1. What is the expected ECG finding in a patient with hypokalemia?

A. Flattened T waves
B. Elevated ST segments
C. Widened QRS complexes
D. Widened QRS complexes on the ECG

Correct answer: A

Rationale: The correct answer is A: Flattened T waves. In hypokalemia, there is a decrease in serum potassium levels, which can lead to various ECG changes. One of the classic ECG findings associated with hypokalemia is the presence of flattened T waves. These T wave abnormalities are typically seen in multiple leads. Choice B, elevated ST segments, is not a typical ECG finding in hypokalemia. Choice C, widened QRS complexes, is more commonly associated with hyperkalemia rather than hypokalemia. Choice D is redundant and not a standard way of describing ECG findings.

2. What medication should be given first to a patient experiencing wheezing and coughing due to an allergic reaction?

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

Correct answer: A

Rationale: The correct answer is Albuterol 3 ml via nebulizer. Albuterol is a bronchodilator that helps relieve wheezing and coughing by opening up the airways, making it the first-line treatment for allergic reactions presenting with these symptoms. Cromolyn and aminophylline are not typically used as first-line treatments for acute allergic reactions with wheezing and coughing. Methylprednisolone, a corticosteroid, may be beneficial for inflammation in the setting of an allergic reaction but is not the initial medication of choice to address wheezing and coughing.

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 action should a healthcare provider take if a patient reports 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: When a patient reports cramping during enema administration, the best action is to lower the height of the enema solution container. This adjustment helps relieve abdominal cramping by slowing down the flow of the enema, making it more comfortable for the patient. Increasing the flow of the solution (choice B) would exacerbate the cramping. Stopping the procedure and removing the tubing (choice C) may be necessary in some cases but should not be the first response to cramping. Continuing the enema at a slower rate (choice D) might not be as effective as lowering the height of the solution container in addressing the cramping.

5. What are the expected symptoms of 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: The correct answer is A: 'Gradual loss of function on one side of the body.' In a thrombotic stroke, a clot blocks a cerebral artery, leading to a gradual onset of symptoms such as weakness, numbness, or paralysis on one side of the body. Choice B, 'Sudden loss of consciousness,' is more characteristic of a hemorrhagic stroke. Choice C, 'Severe headache and confusion,' are often associated with subarachnoid hemorrhage rather than thrombotic stroke. Choice D, 'Loss of sensation in the affected limb,' is not a typical symptom pattern for a thrombotic stroke, which usually presents with motor deficits.
