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: C

Rationale: Infiltration occurs when the IV fluid leaks into the surrounding tissue instead of entering the bloodstream properly. Skin blanching, swelling, and coolness at the IV site are typical signs of infiltration. Purulent exudate (choice A) is associated with infection, warmth (choice B) can indicate phlebitis, and bleeding (choice D) may occur if the IV catheter punctures a blood vessel.

Correct Answer: C

Rationale: In the scenario described, when a client arrives unconscious, priority should be given to a notarized original copy of advance directives brought in by the partner. Advance directives are legal documents that specify a person's healthcare wishes and decision-making preferences in advance. These directives guide healthcare providers in delivering care according to the client's preferences when the client is unable to communicate. The statement of client rights and the client self-determination act (Choice A) are important but do not provide specific care instructions. Orders written by the healthcare provider (Choice B) may not reflect the client's wishes. Clinical pathway protocols (Choice D) are valuable but do not address the individualized care preferences of the client.

Correct Answer: C

Rationale: The nurse should notify the admissions office and wait to apply the bracelet. By doing so, the nurse ensures patient safety and accuracy in identification. Changing the incorrect item (Choice A) could lead to errors and confusion in the patient's identification. Using the mismatched items until a replacement is supplied (Choice B) compromises patient safety and could result in errors during care delivery. Making a corrected identification bracelet without verifying the correct information (Choice D) could introduce further inaccuracies and risks in patient identification.

Correct Answer: D

Rationale: The correct answer is D because there is no need to wait 72 hours before allowing the child to stand. The synthetic cast does not affect weight-bearing capacity, and standing can be done as tolerated. Choice A is incorrect because keeping the cast covered can lead to damage or accidents. Choice B is acceptable as applying an ice pack can help relieve itching. Choice C is also correct as elevating the cast on pillows can help reduce swelling and promote comfort during rest.
