Answer to Question 2

C

Feedback
A Incorrect. Peripheral cyanosis of the hands is usually caused by instability of the peripheral circulation system typically seen in the young infant and is not a concern. This is called acrocyanosis.
B Incorrect. The nurse will not be most concerned about perioral cyanosis (cyanosis of the skin around the lips).
C Correct. The nurse will be most concerned about cyanosis of the lips or tongue. This finding may indicate a cardiovascular alteration. Cyanosis appears when hemoglobin, approximately 5g/dl of blood, circulates unbound to oxygen and the measured oxygen saturation drops below 85.
D Incorrect. Cyanosis of the feet is usually caused by instability of the peripheral circulation system typically seen in the young infant and is not a concern. This is called acrocyanosis.
