HESI LPN
Adult Health 2 Exam 1 Questions
Question 1 of 5
Which structures are located in the subcutaneous layer of the skin?
Correct Answer: D
Rationale: The correct answer is D: Adipose cells and blood vessels. The subcutaneous layer, also known as the hypodermis, primarily consists of adipose (fat) tissue and blood vessels. Adipose tissue provides insulation, energy storage, and cushioning, while blood vessels supply nutrients and oxygen. Sebaceous and sweat glands are located in the dermis, which is the layer beneath the epidermis. Melanin and keratin are components of the epidermis, responsible for skin color and waterproofing, respectively. Sensory receptors and hair follicles are found in the dermis and extend into the subcutaneous layer but are not exclusive to it.
Question 2 of 5
A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?
Correct Answer: B
Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.
Question 3 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 4 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 5 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.
