The nurse prepares to conduct a quick evaluation of a 1-month-old infant's hearing. Which action will provide the best information?
1. Examining the child's ear canal with an otoscope
2. Using a vibrating tuning fork placed against the child's skull
3. Using tympanometry to assess the child's hearing
4. Using a noisemaker to evaluate the child's response
4
Explanation:
1. Inspection of the ear canal and membrane will not provide any information on the infant's hearing ability.
2. In a school-age child, this will test bone conduction, but it is not appropriate for an infant.
3. Tympanometry is a tool to evaluate the movement of the tympanic membrane. Although related to sound transmission, it is not the best response.
4. This is a quick, simple evaluation of the child's ability to hear sounds. The child's response can be a stopping of activity, widening of the eyes, or turning toward the sound.

The patient has a bronchodilator and an inhaled steroid scheduled for the same time. What teaching should the nurse provide to the patient about administering these medications?
a. Inhale the bronchodilator, wait 20 to 30 seconds, then inhale the steroid. b. Inhale the bronchodilator, wait 2 to 5 minutes, then inhale the steroid. c.

During inspiration, muscular contraction of the diaphragm causes air to move into the lung. The mechanism that drives air movement during inspiration results in a(n):
a. decrease in intra-alveolar pressure and shortening of the rib cage. b. decrease in the size of the thorax and alveolar expansion. c. increase in the size of the thorax and decrease in intrapleural pressure. d. increase in atmospheric pressure and intrapleural pressure.
