A nurse is about to administer an intermittent enteral feeding to a client who has an NG tube in place. Besides obtaining an x-ray, which of the following methods should the nurse use to verify the placement?

Inject air and listen for bubbling.

Test the pH of the gastric aspirate.

Measure the gastric residual.

Add food coloring to the formula.

Answer and Explanation

The Correct Answer is B

This is done by aspirating a small amount of stomach contents and testing the pH using pH paper or a pH indicator strip. The pH of stomach contents is typically acidic (pH less than 5), indicating proper placement in the stomach.

Injecting air and listening for bubbling is not a reliable method to verify tube placement, as it can lead to complications such as pneumothorax.

Measuring gastric residual is done to assess the amount of gastric contents remaining in the stomach, but it does not confirm tube placement.

Adding food coloring to the formula is not a standard practice and does not provide reliable confirmation of tube placement.

X-ray is the gold standard method to confirm tube placement but is not typically done before every intermittent feeding unless there are concerns about tube placement

Correct Answer is D

Explanation

Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver. Therefore, it is important to monitor the client's clotting ability to ensure that the medication is working properly and not causing any adverse eﬀects. The laboratory test that is used to monitor warfarin therapy is the prothrombin time (PT), which measures the time it takes for the blood to clot. The nurse should monitor the client's PT regularly and adjust the dosage of warfarin as necessary to maintain the therapeutic range. Option a (Triiodothyronine) is a thyroid hormone and is not directly related to warfarin therapy. Option b (Blood urea nitrogen) is a measure of kidney function and is also not directly related to warfarin therapy. Option c (Arterial blood gases) is a measure of oxygen and carbon dioxide levels in the blood and is not related to warfarin therapy.

A. A client who had a renal biopsy 3 hr ago and has pink-tinged urine B. A client who has a femur fracture and reports numbness of the toes C. A client who has cirrhosis and severe pruritus D. A client who had a laparoscopic appendectomy 8 hr ago and is awaiting discharge

Correct Answer is B

Explanation

Numbness of the toes in a client with a femur fracture may indicate neurovascular compromise, which requires immediate attention.

It could be a sign of impaired circulation or nerve damage, and prompt assessment is needed to prevent further complications or permanent damage.
