A nurse is assessing a client who has fluid volume deficit. The nurse should expect which of the following findings?
Increased urine ketones.
Decreased Hgb.
Decreased urine specific gravity.
Increased BUN.
The Correct Answer is D
Choice A rationale:
Increased urine ketones are not indicative of fluid volume deficit. Instead, they may suggest diabetic ketoacidosis or starvation ketosis.
Choice B rationale:
Decreased Hgb (hemoglobin) is not specific to fluid volume deficit and can be seen in various conditions such as anemia or bleeding.
Choice C rationale:
Decreased urine specific gravity is not consistent with fluid volume deficit, as it usually results in concentrated urine with increased specific gravity.
Choice D rationale:
An increased blood urea nitrogen (BUN) level is expected in fluid volume deficit due to reduced kidney perfusion and function. BUN is a marker of kidney function and is elevated when fluid volume is low.

Correct Answer is B
Explanation
Choice A rationale:
A phosphorus level of 4.5 mEq/L falls within the normal range, which is typically between 2.5 to 4.5 mEq/L. Although it's essential to monitor phosphorus levels, it is not the priority finding in this scenario.
Choice B rationale:
A potassium level of 2.9 mEq/L is the priority finding. The normal range for potassium is typically between 3.5 to 5.0 mEq/L. A potassium level of 2.9 mEq/L indicates severe hypokalemia, which can lead to life-threatening cardiac arrhythmias and muscle weakness. Immediate intervention is necessary to address the potassium imbalance.
Choice C rationale:
A calcium level of 8.2 mg/dL falls within the normal range (typically 8.5 to 10.2 mg/dL). While calcium levels are essential to monitor, they do not take precedence over the critically low potassium level in this situation.
Choice D rationale:
A sodium level of 145 mEq/L falls within the normal range, which is usually around 135 to 145 mEq/L. Although monitoring sodium levels is important, it is not the priority finding when compared to the critically low potassium level.
Correct Answer is D
Explanation
The correct answer is choice D: Reduction of T-wave amplitude.
Choice A rationale:
The amplitude of the QRS complex is not directly affected by changes in serum potassium levels. It represents ventricular depolarization, and its restoration would not be an expected outcome of polystyrene sulfonate treatment
Choice B rationale:
Shortening of the P-wave duration is not an expected change with polystyrene sulfonate treatment. The P-wave represents atrial depolarization, which is not significantly impacted by the administration of this medication
Choice C rationale:
Widening of the QRS complex is associated with high serum potassium levels. The goal of polystyrene sulfonate treatment is to lower potassium levels and, thus, return the QRS complex to its normal width
Choice D rationale:
Polystyrene sulfonate aims to reduce serum potassium levels. When effective, this should result in a reduction of T-wave amplitude, which is a common ECG change seen with hyperkalemia
In conclusion, choice D is the correct answer, as a reduction in T-wave amplitude would be the expected change on the client's ECG if polystyrene sulfonate effectively lowers their serum potassium level.
