[olgavictoria]

A patient is admitted to the outpatient diagnostic unit for further testing to identify the cause of the uncontrolled secondary hypertension.
 
  In preparation, the nurse should anticipate that which of the following diagnostic procedures will provide the most definitive diagnosis?
  A)
  Routine ultrasound of kidney
  B)
  Renal arteriography
  C)
  Echocardiography
  D)
  Serum creatinine level

Question 2

A nurse is using a stethoscope and blood pressure cuff to manually measure a client's blood pressure. The nurse knows that which of the following facts related to blood flow underlies the ability to hear blood pressure by auscultation (listening)?
 
  A)
  The force of blood with each cardiac contraction produces friction on vessel walls that can be heard and felt.
  B)
  The movement of smooth muscle surrounding vessels produces noise that is audible by a stethoscope.
  C)
  Turbulent flow of blood during systole produces sound while laminar flow during diastole is silent.
  D)
  Pressure pulsation that exceeds the velocity of blood flow is audible and coincides with systolic BP.

Answer to Question 1

Ans:
B

Feedback:

: With the dominant role that the kidney assumes in blood pressure regulation, it is not surprising that the largest single cause of secondary hypertension is renal disease. Renal arteriography remains the definitive test for identifying renal artery disease. Ultrasound, CT, and MRA are other tests that can be used to screen for renovascular hypertension.

Answer to Question 2

Ans:
D

Feedback:

The pressure pulsations that accompany intermittent blood ejection from the ventricles cause sounds that are audible when measuring blood pressure and palpable at pulse sites. Friction, muscle movement, and turbulent blood flow do not account for the pressure pulsations.
