A patient, with a history of heart failure, is admitted with dehydration, malnutrition, and fatigue. The nurse learns that the patient has been taking multiple doses of a thiazide diuretic
Which of the following electrolyte disorders should be investigated for this patient? 1. hypocalcemia
2. hypophosphatemia
3. hypernatremia
4. hypermagnesemia
2
Rationale: Hypophosphatemia is associated with malnourished states and is a relatively common imbalance in the high acuity patient. Other conditions that can cause hypophosphatemia include those disorders that cause hypercalcemia. Thiazide diuretics can cause hypercalcemia. The patient was found to be taking multiple doses of a thiazide diuretic. Therefore, the patient's phosphorus level should be evaluated. Hypophosphatemia is also associated with muscle fatigue, another symptom that the patient is demonstrating. Dehydration, malnutrition, and fatigue are not directly linked to hypocalcemia, hypernatremia, or hypermagnesemia.
