Correct Answer is B
Explanation
A. Document the presence of borborygmi.Loud, high-pitched, and almost continuous gurgling sounds can indicate borborygmi.However, the nurse should not immediately document without fully assessing all four quadrants to ensure a comprehensive evaluation of bowel sounds.
B. Auscultate the remaining quadrants.A complete assessment of bowel sounds involves auscultating all four quadrants to determine if the sounds are generalized, localized, or absent in other areas. This provides a more accurate assessment of the client’s gastrointestinal function.
C. Elevate the head of the client’s bed immediately.The client’s position does not typically affect bowel sounds, and elevating the head of the bed is unnecessary unless the client has difficulty breathing or other non-gastrointestinal concerns.
D. Use the bell of the stethoscope to auscultate again.Using the bell, which is intended for low-pitched sounds like bruits or heart murmurs, would not provide any additional relevant information.
Correct Answer is B
Explanation
Choice A rationale
Placing the stethoscope over the clavicle is not the correct starting point for systematically auscultating anterior breath sounds.
Choice B rationale
The nurse should begin by placing the stethoscope over the lung apex, which is located just above the clavicle. This ensures a systematic approach to auscultation.
Choice C rationale
The aortic site is not relevant for auscultating breath sounds; it is used for cardiac auscultation.
Choice D rationale
Placing the stethoscope over the sternum is not the correct starting point for auscultating breath sounds.
