Correct Answer: C

Rationale: All of the above findings should be reported to the healthcare provider for prompt evaluation and treatment. Swollen lymph nodes in the groin indicate regional lymphatic involvement, a core body temperature of 100.5°F suggests a mild fever response, and an elevated white blood cell count indicates an ongoing infection process. These findings collectively point towards the spread of infection and require immediate attention to prevent further complications.

Correct Answer: B

Rationale: The correct answer is to check the client's blood glucose level. This is the priority action when dealing with a client admitted with hyperglycemia. Checking the blood glucose level helps determine the severity of hyperglycemia and guides further treatment. Administering insulin or fluids or monitoring intake and output are important interventions but should come after assessing the blood glucose level to inform the most appropriate course of action.

Correct Answer: B

Rationale: Engaging in regular physical activity is a crucial lifestyle modification for managing hypertension. Regular exercise helps improve cardiovascular health, lower blood pressure, and contribute to overall well-being. Choices A, C, and D are incorrect. Increasing sodium intake is not recommended for hypertension as it can worsen fluid retention and elevate blood pressure. Increasing caffeine intake is also not advised as it may lead to increased heart rate and blood pressure. Reducing potassium intake is not beneficial as potassium is essential for maintaining healthy blood pressure levels.

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin. Erythropoietin stimulates the production of red blood cells, leading to an increase in hemoglobin levels. Monitoring hemoglobin is crucial to assess the effectiveness of the treatment. Choices A, C, and D are incorrect. Serum potassium levels are often monitored in chronic kidney disease, but it is not the primary parameter to evaluate the effectiveness of erythropoietin therapy. White blood cell count and platelet count are not directly influenced by erythropoietin injections for chronic kidney disease.

Correct Answer: C

Rationale: In SIADH, there is excessive ADH secretion leading to water retention and dilutional hyponatremia. The most crucial intervention is to restrict fluid intake to prevent further fluid overload and worsening of hyponatremia. Encouraging oral hydration (choice A) would exacerbate the condition by adding more fluids. Monitoring for signs of dehydration (choice B) is not appropriate as the client is at risk of fluid overload. Administering IV fluids (choice D) would worsen the hyponatremia and should be avoided.
