HESI LPN
HESI Practice Test for Fundamentals
1. The healthcare provider is caring for a client who has just been diagnosed with myasthenia gravis. Which symptom should the healthcare provider expect to observe?
- A. Muscle weakness
- B. Joint pain
- C. Vision changes
- D. Skin rash
Correct answer: A
Rationale: Muscle weakness is a hallmark symptom of myasthenia gravis, a neuromuscular disorder characterized by impaired neuromuscular transmission. This results in muscle weakness, particularly in skeletal muscles that control eye movements, facial expressions, chewing, swallowing, and speaking. Joint pain (Choice B) is not a typical symptom of myasthenia gravis and is more commonly associated with conditions like arthritis. Vision changes (Choice C) may occur in conditions affecting the eyes, but they are not specific to myasthenia gravis. Skin rash (Choice D) is also not a typical manifestation of myasthenia gravis. Therefore, the correct answer is muscle weakness (Choice A).
2. The nurse is assessing a client who has just been admitted with a diagnosis of acute pancreatitis. Which finding is most important for the LPN/LVN to report to the healthcare provider immediately?
- A. Elevated serum lipase level
- B. Severe abdominal pain
- C. Nausea and vomiting
- D. Hypotension
Correct answer: D
Rationale: Hypotension is a critical finding that should be reported immediately in a client with acute pancreatitis as it may indicate severe complications such as hemorrhage or shock. While elevated serum lipase level, severe abdominal pain, and nausea/vomiting are common manifestations of acute pancreatitis, hypotension is a more urgent sign requiring immediate attention to prevent further deterioration. Hypotension can be a sign of significant fluid loss, hemorrhage, or sepsis, which are potentially life-threatening conditions that need prompt intervention. Elevated serum lipase levels, severe abdominal pain, and nausea/vomiting are important in the assessment of pancreatitis but do not indicate the same level of immediate danger as hypotension does.
3. A nurse on a medical-surgical unit is caring for a client who has a new prescription for wrist restraints. Which of the following actions should the nurse take?
- A. Pad the client’s wrists before applying the restraints
- B. Tie the restraints to the side rails of the bed
- C. Secure the restraints to the bed frame
- D. Use a quick-release knot to tie the restraints
Correct answer: A
Rationale: The correct action for the nurse to take when a client has a new prescription for wrist restraints is to pad the client’s wrists before applying the restraints. This is important to prevent skin breakdown and injury. Tying the restraints to the side rails of the bed (Choice B) is unsafe and can lead to potential harm for the client. Similarly, securing the restraints to the bed frame (Choice C) is not appropriate as it can restrict the client's movement and cause discomfort. Using a quick-release knot to tie the restraints (Choice D) is also incorrect as it may compromise the effectiveness of the restraints in ensuring client safety.
4. A client is to receive cimetidine (Tagamet) 300 mg q6h IVP. The preparation arrives from the pharmacy diluted in 50 ml of 0.9% NaCl. The LPN plans to administer the IVPB dose over 20 minutes. For how many ml/hr should the infusion pump be set to deliver the secondary infusion?
- A. 150
- B. 50
- C. 100
- D. 75
Correct answer: A
Rationale: Setting the infusion pump to 150 ml/hr ensures the correct administration rate of the IVPB dose over 20 minutes. To calculate the infusion rate, consider that the total volume to be infused is 50 ml over 20 minutes. To convert this to ml/hr, the calculation is (50 ml / 20 minutes) x 60 minutes/hr = 150 ml/hr. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate needed to deliver the secondary infusion over the specified time.
5. Which serum blood finding in diabetic ketoacidosis alerts the nurse that immediate action is required?
- A. pH below 7.3
- B. Potassium of 5.0
- C. HCT of 60
- D. PaO2 of 79%
Correct answer: C
Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.
