The medical nurse is creating the care plan of an adult patient requiring mechanical ventilation. What nursing action is most appropriate?
- A. Keep the patient in a low Fowlers position
- B. Perform tracheostomy care at least once per day
- C. Maintain continuous bedrest
- D. Monitor cuff pressure every 8 hours
Correct Answer: D
Rationale: The cuff pressure should be monitored every 8 hours. It is important to perform tracheostomy care at least every 8 hours because of the risk of infection. The patient should be encouraged to ambulate, if possible, and a low Fowlers position is not indicated.

A patient with a severe exacerbation of COPD requires reliable and precise oxygen delivery. Which mask will the nurse expect the physician to order?
- A. Non-rebreather air mask
- B. Tracheostomy collar
- C. Venturi mask
- D. Face tent
Correct Answer: C
Rationale: The Venturi mask provides the most accurate method of oxygen delivery. Other methods of oxygen delivery include the aerosol mask, tracheostomy collar, and face tents, but these do not match the precision of a Venturi mask.
The nurse is caring for a patient who is scheduled to have a thoracotomy. When planning preoperative teaching, what information should the nurse communicate to the patient?
- A. How to milk the chest tubing
- B. How to splint the incision when coughing
- C. How to take prophylactic antibiotics correctly
- D. How to manage the need for fluid restriction
Correct Answer: B
Rationale: Prior to thoracotomy, the nurse educates the patient about how to splint the incision with the hands, a pillow, or a folded towel. The patient is not taught how to milk the chest tubing because this is performed by the nurse. Prophylactic antibiotics are not normally used and fluid restriction is not indicated following thoracotomy.
A patient in the ICU has had an endotracheal tube in place for 3 weeks. The physician has ordered that a tracheostomy tube be placed. The patients family wants to know why the endotracheal tube cannot be left in place. What would be the nurses best response?
- A. The physician may feel that mechanical ventilation will have to be used long-term
- B. Long-term use of an endotracheal tube diminishes the normal breathing reflex
- C. When an endotracheal tube is left in too long it can damage the lining of the windpipe
- D. It is much harder to breathe through an endotracheal tube than a tracheostomy
Correct Answer: C
Rationale: Endotracheal intubation may be used for no longer than 2 to 3 weeks, by which time a tracheostomy must be considered to decrease irritation of and, trauma to, the tracheal lining, to reduce the incidence of vocal cord paralysis (secondary to laryngeal nerve damage), and to decrease the work of breathing. The need for long-term ventilation would not be the primary rationale for this change in treatment. Endotracheal tubes do not diminish the breathing reflex.
While assessing the patient, the nurse observes constant bubbling in the water-seal chamber of the patients closed chest-drainage system. What should the nurse conclude?
- A. The system is functioning normally
- B. The patient has a pneumothorax
- C. The system has an air leak
- D. The chest tube is obstructed
Correct Answer: C
Rationale: Constant bubbling in the chamber often indicates an air leak and requires immediate assessment and intervention. The patient with a pneumothorax will have intermittent bubbling in the water-seal chamber. If the tube is obstructed, the nurse should notice that the fluid has stopped fluctuating in the water-seal chamber.
What would the critical care nurse recognize as a condition that may indicate a patients need to have a tracheostomy?
- A. A patient has a respiratory rate of 10 breaths per minute
- B. A patient requires permanent ventilation
- C. A patient exhibits symptoms of dyspnea
- D. A patient has respiratory acidosis
Correct Answer: B
Rationale: A tracheostomy permits long-term use of mechanical ventilation to prevent aspiration of oral and gastric secretions in the unconscious or paralyzed patient. Indications for a tracheostomy do not include a respiratory rate of 10 breaths per minute, symptoms of dyspnea, or respiratory acidosis.
