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: Incorrect. Leaning on the crutches for support while standing still is not the correct way to use crutches. It can lead to discomfort and instability.
B: Correct. The client should advance the unaffected leg first while climbing stairs when using crutches. This technique ensures better stability and safety during stair ascent.
C: Incorrect. Standing 5 cm (2 in) from the front of a chair before sitting is not directly related to the use of crutches.
D: Incorrect. Bearing weight on the axilla while standing in the tripod position is not the correct way to use crutches. The tripod position is used for resting, not weight bearing.
Correct Answer is B
Explanation
A. Empty the urine drainage bag every 12 hours: While it's essential to empty the urine drainage bag regularly to prevent it from becoming too full, emptying it every 12 hours alone is not sufficient to prevent urinary tract infections (UTIs).
B. Drain the urine from the tubing before ambulation: Correct. Before the client ambulates or moves, the nurse should ensure that the urinary catheter's tubing is emptied. This prevents urine from flowing back into the bladder, reducing the risk of UTIs.
C. Use clean technique for urine specimen collection: While using clean technique during urine specimen collection is important for preventing contamination, it is not the primary action needed to prevent UTIs in a client with an indwelling urinary catheter.
D. Hang the urine drainage bag at the level of the bladder: While proper positioning of the drainage bag is essential for optimal urine flow and to prevent backflow, it alone is not sufficient to prevent UTIs.
