Which of the following statements is true regarding tension pneumothorax?
- A.
Trachea is shifted toward affected lung and breath sounds are absent on that side as well.
- B.
Trachea is shifted toward normal lung and needle decompression is indicated between the 2nd and 3rd intercostal space anteriorly.
- C.
Trachea is shifted toward normal lung and breath sounds are absent on that side as well.
- D.
Trachea is shifted toward normal lung and needle decompression is indicated between the 4th and 5th intercostal space anteriorly.
Correct Answer
B. Trachea is shifted toward normal lung and needle decompression is indicated between the 2nd and 3rd intercostal space anteriorly.Explanation
Tension pneumothorax is a life-threatening condition where air accumulates in the pleural space, causing the lung to collapse and putting pressure on the heart and other structures in the chest. In tension pneumothorax, the trachea is shifted away from the affected lung and towards the normal lung. This is because the increased pressure in the affected side pushes the trachea away. Additionally, breath sounds are absent on the affected side due to the collapsed lung. Needle decompression is the immediate treatment for tension pneumothorax and is performed between the 2nd and 3rd intercostal space anteriorly to release the trapped air.Rate this question:

Which of the following occurs as a result of indirect lung injury?
- A.
Pneumonia, fat emboli, near drowning
- B.
Pulmonary contusion, aspiration of gastric contents
- C.
Sepsis, cardiopulmonary bypass, drug overdose
- D.
Inhalation injury, pneumonia, pulmonary contusion
Correct Answer
C. Sepsis, cardiopulmonary bypass, drug overdoseExplanation
Indirect lung injury refers to damage to the lungs that is not caused directly by trauma or a physical injury. Sepsis, cardiopulmonary bypass, and drug overdose can all lead to indirect lung injury. Sepsis is a severe infection that can cause inflammation and damage to the lungs. Cardiopulmonary bypass is a procedure used during heart surgery that can cause lung inflammation and injury. Drug overdose, especially with certain substances like opioids, can lead to respiratory depression and lung damage. Therefore, sepsis, cardiopulmonary bypass, and drug overdose can all result in indirect lung injury.Rate this question:

For a pneumothorax that communicates with the atmospheric air , what is the immediate treatment?
- A.
Occlusive dressing
- B.
Needle decompression
- C.
Chest tube
- D.
Suture
Correct Answer
A. Occlusive dressingExplanation
An occlusive dressing is the immediate treatment for a pneumothorax that communicates with the atmospheric air. This is because an occlusive dressing creates an airtight seal over the wound, preventing further air from entering the pleural space. By sealing the wound, the occlusive dressing helps to restore normal lung function and prevent the collapse of the lung. Needle decompression and chest tube insertion may be necessary in more severe cases, but the immediate treatment is to apply an occlusive dressing. Suture is not appropriate for treating a pneumothorax.Rate this question:

Avoid administration of mannitol in these patients (select two).
- A.
CHF
- B.
Renal failure
- C.
Liver failure
- D.
Diabetic
Correct Answer(s)
A. CHF
B. Renal failureExplanation
Mannitol is a diuretic medication commonly used to decrease intracranial pressure and reduce intraocular pressure. However, it should be avoided in patients with congestive heart failure (CHF) and renal failure because it can exacerbate fluid overload and worsen their condition. CHF patients already have impaired cardiac function and may not tolerate the additional fluid volume, while renal failure patients have compromised kidney function and may not be able to adequately excrete the excess fluid. Therefore, administration of mannitol in these patients can lead to fluid retention and potentially worsen their cardiac and renal function.Rate this question:

- E.
Propofol
- F.
Dexmedetomide
- G.
Halothane
Correct Answer(s)
A. Ketamine
C. N20Explanation
Ketamine and N20 are the two anesthetic agents that increase CMRO2. Ketamine is a dissociative anesthetic that increases cerebral metabolic rate of oxygen consumption (CMRO2) by stimulating the release of catecholamines. N20, also known as nitrous oxide, increases CMRO2 by increasing cerebral blood flow. Both of these agents have the ability to enhance brain activity and metabolism, leading to increased CMRO2.Rate this question:

How much CSF should be drained in increments with ongoing assessment?
- A.
10-15ml
- B.
5-10ml
- C.
5-10L
- D.
1-5ml
Correct Answer
B. 5-10mlExplanation
CSF (Cerebrospinal fluid) should be drained in increments of 5-10ml with ongoing assessment. This is because draining too much CSF at once can lead to complications such as low pressure headaches or spinal cord injury. By draining smaller amounts and continuously assessing the patient's condition, any adverse effects can be detected and managed promptly. This approach ensures a safer and more effective CSF drainage procedure.Rate this question:

________________________ is the most sensitive method of monitoring for VAE.
- A.
TEE
- B.
Precordial
- C.
ETCO2 >0.5%
- D.
CVP
Correct Answer
A. TEEExplanation
Transesophageal echocardiography (TEE) is the most sensitive method of monitoring for venous air embolism (VAE). TEE involves inserting a probe into the esophagus to obtain detailed images of the heart and blood vessels. This technique allows for real-time visualization of the heart and can detect even small amounts of air in the circulation. It is considered the gold standard for diagnosing VAE and is particularly useful during surgical procedures where air embolism is a potential risk, such as cardiac surgeries. TEE provides immediate feedback, allowing prompt intervention to prevent further complications.Rate this question:

Which is the correct order of the fastest to slowest method of reducing ICP?
- A.
Steroids>mannitol>lasix>hyperventilation
- B.
Hyperventilation>lasix>mannitol>steroids
- C.
Lasix>mannitol>hyperventilation>steroids
- D.
Mannitol >lasix>hyperventilation>steroids
Correct Answer
D. Mannitol >lasix>hyperventilation>steroidsExplanation
The correct order of the fastest to slowest method of reducing ICP is mannitol > lasix > hyperventilation > steroids. Mannitol is a potent osmotic diuretic that rapidly reduces intracranial pressure by drawing water out of the brain tissue. Lasix is a loop diuretic that also helps to decrease fluid volume in the brain. Hyperventilation lowers ICP by causing vasoconstriction and reducing cerebral blood flow. Steroids, such as dexamethasone, are typically used to treat brain swelling but have a slower onset of action compared to the other methods mentioned.Rate this question:

What should you avoid in patients with elevated ICP?
- A.
Coughing
- B.
Straining
- C.
Vasodilators
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
Patients with elevated intracranial pressure (ICP) should avoid coughing, straining, and vasodilators. Coughing and straining can increase ICP by causing increased intrathoracic and intraabdominal pressure, which can lead to increased cerebral blood volume and subsequently increased ICP. Vasodilators can also worsen elevated ICP by causing cerebral vasodilation, leading to increased cerebral blood flow and increased pressure within the skull. Therefore, it is important to avoid all of these factors in patients with elevated ICP to prevent further complications.Rate this question:

If a patient is given 1-2mg of edrophonium and muscle weakness gets worse, the patient is having a cholinergic crisis and atropine should be given. If the patient has improvement of symptoms, it is a myasthenic crisis. This test is called the Tensilon test.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the Tensilon test is indeed used to differentiate between a myasthenic crisis and a cholinergic crisis. In a myasthenic crisis, the patient's muscle weakness improves after administration of edrophonium, whereas in a cholinergic crisis, the muscle weakness worsens. Atropine is given in a cholinergic crisis to counteract the excessive cholinergic stimulation. Therefore, the correct answer is true.Rate this question:

When the patient is in the sitting position, you can estimate that the MAP at the level of the heart is ________ mmHg higher than the MAP at the level of the tragus of the ear if the distance is 20cm.
- A.
5
- B.
10
- C.
15
- D.

Correct Answer
C. 15Explanation
When a patient is in the sitting position, the distance between the level of the heart and the level of the tragus of the ear is approximately 20cm. As per the question, we need to estimate the difference in Mean Arterial Pressure (MAP) at these two levels. MAP is a measure of the average blood pressure in the arteries during a cardiac cycle. In the sitting position, due to the effect of gravity, blood pressure is higher at the level of the heart compared to the tragus of the ear. Therefore, we can estimate that the MAP at the level of the heart is 15mmHg higher than the MAP at the level of the tragus of the ear.Rate this question:

What are the two most common things that anesthesia providers do that inhibit hypoxic pulmonary vasoconstriction?
- A.
Keep fluid less than 2ml/kg/hr
- B.
Too much tidal volume
- C.
Too much peep
- D.
Keep PIP less than 40
Correct Answer(s)
B. Too much tidal volume
C. Too much peepExplanation
Anesthesia providers inhibit hypoxic pulmonary vasoconstriction by performing two common actions: providing too much tidal volume and applying too much positive end-expiratory pressure (PEEP). Too much tidal volume refers to delivering excessive amounts of air during each breath, which can lead to overdistension of the lungs and hinder hypoxic pulmonary vasoconstriction. Similarly, excessive PEEP, which is the pressure maintained in the airways at the end of expiration, can also interfere with this physiological response by increasing lung volume and impairing the redirection of blood flow to well-ventilated areas.Rate this question:

Due to catecholamine depletion, which INDIRECT acting drug should be avoided in Parkinson's patients?
Correct Answer(s)
EphedrineExplanation
Ephedrine is an indirect acting drug that stimulates the release of catecholamines, such as dopamine, norepinephrine, and epinephrine. In Parkinson's disease, there is a depletion of dopamine, which leads to motor symptoms. Therefore, using a drug like ephedrine that further depletes catecholamines would worsen the symptoms of Parkinson's disease. Hence, ephedrine should be avoided in Parkinson's patients.Rate this question:

Which drug should be avoided in patients with Duchenne's muscular dystrophy due to exaggerated K+ release?
- A.
Non-depolarizing NMBA
- B.
Depolarizing NMBA
- C.
Sevoflurane
- D.
Etomidate
Correct Answer
B. Depolarizing NMBAExplanation
Depolarizing neuromuscular blocking agents (NMBA) should be avoided in patients with Duchenne's muscular dystrophy due to exaggerated potassium (K+) release. Depolarizing NMBA, such as succinylcholine, cause a prolonged depolarization of the muscle membrane, leading to an excessive release of K+ from the muscle cells. In patients with Duchenne's muscular dystrophy, who already have a defect in the dystrophin protein that helps maintain the integrity of muscle cells, this exaggerated K+ release can lead to life-threatening hyperkalemia and cardiac arrhythmias. Therefore, it is important to avoid depolarizing NMBA in these patients to prevent this complication.Rate this question:

Cor Pulmonale is usually caused by:
- A.
COPD
- B.
Brochiectasis
- C.
Cystic Fibrosis
- D.
Sarcoidosis
Correct Answer
A. COPDExplanation
Cor Pulmonale is a condition characterized by right-sided heart failure due to lung disease. The most common cause of Cor Pulmonale is chronic obstructive pulmonary disease (COPD). COPD is a progressive lung disease that obstructs airflow and causes difficulty in breathing. The long-term exposure to irritants, such as cigarette smoke, is the primary cause of COPD. The damage to the lungs in COPD leads to increased pulmonary artery pressure, which can eventually result in right-sided heart failure and Cor Pulmonale. Therefore, COPD is the most likely cause of Cor Pulmonale among the given options.Rate this question:

Cystic Fibrosis causes dehydrated, viscous secretions. For this reason, ____________ drugs should be avoided and inhalational agents should be humidified.
- A.
Non-depolarizing
- B.
Gaba agonist
- C.
Anticholinergic
- D.
Beta blocking
Correct Answer
C. AnticholinergicExplanation
Cystic Fibrosis causes dehydrated, viscous secretions, which can lead to airway obstruction and difficulty in clearing mucus. Anticholinergic drugs can help in reducing the viscosity of secretions and promoting airway clearance by blocking the action of acetylcholine, which is responsible for increasing mucus production. On the other hand, non-depolarizing, GABA agonist, and beta-blocking drugs do not directly address the issue of dehydrated secretions and may not be as effective in improving airway clearance. Therefore, anticholinergic drugs are preferred in the management of Cystic Fibrosis.Rate this question:
