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.
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Checking for placement by auscultating for air injected into the tube is an outdated and unreliable method.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 A
Explanation
Choice A: Metformin
Reason: Metformin is known to interact with contrast material, particularly iodinated contrast media, and can increase the risk of acute kidney injury (AKI). This interaction can lead to a condition known as contrast-induced nephropathy (CIN) or contrast-induced acute kidney injury (CI-AKI). Metformin is primarily excreted by the kidneys, and impaired renal function can lead to its accumulation, increasing the risk of lactic acidosis, a rare but serious complication. Therefore, it is generally recommended to withhold metformin before and after the administration of contrast media until renal function is confirmed to be normal.
Choice B: Carvedilol
Reason: Carvedilol is a beta-blocker used to treat high blood pressure and heart failure. It does not have a known interaction with contrast media that would increase the risk of acute kidney injury. Carvedilol primarily affects the cardiovascular system and does not significantly impact renal function or interact with contrast agents.
Choice C: Nitroglycerin
Reason: Nitroglycerin is used to treat angina and other heart conditions by dilating blood vessels. It does not interact with contrast media in a way that would increase the risk of acute kidney injury. Nitroglycerin’s primary effects are on the cardiovascular system, and it does not have nephrotoxic properties.
Choice D: Atorvastatin
Reason: Atorvastatin is a statin used to lower cholesterol levels. While it can have effects on liver enzymes and muscle tissue, it does not interact with contrast media to increase the risk of acute kidney injury. Atorvastatin is metabolized by the liver and does not significantly impact renal function.
Correct Answer is B
Explanation
Choice A: You May Bring Some Music to Listen to for Distraction
Bringing music for distraction is generally not a standard instruction given before an EEG. While listening to music might help some patients relax, it is not a critical part of the preparation for the test. The primary focus of EEG preparation is to ensure accurate readings of brain activity, which can be influenced by various factors such as medication and sleep.
Choice B: Do Not Take Any Sedatives 12 to 24 Hours Before the Test
Avoiding sedatives before an EEG is crucial because these medications can alter brain activity and affect the test results. Sedatives can suppress the electrical activity in the brain, leading to inaccurate readings. Therefore, it is essential for patients to avoid taking any sedatives 12 to 24 hours before the test to ensure the EEG captures the brain’s natural activity.
Choice C: You Will Need to Have Someone to Drive You Home
This instruction is typically given if the patient is expected to be sedated or if the test involves procedures that might impair their ability to drive. However, for a standard EEG, patients are usually not sedated, and there is no need for someone to drive them home. This instruction is more relevant for other types of medical procedures that involve sedation.
Choice D: Please Do Not Have Anything to Eat or Drink After Midnight
Fasting is not a standard requirement for an EEG. Patients are generally allowed to eat and drink before the test. However, they are often advised to avoid caffeine as it can affect brain activity. The instruction to avoid food and drink after midnight is more commonly associated with procedures that require anesthesia or sedation, not an EEG.
