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 C
Explanation
A. The client has smooth, brown, irregular lesions on the back of each hand – These are likely seborrheic keratoses, which are benign, age-related lesions and do not usually require reporting unless changes suggest malignancy.
B. The client has glossy, white arches around the periphery of the corneas – This is commonly arcus senilis, a normal, benign finding in older adults that does not require intervention.
C. The client reports urinary incontinence – Urinary incontinence can be a sign of underlying issues such as a urinary tract infection or neurological disorder, necessitating further evaluation by the provider.
D. The client reports a decreased sense of taste – A reduced sense of taste is a typical age-related change and does not generally need to be reported unless it is sudden or associated with other symptoms.
Correct Answer is A
Explanation
A. Precontemplation
According to evidence-based practice, the nurse should identify that precontemplation is the first stage the client will experience when using the stages of health behavior change. In this stage,
the client avoids discussing the behavior and does not intend to make a change in behavior. The stages of health behavior change are pre contemplation, contemplation, preparation, action and the maintenance stage
B. Preparation INCORRECT
The nurse should identify that preparation is the third stage the client will experience when using the stages of health behavior change. In this stage, the client plans to make minor changes to behavior. However, according to evidence-based practice, another stage occurs prior to the preparation stage.
