HESI Fundamentals Practice Questions

Correct Answer: A

Rationale: To administer 100 mL over 15 min, the IV pump should be set to deliver 400 mL/hr. This calculation is based on the concept that if 100 mL is given in 15 minutes, to find out how many milliliters are given in an hour, you would multiply by 4 (since 15 minutes is a quarter of an hour). Therefore, 100 mL x 4 = 400 mL per hour. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate required to administer 100 mL over 15 minutes.

Correct Answer: A

Rationale: Montgomery straps are the correct choice in this scenario. They are specifically designed to secure dressings around drain sites, like Penrose drains, and are ideal for frequent dressing changes. Sterile gauze (Choice B) is commonly used for wound dressings but may not provide the best securement for drains. Adhesive tape (Choice C) can cause skin irritation and may not be suitable for securing drains. Elastic bandages (Choice D) are typically used for compression or support but are not appropriate for securing dressings around drain sites.

Correct Answer: A

Rationale: When caring for a client who speaks a different language, it is essential to communicate through an interpreter. Talking directly to the client, rather than the interpreter, ensures clear and respectful interaction. Speaking loudly to the interpreter (choice B) is not necessary and may be perceived as disrespectful. Using gestures (choice C) alone may lead to misunderstandings or misinterpretations. Avoiding the use of an interpreter and relying solely on family members (choice D) can compromise the accuracy and confidentiality of the communication.

Correct Answer: D

Rationale: Information about transmission-based precautions is essential for infection control and continuity of care.

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.
