Question 21 out of 1 pointsA nurse who provides care in a busy clinic is aware of the high incidence and prevalence of hyperlipidemia and the consequent need for antihyperlipidemics in many patients. Treatment of high cholesterol using statins would be contraindicated in which of the following patients? An obese male patient who is a heavy alcohol user and who has cirrhosis of the liverResponse Feedback:Active liver disease is a contraindication to the use of statins. As well, heavy alcohol use increases the risk of liver dysfunction. Respiratory disease, recent surgery, and organic cognitive deficits do not preclude the use of statins for high cholesterol.Question 31 out of 1 pointsA 77-year-old man's chronic heart failure is being treated with a regimen of quinapril (Accupril) and furosemide (Lasix). Which of the following assessment findings would suggest that the loop diuretic is contributing to a therapeutic effect? The man’s chest sounds are clear and his ankle edema is lessened.Response Feedback:Appropriate diuretic therapy leads to the resolution of pulmonary and peripheral edema. Healthy kidney function, cardiac rhythm, and electrolyte levels are all desirable outcomes, but they are not directly indicative of the therapeutic action of diuretics in the treatment of CHF.
Question 41 out of 1 pointsA patient with class-IV CHF has a medication regimen consisting of metoprolol (Lopressor), enalapril (Vasotec), and furosemide (Lasix). In addition to regularly assessing the patient s heart rate, the nurse should prioritize assessment of the patient's blood pressureResponse Feedback:Fluid balance, cognition, and exercise tolerance are all affected by CHF and should be regularly assessed as part of thorough nursing care. However, the combination of an ACE inhibitor, a beta blocker, and a diuretic constitutes a significant risk for hypotension and indicates a need for frequent blood pressure monitoring.Question 51 out of 1 pointsA patient has recently been prescribed a drug that treats his hypertension by blocking the sympathetic receptors in his sympathetic nervous system. This action is characteristic of adrenergic antagonistResponse Feedback:Those drugs that stimulate sympathetic receptors are referred to as adrenergic or dopaminergic agonists (stimulators) and those that block are referred to as adrenergic antagonists (blockers). Adrenergic antagonism is not synonymous with the action of a cardiotonic drug.Question 61 out of 1 pointsA patient is diagnosed with heart failure and is started on digoxin. On the second day of therapy, lab values, the ECG results, and the patient's symptoms indicate that the medication is not producing a therapeutic effect. An appropriate nursing action would be to continue to administer the med
Response Feedback:The nurse should continue regular administration of the drug because digoxin requires a loading dose before the drug's therapeutic effect is present. It may take several days for optimal clinical effects to appear. Therefore, seeking an order to
