Explanation

• The Frontal suture is correctly matched with its location between the two frontal bones.
• The Coronal suture is correctly matched with its location between the frontal and parietal bones.
• The Lambdoidal suture is correctly matched with its location between the parietal bones and the upper margin of the occipital bone.
• The Sagittal suture is correctly matched with its location between the two parietal bones.

Why Other Options Were Wrong

• Option A: This option incorrectly matches all the sutures. For example, it pairs the Frontal suture with the location 'Between frontal and parietal bone' (A-1), which actually describes the Coronal suture.
• Option C: This option incorrectly matches all the sutures. It reverses the pairings, for instance, matching the Frontal suture with the location of the Lambdoidal suture (A-4).
• Option D: This option incorrectly matches all the sutures. It scrambles the correct pairings, for example, matching the Frontal suture with the location of the Sagittal suture (A-2).

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Anatomy and identification of fetal skull sutures as background academic context rather than a clinical decision trigger.
• Assessing fetal head position and descent during labor by palpating sutures via vaginal examination is a key nursing skill in obstetrics.
• Postnatally, nurses assess fontanelles (the junctions of sutures) for signs of dehydration (sunken) or increased intracranial pressure (bulging).
• What if? If a newborn's sagittal suture fuses prematurely (craniosynostosis), the head will grow abnormally long and narrow (scaphocephaly) because growth is restricted perpendicular to the fused suture. This requires surgical intervention.

How to Approach the Question

• This is a 'Match the Following' question, which tests your recall of anatomical relationships.
• First, read both lists carefully to understand the items to be matched: List I has the names of sutures, and List II has their locations.
• Focus on one item from List I at a time. For example, start with 'A. Frontal suture' and find its correct location in List II.
• The frontal suture lies between the two frontal bones. This matches with '3' in List II. So, A-3 is one pair.
• Continue this process for B, C, and D. The coronal suture (B) is between frontal and parietal bones (1), so B-1. The lambdoidal suture (C) is between parietal and occipital bones (4), so C-4. The sagittal suture (D) is between the two parietal bones (2), so D-2.
• Finally, combine your matches (A-3, B-1, C-4, D-2) and find the option that contains this exact combination.
