The nurse administers oxygen to a patient who has lost a moderate amount of blood following a motor vehicle accident. What is the primary reason for this intervention?
 
  1. ease the work of breathing for the patient
  2. compensate for the reduction in circulating oxygen
  3. provide comfort during assessment
  4. prevent shock from developing

Question 2

While preparing a patient for a bronchoscopy, the nurse ensures the suction equipment is available. Why is the nurse taking this precaution?
 
  1. There is a high risk of a reaction to medications used for sedation.
  2. Laryngospasm and respiratory distress could follow this test.
  3. Suction equipment should always be available.
  4. Pulmonary embolus is a complication following this test.

Answer to Question 1

Correct Answer: 2
As blood volume is lost, hemoglobin is lost. Oxygen is carried from the respiratory system to the cells by hemoglobin in the blood. Breathing might be easier, the patient might be more comfortable, and the risk of shock might be decreased through the oxygen administration, but these are additional benefits, and not the primary reason.

Answer to Question 2

Correct Answer: 2
Anesthetics given for the procedure might suppress the cough and gag reflexes. Secretions might be difficult for the patient to expectorate without assistance. If the secretions are not removed, respiratory distress can occur. The suction equipment would be used to remove the secretions, so it must be ready to go before the procedure even starts. A potential reaction to medications used for anesthesia or sedation would be assessed prior to the test. Suction equipment does not always have to be available for every diagnostic test. Pulmonary emboli development is not a commonly anticipated complication of a bronchoscopy.
