The patch should stay in place for 7 days before replacement. Question 33 1 out of 1 points A nurse is discussing with a 58-year-old male patient the causes of erectile dysfunction in men over 50 years of age. Which of the following will the nurse inform the patient is the primary physical cause of erectile dysfunction of men in this age group? Response Feedback: Vascular disease is the most common physical cause of erectile dysfunction. Atherosclerosis of the penile artery is the primary cause of erectile dysfunction in more than half of men over age 50. Men with diabetes are more prone to erectile dysfunction because of a combination of vascular disease and neuropathy. A decrease in testosterone levels is not a common cause of erectile dysfunction. Emotional stress is not a physical factor. Question 34 1 out of 1 points A nurse is instructing a 19-year-old female patient on the use of fluconazole for candida vaginitis. A teaching priority will be to
Response Feedback: A teaching priority would be to tell the patient to use another form of birth control if she was taking an oral contraceptive. Fluconazole may decrease the effectiveness of oral contraceptives. Taking an antiemetic or antidiarrheal for adverse GI effects would be an appropriate instruction for this drug. The nurse should also instruct the patient to take aspirin instead of acetaminophen for relief of minor discomforts because acetaminophen has the potential to damage the liver and kidneys. Taking the drug with food is recommended if the patient experiences GI distress. All of these instructions are important, but not as important as making sure that the patient does not inadvertently become pregnant while on the medication. Question 35 1 out of 1 points A pregnant patient who has diabetes has been admitted to the hospital to begin labor. Since the patient has diabetes, the physician has decided to use oxytocin (Pitocin) to initiate labor contractions. When talking to the patient about the adverse effects of the drug, the nurse should understand that the most common adverse effects of the drug include Response Feedback: Adverse effects of oxytocin are dose related and take two forms—maternal and fetal. The most common maternal adverse effects are nausea, vomiting, uterine tachysystole, and cardiac arrhythmias. Less common but potentially fatal are severe water intoxication and hyponatremia. Question 36 1 out of 1 points A nurse is providing patient education to a 50-year-old woman who is taking methotrexate (MTX) for breast cancer. The nurse will instruct the patient to avoid which of the following drugs? Response Feedback: Because MTX is secreted by the renal tubules, certain drugs that follow the same pathway, such as salicylates, sulfonamides, phenytoin, and penicillin, may compete with MTX excretion, resulting in accumulation and increased toxicity. Therefore, if these drugs cannot be avoided, they should be discontinued 2 days before and restarted 2 days after MTX therapy.
