What is the first medication to give for wheezing due to an allergic reaction?
- A. Albuterol via nebulizer
- B. Cromolyn 20 mg via nebulizer
- C. Methylprednisolone 100 mg IV
- D. Aminophylline 500 mg IV
Correct Answer: A
Rationale: Albuterol is the first-line medication for treating wheezing due to an allergic reaction. Albuterol is a short-acting beta-agonist that helps relieve bronchospasm quickly. Cromolyn is more commonly used for the prevention of asthma symptoms rather than for acute treatment. Methylprednisolone and aminophylline are not the first-line medications for acute wheezing due to an allergic reaction.

What is the correct response when a patient receiving an enema reports abdominal cramping?
- A. Lower the height of the enema container
- B. Stop the enema procedure
- C. Remove the enema tubing
- D. Continue the enema at a slower rate
Correct Answer: A
Rationale: The correct response when a patient receiving an enema reports abdominal cramping is to lower the height of the enema container. Lowering the height reduces the flow rate, which can help relieve cramping. Stopping the procedure (choice B) may not be necessary if adjusting the height resolves the issue. Removing the enema tubing (choice C) is not the initial step to take when addressing abdominal cramping during an enema. Continuing the enema at a slower rate (choice D) might not be as effective as lowering the height of the container to alleviate cramping.
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.
What are the expected symptoms in a patient with a thrombotic stroke?
- A. Gradual loss of function on one side of the body
- B. Sudden loss of consciousness
- C. Severe headache and confusion
- D. Loss of sensation in the affected limb
Correct Answer: A
Rationale: A thrombotic stroke typically presents with a gradual loss of function on one side of the body. This gradual onset distinguishes it from a hemorrhagic stroke, which often manifests with sudden and severe symptoms like loss of consciousness (choice B), severe headache and confusion (choice C), or loss of sensation in the affected limb (choice D). Therefore, choices B, C, and D are not typically associated with thrombotic strokes.
What ECG changes are seen with hyperkalemia?
- A. Flattened T waves
- B. Elevated ST segments
- C. Prominent U waves
- D. Widened QRS complex
Correct Answer: A
Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.
What intervention is needed for continuous bubbling in the chest tube water seal chamber?
- A. Tighten the connections of the chest tube system
- B. Clamp the chest tube
- C. Replace the chest tube system
- D. Continue monitoring the chest tube
Correct Answer: A
Rationale: The correct intervention for continuous bubbling in the chest tube water seal chamber is to tighten the connections of the chest tube system. Continuous bubbling indicates an air leak in the system, and tightening the connections can help resolve this issue. Clamping the chest tube (Choice B) is not appropriate and can lead to complications by obstructing the drainage system. Similarly, replacing the entire chest tube system (Choice C) may not be necessary if the issue can be resolved by tightening the connections. Continuing to monitor the chest tube (Choice D) without taking action to address the continuous bubbling may delay necessary interventions to prevent complications.
