The nurse is teaching a mother how to perform chest physiotherapy and postural drainage on her 3-year-old child, who has cystic fibrosis. To enable the mother to perform percussion, the nurse should instruct her to:

a. Cover the skin with a shirt or gown before percussing.
b. Strike the chest wall with a flat-hand position.
c. Percuss over the entire trunk anteriorly and posteriorly.
d. Percuss before positioning for postural drainage.

Question 2

It is important to make certain that sensory connectors and oximeters are compatible since wiring that is incompatible can cause:

a. Hyperthermia. c. Pressure necrosis.
b. Electrocution. d. Burns under sensors.

Answer to Question 1

ANS: A
For postural drainage and percussion, the child should be dressed in a light shirt to protect the skin and placed in the appropriate postural drainage positions. The chest wall is struck with a cupped-hand, not a flat-hand, position. The procedure should be done over the rib cage only. Positioning precedes the percussion.

Answer to Question 2

ANS: D
It is important to make certain that sensor connectors and oximeters are compatible. Wiring that is incompatible can generate considerable heat at the tip of the sensor, causing second- and third-degree burns under the sensor. Incompatibility would cause a local irritation or burn, not hyperthermia. A low voltage is used, which should not present risk of electrocution. Pressure necrosis can occur from the sensor being attached too tightly, but this is not a problem of incompatibility.
