Week 9 Quiz

Question 1

Which is true of visualization on x-ray?

Answer 1

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)

Question 2

Which is true about a CT-scan?

Answer 2

Multiple x-rays give better detailed view

Question 3

What is the V/Q scan best at detecting?

Answer 3

Pulmonary Embolism (PE)

Question 4

True or False: MRI gives the best detail, avoids radiation and is the least expensive imaging available.

Answer 4

False

MRI gives the best detail, avoids radiation and is MOST expensive imaging

Question 5

When viewing the x-ray using ABCDEFG, which of the following is not true?

Answer 5

F stands for frontal view

Question 6

How many posterior ribs should be showing in an x-ray to ensure a good view of the chest and lungs?

Answer 6

9-10

Seeing 9 or more ribs ensures the inhalation has enough volume to visualize the most structures

Question 7

Which of the following is a normal ABG?

Answer 7

pH -7.4
CO2 - 40
pO2 - 85
HCO3- = 25

Question 8

Which of the following statements is true?

Answer 8

Anemia and perfusion of the capillaries affect cellular oxygen levels

60 to 80mmHg is mild
40 to 60mmHg is moderate hypoxemia

Question 9

Name the 3 problems ABGs help assess and treat

Answer 9

Acid-base balance
Alveolar ventilation
Oxygenation

Question 10

Acid - base issue associated with COPD

Answer 10

Respiratory Acidosis

Question 11

Acid-base issue associated with pulmonary embolism

Answer 11

Respiratory Alkalosis

Question 12

Acid - base issue associated with Renal Failure

Answer 12

Metabolic acidosis

Question 13

Acid-base issue associated with vomiting

Answer 13

Metabolic Alkalosis

Question 14

Which of the following is true regarding ventilator settings?

Answer 14

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

Question 15

What do ABGs assess?

Answer 15

pH
PaCO2
PaO2

Question 16

If pH and paCO2 are normal and paO2 is low, what ventilator settings are changed to increase O2?

Answer 16

FiO2 then PEEP

Question 17

Which of the following is true regarding ventilator settings?

Answer 17

ACPC sets the pressure for every breath

Question 18

Name the settings that can adjusted on a ventilator

Answer 18

Pressure
Volume
FiO2
Respiratory rate
PEEP

Question 19

What is the role of PEEP positive end expiratory pressure?

Answer 19

To provide minimum pressure so alveoli do not collapse

Question 20

Which of the following are normal respiration rate and minute ventilation settings on a ventilator?

Answer 20

10-12bpm, 4-6 L

Question 21

True or False: Spontaneous ventilator settings control volume, pressure and respiratory rate

Answer 21

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

Question 22

When pt is on a ventilator, the FiO2 is adjusted to attain the oxygen level goal of

Answer 22

60 mmHg or 90%

Question 23

Why does increasing RR help decrease paCO2?

Answer 23

With every breath we blow off some CO2, Hypoventilation allows accumulation of CO2 in the blood, hyperventilation decreases CO2 in bloodstream

Question 24

What is the difference between CPAP and PEEP?

Answer 24

Facemask vs. vent

Question 25

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.

Answer 25

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
