Answer #1

a) There can be two reasons for the low potassium level.

  • NPO: Nothing by mouth (NPO) means that Mrs. Dean has not been taking oral food. This might lead to low potassium level.
  • Furosemide: This is a diuretic which results in potassium loss. So this also can cause low potassium level.

b) The nurse should inform the doctor about the low potassium level and suggest to administer potassium.

c) The nurse should asses the following clinical manifestation.

  • Nausea
  • Vomitting
  • Leg cramps
  • Fatigue and muscle weakness
  • Hypoactive reflexes
  • Polyuria
  • Abdominal distention
