This patient appeared to be showing signs and symptoms of a stroke, and then the diagnostic assessment and diagnostic tools began to show that he may be having a cardiac event. Why would the presence of a cardiac event lead to the symptoms described above for this patient? (A) This patient is likely experiencing a stroke as the primary problem and there may have been a portion of the brain becoming hypoxic and reducing the heart rate (B) As per the 12-lead ECG, the patient appears to be having an Inferior Myocardial Infarction, leading there to be a reduction in perfusion of oxygenated blood to the brain and in turn causing the stroke like symptoms (C) With the given history of the patient, the high cholesterol may have caused an increased build-up in the arteries and lead to a small piece detaching and forming an obstruction within an arteriole in the brain (D) In many cardiac instances, the demand of the heart for oxygenated blood is not being met, in turn it will cause the chemoreceptors to react and decrease heart rate as well as reduce blood pressure
(B) As per the 12-lead ECG, the patient appears to be having an Inferior Myocardial Infarction, leading there to be a reduction in perfusion of oxygenated blood to the brain and in turn causing the stroke like symptoms
140
What is atelecasis?
A complete or partial collapse of the entire lung or area (lobe) of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid
141
The right lung is larger than the left and has 3 main sections; the superior, middle, and inferior lobe. Which lobe is the left lung missing?
Middle lobe as that space is taken up by the heart.
142
1. Respiratory control is primarily governed by the ____ | 2. Controlled in response to increased or decreased O2 or CO2 levels?
1. Brainstem | 2. CO2 levels determine rate of respiration
143
1. What is emphysema? | 2. How will patients present?
1. Significant destruction of the alveolar septa (walls) causing the collapse of the bronchioles and decreases gas exchange. Leads to increased air flow obstruction and overinflation of air sacs 2. “Pink Puffers” due to their thin, anxious, alert, dyspneic, tachypneic and hyperventilation presentation Pursed lips on expiration is common as it increase airway pressure which splints the airway No current treatment other than lung transplant
144
1. What is bronchitis? | 2. How do patients present?
1. Is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. People who have bronchitis often cough up thickened mucus, which can be discolored 2. “Blue Bloaters” because of the central cyanosis noted in these patients due to shunting occurring in lung, lowering O2 saturation Usually larger person, cyanosis present, chronic cough, often productive sputum Emphysema people will be thin while bronchitis people will look bloated
145
1. What is pneumonia? | 2. Signs and symptoms?
1. Infection of the lungs leading to inflammation of bronchioles and alveoli. 2. S/S = SOB, fever, chills, pleuritic chest pain, brown/green sputum, cough
146
Change in pain upon deep inspiration and on palpation is most likely non-cardiac
Ischemia chest pain is constant and will not get better over time. Intervention in the hospital is the only thing that will make it better. ASA just helps it from getting worse.

Options: Cheyne-Stokes, Kussmaul, Biots 1. Seen in DKA commonly, also metabolic acidosis characterized by rapid deep laboured breathing 2.
