HESI LPN
Adult Health 2 Exam 1 Questions
Question 1 of 5
What is the primary function of neutrophils?
Correct Answer: C
Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.
Question 2 of 5
A client with chronic kidney disease is being evaluated for dialysis. Which laboratory value would be most concerning to the nurse?
Correct Answer: B
Rationale: The correct answer is B: Potassium 6.2 mEq/L. In chronic kidney disease, the kidneys struggle to regulate potassium levels, leading to hyperkalemia. A potassium level of 6.2 mEq/L is dangerously high and can cause life-threatening cardiac arrhythmias. Hemoglobin of 9.5 g/dL may indicate anemia, which is common in chronic kidney disease but is not immediately life-threatening. Creatinine and BUN levels are markers of kidney function; although elevated levels indicate kidney impairment, they are not acutely life-threatening like severe hyperkalemia.
Question 3 of 5
The nurse is caring for a client with acute pancreatitis. Which intervention should be included in the plan of care?
Correct Answer: C
Rationale: The correct intervention to include in the plan of care for a client with acute pancreatitis is to administer intravenous fluids as prescribed. Intravenous fluids are crucial to maintain hydration and electrolyte balance in clients with acute pancreatitis. Providing a high-protein diet (Choice A) is not recommended initially for clients with acute pancreatitis, as they may need to be kept NPO (nothing by mouth) to rest the pancreas. Encouraging oral fluids (Choice B) may not be appropriate if the client is experiencing severe symptoms and requires intravenous fluids. Monitoring for signs of hyperglycemia (Choice D) is important but not the immediate intervention needed to address the fluid and electrolyte imbalances associated with acute pancreatitis.
Question 4 of 5
The nurse is caring for a client with a history of seizure disorder who is receiving phenytoin (Dilantin). Which laboratory value is most important to monitor?
Correct Answer: A
Rationale: Corrected Rationale: Monitoring the phenytoin level is crucial to ensure it is within the therapeutic range and to prevent toxicity. Monitoring sodium level is important in clients receiving lithium, not phenytoin. Hemoglobin level and white blood cell count are not directly related to phenytoin therapy monitoring.
Question 5 of 5
The nurse is assessing a client with cirrhosis who has developed ascites. What is the most important intervention to include in the care plan?
Correct Answer: D
Rationale: The correct answer is to administer diuretics as prescribed. Diuretics are often prescribed to help manage fluid accumulation in ascites, which is a common complication of cirrhosis. Restricting sodium intake (Choice A) is essential in managing ascites, but administering diuretics takes precedence in the care plan. Encouraging high-protein meals (Choice B) and increasing fluid intake (Choice C) are not the primary interventions for managing ascites in cirrhosis.
