A nurse is caring for a client who has an NG tube. The nurse tests the pH of the secretions to determine if the tube is correctly placed. Which of the following readings should the nurse expect?
pH 1-4
pH 5-7
pH 8-10
pH 11-14
The Correct Answer is A
A reason:
A pH reading of 1-4 is expected for gastric contents. This acidic range indicates that the NG tube is correctly placed in the stomach, where gastric secretions have a low pH due to hydrochloric acid.
B reason:
A pH reading of 5-7 is more indicative of respiratory secretions or the contents of the small intestine, not the stomach. This range suggests that the NG tube may be incorrectly placed.
C reason:
A pH reading of 8-10 is too alkaline for gastric contents and indicates incorrect tube placement. This range could suggest the presence of intestinal or respiratory secretions, not gastric.
D reason:
A pH reading of 11-14 is highly alkaline and unlikely to be encountered in clinical practice for this purpose. Such a high pH is not compatible with gastric contents and suggests a significant error or contamination in the test.

Correct Answer is D
Explanation
A reason:
Using lotion on irritated skin before applying a new patch is incorrect. Lotion can interfere with the adhesion and absorption of the medication from the patch. It's important to keep the skin clean and dry.
B reason:
Removing the old patch and applying a new one in the same location is not recommended. The skin needs time to recover from the adhesive and medication exposure. Patches should be rotated to different areas to prevent skin irritation.
C reason:
Pressing the patch securely in place is important, but the statement is incomplete without mentioning the need to clean and dry the area first. Proper skin preparation is crucial for effective patch adhesion.
D reason:
Cleaning and drying the area before applying the patch is correct. This ensures that the patch adheres properly and that the medication is effectively absorbed through the skin.
Correct Answer is C
Explanation
A reason:
Completing a report is not the priority action after administering pain medication. Reassessing the client's pain level and effectiveness of the medication is more crucial at this point.
B reason:
Calling the client's provider may be necessary if there are issues or if the pain is not managed, but the first step should be reassessing the client to determine the need for further action.
C reason:
Reassessing the client is correct. This helps determine the effectiveness of the pain medication and the need for additional interventions. It is important to monitor and document the client's response to the medication.
D reason:
Notifying the nurse manager is not the first action needed. The nurse manager can be informed if there are significant issues, but reassessing the client comes first to understand the medication's impact.
