A provider orders a diagnostic test for a client with a urinary tract infection. The test will determine the strain of bacteria causing the infection and determine the antibiotic that will treat the infection. The nurse knows this test is called which of the following?

A. Increased thickness of the subcutaneous skin layer - Aging typically results in thinning of the skin and subcutaneous tissue, making older adults more vulnerable to pressure ulcers rather than having increased thickness.

B. Changes in the character and quantity of bacterial skin flora - This is a common age-related change; however, it is not directly related to the course of treatment for a sacral pressure ulcer. Proper wound care can mitigate the impact of changes in skin flora.

C. Increased time required for wound healing - Aging often leads to a decline in the body's ability to repair and regenerate tissues, which can prolong the healing process of wounds, including pressure ulcers. Older adults may experience delayed wound healing compared to younger individuals.

D. Increased elasticity of the skin - Skin elasticity decreases with age, making older adults more susceptible to skin breakdown and pressure ulcers due to reduced skin resilience and ability to redistribute pressure. Increased elasticity would not affect the course of treatment positively but rather negatively in this context.

A. Remove heel boots:
Heel boots are often used to protect the heels from pressure ulcers. However, it's important to assess the skin regularly and remove heel boots periodically to inspect the skin underneath. Leaving them on continuously without proper inspection can cause moisture buildup, leading to skin breakdown.

B. Reposition every 3 hours
Repositioning the client every 3 hours is a crucial intervention to prevent skin breakdown, especially in individuals at risk, such as older adults. Prolonged pressure on specific areas of the body can lead to pressure ulcers or bedsores. Regular repositioning helps relieve pressure on vulnerable areas, improving circulation and reducing the risk of skin breakdown.

C. Apply cornstarch to keep the skin dry:
While it's essential to keep the skin clean and dry, using cornstarch can sometimes lead to moisture retention, especially in skin folds. Excess moisture can contribute to skin breakdown and fungal infections. Instead, proper hygiene practices and the use of moisture-wicking products are recommended.

D. Provide high protein diet:
Adequate nutrition, including a high-protein diet, is essential for overall skin health and healing. Protein is necessary for tissue repair and regeneration. While a balanced diet is crucial for overall health, it is not a specific intervention solely focused on maintaining skin integrity.
