HESI Fundamentals Practice Questions Questions
Question 1 of 5
A healthcare professional is preparing to administer lactated Ringer's (LR) IV 100 mL over 15 min. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)
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.
Question 2 of 5
When teaching a client how to administer medication through a jejunostomy tube, which of the following instructions should the nurse include?
Correct Answer: A
Rationale: The correct answer is to flush the tube before and after each medication administration. This helps prevent clogging and ensures the medication is delivered properly. Mixing medications with enteral feeding (choice B) is incorrect as medications should be administered separately. Pushing tablets through the tube (choice C) is not recommended as they should be properly dissolved before administration. Mixing all crushed medications before dissolving them in water (choice D) is incorrect; medications should be dissolved individually to avoid interactions or inconsistencies in dosages.
Question 3 of 5
When a nurse instructs a client with hearing loss about cleaning their new hearing aids, which statement indicates that the client understands the instructions?
Correct Answer: A
Rationale: The correct answer is A because cleaning the outside part of hearing aids with a damp cloth is an appropriate method. Rubbing alcohol can damage ear molds, so choice B is incorrect. Keeping the volume of hearing aids turned up high may lead to discomfort, making choice C incorrect. Removing batteries when not in use at night is good practice for battery life, but it does not directly relate to understanding cleaning instructions, so choice D is less relevant in this context.
Question 4 of 5
A client expresses that, based on religious values and mandates, a blood transfusion is not an acceptable treatment option. Which of the following responses should the nurse make?
Correct Answer: D
Rationale: The correct response is to involve the client's religious and spiritual leaders in the discussion to find a solution that respects both the client's values and medical needs. Option A is incorrect as it dismisses the client's beliefs. Option B assumes the family's opinion over the client's. Option C is inappropriate as it questions the client's religious beliefs rather than addressing the concern respectfully.
Question 5 of 5
During an integumentary assessment for a group of clients, a healthcare professional notes various skin findings. Which of the following findings should the professional recognize as requiring immediate intervention?
Correct Answer: B
Rationale: Cyanosis, a bluish discoloration of the skin, indicates inadequate oxygenation and requires immediate intervention. It suggests a severe lack of oxygen in the blood, which can be life-threatening. Pallor and jaundice are concerning findings but may not indicate an immediate life-threatening situation. Pallor can be a sign of anemia or low blood pressure, while jaundice may indicate liver dysfunction. Erythema, which is redness of the skin, is typically not an emergency and can be caused by various factors such as inflammation or increased blood flow to the area.
