CorrectoDiureticsDiuretic administration is one factor that increases a patient’s riskfor hypovolemic hyponatremia.CorrectoEmesisEmesis is one factor that increases a patient’s risk forhypovolemic hyponatremia.CorrectoDiarrheaDiarrhea is one factor that increases a patient’s risk forhypovolemic hyponatremia.oDehydrationDehydration increases a patient’s risk for water depletionhypernatremia, not hypovolemic hyponatremia.oFeverInsensible loss of water due to fever increases a patient’s risk forwater depletion, not hypovolemic hyponatremia.Question 4 of 20Which data should the nurse identify as placing apatient at risk for hypovolemic hyponatremia?Correct oProfuse diaphoresisProfuse diaphoresis is a risk factor for hypovolemichyponatremia.oWater intoxicationWater intoxication is a risk factor for hypervolemic, nothypovolemic, hyponatremia.oHypotonic IV solutionHypotonic IV solution administration is a risk factor forhypervolemic, not hypovolemic, hyponatremia.oExcess fluid intakeExcess fluid intake is a risk factor for hypervolemic, nothypovolemic, hyponatremia.Question 5 of 20Which disease process should the nurse identify as thecause of the patient’s serum potassium concentration of5.3 mEq/L?oAnorexiaAnorexia can cause hypokalemia, not hyperkalemia.oAlcoholismAlcoholism can cause hypokalemia, not hyperkalemia.oHyperaldosteronism Hyperaldosteronism can cause hypokalemia, not hyperkalemia.CorrectoSevere infectionsSevere infections, causing the release of intracellular potassium,are a cause of hyperkalemia.

Which cues would a nurse expect in a patient with a serum potassium concentration of 3.1 mEq L?The nurse should expect that a patient with a serum potassium concentration of 3.1 mEq/L would have which clinical manifestation? A serum potassium concentration of 3.1 mEq/L indicates hypokalemia. Hyperactive deep tendon reflexes are associated with hypocalcemia and hypomagnesemia, not hypokalemia.
Which serum potassium concentrations would the nurse identify as hyperkalemia in the patient's medical record?Alterations of Electrolyte Balance. Which factor would the nurse identify as a primary cause of hypocalcemia?The most common cause of hypocalcemia is hypoparathyroidism, which occurs when the body secretes a less-than-average amount of parathyroid hormone (PTH). Low PTH levels lead to low calcium levels in your body.
