what ph value should the nurse expect when confirming placement of the nasogastric tube using the ph method? what ph value should the nurse expect for respiratory or small intestine secretions?

Sagot :

The value that the nurse must obtain from the stomach is a pH of 5.

A nasogastric tube is a medical device that is inserted through the patient's nose into the stomach to introduce food and medicine directly.

To know that the probe is placed in the desired position (in the stomach) a pH dating method is used.

In this method, the location of the probe is verified by absorbing mucus and checking its pH. Depending on the location, both the pH and the color of the mucus will be different. For example:

  • Stomach mucus should have a pH of 1 to 5
  • Mucus in the airways has a pH of 6
  • Mucus in the small intestine has a pH of 6 or higher

This dating is used to avoid sending food or medicine to the wrong place in the body, which could put the patient's life at risk.
