The nurse is performing an assessment of a client admitted to the emergency department with respiratory distress. The nurse should carefully inspect which part of the body to identify central cyanosis?

Oral mucosa

Palms

Sclera

Nail beds

Answer and Explanation

The Correct Answer is A

A. Oral mucosa is correct. Central cyanosis occurs when oxygen saturation is significantly reduced and is best assessed in areas with rich vascular supply, such as the oral mucosa, lips, and tongue.
B. Palms are incorrect because peripheral cyanosis (often due to cold exposure or poor circulation) can cause blue-tinged extremities, but this does not indicate central cyanosis.
C. Sclera is incorrect because cyanosis does not affect the sclera; however, jaundice does.
D. Nail beds are incorrect because, like the palms, they are more indicative of peripheral cyanosis, which can result from localized poor perfusion rather than central oxygenation problems.

Correct Answer is C

Explanation

A. Delaying follow-up for two weeks is inappropriate when symptoms suggest a possible serious metabolic disorder, such as diabetes. Immediate testing is needed.
B. Simply documenting the findings as benign is incorrect because hyperpigmentation in these areas (acanthosis nigricans) can be a sign of insulin resistance, which requires further evaluation.
C. Performing a random blood sugar test per order is correct. The symptoms of fatigue, thirst, and frequent urination, along with acanthosis nigricans, strongly suggest diabetes mellitus or insulin resistance. A random blood glucose test can help determine if the client has hyperglycemia.
D. While certain malignancies can be associated with acanthosis nigricans, diabetes is a more common cause. Asking about cancer history is not the priority intervention.

A. Drink fluids before and after, but not during, meals B. Sit with the head of the bed at a 45-degree angle during meals C. Thoroughly chew small amounts of food with each mouthful D. Be aware of the possibility of temporomandibular joint pain

Correct Answer is C

Explanation

A. Drinking fluids before and after meals but not during meals is incorrect. Clients with dysphagia may require thickened liquids and should sip fluids as needed to facilitate swallowing.
B. Sitting with the head of the bed at a 45-degree angle is incorrect. Clients with dysphagia should be positioned at a 90-degree angle (fully upright) during meals to reduce the risk of aspiration.
C. Thoroughly chewing small amounts of food with each mouthful is correct. Clients with dysphagia should eat slowly, take small bites, and chew food thoroughly to prevent choking and aspiration.
D. Temporomandibular joint pain is not a common issue associated with dysphagia following a stroke. The primary concern is the risk of aspiration.
