1. Which ECG change is associated with hyperkalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are a characteristic ECG change seen in hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac cycle, leading to T wave abnormalities. Prominent U waves are typically seen in hypokalemia. Elevated ST segments are more indicative of myocardial infarction or pericarditis. Widened QRS complexes are commonly associated with conditions like bundle branch blocks or certain toxicities.

2. What is the priority action if a patient experiences abdominal cramping during enema administration?

• A. Lower the height of the solution container
• B. Increase the flow of the enema solution
• C. Stop the procedure and remove the tubing
• D. Continue the enema at a slower rate

Correct answer: A

Rationale: During enema administration, if a patient experiences abdominal cramping, the priority action is to lower the height of the solution container. This adjustment can help relieve abdominal cramping by reducing the flow rate of the enema, making it more comfortable for the patient. Increasing the flow of the enema solution (Choice B) can exacerbate the cramping. Stopping the procedure and removing the tubing (Choice C) may be necessary in some cases of severe discomfort or complications, but adjusting the height of the solution container should be the initial response. Continuing the enema at a slower rate (Choice D) may not address the immediate need to alleviate the cramping.

3. What should a healthcare provider monitor for in a patient with hypokalemia?

• A. Monitor for muscle weakness
• B. Monitor for bradycardia
• C. Check deep tendon reflexes
• D. Monitor for hyperglycemia

Correct answer: A

Rationale: Corrected Rationale: Muscle weakness is a common symptom of hypokalemia and should be closely monitored in affected patients. Hypokalemia is a condition characterized by low potassium levels in the blood, which can lead to muscle weakness, cramps, and even paralysis. While bradycardia (slow heart rate) can be associated with severe hypokalemia, monitoring for muscle weakness is more specific to the condition. Checking deep tendon reflexes is not typically a primary monitoring parameter for hypokalemia. Monitoring for hyperglycemia is not directly related to hypokalemia, as hypokalemia is primarily associated with potassium levels in the blood.

4. What is the first medication to give to a patient with an allergic reaction causing wheezing?

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

Correct answer: A

Rationale: The correct answer is A, Albuterol 3 ml via nebulizer. Albuterol is a fast-acting bronchodilator that helps relieve wheezing by relaxing the muscles in the airways, making it the first-line treatment for wheezing caused by bronchospasms in allergic reactions. Methylprednisolone (Choice B) is a corticosteroid used for its anti-inflammatory properties and is typically given after bronchodilators. Cromolyn (Choice C) is a mast cell stabilizer that is used for the prevention of asthma symptoms, not for immediate relief. Aminophylline (Choice D) is a bronchodilator that is less commonly used nowadays due to its narrow therapeutic window and potential for toxicity.

5. 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.
