B) Albuterol - Albuterol is not a contraindication for sildenafil use.

C) Nitroglycerin - Sildenafil and nitroglycerin both cause vasodilation, and concurrent use can lead to severe hypotension, making nitroglycerin a contraindication for sildenafil use.

Correct Answer is ["500"]

Explanation

To calculate the dosage of erythromycin to be administered every 6 hours, one must first convert the total daily dose from grams to milligrams. There are 1000 milligrams in a gram, so 2 grams is equivalent to 2000 milligrams. Since the medication is to be given in four equally divided doses over 24 hours, the 2000 milligrams should be divided by 4.

Therefore, the nurse should administer 500 milligrams per dose.
