Explanation

For effective positive-pressure ventilation (PPV) in a newborn, the mask must create a tight seal over both the mouth and the nose.
The mask should be sized appropriately to fit from the bridge of the nose to the cleft of the chin, without putting pressure on the eyes.
Covering both the mouth and nose is essential because infants can breathe through either, and a seal over both is required to deliver air to the lungs.
Avoiding the eyes is a critical safety measure to prevent pressure-related injury to the infant's delicate ocular structures.

Option A: Covering only the mouth is incorrect because it allows air to escape through the nose, preventing effective lung inflation. Neonates are preferential nose breathers, but a seal must be made over both.
Option B: Covering the mouth and eyes, as shown in Image A, indicates the mask is too large. This is dangerous as it can cause pressure damage to the infant's eyes.
Option C: A mask that extends over the chin, as depicted in Image C, is too large. This prevents a proper seal, leading to significant air leaks and ineffective ventilation.

Visual 2: Illustration - The 'C-E' clamp technique, showing the rescuer's hand forming a 'C' over the mask and an 'E' to lift the jaw, ensuring a proper seal and open airway.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Neonatal Resuscitation and Bag-Mask Ventilation Technique as background academic context rather than a clinical decision trigger.
Proper bag-mask ventilation is the most important initial step in neonatal resuscitation for an apneic or bradycardic infant. Mastery of this skill is essential for all healthcare providers involved in deliveries.
Patient Safety: Using the wrong size mask or improper technique leads to ineffective ventilation, delaying recovery and potentially causing harm (e.g., eye injury, gastric insufflation).
What if? If the infant's chest does not rise despite correct mask placement and a good seal, the next step is to follow the MR. SOPA mnemonic, starting with repositioning the airway and suctioning if needed, before considering increasing pressure or an alternative airway.

How to Approach the Question

First, identify the core clinical skill being tested: neonatal bag-mask ventilation.
Recall the fundamental principles of airway management: a patent airway and an effective seal are necessary for ventilation.
Analyze each option based on these principles. Consider why each placement would be effective or ineffective.
Option 1 (mouth only): Ineffective, as air will escape through the nose.
Option 2 (mouth and eyes): Dangerous and ineffective, as the mask is too large.
Option 3 (over the chin): Ineffective, as the mask is too large and will leak.
