NR 566 Week 3 Discussion and QUIZ {2020} Week 3 Quiz Question 1 1 / 1 pts Diagnosis of heart failure cannot be made by symptoms alone because many disorders share the same symptoms. The most specific and sensitive diagnostic test for heart failure is:    Complete blood count, blood urea nitrogen, and serum electrolytes that facilitate staging for end-organ damage.      Chest x-rays that show cephalization and measure heart size.   Correct!    Two-dimensional echocardiograms that identify structural anomalies and cardiac dysfunction.      Measurement of brain natriuretic peptide to distinguish between systolic and diastolic dysfunction.     Question 2 1 / 1 pts Because primary hypertension has no identifiable cause, treatment is based on interfering with the physiological mechanisms that regulate blood pressure. Thiazide diuretics treat hypertension because they do which of the following? Correct!    Deplete body sodium and reduce fluid volume.      Decrease the production of aldosterone.      Increase renin secretion.      Decrease blood viscosity.     Question 3 1 / 1 pts A patient presents to the clinic with complaint of a persistent, dry and nagging cough that begin shortly after starting lisinopril. What action should the clinician take? Correct!    Discontinue the medication and start losartan (Cozaar).      Discontinue the medication and start clonidine (Catapres).      Continue the medication and refer the patient to a pulmonologist.      Continue the medication and advise the patient that this side effect will resolve in a few weeks.     Question 4 1 / 1 pts Compelling indications for an ACE inhibitor as treatment for hypertension based on clinical trials includes: Correct!    Post myocardial infarction.      Dyslipidemia.      Pregnancy.      Renal calculi.     Question 5 1 / 1 pts One of the three types of heart failure involves systolic dysfunction. Potential causes of this most common form of heart failure include: Correct!    Myocardial ischemia and injury secondary to myocardial infarction.      Inadequate relaxation and loss of muscle fiber secondary to valvular dysfunction.      Increased demands of the heart beyond its ability to adapt secondary to anemia.      Slower filling rate and elevated systolic pressures secondary to uncontrolled hypertension.     Question 6 1 / 1 pts Which of the following medications require monitoring of pulmonary and thyroid function tests every 6 months?    Procainamide (Pronestyl).   Correct!    Amiodarone (Cordarone).      Mexilitine (Mexitil).      Flecainide (Tambocor).
