HCO3 = 25 mmol/L (ref range 22-26 mEq/L)
PaO2 = 90 mmHg (ref range 75-100 mmHg)
a. Respiratory alkalosis
b. Normal ABG
c. Respiratory Acidosis
d. Partially compensated respiratory acidosis - THE ANSWRB. Normal ABG
Interpret these ABG results pH
= 7.28 (ref range 7.35-7.45)
PaCO2 = 60 mmHg (ref range 35-45 mmHg)
HCO3 = 22 mmol/L (ref range 22-26 mEq/L)
PaO2 = 78 mmHg (ref range 75-100 mmHg)
a. Metabolic alkalosis
b. Respiratory alkalosis
c. Respiratory acidosis
d. Metabolic acidosis - THE ANSWRc. Respiratory Acidosis
Patient situations associated with respiratory alkalosis include which condition?
,a. Sedation
b. Anxiety
c. Pulmonary edema
d. Neuromuscular blockage - THE ANSWRb. Anxiety
Which of the following is the priority nursing assessment in the care of a patient who has a
tracheostomy?
a. Respiratory rate and oxygen saturation.
b. Electrolyte levels and daily weights.
c. Pain assessment and assessment of mobility.
d. Assessment of speech and swallowing. - THE ANSWRa. Respiratory rate and oxygen
saturation
Respiration compensation involves the excretion or retention of which gas or substance?
a. CO2
b. H2O
c. K+
d. HCO3 - THE ANSWRa. CO2
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. - THE ANSWRc. 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. - THE ANSWRa. 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. - THE ANSWRc. Splint the rib cage when coughing.
The client has a severe head injury begins to hypoventilate. The nurse could anticipate which
ABG result?
