The nurse is screening a client prior to an magnetic resonance imaging (MRI). What information is important to report to the health care provider before the MRI?

The traces that should require immediate follow-up by the nurse are:

● Pacer spikes occur directly before the T waves.

Pacer spikes occurring on the T waves indicate an issue with the pacemaker's timing or sensing. This could lead to inappropriate pacing or pacing during the refractory period, which can be detrimental to the client's heart function.

● The heart rate is outside of programmed parameters.

If the heart rate is outside of the programmed parameters set for the client's pacemaker, it may indicate a malfunction or failure of the device or a change in the client's cardiac status. It is important for the nurse to assess the client's condition and notify the healthcare provider for further evaluation and intervention.

Let's review the other options and explain why they do not require immediate follow-up:

Pacer spikes are adequate in number: This indicates that the pacemaker is delivering the appropriate number of electrical impulses as programmed. As long as the other parameters are normal, this finding does not require immediate follow-up.

Pacer spikes occur directly before the P waves: This is the desired and expected pattern for a pacemaker in normal sinus rhythm. It indicates proper timing and coordination between the pacemaker and the client's intrinsic electrical activity.

Pacer spikes occur directly before the QRS waves: This is also the desired and expected pattern for a pacemaker in clients with ventricular pacing. It indicates proper timing and coordination between the pacemaker and the client's intrinsic electrical activity.

The heart rate is within programmed parameters: If the heart rate falls within the programmed parameters set for the client's pacemaker, it indicates that the device is functioning appropriately in maintaining the desired heart rate.

Choice D: This question is crucial as it addresses the client's adherence to their prescribed medication regimen for managing high blood pressure. Consistent medication use is essential for controlling blood pressure and reducing the risk of complications associated with hypertension. The elevated blood pressure reading suggests that the current medication regimen may not be effectively controlling the client's blood pressure. By assessing medication adherence, the nurse can determine if non-adherence is contributing to the high blood pressure reading or if adjustments to the medication regimen are required.

"Have you recently taken any antihistamines?": Asking about recent antihistamine use is not directly relevant to the client's high blood pressure reading of 210/106 mm Hg. Antihistamines are medications primarily used to relieve allergy symptoms and do not typically have a significant impact on blood pressure levels.

"Have there been recent stressful events in your life?": While stress can contribute to temporary increases in blood pressure, asking about recent stressful events is not the most critical follow-up question in this situation. The client's blood pressure reading of 210/106 mm Hg indicates a severe elevation that requires immediate attention and management beyond stress reduction alone.

"Did you take any acetaminophen today?": Acetaminophen, also known as paracetamol, is a pain reliever and fever reducer. It does not typically have a significant effect on blood pressure. Therefore, asking about acetaminophen use is not the most relevant follow-up question for the client's high blood pressure reading.
