The nurse is assessing for correct placement of a nasogastric tube. The nurse aspirates the stomach contents, checks the gastric pH, and notes a pH of 7.35. Based on this information, which action should the nurse take at this time?

Document that the nasogastric tube is in the correct place.

Notify the health care provider.

Check for placement by auscultating for air injected into the tube.

Retest the pH using another strip.

Answer and Explanation

The Correct Answer is B

Choice A Reason:

Documenting that the nasogastric tube is in the correct place is not appropriate in this scenario. A gastric pH of 7.35 is too high for stomach contents, which typically have a pH between 1.5 and 3.5. This high pH suggests that the tube may be misplaced, possibly in the respiratory tract or another non-gastric location. Therefore, documenting the tube as correctly placed could lead to serious complications if the tube is indeed misplaced.

Choice B Reason:

Notifying the health care provider is the most appropriate action. A pH of 7.35 is indicative of a potential misplacement of the nasogastric tube. The health care provider needs to be informed immediately to take corrective actions, such as ordering an X-ray to confirm the tube’s placement or re-evaluating the tube’s position. This step is crucial to ensure patient safety and prevent complications such as aspiration pneumonia or other adverse effects.

Choice C Reason:

Checking for placement by auscultating for air injected into the tube is an outdated and unreliable method. This technique can sometimes give false assurance of correct placement, as the sound of air can be heard even if the tube is in the respiratory tract. Current best practices recommend using pH testing and radiographic confirmation for accurate placement verification.

Choice D Reason:

Retesting the pH using another strip might seem like a reasonable step, but it is not the best immediate action. If the initial pH test shows a value of 7.35, it is unlikely that retesting will yield a significantly different result. The priority should be to notify the health care provider to address the potential misplacement promptly.

Correct Answer is ["C","D","E"]

Explanation

Choice A Reason:

Provide continued sedation.

Providing continued sedation is not typically necessary after a cardioversion. The sedation used during the procedure is usually short-acting, and the client should begin to wake up shortly after the procedure is completed. Continuous sedation is not required unless there are specific medical reasons, which should be determined by the healthcare provider.

Choice B Reason:

Remove crash cart from the room.

The crash cart should remain in the room until the client is fully stable. Removing it immediately after the procedure is not advisable because the client may still be at risk for complications such as arrhythmias or other cardiac events. Keeping the crash cart nearby ensures that emergency equipment is readily available if needed.

Choice C Reason:

Assess the chest for burns.

Assessing the chest for burns is an important nursing action following a cardioversion. The electrical shock delivered during the procedure can cause burns on the skin where the electrodes were placed. It is essential to check for any signs of burns or skin irritation and provide appropriate care if needed.

Choice D Reason:

Ensure electrodes are in place for continued monitoring.

Ensuring that the electrodes are in place for continued monitoring is crucial. Continuous cardiac monitoring is necessary to observe the client’s heart rhythm and detect any potential complications or recurrence of arrhythmias. Proper placement and function of the electrodes are essential for accurate monitoring.

Choice E Reason:

Document results of the procedure.

Documenting the results of the procedure is a critical nursing action. Accurate documentation includes noting the client’s response to the cardioversion, any complications, and the current heart rhythm. This information is vital for ongoing care and communication with the healthcare team.

A. Instruct the patient to withhold any medication for diuretic therapy. B. Prepare to administer fluids 2 hours before the procedure for patients with renal dysfunction. C. Advise the patient to take all anticoagulants. D. Administer steroids if the patient has an allergy to iodine-based contrast. E. Ensure that the patient is NPO for a minimum of 2 hours before the procedure.

Correct Answer is ["A","C","D","E"]

Explanation

Choice A: Instruct the patient to withhold any medication for diuretic therapy.

Reason: Diuretics can lead to dehydration and electrolyte imbalances, which can complicate the cardiac catheterization procedure. Withholding diuretics helps to maintain fluid balance and reduce the risk of complications during the procedure

Choice B: Prepare to administer fluids 2 hours before the procedure for patients with renal dysfunction.

Reason: Administering fluids before the procedure helps to prevent contrast-induced nephropathy, especially in patients with renal dysfunction. Hydration helps to flush out the contrast material used during the procedure, reducing the risk of kidney damage.

Choice C: Advise the patient to take all anticoagulants.

Reason: This choice is incorrect. Patients are usually advised to withhold anticoagulants before a cardiac catheterization to reduce the risk of bleeding complications. The decision to continue or withhold anticoagulants should be based on a careful assessment of the patient’s risk of thromboembolism versus the risk of bleeding.

Choice D: Administer steroids if the patient has an allergy to iodine-based contrast.

Reason: Administering steroids is a common premedication strategy for patients with a known allergy to iodine-based contrast media. Steroids help to reduce the risk of an allergic reaction during the procedure.

Choice E: Ensure that the patient is NPO for a minimum of 2 hours before the procedure.

Reason: Ensuring that the patient is NPO (nothing by mouth) helps to reduce the risk of aspiration during the procedure. Typically, patients are advised to be NPO for 6-8 hours before the procedure, but a minimum of 2 hours is essential.
