The nurse would immediately collaborate with the health care provider if a patient experiences a "shift to the left" in laboratory values. What is the rationale for this collaboration?
1. This shift is an indicator of electrolyte imbalance.
2. This shift is an indicator of disruption of hemostasis.
3. This shift is an indicator of a potential bleeding problem.
4. This shift is an indicator of risk for a severe infection.
4
Rationale 1: A "shift to the left" does not pertain to electrolyte imbalance.
Rationale 2: A "shift to the left" does not pertain to hemostasis disruption.
Rationale 3: A "shift to the left" does not pertain to potential bleeding problems.
Rationale 4: In a "shift to the left," the bone marrow is stimulated to release a large number of relatively immature and juvenile cells as a compensatory mechanism to combat severe infection. In an otherwise healthy individual, this may signal an early sign of an otherwise undetected infection, and the patient may not have sufficient host defenses.
