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: The statement “Benefit may outweigh the risk” is more applicable to Pregnancy Risk Category D or X drugs, where there is evidence of risk but potential benefits may justify use in certain situations.
B: Studies showing fetal risk are associated with Pregnancy Risk Category D or X drugs. Category A drugs have not shown fetal risk in controlled studies.
C: Drugs that are contraindicated in pregnant women fall under Pregnancy Risk Category X, where the risks clearly outweigh any potential benefits.
D: Fetal harm is unlikely for Pregnancy Risk Category A drugs. These drugs have been tested in controlled studies and have not shown any risk to the fetus, making them safe for use during pregnancy.
Correct Answer is C
Explanation
A: Intact skin with localized erythema describes a stage 1 pressure injury, where the skin is not broken but shows signs of redness and irritation. This stage does not involve any loss of skin layers.
B: Full-thickness skin loss with visible adipose tissue is characteristic of a stage 3 pressure injury. At this stage, the injury extends through the full thickness of the skin and exposes fat tissue, but not muscle, bone, or tendon.
C: Partial-thickness skin loss with red tissue in the wound bed is indicative of a stage 2 pressure injury. This stage involves damage to the epidermis and dermis, resulting in a shallow, open wound with a red or pink wound bed. It may also present as an intact or ruptured blister.
D: Full-thickness skin loss with visible bone describes a stage 4 pressure injury. This stage involves extensive destruction, with tissue loss extending to muscle, bone, or supporting structures.
