HESI CAT Exam 2022 Questions
Question 1 of 5
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?
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.
Question 2 of 5
Which intervention should the nurse include in the plan of care for a patient with tetanus?
Correct Answer: C
Rationale: The correct intervention for a patient with tetanus is to minimize the amount of stimuli in the room. Tetanus can lead to muscle spasms and heightened sensitivity to stimuli, making it essential to reduce environmental triggers for the patient's comfort and safety. Opening window shades for natural light (Choice A) may exacerbate sensitivity to light and worsen symptoms. Encouraging coughing and deep breathing (Choice B) is not directly related to managing tetanus symptoms. While repositioning the patient every hour (Choice D) is important for preventing pressure ulcers, it is not the priority when managing tetanus, which requires a quiet, low-stimulus environment to minimize muscle spasms and discomfort.
Question 3 of 5
Following morning care, a client with C-5 spinal cord injury who is sitting in a wheelchair becomes flushed and complains of a headache. Which intervention should the nurse implement first?
Correct Answer: B
Rationale: In a client with a C-5 spinal cord injury experiencing flushing and a headache, the priority intervention is to assess the client's blood pressure every 15 minutes. These symptoms could indicate autonomic dysreflexia, a potentially life-threatening condition. Assessing the blood pressure is crucial to identify and address this emergency situation promptly. Checking for kinks or obstructions in the Foley tubing (Choice A) is important but not the priority in this scenario. Administering hydralazine (Choice C) without knowing the blood pressure could be harmful as it may lead to a sudden drop in blood pressure. Educating the client on recognizing symptoms of dysreflexia (Choice D) is important for long-term management but is not the immediate action needed in this acute situation.
Question 4 of 5
Before leaving the room of a confused client, the nurse notes that a half bow knot was used to attach the client's wrist restraints to the movable portion of the client's bed frame. What action should the nurse take before leaving the room?
Correct Answer: A
Rationale: The correct action for the nurse to take before leaving the room is to ensure that the knot can be quickly released. Using a half bow knot to attach the client's wrist restraints allows for quick release in case of an emergency. This is crucial for ensuring the safety of the client and complying with restraint policies. Tying the knot with a double turn or square knot (Choice B) would make it difficult to release quickly when needed. Moving the ties so the restraints are secured to the side rails (Choice C) does not address the immediate need for a quick release. Ensuring that the restraints are snug against the client's wrist (Choice D) may not be appropriate if the restraints need to be quickly removed for the client's safety.
Question 5 of 5
An older female client living in a low-income apartment complex tells the home health nurse that she is concerned about her 81-year-old neighbor, a widow whose son recently assumed her financial affairs. Lately, her neighbor has become reclusive but is occasionally seen walking outside wearing only a robe and slippers. What response should the nurse offer?
Correct Answer: C
Rationale: The correct response is to provide the number for Adult Protective Services so the client can report any suspicion of elder abuse. This action allows for an official investigation into possible elder abuse or neglect, ensuring the neighbor's safety and well-being. Choice A is incorrect because assuming dementia without evidence is premature and could lead to overlooking potential abuse. Choice B is incorrect as the situation raises concerns about possible neglect or abuse, which should be reported promptly to the appropriate authorities. Choice D is incorrect as it dismisses the importance of ensuring the safety and well-being of the neighbor in need.
