Mechanical Ventilation Final with NBRC
Questions
closed suction catheters may be more appropriate than using open suctioning because
of -
\they reduce the risk of infections
the procedure of instilling normal saline into the ET before suctioning is known to -
\increase an elderly pts sensation of dyspnea
silent aspiration and VAP can occur with cuffed Et's as a result of -
\injury to the mucosa during insertion and manipulation of the tube following insertion,
interference with the normal cough reflex, and aspiration of contaminated secretions
that pool above the ET cuff
what is true regarding the special ET that provides continuous aspiration of subglottic
secretions? -
\a pressure of 20 mmHg is applied continuously to the suction lumen
a 15 yop with sever acute asthma is being mechanically ventilated. what method will
deliver the largest quantity of a beta agonist to the respiratory tract? -
\SVN
when delivering a medication by MDI to a ventilated pt the best placement for the device
in the ventilator circuit is -
\less than 30 cm from the Y connector on the inspriatory side of the circuit with spacer
what statement is not true when using an externally powered SVN placed in the
ventilator circuit? -
\the HME doesnt have to be removed from the circuit when using an SVN
the use of atropine in pts who will be having fiberoptic bronchoscopy is for the purpose
of -
\reducing respiratory rate and Ve
during fiberoptic bronchoscopy of mechanically ventilated pts the RT can anticipate
what types of changes in ventilator fucntion -
\increase in peak pressure
postural drainage positions recommended for mechanically ventilated pts include -
\seated
, a pt on mechanical ventilation is suctioned for large amounts of foul smelling green
sputum. the pt has a temp of 39C and an elevated WBC count. the most likely cause of
this problem is -
\pseudomonas infection
pt centered mechanical ventilation involves -
\asking the pt about his or her level of comfort and dyspnea when making ventilator
changes
what must be performed during pt transport to reduce the risk of complications -
\provide adequate oxygenation and ventilation, maintain acceptable hemodynamic
stability, and monitor the pts cardiopulmonary status
a 25 yow is recovering from serve pneumonia and has been receiving ventilatory
support for 2 days. current FiO2 is 60% and the pts PaO2 on this setting is 200 mmHg.
what changes in FiO2 would achieve a target PaO2 of 80 mmHg? -
\0.25
CPAP can only be used with pts who has -
\spontaneous breathing
a PEEP study is being performed on a pt when the PEEP is increased form 10 to 15,
CO decreases from 4 to 2. what would be the next most appropriate step? -
\decreased PEEP to 10
during mechanical ventilation with VC CMV the PEEP is 10 and PIP is 34. the PEEP is
increased to 15 and PIP rises to 40. the rise PIP indicates -
\a normal occurrence when PEEP is increased
a 38 yom with ARDS is undergoing mechanical ventilation. the results of ABG are pH
7.38, PaCO2 42, PaO2 55. the ventilator settings are FiO2 0.9, f 10 bpm, Vt 550, and
PEEP 5. based on this information, what midge be changed to improve the pts
oxygenation status -
\PEEP
recent research suggests the way to establish an optimum PEEP level in a pt with
ARDS is to -
\perform a recruitment de-recruitment maneuver to establish the UIPd during deflation
assessment for optimum PEEP is being determined in a mechanically ventilated pt.
PEEP is increased from 5 to 10 to 15. Volume delivery remains constant at 450. PaO2
increases form 55 to 63 to 78. BP remains fairly constant. mixed venous PO2 goes from
27 to 36 to 30 at 15 of PEEP. based on these findings, the mot appropriate action is to -
\use a PEEP of 10
