A nurse is preparing to administer enteral feeding to a client who has an NG tube in place. Which of the following methods should the nurse use to verify the correct placement of the NG tube?
Check the pH of the gastric aspirate.
Observe the color of the gastric aspirate after adding blue dye to the formula.
Auscultate over the epigastrium.
Measure the length of the inserted NG tube.
The Correct Answer is A
A: Correct. Checking the pH of the gastric aspirate is the most reliable method to verify the correct placement of the NG tube. Gastric aspirate typically has an acidic pH (pH < 5), indicating that the tube is in the stomach.
B: Observing the color of the gastric aspirate after adding blue dye to the formula is not a standard or recommended method for verifying NG tube placement.
C: Auscultating over the epigastrium may help to identify the presence of air in the stomach, but it does not confirm that the NG tube is correctly placed in the stomach or the intestines.
D: Measuring the length of the inserted NG tube can help determine the distance from the nose to the stomach, but it does not ensure correct placement in the stomach.

Correct Answer is B
Explanation
A. Restrict the client's visitors to the immediate family: While tuberculosis is a communicable disease, restricting visitors to the immediate family is not a standard precautionary measure. Visitors should be educated about infection control measures and individuals with active tuberculosis
may need to wear masks in certain situations.
B. Assign the client to a negative pressure airflow room: Correct. Clients with active tuberculosis should be placed in a negative pressure airflow room to prevent the spread of infectious airborne particles to other areas of the facility. Negative pressure ensures that air from the room does not flow to other parts of the facility.
C. Discard personal protective equipment outside the client's room: Personal protective equipment (PPE) should be removed and discarded according to facility policy, which often includes removing PPE inside the client's room and properly disposing of it afterward. The nurse should follow standard precautions for infection control.
D. Have the client wear a HEPA mask during transportation throughout the facility: While wearing a HEPA mask may be necessary for clients with tuberculosis, it is not related to the initial admission process. Clients with active tuberculosis may be asked to wear a HEPA mask during transportation when they need to leave their negative pressure room.
Correct Answer is D
Explanation
A. Provide an artificial voice box - This is not typically used for clients with aphasia as it does not address the communication barriers they face.
B. Avoid using facial gestures - Facial gestures can be a helpful non-verbal communication tool, especially for clients with aphasia, so avoiding them is not beneficial.
C. Speak to the client in a louder voice - Aphasia affects language processing, not hearing, so increasing volume does not aid in understanding.
D. Ask the client close-ended questions - This allows the client to respond with 'yes' or 'no', or other simple answers, which can be easier for someone with aphasia.
