Question 1 of 5
An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?
Correct Answer: C
Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate.
Therefore, a cardiac output of 5 L/min is considered normal.
Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information.
Choice D is unrelated to the client's cardiac output and thus incorrect.
