HESI Fundamentals Practice Questions
1. The client is receiving total parenteral nutrition (TPN). Which laboratory value should the LPN/LVN monitor closely to assess for complications?
- A. Serum potassium
- B. Blood glucose
- C. Serum sodium
- D. Serum calcium
Correct answer: B
Rationale: The correct answer is B: Blood glucose. When caring for a client receiving total parenteral nutrition (TPN), monitoring blood glucose levels is essential due to the risk of hyperglycemia. TPN solutions are high in glucose, and clients may be at risk of developing hyperglycemia if the infusion rate is too high or if there are underlying issues such as insulin resistance. Monitoring serum potassium (choice A) is important but not the most crucial value to monitor in clients receiving TPN. Serum sodium (choice C) and serum calcium (choice D) are not directly impacted by TPN administration and are less likely to be affected compared to blood glucose levels.
2. A client with chronic kidney disease is being assessed. Which laboratory value would be most concerning?
- A. Serum creatinine of 3.0 mg/dL
- B. Blood urea nitrogen (BUN) of 45 mg/dL
- C. Serum potassium of 6.5 mEq/L
- D. Hemoglobin of 10 g/dL
Correct answer: C
Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.
3. A client who is nonambulatory notifies the nurse that his trash can is on fire. After the nurse confirms the fire, which of the following actions should the nurse take next?
- A. Activate the emergency fire alarm
- B. Extinguish the fire
- C. Evacuate the client
- D. Confine the fire
Correct answer: C
Rationale: The correct action for the nurse to take next, after confirming the fire, is to evacuate the client. In a fire situation, following the RACE mnemonic, the priority is to rescue or evacuate clients to ensure their safety. Activating the emergency fire alarm (Choice A) is important to alert others and the fire department, but evacuating the client takes precedence. Extinguishing the fire (Choice B) may put the nurse and client at risk and is best left to trained personnel. Confining the fire (Choice D) is not the nurse's responsibility; the focus should be on ensuring the client's safety by evacuating them.
4. A client who has a new prescription for warfarin (Coumadin) is receiving discharge teaching from a nurse. Which of the following statements indicates that the client understands the teaching?
- A. I will take my warfarin at the same time every day.
- B. I should use a soft-bristled toothbrush while taking this medication.
- C. I should take my warfarin at bedtime.
- D. I should avoid eating foods high in vitamin K while taking this medication.
Correct answer: A
Rationale: The correct answer is A. Taking warfarin at the same time every day is essential to maintain a consistent blood level of the medication. This statement indicates that the client understands the teaching about the importance of consistency in medication timing. Choice B, regarding using a soft-bristled toothbrush, is not directly related to warfarin therapy and does not assess the client's understanding of warfarin administration. Choice C suggesting taking warfarin at bedtime is incorrect; it is generally recommended to take warfarin at the same time each day to avoid variations in drug levels. Choice D about avoiding foods high in vitamin K is relevant as vitamin K can interfere with warfarin's anticoagulant effects. However, it is not the best indicator of understanding the teaching on medication timing, which is crucial for warfarin efficacy.
5. A young mother of three children complains of increased anxiety during her annual physical exam. What information should the LPN/LVN obtain first?
- A. Sexual activity patterns.
- B. Nutritional history.
- C. Leisure activities.
- D. Financial stressors.
Correct answer: B
Rationale: The LPN/LVN should first obtain the nutritional history in this scenario. Nutrition plays a crucial role in mental health, and deficiencies or imbalances in diet can contribute to anxiety symptoms. Understanding the mother's nutritional intake can help identify any factors exacerbating her anxiety. Sexual activity patterns are not directly relevant to her anxiety symptoms unless specifically indicated. Leisure activities and financial stressors may be important but are secondary to addressing the potential impact of nutrition on anxiety.
