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 A

Explanation

A. Asking about regular painkiller (NSAID) use is correct because nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin and ibuprofen are a major risk factor for peptic ulcer disease. They can damage the gastric mucosa and increase acid production, leading to ulcer formation.
B. Vitamin supplements are not a common cause of peptic ulcer disease. While some supplements can cause gastrointestinal discomfort, they are not a primary risk factor.
C. High-fat foods can contribute to acid reflux or indigestion but are not a direct cause of peptic ulcers. Peptic ulcer disease is primarily linked to Helicobacter pylori infection and NSAID use.
D. Stress was once thought to be a major cause of ulcers, but current research indicates that it plays a minor role compared to factors like H. pylori infection and NSAID use.

A. Increased urinary output. B. Increased heart rate. C. Decreased heart rate. D. Hypoglycemia.

Correct Answer is B

Explanation

A. Increased urinary output is incorrect because NSAIDs like ibuprofen can cause kidney damage, leading to fluid retention and decreased urine output, not increased output.
B. Increased heart rate is correct. Long-term NSAID use can cause gastrointestinal (GI) irritation and ulcers, which may lead to occult blood loss and anemia. Anemia can result in tachycardia (increased heart rate) as the body compensates for decreased oxygen delivery. C. Decreased heart rate is incorrect because anemia and pain typically cause tachycardia, not bradycardia.
D. Hypoglycemia is incorrect because NSAIDs do not significantly impact blood glucose levels.
