Why do alcohol and narcotics affect oxygen needs?
Why do alcohol and narcotics affect oxygen needs?
- They trigger allergic reactions that constrict airways.
- They depress the breathing center in the brain. (correct)
- They directly cause a pneumothorax.
- They act as pollutants within the respiratory system.
During suctioning of a patient's airway, what is the MOST appropriate technique to prevent tissue damage?
During suctioning of a patient's airway, what is the MOST appropriate technique to prevent tissue damage?
- Omit wearing gloves if the patient's secretions appear clear.
- Perform suctioning routinely every 2 hours, regardless of need.
- Limit each suction cycle to 10 to 15 seconds. (correct)
- Apply continuous suction while inserting the catheter.
What is the most accurate definition of hypoxia?
What is the most accurate definition of hypoxia?
- The lack of oxygen in the environmental air.
- Insufficient oxygen reaching the body's cells. (correct)
- Not enough oxygen in the blood.
- The amount of hemoglobin that contains oxygen.

Study Notes
- Alcohol and narcotics affect oxygen needs by depressing the breathing center in the brain.
- Hypoxia is defined as not enough oxygen in the cells.
- An early sign of hypoxia is restlessness.
- Orthopnea is a condition where a client can breathe deeply and comfortably only while sitting.
- Wheezing or crowing sounds are signs of altered respiratory function.
- A client's SpO2 of 98% indicates the measurement is within normal range.
- A common site for a pulse oximetry sensor is the index finger.
- The best time to collect sputum is on awakening.
- When a sputum specimen is needed, patients should rinse their mouth with clear water.
- When assisting a client with coughing and deep breathing, they should exhale through pursed lips.
- An incentive spirometer is useful for deep breathing.
- When assisting with oxygen therapy, keep the connecting tubing secure and free of kinks.
- If a client has a tracheostomy, the outer cannula must be secured in place.
- A client who has a tracheostomy can safely shave.
- If a client has a tracheostomy, the old ties are removed after the outer cannula is held in place for safety considerations.
- When suctioning, a suction cycle should be no more than 10 to 15 seconds.
- Chest tubes remove trapped air from the chest cavity.
- An Ambu bag is used to hyperventilate the lungs.
- If a patient requires mechanical ventilation, they likely have an endotracheal (ET) tube or a tracheostomy tube.
- If an alarm sounds on a ventilator, first check to see if the airway is attached to the ventilator.
- A pneumothorax is the collection of air in the pleural space.
- When chest tubes are attached to a disposable water-seal drainage system, keep the drainage system below the client's chest.
