What clinical signs indicate inadequate fluid volume in a client?

When assessing for signs of inadequate fluid volume, certain indicators, such as dry mucous membranes and poor skin turgor, are critical. Dry mucous membranes suggest that there is not enough moisture in the body's tissues, which is a hallmark symptom of dehydration or fluid deficit. Poor skin turgor, which refers to the skin's elasticity and its ability to return to its normal shape after being pinched, also reflects inadequate hydration. When the body lacks sufficient fluid, the skin can lose elasticity, leading to delayed return or 'tenting' when pinched.

Other options do not align with the clinical signs of inadequate fluid volume. For example, decreased blood pressure is a possible indicator, but moist skin more typically indicates adequate hydration or conditions such as hyperthermia. Increased urine output is often seen in conditions resulting in excess fluid rather than deficit, while normal capillary refill and clear urine suggest the body is adequately hydrated. Thus, the combination of dry mucous membranes and poor skin turgor specifically points to inadequate fluid volume, making it the best choice.
