HESI LPN
HESI Fundamentals Exam
1. A healthcare professional is preparing to administer 750 mL of 0.9% sodium chloride IV to infuse over 7 hours. The healthcare professional should set the pump to deliver how many mL/hr?
- A. 107 mL/hr
- B. 75 mL/hr
- C. 90 mL/hr
- D. 60 mL/hr
Correct answer: A
Rationale: To calculate the mL/hr rate for the infusion, divide the total volume (750 mL) by the total time (7 hours). 750 mL รท 7 hours = 107 mL/hr. This means that the pump should be set to deliver approximately 107 mL/hr. Choice B (75 mL/hr) is incorrect because it does not reflect the correct calculation. Choice C (90 mL/hr) is incorrect as it does not align with the accurate calculation. Choice D (60 mL/hr) is incorrect as it does not match the correct mL/hr rate obtained through the calculation.
2. Which action is most important for maintaining sterility when donning sterile gloves?
- A. Maintain thumbs at a ninety-degree angle.
- B. Hold hands with fingers pointing downward while gloving.
- C. Keep gloved hands above the elbows.
- D. Put the glove on the dominant hand first.
Correct answer: C
Rationale: The most crucial action for maintaining sterility when donning sterile gloves is to keep gloved hands above the elbows. This practice is essential to prevent potential contamination and maintain a sterile field. Choices A, maintaining thumbs at a ninety-degree angle, and B, holding hands with fingers pointing downward while gloving, are not as critical as keeping hands above the elbows for maintaining sterility. Choice D, putting the glove on the dominant hand first, is not as important as ensuring that gloved hands are kept above the elbows to maintain sterility.
3. A client who has an indwelling catheter reports a need to urinate. Which of the following actions should the nurse take?
- A. Check the catheter to see whether it is patent.
- B. Reassure the client that it is not possible for them to urinate.
- C. Re-catheterize the bladder with a larger-gauge catheter.
- D. Collect a urine specimen for analysis.
Correct answer: A
Rationale: When a client with an indwelling catheter reports a need to urinate, the nurse's initial action should be to check the catheter for patency. This is crucial to ensure that the catheter is not blocked, twisted, or kinked, which could lead to urinary retention. Reassuring the client without assessing the catheter could delay necessary interventions. Re-catheterizing the bladder with a larger-gauge catheter should not be the first step unless catheter patency is confirmed as an issue. Collecting a urine specimen for analysis is important but not the immediate priority when the client reports a need to urinate.
4. A healthcare professional is preparing to assess a patient for orthostatic hypotension. Which piece of equipment will the professional obtain to assess for this condition?
- A. Thermometer
- B. Elastic stockings
- C. Blood pressure cuff
- D. Sequential compression devices
Correct answer: C
Rationale: To assess for orthostatic hypotension, a healthcare professional needs to obtain a blood pressure cuff. Orthostatic hypotension is defined as a drop in blood pressure greater than 20 mm Hg in systolic pressure or 10 mm Hg in diastolic pressure when moving from lying down to a standing position. A thermometer (Choice A) is used to measure body temperature and is not directly related to assessing orthostatic hypotension. Elastic stockings (Choice B) are used for preventing deep vein thrombosis and improving circulation in the lower extremities, not for assessing orthostatic hypotension. Sequential compression devices (Choice D) are mechanical pumps that are used to prevent deep vein thrombosis and are not specifically used for assessing orthostatic hypotension.
5. A client who has had an allogeneic stem cell transplant needs protective measures. What precaution should the nurse plan for this client?
- A. Ensure the client wears a mask when outside the room if there is construction nearby.
- B. Place the client in a private room with positive pressure airflow.
- C. Restrict all visitors from seeing the client.
- D. Provide a HEPA filter in the client's room.
Correct answer: A
Rationale: For a client who has undergone an allogeneic stem cell transplant, it is crucial to minimize exposure to potential sources of infection. Wearing a mask when outside the room, especially in areas with construction or other potential risks, helps protect the client's compromised immune system. Positive pressure airflow rooms are typically used for clients with airborne infections, not for those post-stem cell transplant. Restricting all visitors may contribute to the client's well-being, but it is not a direct protective measure against infection. While HEPA filters can be beneficial in maintaining air quality, wearing a mask when exposed to external risks is a more targeted and immediate protective measure in this scenario.
