Final answer:
The correct diagnostic test result indicating client progress in pressure ulcer management and effective health care team collaboration is an increased level of serum albumin. It suggests improved nutritional status and the body's ability to heal tissues.
Step-by-step explanation:
The nurse is assessing the effectiveness of interventions for pressure ulcer management. An important indicator of patient progress and effective health care team collaboration in this context is the improvement in nutritional status, represented by the level of serum albumin.
When serum albumin levels increase, it often suggests an improved nutritional state, which is critical for wound healing and recovery.
Serum albumin is a protein made by the liver, and its levels in the blood reflect the body's protein stores and overall nutritional status. Improved albumin levels indicate that the body is better equipped to repair tissues, including healing pressure ulcers.
In contrast, calcium levels are not directly related to pressure ulcer healing; hematocrit reflects the concentration of red blood cells in the blood and is not a direct measure of nutritional status or wound healing.
An increase in the number of immature white blood cells (WBCs) typically indicates an infection or some forms of leukemia, rather than improvement in pressure ulcer management. Therefore, the correct answer is D. serum albumin.
