Which symptom will the nurse anticipate in a patient diagnosed with supraventricular tachycardia (SVT) with a non-sustained ventricular response?

Assessment: Patient had 2 semi-formed bowel movements 1 hour after administration of the medication

Choice A Reason:

Assessment: Patient denies vomiting

This choice is not directly related to the effectiveness of Kayexalate. Vomiting can be a symptom of hyperkalemia, but the absence of vomiting does not indicate that the medication is working. Kayexalate works by binding potassium in the intestines and removing it through the stool, so the presence of bowel movements is a more direct indicator of its effectiveness.

Choice B Reason:

ECG: Flattening of QRS complex angle

Flattening of the QRS complex angle is not a typical ECG change associated with hyperkalemia or its treatment. Hyperkalemia typically causes widening of the QRS complex, and effective treatment would normalize this. Therefore, this choice is not correct.

Choice C Reason:

ECG: Widening of the QRS complex

Widening of the QRS complex is a sign of hyperkalemia, not its resolution. If the medication is effective, the QRS complex should return to a normal width. Therefore, this choice is not correct.

Choice D Reason:

Assessment: Patient consumed 60% of meal

While nutritional intake is important, it is not a direct indicator of the effectiveness of Kayexalate. The medication’s effectiveness is better assessed by changes in potassium levels and related symptoms, not by meal consumption.

Choice E Reason:

Assessment: Patient denies nausea

Similar to vomiting, nausea can be a symptom of hyperkalemia, but the absence of nausea does not indicate that the medication is working. The effectiveness of Kayexalate is better assessed by the presence of bowel movements and changes in potassium levels.

Choice F Reason:

Assessment: Patient had 2 semi-formed bowel movements 1 hour after administration of the medication

This is the correct answer. Kayexalate works by binding potassium in the intestines and removing it through the stool. The presence of bowel movements indicates that the medication is working to remove potassium from the body. This is a direct and relevant assessment finding.

Choice G Reason:

ECG: Shortening of P wave duration

Shortening of the P wave duration is not a typical ECG change associated with hyperkalemia or its treatment. Therefore, this choice is not correct.

Choice H Reason:

Assessment: Patient denies pain

Pain is not a typical symptom of hyperkalemia, and its absence does not indicate that the medication is working. Therefore, this choice is not correct.

Choice I Reason:

ECG: Reduction of T wave amplitude

Reduction of T wave amplitude can be a sign of hypokalemia, not hyperkalemia. Effective treatment of hyperkalemia would normalize the T wave amplitude, not reduce it. Therefore, this choice is not correct.

Step 1: Calculate the total infusion time in minutes.

8 hours × 60 minutes/hour = 480 minutes

Result at each step = 480 minutes

Step 2: Calculate the total number of drops to be infused.

1,000 mL × 15 drops/mL = 15,000 drops

Result at each step = 15,000 drops

Step 3: Calculate the infusion rate in drops per minute.

15,000 drops ÷ 480 minutes = 31.25 drops/minute

Result at each step = 31.25 drops/minute

Step 4: Round to the nearest whole number if necessary.

31.25 drops/minute rounds to 31 drops/minute

Result at each step = 31 drops/minute

Therefore, the nurse should run the IV infusion at a rate of 31 drops per minute.
