A chest tube is inserted, and the nurse assesses continuous gentle bubbling in the suction
chamber of the patient's closed chest drainage. The nurse evaluates the finding this finding as
a. The tubing is kinked.
b. There is an air leak present.
, c. The system is functionong normally.
d. The lung has re-expanded. - correct answer ✔✔c. The system is functioning normally.
You are assessing a 22-year-old who was admitted 3 days ago with multiple rib fractures &
pulmonary contusions following a motor vehicle crash (MVC). You find the patient has shallow
respirations at a rate of 38 per minute. He says he feels "dizzy and scared". His SaO2 is 80% and
is on O2 at 4 litres by nasal promgs. Which action is most appropriate?
a. Administer morphine to reduce hyperventilation.
b. Put the patient on a non-rebreather mask at 8L.
c. Increase the flow rate of oxygen to 10L/minute and reassess in ten minutes.
d. Encourage him to splint his chest when coughing. - correct answer ✔✔a. Administer
morphine to reduce hyperventilation.
Which of the following measures would most likely be successful in reducing pleuritic chest pain
that in a patient with after a pneumonectomy?
a. Encourage shallow breathing.
b. Use incentive spirometry.
c. Splint the rib cage when coughing.
d. Encourage abdominal breathing. - correct answer ✔✔c. Splint the rib cage when coughing.
The client has a severe head injury begins to hypoventilate. The nurse could anticipate which
ABG result?
Value Normal Abnormal
pH 7.35-7.45 <7.35 Acidosis >7.45 Alkalosis
PaO2 >90mmHg 75-89mmHg <75mmHg
Mild hypoxia Severe hypoxia
