Answer to Question 1
A
Low-pitched sonorous wheezing sounds are caused by secretions accumulating in the larger air-ways. Patients with pneumonia or chronic bronchitis often present with low wheezes (rhonchi). Coughing may help to partially clear the secretions. High-pitched wheezes result from narrowing of air passages, and a bronchodilator would be beneficial. Crackles are produced by air passing through moisture in the smaller airways; diuretics are beneficial. Proper technique for the incen-tive spirometer directs the patient to inhale through the mouthpiece, as if the patient is pretending to drink a thick milk shake.
Answer to Question 2
A, B, D, E
The safest and most effective technique when ambulating a blind patient involves allowing the patient to hold the nurse's arm, as the patient follows. The nurse should not hold the patient's arm, instruct the patient to place his hands on the nurse's shoulders, or hold the patient's hand, so these actions would require additional teaching.
