Explanation

The standard and correct procedure for measuring head circumference requires placing the measuring tape above the eyebrows and, critically, above the pinna (ears).
The option describes placing the tape 'below the pinna,' which is an incorrect technique.
This incorrect placement fails to capture the maximum occipitofrontal circumference, leading to an inaccurate and falsely small reading.
Since the question asks to identify the incorrect practice, this option is the correct answer.

Option B: This is a correct practice. The primary goal of the procedure is to measure the head at its greatest circumference (the occipitofrontal circumference) to accurately monitor brain growth.
Option C: This is a correct practice. Using a non-stretchable tape (e.g., paper, plastic, or fiberglass) is mandatory to prevent measurement errors. A tape that stretches would yield a falsely low and unreliable reading.
Option D: This is a correct practice. Ensuring the greatest possible accuracy is a fundamental principle for all anthropometric assessments to reliably monitor a child's growth and detect any deviations from the norm.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Anthropometric Measurements: Head Circumference Technique as background academic context rather than a clinical decision trigger.
Accurate head circumference measurement is a critical nursing responsibility for monitoring infant and early childhood brain growth.
Serial measurements plotted on a growth chart are essential for the early detection of serious neurological conditions like hydrocephalus (abnormally rapid growth) or microcephaly (abnormally slow growth).
What if? If a nurse consistently measures below the pinna, the recorded values will be falsely low. This could mask developing hydrocephalus or lead to an unnecessary and stressful investigation for microcephaly, highlighting the importance of correct technique.

How to Approach the Question

First, identify the keyword 'INCORRECT' in the question stem. This signals that you are looking for the option that describes a faulty procedure.
Mentally review the standard steps for measuring head circumference. Key landmarks are above the eyebrows (supraorbital ridges), above the ears (pinna), and the most prominent part of the back of the head (occiput).
Evaluate each option against this standard procedure.
Option A describes placing the tape 'below the pinna,' which directly contradicts the standard landmark of 'above the pinna.'
Options B, C, and D describe the correct goal, correct equipment, and correct guiding principle for the measurement.
Conclude that the option describing the incorrect action (A) is the correct answer to the question.
