Areas that need to be studied Chest x-ray interpretation
You did really badly!
Classify the following arterial blood gas:
pH: 7.29, PaCO2: 47 mm Hg, HCO3: 25 mEq/l, PaO2: 95 mm Hg
Your answer: Unanswered
Here the pH is below normal range along with a higher than normal PaCO2. Since bicarbonate and Oxygen are still in the normal range, this is an "Uncompensated Respiratory Acidosis with Normoxemia", which is therefore the answer.
A large difference between PIP and Pplat is most likely to be seen in which of the following disease states?
Your answer: Unanswered
One of the hallmarks of a ventilated asthmatic patient is high airway resistance. A rough measure of this resistance can be seen as the difference between Peak airway pressure and plateau airway pressure. Essentially the measurement shows us the difference in pressure with flow present and flow not present.
Immediate potential complications with percutaneous tracheostomy tube insertion include?
- Bleeding
- Pneumothorax
- Decreased LOC
- Subcutaneous emphysema
Your answer: Unanswered
Immediate complications with percutaneous tracheostomy tube insertion can include bleeding, pneumothorax & subcutaneous emphysema. Therefore, the answer is "1, 2 & 4". In most cases, your patient would be fully sedated; therefore, decreased LOC is not a potential immediate complication.
A neonate is diagnosed with Tetrology of Fallot.
All of the following characterize Tetralogy of Fallot, except?
Your answer: Unanswered
Tetralogy of Fallot is a right sided heart lesion, where right ventricular hypertrophy is prevalent, not left. Therefore, the answer here is "Left ventricular hypertrophy".
Which of the following conditions is most consistent with unilateral elevation of the left hemi-diaphragm? As pictured below.
Your answer: Unanswered
COPD & Asthmatics would more often present with a bilateral process, that would be characterized by increased air space. Look to the right side of this xray. Typically with a pneumothorax, the x-ray would present with increased airspace (hyper-lucency). Although a pleural effusion can be bilateral, in this case it is unilateral and the fluid will always appear as increased density or “white” on an x-ray.
