A nurse is providing care for a number of older clients on a restorative care unit of a hospital. Many of the clients have diagnoses or histories of hypertension,
 
  and the nurse is responsible for administering a number of medications relevant to blood pressure control. Which of the following assessments would the nurse be most justified in eliminating during a busy morning on the unit?
  A)
  Checking the recent potassium levels of a client receiving an ACE inhibitor
  B)
  Measuring the heart rate of a client who takes a -adrenergic blocker
  C)
  Measuring the pulse of a client taking an ACE inhibitor
  D)
  Noting the sodium and potassium levels of a client who is receiving a diuretic

Question 2

As part of their orientation to a cardiac care unit, a group of recent nursing graduates is receiving a refresher in cardiac physiology from the unit educator.
 
  Which of the following teaching points best captures a component of cardiac function?
  A)
  Efficient heart function requires that the ventricles do not retain any blood at the end of the cardiac cycle.
  B)
  Recall that the heart sounds that we listen to as part of our assessments are the sounds of the myocardium contracting.
  C)
  The diastolic phase is characterized by relaxation of ventricles and their filling with blood.
  D)
  Aortic pressure will exceed ventricular pressure during systole.

Answer to Question 1

Ans:
C

Feedback:

ACE inhibitors act on the renin-angiotensin-aldosterone system and thus do not significantly influence heart rate. They can, however, induce hyperkalemia, and it would be prudent for the nurse to check potassium levels. -adrenergic blockers affect a client's heart rate, and diuretics can affect electrolyte levels.

Answer to Question 2

Ans:
C

Feedback:

Diastole is associated with ventricular filling and relaxation. Cardiac output is not 100 or near to it with each cardiac cycle, and heart sounds are associated with valve closing. Ventricular pressure exceeds that of the aorta during systole.
