A child with cool extremities, thready pulses, and diminished urinary output
Question 1 of 5
The nurse is assessing a child with a cardiac problem. The child's extremities are cool with thready pulses, and urinary output is diminished. This is most suggestive of which of the following?
Correct Answer: B
Rationale: The correct answer is B: Decreased cardiac output. Cool extremities, thready pulses, and diminished urinary output are signs of poor tissue perfusion, indicating decreased cardiac output. Cardiac output is the amount of blood pumped by the heart per minute, and when it decreases, perfusion to tissues is compromised. This can lead to the observed symptoms. Increased afterload (
A) would typically present with increased blood pressure and systemic vascular resistance. Decreased contractility (
C) would present with weak pulses and poor cardiac output. Increased stroke volume (
D) would not manifest as cool extremities and diminished urinary output.
