HESI Fundamentals Exam
1. The healthcare professional prepares a 1,000 ml IV of 5% dextrose and water to be infused over 8 hours. The infusion set delivers 10 drops per milliliter. The healthcare professional should regulate the IV to administer approximately how many drops per minute?
- A. 80
- B. 8
- C. 21
- D. 25
Correct answer: C
Rationale: To calculate the drops per minute for the IV infusion, first determine the total drops to be infused over 8 hours. 1,000 ml to be infused over 8 hours means 125 ml per hour (1000 ml / 8 hours = 125 ml/hr). Since the infusion set delivers 10 drops per ml, 125 ml/hr x 10 drops/ml = 1250 drops/hr. To find drops per minute, divide the drops per hour by 60 (minutes in an hour): 1250 drops/hr / 60 minutes = 20.83 drops/minute, which rounds up to 21 drops per minute (Option C). This rate ensures the correct infusion rate over 8 hours. Choices A, B, and D are incorrect calculations and do not provide the appropriate infusion rate needed to administer the IV over the specified time period.
2. While caring for a client who is postoperative and has refused to use an incentive spirometer following major abdominal surgery, what is the nurse's priority action?
- A. Request that a respiratory therapist discuss the technique for using the incentive spirometer
- B. Determine the reasons why the client is refusing to use the incentive spirometer
- C. Document the client's refusal to participate in health restorative activities
- D. Administer a pain medication to the client
Correct answer: B
Rationale: The nurse's priority is to determine the reasons why the client is refusing to use the incentive spirometer. By understanding the client's concerns or barriers, the nurse can address them appropriately. Requesting a respiratory therapist (Choice A) may be necessary later but is not the priority. Documenting the refusal (Choice C) is important but does not address the immediate need to assess and intervene. Administering pain medication (Choice D) without addressing the root cause of refusal is not appropriate and may mask the issue rather than resolve it.
3. An 80-year-old client admitted with a diagnosis of a possible cerebral vascular accident has had a blood pressure ranging from 180/110 to 160/100 over the past 2 hours. The nurse has also noted increased lethargy. Which assessment finding should the nurse report immediately to the healthcare provider?
- A. Slurred speech
- B. Incontinence
- C. Muscle weakness
- D. Rapid pulse
Correct answer: A
Rationale: Slurred speech is a classic sign of a worsening stroke, suggesting a potential blockage or hemorrhage affecting speech centers in the brain. Prompt reporting of this symptom to the healthcare provider is crucial for immediate evaluation and intervention. While incontinence (Choice B) is important to monitor, it is not considered an immediate priority over slurred speech in this context. Muscle weakness (Choice C) and rapid pulse (Choice D) are also relevant in stroke assessment, but slurred speech takes precedence due to its strong association with neurological deficits in the setting of a possible cerebral vascular accident.
4. A nurse is teaching an older adult client who has type 2 diabetes mellitus about how to care for corns and calluses on her toes. Which of the following statements by the client indicates an understanding of the teaching?
- A. I can place an oval corn pad over toes that have corns as long as I remove the pad weekly
- B. I should soak my feet in warm water daily to soften corns and calluses
- C. I can apply lotion to soften calluses as long as I don’t put lotion between my toes
- D. I should use an over the counter liquid medication to remove corns
Correct answer: C
Rationale: Applying lotion to the feet, avoiding between toes, is correct; over-the-counter treatments and soaking are not recommended.
5. While suctioning a client's nasopharynx, the nurse observes that the client's oxygen saturation remains at 94%, which is the same reading obtained prior to starting the procedure. What action should the nurse take in response to this finding?
- A. Complete the intermittent suction of the nasopharynx.
- B. Reposition the pulse oximeter clip to obtain a new reading.
- C. Stop suctioning until the pulse oximeter reading is above 95%.
- D. Apply an oxygen mask over the client's nose and mouth.
Correct answer: A
Rationale: The correct action for the nurse to take in this situation is to complete the intermittent suction of the nasopharynx. Since the oxygen saturation remains stable at 94%, which was the initial reading, it indicates that the procedure is not causing a significant drop in oxygen levels. Stopping the suctioning or applying oxygen may not be necessary as the saturation level is within an acceptable range. Repositioning the pulse oximeter clip is unlikely to change the reading significantly. Therefore, completing the procedure maintains care consistency and effectiveness, ensuring proper airway management without unnecessary interventions. Choices B, C, and D are incorrect because repositioning the pulse oximeter clip, stopping suctioning until a higher reading is achieved, and applying oxygen are not warranted based on the stable oxygen saturation level of 94% throughout the procedure.
