What should the nurse expect to administer immediately after administering sublingual nitroglycerin (Nitrostat)?

Acetaminophen (tylenol). In the early stages of therapy, nitoglycerin commonly causes headache and dizziness. Acetaminophen usually helps decrease nitroglycerin-induced headaches. Although, the client may be anxious, lorazepam usually isn't given after nitroglycerin. There is no indication that the client would need insulin or prednisone.
