Week 3 Quiz
Question 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
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
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).
