Correct Answer is A

Explanation

A.Adequate protein intake is essential for skin repair and maintaining skin integrity. Protein helps in the healing process, supports the immune system, and strengthens the skin, making it more resistant to breakdown. This is a crucial intervention for preventing pressure ulcers and promoting overall skin health in older adults.

B.Massaging bony prominences is not recommended as it can cause friction and damage to already vulnerable skin, increasing the risk of skin breakdown rather than preventing it. Gentle repositioning is preferred to relieve pressure.

C.Clients at risk for skin breakdown should typically be repositioned at least every 2 hours, not every 3 hours, to relieve pressure and reduce the risk of developing pressure ulcers. Therefore, this option is not ideal as stated.

D.While keeping the skin dry is important, cornstarch is not recommended because it can cake and cause friction, which may lead to skin breakdown. Using moisture-wicking products or barrier creams is more appropriate for maintaining skin dryness and integrity.

A. 8.0 B. 6.0 C. 7.0 D. 4.0

Correct Answer is D

Explanation

A. 8.0: An aspirate pH of 8.0 would indicate an alkaline substance. This would not be typical of stomach contents, which are acidic. An alkaline pH might suggest placement in the intestines or respiratory tract.

B. 6.0: While this is less alkaline than 8.0, it is still not within the typical range for stomach contents. Stomach aspirate is generally more acidic.

C. 7.0: A pH of 7.0 is neutral. Stomach contents are typically more acidic, so a neutral pH would not be consistent with correct NG tube placement in the stomach.

D. 4.0: This is within the acidic range and is consistent with the pH of stomach contents. It would be considered an indication of correct NG tube placement in the stomach.
