A nurse is reviewing the laboratory results of a client who is dehydrated. Which of the following BUN lab values should the nurse report to the provider?

Choice A rationale:

Hypophosphatemia is a condition characterized by low levels of phosphate in the blood, which can be caused by various factors, including malnutrition. In this case, the patient has a history of stomach ulcers, which might have contributed to poor nutrient absorption. The nurse should request a dietitian consult to ensure the patient receives an appropriate diet rich in phosphorus, which is essential for cellular function, bone health, and energy metabolism.

Choice B rationale:

Providing aluminum hydroxide antacids as prescribed is not the appropriate intervention for hypophosphatemia. Aluminum hydroxide antacids can bind to phosphate in the gastrointestinal tract, reducing its absorption and potentially worsening the patient's already low phosphate levels.

Choice C rationale:

Instructing the patient to avoid poultry, peanuts, and seeds is not suitable for this situation. These foods are good sources of phosphorus, and avoiding them would further deplete the patient's already low phosphate levels.

Choice D rationale:

Instructing the patient to avoid the intake of sodium phosphate is not necessary for hypophosphatemia. While sodium phosphate preparations are used as laxatives, there is no indication that the patient is taking them, and they are not relevant to the management of hypophosphatemia.

The correct answer is choice D. The client who has gastroenteritis and is febrile.

Choice A rationale:

The client with end-stage renal failure scheduled for dialysis would not be at risk for fluid volume deficit because dialysis is a treatment that removes waste, salt, and extra water to prevent them from building up in the body, keeping a safe level of certain chemicals in the blood, and controlling blood pressure.

Choice B rationale:

Being NPO (nothing by mouth) since midnight for endoscopy typically involves a short period of fasting. While it could potentially contribute to a mild fluid volume deficit, it is not as significant as other causes like vomiting or diarrhea, which can lead to more substantial fluid losses.

Choice C rationale:

A client with left-sided heart failure and an elevated BNP level is more likely to experience fluid volume overload rather than a deficit. BNP is released in response to ventricular volume expansion and pressure overload, which are indicative of heart failure, not fluid volume deficit.

Choice D rationale:

The client with gastroenteritis and a fever is at risk for fluid volume deficit due to increased fluid losses from vomiting, diarrhea, and fever-induced perspiration. These symptoms align with the common risk factors for fluid volume deficit, which include vomiting, diarrhea, and sweating.
