The nurse administers an IV phosphodiesterase inhibitor. What drug will result in forming a precipitate if given via the same IV line without adequate flushing?
 
  A) Albuterol (Proventil)
  B) Nifedipine (Procardia)
  C) Furosemide (Lasix)
  D) Lovastatin (Mevacor)

Question 2

The nurse receives a new medication order for a patient to administer 240 mg of medication per day in equally divided doses every 6 hours. How many mg of the drug should the nurse administer for each dose?
 
  What will be an ideal response?

Answer to Question 1

C
Feedback:
Furosemide, when given with a phosphodiesterase inhibitor, forms precipitates; therefore, this combination should be avoided. Use alternate lines if both of these drugs are being given IV. There are no known drug-to-drug interactions with albuterol, nifedipine, or lovastatin.

Answer to Question 2

60 mg
Feedback:
Because there are 24 hours in a day, giving a drug every 6 hours would mean giving the drug 4 times a day. Because the total daily dose is 240 mg, dividing that dose by 4 would mean each dose should be 60 mg.
