Which technique is most reliable to confirm correct placement of a nasogastric tube prior to initiating tube feedings?

Fluoroscopy to identify location.

Aspirate contents and measure the pH.

Inject air and listen for gurgling sounds.

Observe for bubbles after placing the end of the tube in a cup of water.

Answer and Explanation

The Correct Answer is B

This is because the pH of gastric contents is acidic (less than 5.5) and can indicate that the tube is in the stomach. This method is predictive of the correct placement of a nasogastric tube.

Choice A is wrong because fluoroscopy is not the most reliable method to confirm the correct placement of a nasogastric tube. It is an imaging technique that uses X-rays to show the movement of the tube, but it is not always available or feasible.

Choice C is wrong because injecting air and listening for gurgling sounds is not a reliable method to confirm the correct placement of a nasogastric tube. It can cause false-positive results and does not differentiate between the stomach and the respiratory tract.

Choice D is wrong because observing for bubbles after placing the end of the tube in a cup of water is not a reliable method to confirm the correct placement of a nasogastric tube. It can also cause false-positive results and does not differentiate between the stomach and the respiratory tract.

Correct Answer is C

Explanation

This would help the client to feel valued, respected and involved in their own care, which can enhance their self-esteem.

Choice A is wrong because adding a nursing diagnosis of lowered self-esteem to the care plan does not address the underlying causes of the problem or provide any interventions to improve it.

It may also label the client and make them feel worse.

Choice B is wrong because giving praise for every decision the client makes is not realistic or sincere.

It may also undermine the client’s confidence and autonomy by implying that they need constant approval from others.

Choice D is wrong because modeling competent care for the client does not necessarily help them to maintain their self-esteem.

It may even make them feel inadequate or dependent on the nurse.

A. “I will take my water pill in the morning so I don’t have to go to the bathroom so much at night.”. B. “I will limit how much I drink to reduce my chance of having an accident.”. C. “I plan to use the commode next to my bed instead of trying to make it to the bathroom.”. D. “I want to use the commode in my room instead of wearing adult briefs.”.

Correct Answer is B

Explanation

Limiting fluid intake can lead to dehydration and concentrated urine, which can irritate the bladder and increase the risk of infection. Older adults should drink about 2 liters of fluid per day unless they have a medical condition that requires fluid restriction.

Choice A is correct because taking diuretics in the morning can reduce nocturia and improve sleep quality.

Choice C is correct because using a commode next to the bed can prevent falls and injuries that may occur when trying to reach the bathroom in a hurry.

Choice D is correct because using a commode in the room can preserve dignity and comfort, and reduce skin breakdown and odor that may result from wearing adult briefs.
