HESI LPN
Practice HESI Fundamentals Exam
1. While caring for a client who begins to experience a generalized seizure while standing in her room, which of the following actions should the nurse take?
- A. Place a pad under the client’s head
- B. Hold the client’s limbs tightly to prevent injury
- C. Lift the client into bed with the help of other staff members
- D. Insert a bite block into the client’s mouth
Correct answer: A
Rationale: During a seizure, the priority is to protect the client's head and ensure their safety. The nurse should guide the client to the ground if possible and place a soft pad or a folded cloth under the head to prevent injury. Restraining the client's limbs can result in injury and should be avoided. Lifting the client can also lead to injuries during a seizure. Inserting a bite block is contraindicated as it can cause damage to the teeth, oral tissues, and obstruct the airway. Therefore, the correct action is to place a pad under the client's head to protect them during the seizure.
2. A newborn who was born post-term is being assessed by a nurse. Which of the following findings should the nurse expect?
- A. A Rh-negative mother who has an Rh-positive infant
- B. A Rh-positive mother who has an Rh-negative infant
- C. A Rh-positive mother who has an Rh-positive infant
- D. A Rh-negative mother who has an Rh-negative infant
Correct answer: A
Rationale: The correct answer is A: 'A Rh-negative mother who has an Rh-positive infant.' In cases where the newborn is born post-term, the mismatched Rh factor between the mother (Rh-negative) and the infant (Rh-positive) can lead to hemolytic disease of the newborn. This condition occurs when maternal antibodies attack fetal red blood cells, causing hemolysis. This can result in jaundice, anemia, and other serious complications for the infant. Choices B, C, and D are incorrect because they do not reflect the mismatched Rh factor scenario that poses a risk for hemolytic disease of the newborn.
3. A nurse in an outpatient clinic is caring for a client who has a new prescription for an antihypertensive medication. Which of the following instructions should the nurse give the client?
- A. “Get up and change positions slowly.”
- B. “Avoid eating aged cheese and smoked meat.”
- C. “Report any unusual bruising or bleeding to the doctor immediately.”
- D. “Eat the same amount of foods that contain vitamin K every day.”
Correct answer: A
Rationale: The correct instruction for the nurse to give the client who is starting on antihypertensive medication is to 'Get up and change positions slowly.' Antihypertensive medications can cause orthostatic hypotension, a drop in blood pressure when changing positions, so changing positions slowly helps prevent this adverse effect. Choice B about avoiding aged cheese and smoked meat is more relevant for clients taking monoamine oxidase inhibitors (MAOIs) due to potential interactions. Choice C regarding reporting unusual bruising or bleeding is more applicable for clients on anticoagulants. Choice D about consuming consistent amounts of vitamin K-containing foods daily is important for clients taking warfarin, not antihypertensive medications.
4. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?
- A. 18
- B. 27
- C. 36
- D. 45
Correct answer: D
Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.
5. What is the most important aspect of colostomy care to teach the client?
- A. Change the colostomy bag daily
- B. Irrigate the colostomy daily
- C. Avoid high-fiber foods
- D. Assess the stoma for color and swelling
Correct answer: D
Rationale: The most crucial aspect of colostomy care to teach the client is to assess the stoma for color and swelling. This is essential to detect early signs of complications such as ischemia or infection. Changing the colostomy bag daily is important but not as critical as assessing the stoma for complications. Irrigating the colostomy daily is not a standard recommendation and should be performed based on healthcare provider's instructions. While avoiding high-fiber foods may be beneficial for some individuals with a colostomy, it is not the most important aspect of care compared to monitoring the stoma for complications.
