Question 1 of 5
A nurse who is mentoring a graduate nurse explains the correlation between severe blood loss and the effect on the client's mean arterial pressure (MAP). The graduate nurse demonstrates correct understanding when he states which of the following:
Correct Answer: D
Rationale: The correct answer is D: Lower blood volume lowers MAP. Mean Arterial Pressure (MAP) is determined by cardiac output and systemic vascular resistance. Severe blood loss results in decreased blood volume, leading to a decrease in cardiac output. With lower cardiac output, there is less blood being pumped into the arteries, resulting in lower pressure exerted on the arterial walls, hence lowering the MAP.
Choices A and B are incorrect as severe blood loss reduces cardiac output and would not raise it or cause vasoconstriction.
Choice C is incorrect as there is a direct correlation between blood loss and MAP.
