A nurse is performing a physical assessment of sleeping newborn. Which body area should the nurse assess last to minimize waking or distressing the infant?

Physical assessment of a sleeping newborn is performed in a systematic manner that prioritizes minimal disturbance while still obtaining accurate clinical data. Newborns are easily aroused, and excessive stimulation can interfere with completion of the assessment and affect physiologic stability. Nurses typically begin with least invasive procedures and progress to more stimulating components. Neurological and reflex assessments are among the most stimulating parts of the exam and are therefore performed last to reduce disruption. A. Assessing reflexes and neurological responses last is appropriate because these components involve stimulation such as tapping, handling, or eliciting primitive reflexes. These actions are more likely to wake or distress the newborn, so performing them at the end preserves the infant’s sleep state for less intrusive assessments. This approach supports efficient and minimally disruptive evaluation. B. Assessing the head and face is relatively non-invasive and can be done early in the assessment while the infant is still calm or asleep. Observation and gentle palpation of facial symmetry, fontanelles, and cranial shape do not typically require stimulation that would wake the newborn. Therefore, it is not the last step in the sequence. C. Abdominal assessment involves gentle inspection and light palpation, which is moderately non-stimulating when performed carefully. It can be completed while the infant is asleep without causing significant distress. It is therefore not reserved as the final step of the assessment. D. Auscultation of the chest is a non-invasive procedure that can be performed early in the assessment with minimal disturbance. Listening to heart and lung sounds requires quiet placement of the stethoscope without stimulation. Because it does not significantly arouse the infant, it is not performed last in the sequence.
