Management Questions for the RNC-NIC Exam — Practice Free

For preterm infants less than 35 weeks gestation, NRP guidelines recommend starting PPV with 21% to 30% oxygen. Titrate based on pre-ductal pulse oximetry targets. For infants 35 weeks or greater, start at 21%. Rationale: High oxygen concentrations in preemies are associated with oxidative stress and injury. Strategy: NCC often tests the 35-week cutoff for oxygen titration. Avoid the distractor of starting at 100% for all deliveries.

GIR = (Rate [mL/kg/day] x % Dextrose) / 144. Calculation: (120 x 12.5) / 144 = 10.4 mg/kg/min. For ELBW infants, the recommended starting GIR is 4-6 mg/kg/min to prevent hyperglycemia, titrating up to meet metabolic needs (max 12-14 mg/kg/min). NCC Tip: Always check if the question asks for the formula or the clinical action. High GIRs increase the risk of hepatic steatosis and increased CO2 production. Clinical Pearl: If the GIR exceeds 12-14, consider that the glucose oxidation limit has been reached, and excess glucose will be stored as fat.

iNO is indicated for term/late preterm (>34 wks) infants with hypoxic respiratory failure (HRF) when the OI is >25. The goal is to improve oxygenation and reduce the need for ECMO. Clinical Pearl: While some centers consider early initiation at an OI of 15-25 to prevent progression, 25 remains the standard NCC exam benchmark for proven benefit. Strategy: Always calculate OI (Mean Airway Pressure x FiO2 x 100 / PaO2) before answering indication questions.

AAP guidelines recommend immediate feeding followed by re-screening in 1 hour. However, current 2026 standards of care prioritize the use of 40% dextrose gel (0.5 mg/kg) applied to the buccal mucosa alongside feeding for asymptomatic infants with BG <35 mg/dL in the first 4 hours. This reduces NICU admissions and the need for IV therapy. Rationale: Dextrose gel is more effective than feeding alone and provides a rapid bridge to stable glucose levels. Exam Tip: NCC often tests the threshold for IV intervention; if gel/feeding fails or BG is <25 mg/dL in the first 4 hours, IV D10W is required.

Kangaroo Care (KC) provides significant physiologic benefits including improved thermoregulation, heart rate stability, and increased duration of quiet sleep. Crucially, KC is associated with improved neurodevelopmental outcomes, reduced stress markers (cortisol), and increased parental self-efficacy. Exam Strategy: NCC emphasizes that KC is a clinical intervention, not just bonding. Even intubated or CPAP-dependent infants should participate if hemodynamically stable. Common distractor: Increased risk of accidental extubation (False if performed with proper nursing supervision and standardized transfer protocols).
