**Core Concept**
The scenario describes a newborn with signs of fetal distress, likely due to meconium aspiration syndrome, given the "pea soup" amniotic fluid. This condition requires immediate attention to establish adequate ventilation and oxygenation.

**Why the Correct Answer is Right**
The first step in resuscitating a newborn, especially one suspected of having meconium aspiration syndrome, involves clearing the airway to prevent further meconium aspiration and to facilitate effective ventilation.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it doesn't address the immediate need to clear the airway.
**Option B:** Incorrect as it might not be the first step before ensuring the airway is clear.
**Option C:** Incorrect because, although important, it is not the initial step in resuscitation when meconium is present.

**Clinical Pearl / High-Yield Fact**
In meconium-stained neonates, especially those who are depressed or apneic, the priority is to clear the airway before starting ventilation to avoid pushing meconium further into the lungs.

**Correct Answer:** D. Suctioning the airway to remove meconium.
