A nurse is preparing to administer a medication known to increase preload. Which is the expected outcome for this client?
 
  1. A reduced stroke volume
  2. An increase in cardiac output
  3. Decreased venous return to the heart
  4. Increased resistance against the left ventricle

Question 2

The nurse is caring for a client with a stroke volume of 54 mL/beat and a heart rate of 72 beats per minute. The nurse calculates that the client's cardiac output is ___ L/min.
 
  Standard Text: Round answer to the nearest tenth.
  What will be an ideal response?

Answer to Question 1

Correct Answer: 2
Rationale 1: An increased preload will not result in a reduced stroke volume in a normal heart.
Rationale 2: Drugs that increase preload generally increase cardiac output.
Rationale 3: Drugs that increase preload generally increase venous return to the heart.
Rationale 4: Preload is the degree to which the ventricles are filled with blood. Afterload is the resistance against the left ventricle.
Global Rationale: Drugs that increase preload generally increase cardiac output. An increased preload will not result in a reduced stroke volume in a normal heart. Drugs that increase preload generally increase venous return to the heart. Preload is the degree to which the ventricles are filled with blood. Afterload is the resistance against the left ventricle.

Answer to Question 2

Correct Answer: 3.9
Rationale: A client's cardiac output is calculated by stroke volume  heart rate.
Global Rationale: A client's cardiac output is calculated by stroke volume  heart rate.
