Lecture 1: Ventilators - mike klimek
A nurse is caring for a client who is receiving ventilation and develops acute respiratory distress. Which of the following actions should the nurse take first? a. Initiate bag valve mask ventilation B. Provide the client with a communication boards c. Obtain a blood sample for ABG analysis d. Document the ventilator settings
A
A nurse is caring for a client who has a tracheostomy and is receiving mechanical ventilation. When the low pressure alarm on the ventilator sounds, it indicates which of the following? A. Excessive airway secretions b. A leak within the ventilators circuitry c. Decreased lung compliance d. The client coughing or attempting to talk
B Low pressure alarm means that either tubing has come apart or the tubing detached from the client.
Nurse is caring for client who is receiving mechanical ventilation via a tracheostomy tube and has a gastrostomy tube for enteral feedings. Which pieces of information are critical to communicate to the next nurse who will be caring for the client? SATA a. Room temp b. New prescriptions c. Number of visitors d. Arterial blood gas results e. Tracheal secretion characteristics
B, D, E
Pick which order to do first. High pressure alarm goes off. A. Suction B. Empty water from tubing C. Check for kinks D. Cough, deep breathe
C B D A
A nurse is caring for a client who requires ventilators assistance with breathing following a motor vehicle crash. The nurse should suspect an injury to which of the following parts of the brain? a. Hypothalamus b. Cerebral cortex c. Brainstem d. Cerebellum
C Injury to the medulla and pons of the brain stem for a client who is experiencing difficulty with breathing. The brainstorm serves as the respiratory control center, and a neurological injury can impair this center and inhibit respiratory function
1 type of disconnection causing low pressure alarm
Disconnection from main ventilator - reconnect
Low pressure alarms are triggered by what? (Too easy to push air in)
Disconnections
Respiratory alkalosis may mean the ventilator settings are too ________
High over ventilating
Leading cause of obstruction leading to high pressure alarm
Kinks in tubing - unkink
3rd most common cause of obstruction in ventilator
Mucous membranes in airway - turn, cough, deep breathe - then suction (PRN)
Another type of disconnection causing low pressure alarm
Oxygen sensor tubing disconnection - measures FiO2 at trachea area - black wire. If pops off air goes out that hole - Plug it back in!
High pressure alarm triggered by ________________ _____ _____________
Resistance to air flow
The doctor says ween off vent in am. 6am ABGs show resp acidosis a. Follow order b. Call resp therapy c. Hold order. Call doctor d. Begin to decrease the settings
Under ventilation - means they need more o2 C
2nd cause of obstruction
Water condensing in tube - empty
