HESI CAT Exam 2022
1. 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.
2. The nurse provides discharge teaching to a client who was recently diagnosed with diabetes mellitus (DM). After receiving the instructions, the client expresses understanding about when, how, and why to take his prescribed medications at home. Which intervention is most important for the nurse to implement?
- A. Review the purpose of medications prescribed for the client to take home with him
- B. Provide the client with a printed list of medications and a schedule for administration
- C. Send a list of medications taken while hospitalized to the client’s healthcare provider
- D. Offer to consult with the pharmacist about resources for reduced-price medications
Correct answer: B
Rationale: Providing the client with a printed list of medications and a schedule for administration is crucial to ensure adherence and understanding of the medication regimen at home. This intervention helps the client follow the prescribed treatment plan accurately. Choice A is not as essential since the client already understands when, how, and why to take the medications. Choice C is not a priority at this point as the client needs information for home medication management. Choice D, while helpful, is not the most important intervention compared to providing a clear list and schedule for medication administration.
3. The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to contracting lead poisoning?
- A. An adolescent who works part-time in a paint factory
- B. A 2-year-old who plays on aging outdoor playground equipment
- C. A 10-year-old who has Type 1 diabetes mellitus
- D. An 8-year-old who lives in a housing project
Correct answer: B
Rationale: Children playing on aging playground equipment are at higher risk of lead poisoning due to potential exposure from old paint. This is because deteriorating paint on older playground equipment may contain lead, which can be ingested by young children. Choices A, C, and D do not directly involve potential exposure to lead paint, making them less susceptible to lead poisoning compared to a child playing on aging playground equipment.
4. What should be the school nurse's first action after being notified that Child A has bitten Child B on the arm, resulting in broken skin but no bleeding?
- A. Apply antibiotic cream to Child B’s arm immediately
- B. Determine if Child A has a history of Hepatitis C or HIV
- C. Determine the date of Child B’s latest tetanus booster
- D. Wash Child B’s arm thoroughly with soap and water
Correct answer: D
Rationale: The correct first action for the school nurse to take in this situation is to wash Child B’s arm thoroughly with soap and water. Washing the wound immediately is crucial to reduce the risk of infection from the bite. Applying antibiotic cream may come after cleaning the wound. Determining Child A's medical history or checking Child B's tetanus status is important but not the immediate priority when dealing with a bite wound.
5. A client with chronic alcoholism is admitted with a decreased serum magnesium level. Which snack option should the nurse recommend to this client?
- A. Cheddar cheese and crackers
- B. Carrot and celery sticks
- C. Beef bologna sausage slices
- D. Dry roasted almonds
Correct answer: D
Rationale: Dry roasted almonds are the most suitable snack option for a client with chronic alcoholism and a decreased serum magnesium level because they are high in magnesium. Magnesium is essential in addressing the deficiency. Cheddar cheese and crackers (Choice A) do not contain as much magnesium as almonds. Carrot and celery sticks (Choice B) are healthy choices but do not provide a significant amount of magnesium. Beef bologna sausage slices (Choice C) are not a good choice as processed meats are not rich in magnesium.
