HESI RN CAT Exam Quizlet
1. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled Amoxicillin (Amoxil) suspension 200 mg/5 ml. How many ml should the nurse administer every 8 hours?
- A. 10 ml
- B. 12.5 ml
- C. 15 ml
- D. 17.5 ml
Correct answer: B
Rationale: To calculate the correct dosage, first, determine the total daily dose: 1.5 grams = 1500 mg. Since the medication is 200 mg/5 ml, for 1500 mg, the nurse needs to administer 1500/200 = 7.5 times the 5 ml dose. Therefore, 7.5 x 5 ml = 37.5 ml total daily dose. To administer this every 8 hours, divide 37.5 ml by 3 (8 hours intervals in a day) to get 12.5 ml to be administered every 8 hours. Choice A, C, and D are incorrect as they do not reflect the correct calculation of the dose based on the prescription and the available concentration.
2. A nurse is preparing to administer an intramuscular injection to a client. Which action should the nurse take to reduce the client's risk of injury?
- A. Use a 1-inch needle
- B. Select a large muscle for the injection
- C. Aspirate for blood return before injecting
- D. Massage the injection site
Correct answer: C
Rationale: The correct answer is to aspirate for blood return before injecting. This action helps ensure that the needle is not in a blood vessel, reducing the risk of injury. Using a 1-inch needle (Choice A) is a standard length for intramuscular injections but does not directly reduce the risk of injury. Selecting a large muscle for the injection (Choice B) is important for proper medication absorption but does not directly reduce the risk of injury. Massaging the injection site (Choice D) can help with medication absorption but does not reduce the risk of injury.
3. The nurse is assessing a client who is 2 days post-op following abdominal surgery. The client reports feeling something 'give way' in the incision site and there is a small amount of bowel protruding from the wound. What action should the nurse take first?
- A. Apply a sterile saline dressing to the wound
- B. Notify the healthcare provider
- C. Administer pain medication
- D. Cover the wound with an abdominal binder
Correct answer: A
Rationale: In this scenario, the nurse should first apply a sterile saline dressing to the wound. This action helps prevent infection and keeps the wound moist, which is crucial in promoting healing. Option B, notifying the healthcare provider, is important but should come after providing immediate wound care. Option C, administering pain medication, is not the priority when there is a small amount of bowel protruding from the wound. Option D, covering the wound with an abdominal binder, is not appropriate for this situation as it does not address the protruding bowel and potential risk for infection.
4. A client with a history of seizures is being discharged with a prescription for phenytoin (Dilantin). Which instruction should the nurse provide this client?
- A. Take the medication with meals
- B. Avoid alcohol while taking this medication
- C. Limit sodium intake
- D. Take the medication at bedtime
Correct answer: B
Rationale: The correct instruction is to advise the client to avoid alcohol while taking phenytoin. Alcohol can interact with phenytoin, making it less effective and leading to increased side effects. Taking the medication with meals (Choice A) may help reduce gastrointestinal upset but is not the most crucial instruction for this medication. Limiting sodium intake (Choice C) is not directly related to phenytoin therapy. Taking the medication at bedtime (Choice D) is not a standard instruction for phenytoin administration.
5. A client with chronic renal failure is being discharged with a prescription for erythropoietin (Epogen). Which statement indicates that the client understands the action of this medication?
- A. It helps my body make red blood cells
- B. It helps prevent infections
- C. It helps my kidneys excrete excess fluid
- D. It helps me breathe easier
Correct answer: A
Rationale: The correct answer is A: 'It helps my body make red blood cells.' Erythropoietin is a medication that stimulates the production of red blood cells in the body. Clients with chronic renal failure often develop anemia due to decreased erythropoietin production by the kidneys. This medication helps address that issue by increasing red blood cell production. Choices B, C, and D are incorrect because erythropoietin does not prevent infections, help kidneys excrete excess fluid, or assist with breathing; its primary action is to boost red blood cell production.
