A nurse is educating a patient who has been prescribed a nasogastric tube (NG) to treat a pyloric obstruction. Which of the following reasons for the use of the nasogastric tube should the nurse include in the teaching?
To determine the pH of the gastric secretions.
To supply nutrients via tube feedings.
To administer medications.
To decompress the stomach.
The Correct Answer is D
Choice A rationale
While a nasogastric tube can be used to determine the pH of gastric secretions, this is not typically the primary reason for its use in the treatment of pyloric obstruction.
Choice B rationale
While nasogastric tubes can be used to supply nutrients via tube feedings, this is not typically the primary reason for its use in the treatment of pyloric obstruction. In the case of pyloric obstruction, the focus is usually on relieving the obstruction rather than on feeding.
Choice C rationale
While nasogastric tubes can be used to administer medications, this is not typically the primary reason for its use in the treatment of pyloric obstruction.
Choice D rationale
The primary reason for the use of a nasogastric tube in the treatment of pyloric obstruction is to decompress the stomach. Pyloric obstruction can cause a buildup of gastric contents above the level of the obstruction, leading to symptoms such as nausea and vomiting. A nasogastric tube can be used to remove these contents and relieve symptoms.

Correct Answer is A
Explanation
Choice A rationale
A stool guaiac test is a simple check to find blood in your stool. It involves smearing a tiny amount of your stool on a special card, which is then tested for hidden blood. This test helps detect problems like bleeding ulcers or colon cancer in an early stage when they might not show other symptoms. The stool guaiac test looks for hidden (occult) blood in a stool sample. It can find blood even if you cannot see it yourself. It is a common type of fecal occult blood test (FOBT). Guaiac is a substance from a plant that is used to coat the FOBT test cards to make them able to detect blood.
Choice B rationale
Steatorrhea refers to the presence of excess fat in the stool. While this can be a symptom of various digestive disorders, it is not what a stool guaiac test is designed to detect. The primary purpose of a stool guaiac test is to identify hidden blood in the stool, which can be an indicator of conditions such as gastrointestinal bleeding or colon cancer.
Choice C rationale
While bacteria can be present in the stool and certain tests are designed to detect them, a stool guaiac test is not one of these. The stool guaiac test is specifically designed to detect the presence of hidden blood in the stool. The presence of blood can indicate a variety of conditions, including gastrointestinal bleeding or colon cancer.
Choice D rationale
Yeast can be present in the stool, and certain tests can detect it. However, a stool guaiac test is not designed to detect yeast. The primary purpose of a stool guaiac test is to identify hidden
blood in the stool, which can be an indicator of conditions such as gastrointestinal bleeding or colon cancer.
Correct Answer is D
Explanation
Choice A rationale
While assessing the client’s skin for a rash could be part of the overall assessment of the client’s condition, it is not the priority action when a client is experiencing chills and back pain during a blood transfusion.
Choice B rationale
Notifying the provider is an important step when a client is experiencing a reaction to a blood transfusion, but it is not the first action that should be taken.
Choice C rationale
Covering the client with a blanket may provide comfort to the client, but it does not address the underlying issue of a potential transfusion reaction.
Choice D rationale
The priority action when a client is experiencing chills and back pain during a blood transfusion is to stop the transfusion. This is because these symptoms could indicate a transfusion reaction, which can be serious.
