During the assessment of a patient's voice sounds, the nurse hears increased and clear sounds over the patient's right lower lobe. This finding is consistent with which health problem?
 
  1. emphysema
  2. lobar pneumonia
  3. asthma
  4. pleural effusion

Question 2

During pulmonary function tests, a patient is found to have approximately 500 mL of air moving in and out of the lungs during normal quiet breathing. The nurse realizes that this finding is considered the:
 
  1. tidal volume.
  2. expiratory reserve volume.
  3. residual volume.
  4. vital capacity.

Answer to Question 1

Correct Answer: 2
Voice sounds are increased and clearer over lobar pneumonia. Voice sounds are decreased or absent over areas of atelectasis, asthma, pleural effusion, and pneumothorax.

Answer to Question 2

Correct Answer: 1
Tidal volume (TV) is the amount of air (approximately 500 mL) moved in and out of the lungs with each normal, quiet breath. Inspiratory reserve volume (IRV) is the amount of air (approximately 2100 to 3100 mL) that can be inhaled forcibly over the tidal volume. Expiratory reserve volume (ERV) is the approximately 1000 mL of air that can be forced out over the tidal volume. The residual volume is the volume of air (approximately 1100 mL) that remains in the lungs after a forced expiration. Vital capacity (VC) refers to the sum of TV + IRV + ERV and is approximately 4500 mL in the healthy patient.
