A patient being mechanically ventilated suddenly develops cardiac dysrhythmias from increasingly higher PEEP. What underlying issue should the nurse suspect in this patient?
1. decreased cardiac output and acidosis
2. increased cardiac output and alkalosis
3. decreased cardiac output and renal failure
4. increased cardiac output and electrolyte disturbance
Question 2A patient is being mechanically ventilated with SIMV at a rate of 25 breaths per minute. Why should the nurse question this order?
1. The rate could be too high for this mode.
2. The patient would be more comfortable with a different mode.
3. The patient is not receiving enough sedation.
4. SIMV is always used in combination with PEEP.
Question 3A patient diagnosed with sepsis suddenly develops dyspnea, crackles, agitation, and confusion. The nurse recognizes these are symptoms of which health problem?
1. noncardiogenic pulmonary edema
2. right-sided heart failure
3. left-sided heart failure
4. constrictive pericarditis
Question 4A patient being mechanically ventilated requires increasing PEEP for worsening ARDS. The order for PEEP is now at 20 cm of H2O. The nurse will need to contact the physician immediately if the patient develops which finding?
1. lung sounds greater on one side than the other
2. lung sounds with crackles
3. diminished peripheral pulses
4. high-pressure alarm
Question 5A patient being mechanically ventilated develops hypotension after the respiratory therapist implements the most recent physician orders. The nurse suspects that which ventilator mode might be the cause?
1. PEEP
2. SIMV mode
3. assist-control mode
4. pressure-control mode
Question 6A patient has a nasal endotracheal tube. For which complications should the nurse assess this patient?
Select all that apply.
1. tracheoesophageal fistula
2. wound infection
3. pressure necrosis of nares
4. sinusitis
5. obstruction of the tube
Question 7The nurse is caring for a patient who is receiving neuromuscular blocking agents and is mechanically ventilated. When planning care for this patient, the nurse should recall that the alarms are not bypassed or turned off for what reason?
1. The patient cannot breathe.
2. The patient will experience oxygen toxicity.
3. The patient might have arrhythmias.
4. The patient may have reduced intrapleural pressure.
Question 8A patient is admitted with pulmonary edema. What is important for the nurse to assess first when completing the patient's history?
: Select all that apply.
1. cardiac history
2. pulmonary history
3. renal and cardiac history
4. pulmonary and renal history
5. recent drug use and past vaccination record
