Explanation

The normal respiratory rate for a newborn is between 30 and 60 breaths per minute.
Tachypnea, or rapid breathing, is clinically defined in a newborn as a sustained respiratory rate greater than 60 breaths per minute.
This is often the earliest and most sensitive sign of respiratory distress in the neonatal period, stemming from various pulmonary or systemic causes.

Option A: While a rate of 80 is severely tachypneic, the clinical threshold for defining tachypnea begins at a rate exceeding 60 breaths per minute.
Option B: This is the lower limit of the normal respiratory rate for a newborn. A sustained rate below 30 is defined as bradypnea and is also a cause for concern.
Option C: This rate falls comfortably within the normal respiratory range of 30-60 breaths per minute for a healthy, resting newborn.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition of tachypnea in newborns as background academic context rather than a clinical decision trigger.
Assessing respiratory rate is a critical nursing skill. In newborns, it's the most sensitive vital sign for detecting early respiratory compromise from conditions like Respiratory Distress Syndrome (RDS), Transient Tachypnea of the Newborn (TTN), or sepsis.
A finding of tachypnea requires immediate further assessment for other signs of distress (grunting, flaring, retractions) and prompt reporting to the healthcare provider.
What if? If a newborn's respiratory rate was 55 breaths/minute but was accompanied by nasal flaring and mild intercostal retractions, the nurse should not be reassured by the 'normal' rate. The presence of other distress signs indicates a problem, and the infant requires continuous monitoring and likely intervention, as they may be tiring and heading towards respiratory failure.

How to Approach the Question

First, identify the core of the question: it asks for the specific numerical value that defines 'tachypnea' in a 'newborn'.
This is a factual recall question. Access your knowledge of normal pediatric vital signs.
Recall the normal respiratory rate range for a newborn, which is 30-60 breaths per minute.
Understand that 'tachy-' means fast. Therefore, tachypnea is a rate above the normal range.
Evaluate the options: 30 and 40 are within the normal range. 80 is above the threshold, but 60 is the upper limit of normal.
Select the option that represents the upper limit of the normal range, as any value exceeding this is considered tachypneic.
