with the bile acids in the intestine to make them nonresorbable. The bile acids are then eliminated in the stool. Because of this mechanism of action, the drug should be administered before a meal. Question 5 1 out of 1 points A nurse is caring for a patient who is taking digoxin and a loop diuretic. Which of the following would be most important for the nurse to monitor? Response Feedback : Although it is important to monitor the patient's ECG, it is more important to closely monitor potassium levels when the patient is taking a drug that promotes the loss of potassium, such as thiazide or loop diuretics. Hypokalemia increases the effect of digoxin and increases the risk for digoxin toxicity. The patient's sodium levels and liver enzyme levels may need to be monitored periodically, but not as closely as potassium levels. Question 6 1 out of 1 points A 45-year-old man who is a construction worker has been diagnosed with hyperlipidemia and has been prescribed lovastatin. The nurse will advise the patient to Response Feedback : Since the patient works outdoors most of the time, the nurse should advise him to avoid prolonged exposure to sunlight by wearing protective gear. Advising the patient regarding the use of OTC drugs and drug changes would be better handled by the prescriber. The patient should not drink moderate amounts of alcohol, but should avoid alcohol altogether while taking lovastatin. Question 7 1 out of 1 points A 77-year-old patient has a long-standing history of hypertension, a health problem that is being treated with metoprolol and a thiazide diuretic. Before administering the 8 AM dose of these medications, what
assessments should the nurse perform and document? (Select all that apply.) Response Feedback : Because of its effects on blocking beta-1 receptors, metoprolol slows the heart rate, the speed of conduction, and decreases the force of contraction, thus cardiac output is decreased, decreasing blood pressure. Consequently, it is necessary to assess the patient's heart rate in addition to his or her blood pressure. Neither beta blockers nor thiazide diuretics create a direct need for the assessment of temperature, respiratory rate, or oxygen saturation level. Question 8 1 out of 1 points A nurse explains to a patient that nitroglycerin patches should be applied in the morning and removed in the evening. This medication schedule reduces the potential for Response Feedback : The nurse will stress that it is important to remove the patch for 10 to 12 hours every 24 hours to prevent nitrate tolerance from developing. If anginal symptoms develop at night, the use of a beta blocker or calcium channel blocker should be considered. Patients who normally have angina only during daytime hours are not at substantial risk for developing nighttime angina with a nightly nitrate-free period. Applying the nitroglycerin patch in the morning and removing it in the evening would not significantly limit the adverse effects from the drug.
