A nurse is teaching a client who has a prescription of a nasogastric tube (NG) to treat a pyloric obstruction. Which of the following rationales for the use of the nasogastric tube should the nurse include in the teaching?
Administer medications
Supply nutrients via tube feedings
Decompress the stomach
D. Determine the pH of the gastric secretions
The Correct Answer is C
A. Administer medications:
While nasogastric tubes can be used to administer medications, this is not the primary rationale for their use in pyloric obstruction. The primary goal is often decompression.
B. Supply nutrients via tube feedings:
Providing nutrients via tube feedings is not the primary purpose in the context of a pyloric obstruction. Decompression is more relevant in this scenario.
C. Decompress the stomach:
Decompressing the stomach is a common use of nasogastric tubes in the context of pyloric obstruction. The tube helps to remove excess air and gastric contents, relieving pressure in the stomach.
D. Determine the pH of the gastric secretions:
While determining the pH of gastric secretions is a possible use, it is not the primary rationale for nasogastric tube placement in pyloric obstruction. The primary goal is often to relieve obstruction and decompress the stomach.

Correct Answer is D
Explanation
A. Applying a cold pack to the client's upper arm is not the first action. The priority is to assess and address the cause of the edema. Cold packs may be used for comfort, but they do not address the underlying issue.
B. Removing the PICC line is not the first action. Before considering removal, it is essential to assess the extent and cause of the edema. Removing the line without proper evaluation could lead to premature discontinuation of necessary treatment.
C. Notifying the provider who inserted the PICC line is important, but it is not the first action. The nurse needs to assess and intervene promptly. The provider should be informed after initial actions are taken.
D. Stopping the infusion and measuring the circumference of both upper arms is the first action. This helps determine the extent of the edema and whether it is related to the infusion. It is crucial to assess for complications such as infiltration or extravasation of the TPN solution.
Correct Answer is C
Explanation
A. Calcium:
While calcium levels can be affected in pancreatitis, it is more commonly associated with a decrease in calcium levels due to fat necrosis and the formation of calcium soaps. However, the primary electrolyte disturbance is more likely to involve magnesium.
B. Magnesium:
Magnesium levels may be decreased in acute pancreatitis due to factors such as vomiting, malabsorption, and poor oral intake. Hypomagnesemia is a possible consequence, but it's not as specific to pancreatitis as the elevation of amylase.
C. Amylase:
Elevated amylase levels are a hallmark of acute pancreatitis. Amylase is an enzyme released by the pancreas, and its elevation in the blood is a key diagnostic marker for pancreatitis.
D. RBC count:
Acute pancreatitis does not typically result in a significant impact on the red blood cell (RBC) count. The elevation of amylase and lipase levels, along with imaging studies, is more indicative of pancreatitis.
