While working in the Emergency department a Rapid response nurse is evaluating a patient in acute respiratory failure after a motor vehicle crash. Which of the following areas should the nurse evaluate as the most reliable indicator of central cyanosis?

A) Eye turning inward:

Esotropia is a condition where one or both eyes turn inward, leading to misalignment. This inward turning can cause double vision, depth perception issues, and sometimes amblyopia (lazy eye) if not treated early. This is the primary characteristic that defines esotropia.

B) Eye malalignment:

While eye malalignment is a general term that can describe conditions like esotropia, exotropia, or hypertropia, it does not specify the direction of the misalignment. Esotropia specifically refers to inward turning of the eye, which is a more precise description of the condition.

C) Eye oscillating:

Eye oscillation refers to nystagmus, which is a condition characterized by repetitive, uncontrolled movements of the eyes, often resulting in reduced vision. Nystagmus is not related to esotropia, which involves inward turning rather than oscillation.

D) Eye turning outward:

Eye turning outward is known as exotropia, which is the opposite of esotropia. Exotropia involves the eyes turning away from the nose, whereas esotropia involves the eyes turning towards the nose. These are distinct conditions with different clinical presentations.

A. Measure nerve function in the fingers:

Measuring nerve function typically involves different assessments, such as checking sensation or performing nerve conduction studies. The action in the image is not indicative of a nerve function test.

B. Monitor oxygen status:

Monitoring oxygen status is usually done with a pulse oximeter, which is placed on the finger but does not involve the manual action shown in the image. The image depicts a manual technique, not a pulse oximetry procedure.

C. Determine capillary refill:

The action shown in the image is a technique used to determine capillary refill time. The nurse presses on the nail bed until it blanches and then releases it to see how quickly the color returns. This assesses peripheral perfusion and can indicate circulatory status.

D. Assess finger range of motion:

Assessing finger range of motion involves moving the fingers through their full range of motion, such as flexing, extending, abducting, and adducting them. The action in the image does not reflect these movements and is more indicative of assessing capillary refill.
