A client has a slight shift to the left on the oxygen-hemoglobin dissociation curve. Which of the following assessment findings will support this curve configuration?

Question

Quizplus · Accepted Answer

A left shift in the oxygen-hemoglobin dissociation curve indicates an increased affinity of hemoglobin for oxygen, meaning oxygen is more tightly bound to hemoglobin and less readily released to tissues. Hypothermia (D) can cause a left shift because lower temperatures increase the affinity of hemoglobin for oxygen. Conditions like alkalosis (pH greater than 7.45, not less as in A), decreased levels of 2,3-diphosphoglycerate (not increased levels as in B), and hypothermia are associated with a leftward shift. Hyperthermia (C) would cause a right shift, indicating decreased affinity of hemoglobin for oxygen, facilitating oxygen release to tissues.
