B Streptococcus (GBS) bacteriuria during the current pregnancy. What is the appropriate intrapartum management to protect the neonate?

Intrapartum antibiotic prophylaxis (IAP) with penicillin G administered to the mother (Correct answer)
Oral amoxicillin for 7 days postpartum given to the neonate
No prophylaxis is needed unless the neonate shows infection signs
Immediate neonatal prophylaxis with ampicillin regardless of maternal treatment status

Correct answer: Intrapartum antibiotic prophylaxis (IAP) with penicillin G administered to the mother

GBS bacteriuria at any colony count is an indication for intrapartum antibiotic prophylaxis with penicillin G because it signifies heavy GBS colonization and significant risk of neonatal early-onset GBS disease.

Cyanosis
Decreased breath sounds
Bradycardia
Bounding peripheral pulses (Correct answer)

Correct answer: Bounding peripheral pulses

Patent ductus arteriosus (PDA) involves the failure of a fetal blood vessel to close after birth, leading to shunting of blood from the aorta to the pulmonary artery. This results in increased systemic blood flow during diastole, causing a wide pulse pressure and characteristically bounding peripheral pulses. This clinical finding is a key indicator of PDA.

Question 104: Which vaccination is specifically recommended for all healthcare workers in the NICU as part of a 'cocooning' strategy to protect neonates from pertussis?

Hepatitis B vaccine series
Tdap (tetanus, diphtheria, acellular pertussis) booster (Correct answer)
MMR (measles, mumps, rubella) vaccine
Annual influenza vaccine

Correct answer: Tdap (tetanus, diphtheria, acellular pertussis) booster

Tdap vaccination for all NICU healthcare workers creates a protective immune 'cocoon' around neonates who are too young to have completed their pertussis vaccination series.

Question 105: Which condition is the most common cause of air leak syndrome in mechanically ventilated neonates?

RDS with high PIP ventilation (Correct answer)
Pulmonary hypoplasia
Congenital diaphragmatic hernia
Meconium aspiration syndrome

Correct answer: RDS with high PIP ventilation

Inhaled nitric oxide (iNO) therapy requires a specialized Nitric Oxide Delivery System to precisely administer the gas to neonates. This system ensures accurate dosing, mixing with oxygen, and continuous monitoring of iNO levels, which is crucial for treating conditions like persistent pulmonary hypertension. Other equipment like oxygen blenders or nebulizers are not designed for the specific and precise delivery of nitric oxide.

Question 111: Which approach best describes the standard for surrogate decision-making for neonates?

Substituted judgment — what would the neonate choose if they could speak
Legal guardian is always appointed by the court for neonates
Best interest standard — parents decide what is in the neonate's best interest (Correct answer)
Physician determines best interest without parental input

Correct answer: Best interest standard — parents decide what is in the neonate's best interest

Neonatal decision-making uses the 'best interest standard' where parents, guided by medical teams, determine what course of action would best serve the neonate's welfare.

Question 112: When using a mechanical ventilator in neonatal care, what is the typical initial setting for positive end-expiratory pressure (PEEP)?

6-8 cm H2O
1-2 cm H2O
3-5 cm H2O (Correct answer)
9-10 cm H2O

Correct answer: 3-5 cm H2O

In neonatal mechanical ventilation, positive end-expiratory pressure (PEEP) is applied to keep the alveoli open at the end of exhalation, improving oxygenation and preventing atelectasis. An initial PEEP setting of 3-5 cm H2O is commonly used to provide adequate alveolar recruitment and maintain lung volume without causing excessive lung distension or compromising venous return.

Question 113: Which approach is central to family-centered care in the NICU?

Treating parents as partners in care and decision-making (Correct answer)
Limiting parental visits to preserve quiet healing time
Restricting information to reduce parental anxiety
Delegating family communication to social workers only

100 bpm
80 bpm
40 bpm
60 bpm (Correct answer)

Correct answer: 60 bpm

NRP guidelines specify initiating chest compressions when HR remains <60 bpm after 30 seconds of effective PPV with 100% oxygen.

Question 115: Which condition causes hypocalcemia in neonates born to mothers with hyperparathyroidism?

Maternal PTH crosses the placenta and suppresses neonatal PTH
Maternal calcium is consumed by the fetus in utero
Neonatal renal failure impairs calcium reabsorption
Maternal hypercalcemia suppresses fetal parathyroid gland development (Correct answer)

Correct answer: Maternal hypercalcemia suppresses fetal parathyroid gland development

Maternal hypercalcemia chronically suppresses fetal parathyroid gland development; after birth, the neonate cannot maintain calcium without maternal supply, causing severe hypocalcemia.

Question 116: A breastfeeding mother of a NICU infant is struggling with milk supply. Which intervention has the strongest evidence for increasing supply?

Formula supplementation to reduce demand on the mother
Frequent pumping (8+ times per day) combined with skin-to-skin contact (Correct answer)
Domperidone as first-line pharmacologic therapy
Restricting fluid intake to concentrate milk

Correct answer: Frequent pumping (8+ times per day) combined with skin-to-skin contact

Frequent pumping mimicking an infant's feeding pattern (8 or more times per day), combined with kangaroo care, is the most effective evidence-based strategy for establishing and maintaining milk supply.

Question 117: A pediatric patient in status asthmaticus fails initial bronchodilator therapy. Which IV medication is administered next?

Ketamine
Terbutaline IV
Magnesium sulfate (Correct answer)
Aminophylline

Correct answer: Magnesium sulfate

IV magnesium sulfate is recommended as second-line therapy for pediatric status asthmaticus not responding to initial bronchodilators, due to its bronchodilatory effect.

Question 118: A pediatric patient with traumatic brain injury has a GCS of 7. What is the initial target PaCO2?

25–30 mmHg (aggressive hyperventilation)
50–60 mmHg
35–40 mmHg (normocapnia) (Correct answer)
45–50 mmHg (permissive hypercapnia)

Correct answer: 35–40 mmHg (normocapnia)

Normocapnia (PaCO2 35–40 mmHg) is targeted in pediatric TBI to avoid cerebral vasoconstriction from hypocapnia; prophylactic hyperventilation is no longer recommended.

Question 119: What is the correct IV dose of adenosine for a pediatric patient with supraventricular tachycardia (SVT)?

0.05 mg/kg rapid IV push
1 mg/kg rapid IV push
0.1 mg/kg rapid IV push (Correct answer)
0.3 mg/kg rapid IV push

Correct answer: 0.1 mg/kg rapid IV push

Adenosine 0.1 mg/kg (max 6 mg first dose) is given as a rapid IV push for pediatric SVT, followed by a saline flush to ensure rapid delivery to the heart.

Question 120: To reduce the risk of hypoglycemia in a full-term newborn weighing 2,900 grams, what should the nurse do?

Maintain the infant's temperature above 97.7°F. (Correct answer)
Feed the infant glucose water every 3 hours until breastfeeding well.
Encourage the mother to breastfeed every 4 hours.
Assess blood glucose levels every 3 hours for the first twelve hours.

Correct answer: Maintain the infant's temperature above 97.7°F.

Hypothermia in newborns significantly increases their metabolic rate and oxygen consumption, which rapidly depletes their limited glucose stores. Maintaining a stable core body temperature above 97.7°F (36.5°C) minimizes this metabolic stress and helps conserve glucose, thereby directly reducing the risk of hypoglycemia. Thermal regulation is crucial for glucose homeostasis.

Question 121: Which opiate analgesic is MOST commonly used for procedural pain management in neonates due to its predictable pharmacokinetics?

Morphine
Meperidine
Hydromorphone
Fentanyl (Correct answer)

Question 122: Which finding on chest X-ray is classic for neonatal respiratory distress syndrome (RDS)?

Hyperinflation with flattened diaphragms
Lobar consolidation
Pleural effusions
Diffuse ground-glass opacity with air bronchograms (Correct answer)

Correct answer: Diffuse ground-glass opacity with air bronchograms

Neonatal RDS classically shows diffuse ground-glass opacification with air bronchograms due to surfactant deficiency causing widespread alveolar atelectasis.

Question 123: A preterm neonate on CPAP at 6 cmH2O has increasing work of breathing and FiO2 requirement >40%. What is the next appropriate intervention?

Administer inhaled surfactant via LISA/MIST technique (Correct answer)
Increase CPAP to 10 cmH2O
Switch to high-flow nasal cannula
Immediately intubate and place on conventional ventilation

Correct answer: Administer inhaled surfactant via LISA/MIST technique

LISA (Less Invasive Surfactant Administration) or MIST (Minimally Invasive Surfactant Therapy) allows surfactant delivery without intubation in neonates failing CPAP.

Question 124: What is the primary purpose of a high-frequency oscillatory ventilator (HFOV) in neonatal and pediatric care?

To provide continuous positive airway pressure (CPAP)
To deliver high tidal volumes at low frequencies
To administer aerosolized medications
To improve oxygenation and ventilation in patients with severe lung disease (Correct answer)

Correct answer: To improve oxygenation and ventilation in patients with severe lung disease

High-frequency oscillatory ventilation (HFOV) is a specialized mode of mechanical ventilation used for neonates and pediatric patients with severe lung disease, such as severe RDS or ARDS. It delivers very small tidal volumes at extremely high frequencies, aiming to maintain lung recruitment and optimize gas exchange while minimizing ventilator-induced lung injury, thereby improving oxygenation and ventilation.

Question 125: What is the significance of a pulmonary interstitial emphysema (PIE) finding on chest X-ray in a ventilated preterm neonate?

It confirms surfactant therapy success
It is a benign finding requiring no intervention
It indicates adequate lung recruitment
It represents air dissecting into lung interstitium, a risk factor for tension pneumothorax (Correct answer)

Correct answer: It represents air dissecting into lung interstitium, a risk factor for tension pneumothorax

PIE represents air trapped in the pulmonary interstitium and perivascular sheaths, and can progress to pneumothorax, pneumomediastinum, or pneumopericardium.

Question 126: Which is the most common cause of cardiac arrest in the pediatric population outside of the neonatal period?

Electrolyte imbalances
Congenital heart defects
Primary ventricular fibrillation
Respiratory failure leading to hypoxic cardiac arrest (Correct answer)

Correct answer: Respiratory failure leading to hypoxic cardiac arrest

Unlike adults, pediatric cardiac arrest is predominantly caused by respiratory failure (asphyxia) rather than primary cardiac arrhythmia, making airway management the priority.

Chlorhexidine skin antisepsis at insertion site
Hand hygiene before catheter insertion and maintenance
Routine scheduled catheter replacement every 7 days (Correct answer)

Correct answer: Routine scheduled catheter replacement every 7 days

Routine scheduled catheter replacement is not recommended and may increase infection risk by creating additional opportunities for contamination; removal should be based on clinical indication only.

Question 129: What is the correct energy dose for the FIRST defibrillation attempt in a pediatric patient with ventricular fibrillation?

2 J/kg (Correct answer)
10 J/kg
4 J/kg
0.5 J/kg

Correct answer: 2 J/kg

PALS recommends an initial defibrillation dose of 2 J/kg for pediatric VF/pulseless VT, with subsequent shocks at 4 J/kg.

Question 130: A preterm neonate requires indomethacin for PDA closure. Which lab value must be monitored most closely?

Serum creatinine (Correct answer)
Hemoglobin
Serum sodium
Serum calcium

Correct answer: Serum creatinine

Indomethacin reduces renal prostaglandin synthesis, causing decreased GFR and elevated serum creatinine; renal function must be monitored closely.

Question 131: A term neonate has a capillary blood gas drawn from the heel. The results are as follows: pH 7.28, PCO2 52 mm Hg, HCO3 24 mEq/L. How should these results be interpreted?

Respiratory acidosis (Correct answer)
Metabolic acidosis
Normal
Mixed acidosis

Correct answer: Respiratory acidosis

The blood gas results show a pH of 7.28 (acidic) and an elevated PCO2 of 52 mm Hg, while the HCO3 is within the normal range. An elevated PCO2 indicates that the lungs are not effectively eliminating carbon dioxide, leading to a buildup of carbonic acid in the blood. Therefore, the primary problem is respiratory acidosis.

Neonatal/Pediatric Specialty (NPS) Examination
