1. What are the expected signs of compartment syndrome?

A. Unrelieved pain, pallor, and pulselessness
B. Fever, swelling, and redness
C. Muscle cramps and weakness
D. Redness and itching

Correct answer: A

Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. Compartment syndrome is characterized by increased pressure within a muscle compartment, leading to inadequate blood supply. This results in severe pain that is unrelieved by rest or medication, pallor due to compromised blood flow, and pulselessness as a late sign of severe ischemia. Choices B, C, and D are incorrect. Fever, swelling, and redness are not typical signs of compartment syndrome. Muscle cramps and weakness may occur due to other conditions, but they are not primary indicators of compartment syndrome. Redness and itching are also not commonly associated with compartment syndrome.

2. What ECG changes are expected in hypokalemia?

A. Flattened T waves on ECG
B. Prominent U waves on ECG
C. Widened QRS complexes on ECG
D. ST elevation on ECG

Correct answer: A

Rationale: In hypokalemia, flattened T waves are a common ECG finding due to the decreased extracellular potassium affecting repolarization. Prominent U waves are typically seen in hypokalemia as well, but flattened T waves are the more specific and early ECG change. Widened QRS complexes are associated with hyperkalemia, not hypokalemia. ST elevation is often seen in conditions like myocardial infarction, pericarditis, or early repolarization syndrome, not specifically in hypokalemia.

3. What should be done when continuous bubbling is observed in the chest tube water seal chamber?

A. Tighten the connections of the chest tube system
B. Replace the chest tube system
C. Clamp the chest tube
D. Continue to monitor the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the appropriate action is to tighten the connections of the chest tube system. This may resolve an air leak that is causing the continuous bubbling. Option B, replacing the chest tube system, is not the initial step to take and is considered more invasive. Clamping the chest tube (option C) can lead to complications and should not be done unless instructed by a healthcare provider. Continuing to monitor the chest tube (option D) without taking any corrective action may delay necessary interventions.

4. What does continuous bubbling in the water seal chamber of a chest tube indicate?

A. An air leak
B. A blocked chest tube
C. Normal chest tube function
D. Continuous drainage from the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak in the system. This occurs when air is entering the system through a leak, preventing the lung from fully re-expanding. Choice B, a blocked chest tube, is incorrect as a blocked tube would result in a lack of drainage rather than continuous bubbling. Choice C, normal chest tube function, is incorrect as continuous bubbling signifies an issue. Choice D, continuous drainage from the chest tube, is incorrect as bubbling in the water seal chamber specifically indicates an air leak, not just the presence of drainage.

5. What is the first medication to administer for a patient experiencing wheezing due to an allergic reaction?

A. Albuterol 3 ml via nebulizer
B. Cromolyn 20 mg via nebulizer
C. Methylprednisolone 100 mg IV
D. Aminophylline 500 mg IV

Correct answer: A

Rationale: The correct answer is A, Albuterol 3 ml via nebulizer. Albuterol is the first-line medication for wheezing due to its rapid bronchodilatory effects. Choice B, Cromolyn, is used more for preventing allergic reactions rather than acute relief of wheezing. Choice C, Methylprednisolone, is a steroid used for its anti-inflammatory effects and is not the initial choice for acute relief of wheezing. Choice D, Aminophylline, is a bronchodilator but is not the first-line treatment for wheezing due to allergic reactions.
