Answer to Question 1

Correct Answer: 2

Friction on either the bell or the diaphragm from coarse body hair may cause a crackling sound easily confused with abnormal breath sounds. To avoid artifact caused from friction, the nurse should wet the hair on the client's chest before auscultation. The crackling sounds may or may not be an abnormal finding; the cause of the sounds should be fully investigated before the nurse documents the finding as abnormal. Auscultation of lung sounds over the client's clothing will increase rather than decrease friction sounds. Lung sounds are high-pitched sounds, best heard with the diaphragm of the stethoscope. Friction from hair will cause abnormal crackling sounds using either the diaphragm or the bell, so switching them won't make a difference.

Answer to Question 2

Correct Answer: 4
Direct percussion is the technique of tapping the body with the fingertips of the dominant hand. It is used to assess the thorax of an infant and also to assess the sinuses of an adult client. Indirect percussion is the technique most commonly used and performed by placing the hyperextended middle finger of the nondominant hand firmly over the area to be examined and striking it with a plexor. Blunt percussion is used for assessing pain and tenderness in the gallbladder, liver, and kidneys and involves placing the palm of the nondominant hand flat against the body surface and striking the nondominant hand with the closed fist of the dominant hand. The palm of the nondominant hand is used to assess pain and tenderness of the gallbladder, liver, and kidneys in blunt percussion.
