HESI LPN
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. The healthcare provider is preparing to administer an IM injection to an adult client. Which site is the preferred location for this injection?
- A. Deltoid muscle
- B. Vastus lateralis muscle
- C. Ventrogluteal muscle
- D. Dorsogluteal muscle
Correct answer: C
Rationale: The ventrogluteal site is the preferred site for IM injections in adults due to its muscle mass and low risk of nerve injury. The deltoid muscle, although commonly used for vaccines in adults due to easy accessibility, has a smaller muscle mass making it less ideal for IM injections. The vastus lateralis muscle is typically used in infants and young children, not in adults. The dorsogluteal site has a higher risk of injury to the sciatic nerve and is no longer recommended for IM injections in any age group.
3. A client's medication sheet contains a prescription for sertraline (Zoloft). To ensure safe administration of the medication, a nurse would administer the dose:
- A. On an empty stomach
- B. At the same time each evening
- C. Evenly spaced around the clock
- D. As needed when the client complains of depression
Correct answer: B
Rationale: The correct answer is B: 'At the same time each evening.' Sertraline should be administered at the same time each evening to maintain steady drug levels and effectiveness. Choice A is incorrect because sertraline can be taken with or without food. Choice C is incorrect as sertraline does not need to be spaced around the clock. Choice D is incorrect as sertraline is a scheduled medication and should not be taken on an as-needed basis for complaints of depression.
4. Which nursing intervention provides the most support to the parents of an infant with an obvious physical anomaly?
- A. Encourage them to express their concerns.
- B. Discourage them from talking about their baby.
- C. Assure them not to worry because the anomaly can be repaired.
- D. Show them postoperative photographs of infants who had a similar anomaly.
Correct answer: A
Rationale: Encouraging parents to express their concerns is the most supportive intervention as it allows them to process their emotions and provides an opportunity for the nurse to offer appropriate support and information. This choice focuses on validating the parents' feelings and creating an open communication channel. Choices B and C are incorrect as they can hinder the parents' emotional processing and may provide false reassurance. Choice D, showing postoperative photographs, may not be appropriate at this stage as it might not address the parents' current emotional needs and could induce anxiety or unrealistic expectations.
5. When a healthcare professional makes an initial assessment of a client who is post-op following gastric resection, the client's NG tube is not draining. The healthcare professional's attempt to irrigate the tube with 10ml of 0.9% NaCl was unsuccessful, so they determine that the tube was obstructed. Which of the following actions should the healthcare professional take?
- A. Notify the healthcare provider.
- B. Attempt to irrigate the tube with a larger volume of saline.
- C. Replace the NG tube with a new one.
- D. Reposition the client to see if that helps the tube drain.
Correct answer: A
Rationale: If an NG tube is obstructed and cannot be irrigated successfully, notifying the healthcare provider is the appropriate action to take for further management. This is crucial as the healthcare provider may need to assess the situation, provide guidance, or intervene with specific interventions. Attempting to irrigate the tube with a larger volume of saline (Choice B) may exacerbate the situation if the tube is truly obstructed. Replacing the NG tube with a new one (Choice C) should not be the initial action unless advised by the healthcare provider. Repositioning the client (Choice D) may not necessarily resolve the tube obstruction and should not be the primary intervention in this scenario.
