The nurse is preparing to assess the sinuses of an adult client using direct percussion. Which technique is the most appropriate for this assessment?
1. Using the hyperextended middle finger of the nondominant hand.
2. Using the closed fist of dominant hand.
3. Using the palm of the nondominant hand.
4. Using the fingertips of the dominant hand.
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.
