A small-bore feeding tube is placed. Which technique will the nurse use to best verify tube placement?
Auscultation
X-ray
Aspiration of contents
pH testing
The Correct Answer is B
A: Auscultation, or listening for air injected into the tube, is not a reliable method for verifying feeding tube placement. It can lead to false positives and does not confirm the tube’s location accurately.
B: X-ray is the gold standard for verifying feeding tube placement. It provides a clear image of the tube’s position, ensuring it is correctly placed in the stomach or small intestine, reducing the risk of complications.
C: Aspiration of contents can help verify placement by checking the appearance and pH of the aspirate. However, it is not as definitive as an X-ray and can sometimes be inconclusive.
D: pH testing of aspirate can indicate whether the tube is in the stomach (acidic pH) or intestines (less acidic). While useful, it is not as reliable as an X-ray for confirming placement.

Correct Answer is D
Explanation
A: Stopping an antibiotic once feeling better is incorrect. Antibiotics should be taken for the full prescribed course to ensure the infection is fully treated and to prevent antibiotic resistance.
B: Skipping a dose if 30 minutes late is not recommended. Most medications can be taken within a short window of the scheduled time. The patient should follow specific instructions provided by the healthcare provider.
C: Parenteral medications are administered via injection and do not need to be taken with food. This statement indicates a misunderstanding of the medication route.
D: Rotating the sites for a transdermal patch is correct. This practice helps prevent skin irritation and ensures consistent absorption of the medication.
Correct Answer is C
Explanation
The correct answer is C.
A: Consulting a dietitian is a beneficial order for a patient with a pressure ulcer. Proper nutrition, especially adequate protein intake, is crucial for wound healing. A dietitian can help ensure the patient receives the necessary nutrients to support tissue repair and recovery.
B: Applying a hydrogel dressing is appropriate for a clean, granulating Stage II pressure ulcer. Hydrogel dressings maintain a moist wound environment, which promotes healing and provides pain relief. They are suitable for wounds with minimal to moderate exudate.
C: Cleaning the wound with hydrogen peroxide is not recommended for a healing pressure ulcer. Hydrogen peroxide can damage healthy granulating tissue and delay the healing process. It is better to use saline or a wound cleanser that does not harm the new tissue.
D: Using a low-air-loss therapy unit is beneficial for patients with pressure ulcers. These units help reduce pressure on the skin, improve circulation, and prevent further skin breakdown. They are an effective part of pressure ulcer management.
