Q

During a Thoracoscopy, the doctor states that he is going to begin the procedure by inserting the thoracoscope directly through the patient’s sternum to look inside the patient’s chest space. Specifically, inside of the lungs.
What is wrong with this situation?

A

-A Thoracoscopy observes the chest space outside of the lungs
-A Thoracoscope is inserted through the back, below the shoulder blade and in-between the ribs.

Q

True or False:
A Thoracentesis is the insertion of a large-bore needle through the lower shoulder blade, in-between the lungs to collect Pleural fluid for the purpose of diagnostic studies, or medicine insertion.

A

False
Thoracentesis IS the collection of Pleural fluid for studies, or medication insertion, but its point-of-entry is through the chest wall directly into the pleural space.

17
Q

Forced expiratory volume in first second (FEV1)
refers to what?

A

The amount of air forcefully exhaled in the 1st second of FVC

18
Q

What isthe Forced expiratory volume in first second (FEV1) test responsible for assessing?

A

It grades the severity of an airway obstruction.

19
Q

Peak expiratory flow rate (PEFR) refers to what?

A

It refers to the maximum flow rate of air during forced expiration.

20
Q

If a patient is forcefully expiring air as hard as they can, this amount of air that they can exhale is called what?

A

Forced Vital Capacity

21
Q

If a nurse wants to measure the maximum expiratory flow rate of a patients Forced Vital Capacity, what would be the test that the nurse does?

A

PEFR, Peak Expiratory Flow Rate

22
Q

What does an “ABG” test stand for?

A

ABG stands for Arterial Blood Gas test.

23
Q

What does a ABG test do?

A

Measures the amount of oxygen and carbon dioxide in your blood.

24
Q

A nurse needs to check the levels of blood oxygen and blood CO2 in her patients arteries. What test would the nurse use to check for these values?

A

An ABG test. Arterial Blood Gas test.

25
Q

What is a normal pH level? Normal PaCO2 level? Normal PaO2 level?

A

pH: 7.35-7.45
PaCO2: 45-35mmHg
PaO2: 75-100mmHg

26
Q

A patient’s ABG tests come back with the following results:
Ph 7.39
paCO2: 41mmHg
PaO2: 95mmHg
What do these lab values indicate?

A

The patient is showing normal lab values for an ABG test.

27
Q

The amount of O2 molecules bound to your Hemoglobin is measured by what diagnostic test?

A

Pulse Oximetry test.

28
Q

A Peak Flow Meter measures what in a patient? What is it used for identifying?

A

The strength and ability to push air out of your lungs. Often used for Asthma effect tests.

29
Q

A Green Zone range in a Peak Flow Meter test would be in what percentage range? What about Yellow? Red?

A

Green is 80-100%
Yellow is 50-80%
Red is anything below 50%

30
Q

What is the Peak Expiratory Flow Rate measurable with a Peak Flow Meter?

A

up to 600 L/min

31
Q

A patient’s HCO3- range should be how many mEq/L?

A

22-26 mEq/L

32
Q

Expectoration, and Tracheal suction are methods of Sputum studies. What is one other method of culturing Sputum?

A

A Bronchoscopy

33
Q

Inhalation of an irritating aerosol to forcefully induce expectoration is called what?

A

Sputum Induction

34
Q

What is a CXR?

A

Chest X-ray

35
Q

A Fluoroscopy involves passing what through the body over a period of time? What does this allow for?

A

It’s the Passing of x-rays through the body.
It allows for real-time videos of the movements inside of a body.

36
Q

A CT scan (Computed Tomography) is used to do what?

A

Used to Diagnose suspicious Lesions.

37
Q

If a physician notices a suspicious lesion on a patient which of these tests would he use to assess the lesion?
a.) Fluoroscopy
b.) CXR
c.) CT scan

A

c.) CT scans assess suspicious lesions

38
Q

IF a Ct scan is inconclusive, a physician might try an MRI next. An MRI test, Magnetic Resonance Imaging, assesses for what?

A

MRIs are for an in-depth diagnosis of lesions that a CT scan can’t give. It’s also for differentiating Vascular and Non-Vascular structures.

39
Q

If A nurse wants to do a test for discerning between Vascular and Non-Vascular structures in a body, which test would be done:
a.) CT scan
b.) MRI
c.) Fluoroscopy
d.) CXR

A

b.) MRI scans for in-depth analysis of lesions as well as discerning vascular and non-vascular structures.

40
Q

An Angiography done on someone would check for the health of what?

A

The health of your blood vessels and how blood is flowing through them.

41
Q

A patient shows signs of CHD (coronary heart disease) such as chest pain. The physician orders a test to assess for the patients’ blood vessel health by using a scan to see how the blood travels through his vessels. Which test would the physician use?
a.) MRI
b.) Fluoroscopy
c.) CXR
d.) Angiography
e.) Ct scan

A

d.) Angiography is used to see how blood flows through the vessels

42
Q

A V/Q scan (Ventilation Perfusion scan) tests what?

A

The Ventilation and Perfusion of the lungs.

43
Q

A radioactive gas is inhaled to outline the alveoli in what diagnostic test?
a.) CXR
b.) Angiography
c.) Lung Biopsy
d.) V/Q scan

A

d.) V/Q scan involves the patient inhaling radioactive gas to outline the alveoli

44
Q

A patient inhales radioactive dust during a V/Q scan. The reports show a very small, almost nonexistent amount of radioactive gas in the alveoli after inspiration. What would this finding suggest?

A

There is a lack of perfusion, or a lack of airflow to the lungs.

45
Q

What is perfusion in the lungs?

A

Perfusion is the flow of blood to alveolar capillaries.
