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 client has a permanent cardiac pacemaker

The client has a history of atherosclerosis.

The client took the prescribed heart medications today

The client has an allergy to shellfish.

Answer and Explanation

The Correct Answer is A

Having a permanent cardiac pacemaker is a significant factor that needs to be communicated to the health care provider before undergoing an MRI. Magnetic resonance imaging (MRI) uses powerful magnets, radio waves, and a computer to create detailed images of the body. The presence of a cardiac pacemaker can be a contraindication for undergoing an MRI because the strong magnetic field can potentially interfere with the functioning of the pacemaker or cause it to malfunction. It is crucial to assess the compatibility of the pacemaker with the MRI machine and to take appropriate precautions or make necessary arrangements to ensure the safety of the client during the procedure.

While the other pieces of information provided may be relevant to the client's overall health and medical history, they may not have a direct impact on the safety or feasibility of undergoing an MRI.

Correct Answer is C

Explanation

The most important finding to report to the health care provider would be the serum potassium level of 3.0 mEq. This is an extremely low potassium level (normal range is typically 3.5-5.0 mEq/L), which can indicate a potentially life-threatening condition called hypokalemia. Furosemide (Lasix) is a diuretic medication that can cause potassium loss in the urine, and a low potassium level can lead to serious cardiac and muscle abnormalities. It is crucial to report this finding promptly to the health care provider for appropriate intervention and monitoring.

Blood glucose level of 175 mg/dL: While an elevated blood glucose level can be a concern, especially for individuals with diabetes, it is not the most critical finding in this situation. The client's primary concern is hypertension, and the administration of IV furosemide is aimed at managing blood pressure. The elevated blood glucose level should still be addressed and monitored, but it is not as urgent as the low potassium level.

Orthostatic systolic BP decrease of 12 mm Hg: Orthostatic hypotension refers to a significant decrease in blood pressure upon standing up. While it is important to assess and manage orthostatic changes, a decrease of 12 mm Hg in systolic blood pressure alone may not be considered clinically significant. It could be a normal response for some individuals. However, if the client experiences symptoms such as dizziness or lightheadedness upon standing, further evaluation may be necessary. Nonetheless, it is not as urgent as the low potassium level.

Current blood pressure reading of 166/94 mm Hg: While this blood pressure reading indicates hypertension, it is not the most critical finding to report in this situation. The nurse is preparing to administer furosemide (Lasix), which is a medication commonly used to treat hypertension. It is expected that the blood pressure will be high before administering the medication. The goal is to monitor the blood pressure after the administration to assess the effectiveness of the medication.

A. Instruct the client to drink 1 L of water before the test. B. Administer intravenous (IV) benzodiazepines and opioids. C. Inform the client that the client will remain on bed rest following the procedure D. Inform the client that an access line will be initiated in the femoral artery.

Correct Answer is D

Explanation

Transesophageal echocardiography is a diagnostic procedure that involves inserting a probe into the esophagus to obtain detailed images of the heart. In some cases, an access line may be initiated in the femoral artery to monitor blood pressure during the procedure and administer medications if needed. Informing the client about this aspect of the procedure helps ensure that they are aware of what to expect and can provide informed consent.

Let's go through the other options and explain why they are not the most appropriate actions:

Instruct the client to drink 1 L of water before the test: This action is not necessary for transesophageal echocardiography. Drinking water before the test is typically done for certain abdominal or pelvic ultrasound examinations to provide better visualization. However, for TEE, the probe is inserted into the esophagus, and drinking water is not required.

Administer intravenous (IV) benzodiazepines and opioids: The administration of intravenous benzodiazepines and opioids is not a routine part of preparing a client for TEE. The need for sedation or analgesia during the procedure would be determined based on the individual client's condition and level of discomfort.

Inform the client that the client will remain on bed rest following the procedure: While some post-procedure instructions may be given to the client, such as avoiding eating or drinking until the effects of sedation wear off, informing the client that they will remain on bed rest following the procedure is not a speciﬁc requirement for TEE. Post-procedure instructions can vary depending on the individual client's condition and the healthcare provider's recommendations.
