Final answer:
An older adult is diagnosed with congestive heart failure and pulmonary edema, and the primary health-care provider prescribed furosemide 40mg PO twice a day, the number milliliters the nurse administer is 5mL
Step-by-step explanation:
To calculate the number of milliliters of furosemide that the nurse should administer, we can use the equation:
number of milliliters = total dosage in milligrams / concentration in milligrams per milliliter
In this case, the total dosage is 40mg, and the concentration is 8mg/mL. Plugging these values into the equation, we get:
number of milliliters = 40mg / 8mg/mL = 5mL
Therefore, the nurse should administer 5 milliliters of the oral solution of furosemide to the patient.
