Serum digoxin levels are monitored for potential toxicity. Monitoring should occur:
 
  1. Within 6 hours of the last dose
  2. Because a reference point is needed in adjusting a dose
  3. After three half-lives from the starting of the drug
  4. When a patient has stable renal function

Question 2

  2. Not increased over the usual dosage for an adult
  3. Given once daily because of memory issues in the older adult
  4. Withheld if she experiences gastroesophageal reflux
