A nurse is teaching a group of clients about recommended nutrition for healthy eating. Which of the following instructions should the nurse include in the teaching?

A. Clear-colored urine: Clear-colored urine typically indicates adequate hydration or even overhydration. In Clostridium difficile, where the client may be experiencing profuse diarrhea, clear urine would not align with fluid volume deficit. This finding suggests the kidneys are excreting diluted urine, which is not consistent with dehydration.
B. Decreased urine specific gravity: A decreased urine specific gravity reflects dilute urine and usually points to overhydration or an inability to concentrate urine. In a client with C. difficile and likely diarrhea-related fluid loss, the expected finding would be a concentrated urine with increased specific gravity, not decreased.
C. Increased hematocrit: An increased hematocrit indicates hemoconcentration, which occurs when plasma volume is reduced due to fluid loss. In the setting of Clostridium difficile infection, where fluid is lost rapidly through diarrhea, this rise in hematocrit is a classic marker of fluid volume deficit. It reflects the relative increase in red blood cells due to a lower plasma volume.
D. Hypertension: Hypertension is more commonly associated with fluid volume excess or other cardiovascular conditions. In cases of fluid volume deficit, hypotension or orthostatic hypotension is more expected due to decreased circulating blood volume. Therefore, high blood pressure would not support the diagnosis of dehydration in this context.

A. Has occasional incontinence. Incontinence increases moisture exposure and contributes to skin breakdown risk, but "occasional" incontinence presents a moderate rather than the highest level of risk. Consistent exposure would be more concerning.
B. Eats one serving of protein per day. Inadequate protein intake significantly impairs tissue repair and skin integrity, placing the client at the highest risk for pressure injuries. Protein is essential for maintaining skin health and supporting the healing process.
C. Responds to verbal commands. This indicates that the client is alert and cognitively intact, allowing for active participation in repositioning and care, which lowers the risk for skin breakdown.
D. Is able to walk short distances. Some level of mobility helps relieve pressure and promotes circulation, both of which reduce the likelihood of pressure injury development. Limited mobility presents less risk than poor nutritional intake.
