A nurse is reviewing the laboratory results of a client who has fluid volume deficit. The nurse would expect which of the following findings?

Urine specific gravity 1.035.

BUN 19 mg/dL.

Hematocrit 44.9%.

Sodium 155 mEq/L.

Answer and Explanation

The Correct Answer is A

Sodium 155 mEq/L. Choice A rationale:

A urine specific gravity of 1.035 indicates concentrated urine and is consistent with fluid volume deficit. However, it is not the most specific finding for this condition.

Choice B rationale:

A BUN (blood urea nitrogen) level of 19 mg/dL can be a normal value. It is within the reference range (usually around 7-20 mg/dL) and does not provide specific information about fluid volume deficit.

Choice C rationale:

A hematocrit of 44.9% can also be within the normal range for some individuals, and while it can be elevated in cases of fluid volume deficit, it is not as sensitive as other parameters for detecting this condition.

Choice D rationale:
This is the correct answer because a sodium level of 155 mEq/L is elevated and indicates hypernatremia, which is associated with fluid volume deficit. Hypernatremia occurs when there is a relative lack of water in relation to the sodium concentration in the blood, and it can lead to dehydration

Correct Answer is B

Explanation

Choice B rationale:

The patient's tachycardia, pale, cool skin, and decreased urine output are signs of the body's natural compensatory mechanisms in response to fluid volume deficit. When the body

experiences a decrease in fluid volume, it tries to compensate by increasing heart rate (tachycardia) to maintain blood flow to vital organs and constricting blood vessels to preserve fluid and maintain blood pressure. Pale, cool skin is a result of vasoconstriction, and decreased urine output is a way the body conserves water during dehydration.

Choice A rationale:

Effects of rapidly infused intravenous fluids are not the cause of the patient's current findings. In fact, the nurse's notes indicate that the IV fluid therapy (0.9% sodium chloride) was initiated at 125 mL/hr, which is a relatively standard and cautious rate. Rapidly infused fluids could potentially cause fluid overload, but that is not the situation here.

Choice C rationale:

Pharmacological effects of a diuretic are not relevant to this patient's presentation. There is no mention of diuretic use in the nurse's notes, and the symptoms presented are more consistent with fluid volume deficit and dehydration rather than diuretic use.

Choice D rationale:

Cardiac failure is not the correct answer, as there is no indication of heart failure in the patient's presentation or nurse's notes. The symptoms and findings described are more indicative of fluid volume deficit, which is not synonymous with cardiac failure.

A. Administering a potassium-sparing diuretic. B. Administering sodium polystyrene sulfonate. C. Initiating an IV potassium infusion. D. Encouraging the client to eat bananas.

Correct Answer is B

Explanation

The correct answer is choice B) Administering sodium polystyrene sulfonate.

Choice A rationale:

Administering a potassium-sparing diuretic is not appropriate for a client with hyperkalemia (high potassium levels). Potassium-sparing diuretics would further increase potassium levels, worsening the condition.

Choice B rationale:

Sodium polystyrene sulfonate is used to treat hyperkalemia. It works by exchanging sodium ions for potassium ions in the intestines, which helps to lower serum potassium levels by excreting it through the stool.

Choice C rationale:

Initiating an IV potassium infusion would be contraindicated in this situation as it would increase the already elevated potassium levels, potentially leading to dangerous cardiac complications.

Choice D rationale:

Encouraging the client to eat bananas is not advisable because bananas are high in potassium, which would exacerbate hyperkalemia.
