The instructor is teaching a class on basic assessment skills. Which of the following statements is true regarding the stethoscope and its use?

  • A. Slope of the earpieces should point forward toward the examiner's nose.
  • B. It blocks out extraneous room noise but does not magnify sound.
  • C. The tubing length should be 14 to 18 inches to prevent sound distortion.
  • D. Both fit and quality of the stethoscope are important.
Correct Answer: B

Rationale: The stethoscope does not magnify sound but effectively blocks out extraneous room noises. The correct orientation of the earpieces is with the slope pointing forward toward the examiner's nose, not posteriorly. The tubing length of a stethoscope should ideally be between 14 to 18 inches (36 to 46 cm) to avoid sound distortion. Using tubing longer than this range can distort sound. Both the fit and quality of the stethoscope are crucial for accurate auscultation and assessment, highlighting their significance in clinical practice. Therefore, the correct answer is that the stethoscope blocks out extraneous room noise but does not magnify sound.
