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 22 1 out of 1 points Several months of treatment with a statin accompanied by lifestyle modifications have failed to appreciably improve a patient's cholesterol levels. Consequently, the patient has been prescribed cholestyramine. The nurse should recognize that this drugs achieves its therapeutic effect by Response Feedback : Unlike statins, which work by decreasing the synthesis of cholesterol, the bile acid sequestrants such as cholestyramine promote the oxidation of cholesterol to bile acids. Bile acid sequestrants do not promote vasodilation or bind HDL to LDL. Question 23 1 out of 1 points A patient is brought to the emergency department in hypertensive crisis. Nitroprusside is administered intravenously. The patient experiences diaphoresis and dizziness. Which of the following is the appropriate action by the nurse? Response Feedback : Administering nitroprusside too quickly can result in abdominal pain, apprehension, diaphoresis, dizziness, headache, muscle twitching, nausea, palpitations, restlessness, retching, and retrosternal discomfort. The nurse should quickly inform the prescriber and slow the infusion. Symptoms quickly subside when the nitroprusside infusion is slowed or stopped, and usually do not return when the
infusion resumes at a slower rate. Consulting the prescriber for a dose change would not help; the rate of drug administration is the issue. Continuing to give the nitroprusside at the ordered rate could be fatal. Question 24 0 out of 1 points A nurse is providing patient education to a 35-year-old man who has been prescribed clonidine (Catapres) as part of step 2 antihypertensive therapy. The nurse should anticipate that the drug will be administered Response Feedback: Clonidine may be administered orally or parenterally but is most frequently administered transdermally. Question 25 1 out of 1 points A 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? Response 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.
