Practice Question

 To determine if a client with darker skin has cyanosis, the nurse should assess the color in which of the following locations? 

Answer Choices:

Correct Answer:

Mucous membranes

Rationale:

🔷 Mucous membranes show true oxygenation changes because they lack melanin; discoloration is more visible than on dark skin.

🔷 Cyanosis appears as a gray, pale, or bluish tinge inside the mouth or conjunctiva, even when the skin tone masks color changes.

🔷 Assessing the oral mucosa gives a reliable indicator for central cyanosis, which reflects low arterial oxygenation.

🔷 Peripheral areas (hands, face) can be misleading, but mucous membranes remain consistent across skin tones.

🔷 Clinical guidelines emphasize oral mucosa for dark-skinned patients for detecting hypoxia earlier and more accurately.

Why the Others Are Incorrect

🔷 Ear lobes: Color change may be subtle or hidden by skin tone; unreliable in dark-skinned clients.

🔷 Nose: Outer skin still contains melanin; cyanosis may not be visible.

🔷 Arms: Too peripheral, affected by cold or circulation, not a reliable sign of hypoxia.
