NURS 1010 Quiz 5 Questions with
Accurate Answers Graded A+.
Discontinuous, high-pitched, short popping sounds heard during inspiration that are not cleared
by coughing - Answer crackles
Slow breathing, a decreased but regular rate, less than 10 per minute - Answer bradypnea
An increased level of carbon dioxide in the blood; the normal stimulus that causes breathing -
Answer hypercapnia
What causes oxygen deficiency in the body tissues - Answer hypoxia
The predominant sound heard when percussing over healthy lung tissue - Answer resonance
Rapid shallow breathing, rate more than 24 per minute - Answer tachypnea
High-pitched, musical sounds that occur mainly in expiration - Answer Wheezes
Difficulty in breathing when supine - Answer orthopnea
Palpable vibration, increased with lobar pneumonia - Answer fremitus
Occurs in subcutaneous emphysema, characterized by a coarse, crackling sensation palpable
over the skin surface - Answer crepitus
Allergic hypersensitivity to certain inhaled allergens; characterized by bronchospasm and
inflammation of the airways, edema in the walls of bronchioles, and secretion of highly viscous
mucus - Answer asthma
Decreased level of oxygen in the blood - Answer hypoxemia
which part of the brain mediates respirations - Answer the brainstem - pons and medulla
surfactant - Answer lipid substance needed for sustained inflation of the air sacs
, effects of aging on the lungs/thorax - Answer - costal cartilage becomes calcified; thus the
thorax is less mobile
- respiratory muscle strength declines
- decrease in elastic properties in the lungs, making them less distend to keep and lessening
their tendency to collapse and recoil
- increase in small airway closure, which causes a decreased vital capacity (the maximum
amount of air that a person can expel from the lungs after first filling the lung to maximum) and
an increased residual volume (the amount of air remaining in the lungs even after the most
forceful expiration
- gradual loss of intra-alveolar septa and alveoli, therefore less surface area for gas exchange
- lung bases become less ventilated as a result of closing off airways, increasing risk for dyspnea
with exertion beyond usual workload
- increased risk for postoperative atelectasis and infection from a decreased ability to cough, a
loss of protective airway reflexes, and increased secretions
sedentary or bedridden people are at risk for - Answer respiratory dysfunction
crepitus - Answer coarse, crackling sensation occurring in subcutaneous emphysema when
air escapes from the lung and enters subcutaneous tissue
resonance - Answer a low pitched, clear, hollow sound heard in healthy lung tissue
abnormal lung sounds - Answer - hyperresonance is lower pitched, booming sound when
too much air is present such as in emphysema or pneumothorax
- a dull note (soft, muffled thud) signals abnormal density in the lungs, as with pneumonia,
pleural effusion, atelectasis, or tumor
stridor - Answer strained, high-pitched sound heard on inspiration caused by an upper
airway obstruction
Muscles used in respiration - Answer diaphragm, external intercostals, internal intercostals,
scalenes
