RCP 140 Kahoots

Midterm Kahoots

QuestionAnswer
Is PaCO2 a component of the breathing pattern? NO
A normal range for tidal volume is? 7-9 ml/kg
Dyspnea is both a symptom and a sensation experienced and described only by the patient? True or False True
Normally the demand to breathe is driven by the VO2, WOB required by the task, and the persons physical condition? True or False True
The capability to breathe is governed by lung function and reserve of the arterial blood gas values? True or False False
Patients with severe cardiopulmonary disease may feel short of breath even when performing simple ADL's? True or False True
A high score on the mMRC indicates the patient has adequate cardiopulmonary function to meet normal demand? True or False False
High Lung Compliance means? Large Vt for a small pressure gradient
Diseases with high Raw are considered restrictive lung disease? true or False False
Restrictive: Lung Parenchyma (alveoli), (Volume), decrease CL, increase Raw
Obstructive: Airways (bronchi, bronchiole), (ventilation), increase CL
Lung compliance decreases______and_____ lung volumes due to changes in surface tension? low, high
When the tube radius is cut in half, flow rates remain the same as long as driving pressure is constant? True or Flase False
To maintain a constant flow rate, driving pressure must double whenever tube radius is halved? True or False False
Central Chemoreceptors are highly sensitive to changes in ____ and _____? H+ and pH
3 receptors are located in the interstitial tissues between the pulmonary capillaries and the alveoli? True or False True
What does NOT activate J receptor stimulation? Increased bronchial secretions
Classify this ABG: pH 7.53 PaCO2 56 mmHg HCO3- 43 mEq/L and PaO2 43 mm Hg. Pt. has severe COPD with CO2 retention Acute alveolar hyperventilation superimposed on chronic vent. failure, mod. hypoxemia
Classify this ABG: pH 7.28 PaCO2 105 mmHg HCO3- 41 mEq/L and PaO2 44 mm Hg. Hx. of CO2 retention Acute on chronic vent. failure w/ moderate hypoxemia
Classify this ABG: pH 7.05 PaCO2 105 mmHg HCO3- 29 mEq/L and PaO2 41 mm Hg. on room air Acute vent. failure, moderate- severe hypoxemia
Classify this ABG: pH 7.53 PaCO2 - 24mmHg HCO3- 21 mEq/L and SpO2 86% on 3 LPM, n/c Acute alveolar hyperventilation secondary to moderate hypoxemia
You suspect your patient may have a pulmonary embolism (blood clot in their lungs); what test is NOT indicated? Echocardiogram
You suspect your patient may have a pulmonary embolism (blood clot in their lungs); what tests are indicated? CTP, V/Q scan, Pulmonary angiography
What test would not be indicated for a patient that has a right sided pleural effusion? PFT
What test would be indicated for a patient that has a right sided pleural effusion? right lateral decubitus X-ray, bedside ultrasound, standard chest X-ray
The CXR of your patient shows the absence of lung tissue markings; what is NOT a possible explanation? -emphysema -pneumothorax -pneumonectomy -under exposed chest x-ray under exposed chest x-ray
Your patient had a V/Q scan; the Vent scan is normal, but the perfusion scan is normal. What might explain this? Mucus plug
A PET scan can pinpoint and provide early detection of malignant lesions within the body? True or False True
CT scans are not useful in determining precise location, size and shape of lesions? True or False False
PET scans can locate cancer cells in tissues after changes develop in the anatomical shape? True or False False
CT scans are useful in detecting lesions as small as 0.3 - 0.5 mm? True or False False
MRI scans are superior to CT scans in detecting Congenital Heart Disorders and Adenopathy of the chest wall? True or False true
Color doppler ultrasounds are useful to detect speed and direction of blood flow? True or False True

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
