Which assessments and interventions should the nurse consider when performing tracheal suctioning?
- A. Closely assessing the patient before, during, and after the procedure
- B. Hyperoxygenating the patient before and after suctioning
- C. Limiting the application of suction to 20 to 30 seconds
- D. Monitoring the pulse to detect effects of hypoxia and stimulation of the vagus nerve
- E. Using an appropriate suction pressure (80 to 150 mm Hg)
- F. Inserting the suction catheter no further than 1 cm past the length of the tracheal or endotracheal tube
Correct Answer: A,B,D,E,F
Rationale: Close assessment of the patient before, during, and after the procedure is necessary to identify complications such as hypoxia, infection, tracheal tissue damage, dysrhythmias, and atelectasis. The nurse should hyperoxygenate the patient before and after suctioning and limit the application of suction to 10 to 20 seconds. In addition, monitor the patient's pulse frequently to detect potential effects of hypoxia and stimulation of the vagus nerve. Using an appropriate suction pressure (80 to 150 mm Hg) will help prevent atelectasis caused by excessive negative pressure. Research suggests that insertion of the suction catheter should be limited to a predetermined length (no further than 1 cm past the length of the tracheal or endotracheal tube) to avoid tracheal mucosal damage.

A nurse in the emergency department is caring for a patient who was brought in by fire rescue due to a heroin overdose. The nurse notes the patient is not breathing. What action will the nurse take immediately?
- A. Tilt the patient's head forward.
- B. Begin ventilation using a manual resuscitation bag (Ambu bag).
- C. Place the mask tightly over the patient's nose and mouth.
- D. Pull the patient's jaw backward.
- E. Compress the bag twice the normal respiratory rate for the patient.
- F. Recommend that a sputum culture for cytology is obtained.
Correct Answer: B,C
Rationale: The priority is to establish ventilation using the manual resuscitation bag to provide emergency or rescue breathing. The nurse tilts the head back, pulls the jaw forward, and positions the mask tightly over the patient's nose and mouth. The bag is compressed at a rate that approximates normal respiratory rate (e.g., 12 to 20 breaths/min in adults). Sputum for cytology is done primarily to detect cells that may be malignant, determine organisms causing infection, and identify blood or pus in the sputum. Note that the bag, with the mask removed, also fits easily over tracheostomy and endotracheal tubes.
A nurse is teaching a patient how to use a metered-dose inhaler for asthma. Which comments from the patient assure the nurse that the teaching has been effective?
- A. I'll be careful not to shake the canister before using it.
- B. It's important to hold the canister upside down when using it.
- C. I have to remember to inhale the medication through my nose.
- D. I will continue to inhale when the cold propellant is in my throat.
- E. I won't inhale more than one spray with one breath.
- F. I will activate the device while continuing to inhale.
Correct Answer: D,E,F
Rationale: Common mistakes that patients make when using MDIs include failing to shake the canister, holding the inhaler upside down, inhaling through the nose rather than the mouth, inhaling too rapidly, stopping the inhalation when the cold propellant is felt in the throat, failing to hold their breath after inhalation, inhaling two sprays with one breath, and not activating the device while inhaling.
A nurse is caring for a patient who has a pleural chest tube attached to a disposable chest drainage system. Which nursing actions are indicated for this patient?
- A. Avoiding turning the patient to prevent disconnections in the tubing
- B. Maintaining an occlusive dressing on the site
- C. Assessing the patient for signs of respiratory distress
- D. Keeping the chest drainage device at the level of the patient's thorax
- E. Ensuring there are no dependent loops or kinks in the tubing
- F. Observing for bubbles indicating air leak in the water seal chamber
Correct Answer: B,C,E,F
Rationale: The chest drainage collection device must be positioned below the tube's insertion site. Maintaining an occlusive dressing helps prevent air leak; assess for crepitus around the chest tube site indicating air leak. Avoid dependent loops or kinks in the tubing, which could impede drainage. Assess for bubbling in the water seal, maintaining the water level at the 2-cm mark. When a chest tube becomes separated from the drainage device, the nurse should submerge the tube's end in water, creating a temporary water seal and allowing air to escape until a new drainage unit can be attached.
A nurse plans to suction a patient's endotracheal tube using the open suction technique. Which intervention is appropriate for this technique?
- A. Using a suction catheter that is the diameter of the endotracheal tube
- B. Maintaining the patient in the supine position
- C. Administering oxygen prior to suctioning
- D. Changing the inline suction device every 24 hours
Correct Answer: C
Rationale: To prevent hypoxemia, prior to endotracheal suctioning, the nurse provides 100% oxygen for a minimum of 30 seconds. This is referred to as hyperoxygenation. The nurse limits the application of suction to no more than 10 to 15 seconds. The external diameter of the suction catheter should not exceed half of the internal diameter of the endotracheal tube. An inline suction device is considered a closed, self-contained system used for a 'closed technique' for suction; these are changed every 24 hours.
A nurse is caring for a patient admitted for an acute asthma exacerbation. The patient reports extreme dyspnea, stating, 'Turn up the oxygen, I'm not getting enough air.' Which actions would the nurse take first?
- A. Suction the airway.
- B. Assess the pulse oximetry reading.
- C. Obtain a peak flow meter reading.
- D. Assess for cyanosis of the lips.
Correct Answer: B
Rationale: Using the nursing process, the nurse first assesses the oxygen saturation via pulse oximetry before changing the oxygen flow rate. Suctioning is provided to remove respiratory secretions; the nurse would note adventitious breath sounds or phlegm with cough indicating a need for suction. A peak flow meter is used to assess the point of highest flow during forced expiration. It is routinely used for patients with moderate or severe asthma to measure the severity of the disease and degree of disease management. While cyanosis of the lips is a late sign of hypoxemia, the nurse can quickly begin to alleviate or lessen dyspnea by simply repositioning the patient.
