MULTIPLE CHOICE

1. A patient just had his tracheostomy suctioned. Which change in the patient’s status would the nurse expect to see immediately after suctioning was completed?

ANS:  A

Suctioning significantly increases the heart rate for 4 to 5 minutes following the procedure. The respiratory rate varies normally, and there would be a variation from before the procedure when the patient needed suctioning and afterward. There is a significant decrease in the oxygen saturation for 4 to 5 minutes following the procedure. The patient’s respiratory effort would be easier after suctioning.

3. A patient with a major chest injury was originally alert and oriented after recovery from surgery but is now becoming apprehensive and dizzy. What action should be taken by the nurse immediately?

ANS:  B

Apprehension, dizziness, anxiety, a decreased ability to concentrate, and fatigue are indicators of impaired gas exchange. The nurse needs to assess the patient’s cardiopulmonary status, including vital signs and pulse oximeter. The healthcare provider will be notified if there is a need for additional intervention. Elevating the head of the bed may be helpful, but the patient needs to be assessed immediately. Pain medication could decrease the respiratory system, which is already showing an adverse status.

4. An older adult patient with a nasal cannula and extension tubing is able to get out of bed independently. What teaching by the nurse is indicated for this patient?

ANS:  C

This older patient is at risk for tripping and falling over the extension tubing. Slippers need to be worn when ambulating, but the risk for tripping and falling is priority. The patient should keep the oxygen on as long as the extension tubing reaches. The oxygen rate is considered medication and should not be changed by the patient.

5. An oxygen cylinder is turned on, and the gauge registers in the green range. What action should the nurse take at this time?

ANS:  A

The gauge should register in the green range, which indicates that there is an adequate amount of oxygen in the cylinder. The respiratory therapy department oversees oxygen administration, but there is no reason to contact them because there is no problem. The cylinder of oxygen being used is fine and does not need to be replaced at this time. The oxygen rate is considered medication and should not be changed.
