discuss his recent erectile dysfunction (ED) and has requested a prescription for tadalafil (Cialis) based on television commercials he has seen. What characteristic of this patient would most likely contraindicate the use of tadalafil for his ED? Response Feedback: Like the other drugs in this class, tadalafil should not be taken within 48 hours of taking nitrates, such as nitroglycerin, because substantially lower blood pressure and possibly death may result. Nitroglycerin use is a contraindication for taking tadalafil, as it is for all drugs in this class. Allopurinol, ginseng, and low bone density do not contraindicate the use of tadalafil. Question 15 1 out of 1 points A nurse is working with a patient in the clinic who has erectile dysfunction. The patient has been prescribed sildenafil (Viagra). The patient wants to do everything he can to promote effectiveness of the drug. The nurse will instruct him to Response Feedback: Maximum plasma concentrations of sildenafil are reached within 30 to 120 minutes of oral dosing when taken on an empty stomach. The most frequent peak time is 60 minutes. However, when the drug is taken with a high-fat meal, absorption is slow and 60 extra minutes are needed to reach peak plasma levels. A high-fat meal reduces peak serum concentrations by 29%. Therefore, the patient should be advised to avoid high-fat meals when ingesting the drug. Avoiding a high-protein meal or drinking fluids will not help achieve quick effects from the drug. It is not advisable to increase the dosage of the drug without consulting the prescriber. Question 16 1 out of 1 points A nurse is providing patient education to a 23-year-old woman who is starting the norelgestromin/ethinyl estradiol transdermal system (Ortho Evra). Because this is the patient's first time to use the birth control patch, the nurse will instruct her to apply the patch Response Feedback : The first time a woman uses the norelgestromin/ethinyl estradiol transdermal system, she should start it after her menstrual period begins. She can choose to apply the first patch either the day her period starts or the following Sunday. If she chooses the Sunday after the start of her period, she needs to use backup contraception for the first week of her first cycle. Question 17 1 out of 1 points

A patient is taking flavoxate hydrochloride (Urispas) to help control an overactive bladder. On a follow-up visit to the clinic, the nurse will question the patient about which of the following? Response Feedback: Because a prominent anticholinergic effect is dry mouth, good oral hygiene is very important to prevent dental caries and gum disorders. Dryness may be relieved with hard candies, chewing gum, or lip gloss. Chronic diarrhea, headaches, and a special diet are not issues with this drug.
