Correct Answer: auscultation.
the correct answer to the question "a 6-year-old is wheezing. the nurse uses the diaphragm of the stethoscope to listen to the child's chest. which of the following techniques of physical assessment is the nurse using?" is auscultation.
auscultation is a clinical technique used in the physical examination of patients to listen to the sounds produced within the body, primarily in the heart or lungs. it is a critical component in the assessment of respiratory conditions, such as asthma, where wheezing may be present. wheezing is a high-pitched whistling sound associated with difficulty in breathing, typically resulting from narrowed airways or obstruction.
in the practice of auscultation, a stethoscope is used, which has two parts that can be used for listening: the diaphragm and the bell. the diaphragm, a larger, flat part of the stethoscope, is effective for picking up high-pitched sounds such as normal breath sounds, bowel sounds, and wheezing. therefore, when the nurse uses the diaphragm to listen to a wheezing child, she is effectively applying the appropriate tool to detect these high-frequency respiratory sounds.
on the other hand, the bell of the stethoscope, which is smaller and concave, is used primarily to listen to lower-pitched sounds. this part is particularly useful for catching sounds like heart murmurs or bruits. it is not typically used for assessing high-pitched lung sounds like wheezing.
the technique of auscultation requires skill and experience as the nurse must be able to distinguish between normal and abnormal sounds. the ability to effectively discern and interpret these sounds can significantly influence the diagnosis and subsequent treatment plans for the patient. in the case of a child presenting with wheezing, identifying the characteristics of the wheeze can help in determining whether it is caused by a simple bronchial obstruction, asthma, or other more complex respiratory issues.
thus, in the scenario described, auscultation is the correct technique being utilized by the nurse. this method not only aids in confirming the presence of wheezing but also potentially provides insights into the severity and nature of the airway obstruction, guiding further diagnostic and therapeutic interventions.
