During an assessment the nurse performs the action shown in this image. What is the purpose of this action?
Measure nerve function in the fingers
Monitor oxygen status
Determine capillary refill
Assess finger range of motion
The Correct Answer is C
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.

Correct Answer is C
Explanation
A. Nail Beds:
While peripheral cyanosis can cause bluish discoloration of the nail beds, central cyanosis is more indicative of systemic hypoxemia and is best assessed in areas with rich blood supply, such as the oral mucosa.
B. Sclera:
The sclera is more commonly used to assess for jaundice (yellowing) rather than cyanosis. Cyanosis is not typically visible in the sclera.
C. Oral Mucosa:
Central cyanosis is most accurately assessed in areas with high vascularization, such as the oral mucosa. This area provides a clear indication of oxygenation status and can reveal hypoxemia more reliably than peripheral sites.
D. Palms:
Similar to the nail beds, the palms can show signs of peripheral cyanosis but are not the primary site for assessing central cyanosis. The oral mucosa remains the best site for this assessment.
Correct Answer is A
Explanation
A) Presbyopia: Presbyopia is an age-related condition where the lens of the eye loses elasticity, making it harder to focus on close objects. This condition typically begins to affect individuals around the age of 40, causing them to hold reading materials farther away to see them clearly. The client's complaint aligns perfectly with this common symptom of presbyopia.
B) Cataracts: Cataracts involve the clouding of the eye's lens, leading to overall blurry vision, glare, and difficulty with night vision. Although cataracts can interfere with reading, they do not specifically cause the need to hold reading materials farther away, which is more indicative of presbyopia.
C) Tropia: Tropia is a type of strabismus where one eye deviates from normal alignment, leading to symptoms like double vision or eye strain. This condition affects how the eyes coordinate but does not typically cause the specific symptom of needing to hold reading materials farther away.
D) Myopia: Myopia, or nearsightedness, results in clear vision for close objects but blurry vision for distant objects. The client's issue of needing to hold reading materials farther away to see clearly is inconsistent with myopia, which would cause difficulty with distant vision instead.
