A nurse is collecting data about the fluid status of four clients. Which of the following clients should the nurse identify as being at risk for fluid volume deficit?

The correct answer is B: A client who has heart failure and is receiving diuretic therapy. In heart failure, the heart's ability to pump blood effectively is compromised, leading to fluid retention. Diuretics are prescribed to reduce fluid overload by increasing urine output. This process can potentially lead to fluid volume deficit if excessive fluid is removed. Clients with heart failure on diuretics are at risk for electrolyte imbalances and dehydration.
A: NPO status for an endoscopy does not necessarily indicate fluid volume deficit.
C: Clients with end-stage kidney disease undergoing dialysis are at risk for fluid volume overload due to the accumulation of waste products and fluid in the body.
D: Clients with gastroenteritis receiving oral fluids are typically at risk for fluid volume deficit, but the scenario does not provide enough information to confirm this as the correct choice.
In summary, choice B is correct because clients with heart failure on diuretics are at risk for fluid volume deficit due to the medication
