The nurse is reviewing the health problems for a group of assigned patients. Which patient does the nurse recognize as being at increased risk for developing metabolic alkalosis?
Patient with bulimia.
Patient with COPD.
Patient with venous stasis ulcer.
Patient on dialysis.
The Correct Answer is A
Choice A rationale: Patients with bulimia are at increased risk for developing metabolic alkalosis due to recurrent vomiting, which leads to loss of hydrochloric acid from the stomach and results in an elevated blood bicarbonate level.
Choice B rationale: Patients with COPD are more likely to develop respiratory acidosis due to retention of carbon dioxide, not metabolic alkalosis.
Choice C rationale: Patients with venous stasis ulcers do not have a direct association with metabolic alkalosis.
Choice D rationale: Patients on dialysis are more likely to experience metabolic acidosis due to impaired kidney function and inability to excrete acid effectively.

Correct Answer is C
Explanation
Choice A rationale:
Sodium level is a laboratory parameter that can be helpful in assessing fluid balance, but it does not directly measure fluid retention. Abnormal sodium levels may indicate fluid imbalances, but it is not the most reliable measure of fluid retention.
Choice B rationale:
Tissue turgor refers to the skin's elasticity, and it can be used to assess dehydration rather than fluid retention. Poor turgor may indicate dehydration, but it does not specifically measure fluid volume increase.
Choice C rationale:
Daily weight is a reliable measure of fluid retention. An increase in weight over a short period may indicate fluid accumulation in the body, while a decrease in weight could signify fluid loss. It is essential to monitor weight consistently under standardized conditions (e.g., same time, same clothing) for accurate assessment.
Choice D rationale:
Intake and output records provide information about fluid intake and output but may not always reflect fluid retention accurately. It is helpful for assessing fluid balance, but daily weight is a more direct and reliable measure of fluid retention.
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.
