Week 9 Quiz Flashcards
Which is true of visualization on x-ray?
Fluid might collect in costophrenic angle
You should assess for tracheal deviation
Assessment of bony alignment and integrity is possible
Great vessels should be just wider than t-spine (therefore visible)
Which is true about a CT-scan?
Multiple x-rays give better detailed view
What is the V/Q scan best at detecting?
Pulmonary Embolism (PE)
True or False: MRI gives the best detail, avoids radiation and is the least expensive imaging available.
False
MRI gives the best detail, avoids radiation and is MOST expensive imaging
When viewing the x-ray using ABCDEFG, which of the following is not true?
F stands for frontal view
How many posterior ribs should be showing in an x-ray to ensure a good view of the chest and lungs?
9-10
Seeing 9 or more ribs ensures the inhalation has enough volume to visualize the most structures
Which of the following is a normal ABG?
pH -7.4
CO2 - 40
pO2 - 85
HCO3- = 25
Which of the following statements is true?
Anemia and perfusion of the capillaries affect cellular oxygen levels
60 to 80mmHg is mild
40 to 60mmHg is moderate hypoxemia
Name the 3 problems ABGs help assess and treat
Acid-base balance
Alveolar ventilation
Oxygenation
Acid - base issue associated with COPD
Respiratory Acidosis
Acid-base issue associated with pulmonary embolism
Respiratory Alkalosis
Acid - base issue associated with Renal Failure
Metabolic acidosis
Acid-base issue associated with vomiting
Metabolic Alkalosis
Which of the following is true regarding ventilator settings?
Tidal volume is variable in pressure control settings
Volume control, controls volume allowing pressure to be variable while pressure control, sets pressure and allows volume to vary
What do ABGs assess?
pH
PaCO2
PaO2
If pH and paCO2 are normal and paO2 is low, what ventilator settings are changed to increase O2?
FiO2 then PEEP
Which of the following is true regarding ventilator settings?
ACPC sets the pressure for every breath
Name the settings that can adjusted on a ventilator
Pressure
Volume
FiO2
Respiratory rate
PEEP
What is the role of PEEP positive end expiratory pressure?
To provide minimum pressure so alveoli do not collapse
Which of the following are normal respiration rate and minute ventilation settings on a ventilator?
10-12bpm, 4-6 L
True or False: Spontaneous ventilator settings control volume, pressure and respiratory rate
False
Spontaneous modes assist the patient’s normal breathing with the pressure, FiO2 and PEEP set but the patient determines the rate and volume of the breaths
When pt is on a ventilator, the FiO2 is adjusted to attain the oxygen level goal of
60 mmHg or 90%
Why does increasing RR help decrease paCO2?
With every breath we blow off some CO2, Hypoventilation allows accumulation of CO2 in the blood, hyperventilation decreases CO2 in bloodstream
What is the difference between CPAP and PEEP?
Facemask vs. vent
True or False: A patient cannot breathe on their own, and is on a volume control ventilator. If the volume (500cc) and respiratory rate (10pm) are set the same, SIMV-VC and ACVC basically do the same thing.
True
It is only when the pt attempts to breathe more frequently than the RR that the settings differ. In both settings, the pt determines the respiratory rate (in this example above 10) with the ACVC determining the volume every breath and the SIMV-VC allowing volume to be pt determined
