The nurse is caring for a client with a nasogastric tube to continuous suction. Which electrolyte imbalance should the nurse monitor for?

• A. Hypercalcemia.
• B. Hypokalemia.
• C. Hyponatremia.
• D. Hypomagnesemia.

Correct Answer: B
Rationale: Hypokalemia is a common electrolyte imbalance in clients with a nasogastric tube to continuous suction because potassium is lost through gastric fluids.

The nurse is caring for a client with liver cirrhosis. Which assessment finding requires immediate intervention?

• A. Jaundice.
• B. Ascites.
• C. Peripheral edema.
• D. Spider angiomas.

Correct Answer: D
Rationale: Spider angiomas are abnormal clusters of blood vessels near the skin surface and can be indicative of an underlying liver condition. In the context of liver cirrhosis, spider angiomas can suggest portal hypertension and liver dysfunction, which requires immediate intervention. Jaundice (choice A) is a common manifestation of liver cirrhosis but not typically an immediate intervention priority unless severe. Ascites (choice B) and peripheral edema (choice C) are also common in liver cirrhosis but do not require immediate intervention unless they are causing respiratory compromise or other urgent issues.

The healthcare provider is inspecting the external eye structures of a client. Which finding is a normal racial variation?

• A. Blue sclerae.
• B. Brown macules on the sclerae.
• C. Slightly yellow sclerae in an African-American client.
• D. Conjunctival pallor.

Correct Answer: C
Rationale: The slightly yellow color of the sclera is a normal racial variation found in the African-American population. Blue sclerae (Choice A) are associated with osteogenesis imperfecta, not a normal racial variation. Brown macules on the sclerae (Choice B) may indicate issues like melanoma or melanosis but are not a normal racial variation. Conjunctival pallor (Choice D) suggests anemia or decreased blood flow but is not a normal racial variation.

A community health nurse is planning a program to reduce the incidence of heart disease in the community. Which intervention should the nurse prioritize?

• A. Distributing educational materials on heart-healthy diets
• B. Organizing free cholesterol screenings
• C. Holding workshops on stress management
• D. Partnering with local gyms to offer fitness classes

Correct Answer: B
Rationale: The correct answer is B: Organizing free cholesterol screenings. This intervention is crucial because it helps identify individuals at risk for heart disease by assessing their cholesterol levels. High cholesterol is a significant risk factor for heart disease, and identifying it early can lead to timely interventions and medical care. Choices A, C, and D, while beneficial for overall health, may not directly address the specific risk factor of high cholesterol associated with heart disease. Distributing educational materials on heart-healthy diets (A) could be helpful in preventing heart disease, but identifying individuals already at risk is a more urgent need. Holding workshops on stress management (C) and partnering with local gyms for fitness classes (D) are important for overall health promotion but may not target the specific risk factor of high cholesterol as directly as organizing cholesterol screenings.
