Question 1 1 out of 1 points A 30-year-old woman who is in the first trimester of pregnancy has presented to her primary care provider with a 4-day history of a reddened, itchy left eye that is crusted with purulent exudate. The clinician suspects a bacterial, rather than viral, etiology. How will the patient's pregnancy affect the potential use of ciprofloxacin to treat her conjunctivitis? Response Feedback: Ciprofloxacin is contraindicated in patients who are pregnant or lactating. Alternative routes and dosages do not mitigate the risks during pregnancy. Question 2 1 out of 1 points A nurse is explaining the use of acyclovir therapy to a 72-year-old man. Nephrotoxicity is discussed as a major adverse effect in older patients. To minimize the risk of the patient developing this adverse effect, the nurse will advise him to Response Feedback : To minimize the risk of developing nephrotoxicity, the patient should stay well hydrated by drinking at least eight 8-oz glasses of water daily. Eating light meals or taking the drug on an empty stomach would not decrease the risk of developing nephrotoxicity. A nurse should never alter the drug dosage without consulting the prescriber. Question 3 1 out of 1 points A nurse is caring for a patient who is on amphotericin B. On morning rounds the patient reports weakness, numbness, and a tingling sensation in his feet. What would be a priority action by the nurse? Response Feedback : For the patient with sensory-perceptual disturbances, such as numbness and a tingling sensation, or weakness, the nurse should make sure that the patient understands the need to ask for assistance when getting out of bed. The patient's bed should be kept low, and the side rails should be kept up at all times. Using aseptic technique is essential to reduce the risk of infection, and increased fluid intake is advised in amphotericin B therapy, but these would not help relieve the patient's symptoms or provide a measure of patient safety. Question 4 1 out of 1 points A patient is prescribed ganciclovir to treat a CMV infection. An oral dosage is prescribed. To help increase bioavailability of the drug, the nurse will encourage the
patient to take the medication Response Feedback : After oral administration, ganciclovir is absorbed poorly from the GI tract. Bioavailability is increased when the medication is administered with a high-fat meal. High-protein meals, orange juice, and an empty stomach will not help increase bioavailability of this drug.
