HESI Fundamentals Study Guide Questions
Question 1 of 4
A nurse is preparing to administer multiple medications to a client who has an enteral feeding tube. Which of the following actions should the nurse plan to take?
Correct Answer: D
Rationale: The correct action the nurse should take when administering multiple medications to a client with an enteral feeding tube is to flush the tube with 15-30 mL of sterile water before and between medications, and 30-60 mL after the last medication. This helps prevent clogging and ensures each medication is delivered effectively. Choice A is incorrect as medications should not be dissolved in water for administration through an enteral feeding tube. Choice B is incorrect because each medication should be drawn up and administered separately to prevent any potential interactions. Choice C is incorrect as resistance while pushing the plunger may indicate a problem that needs to be addressed before continuing with the administration.
Question 2 of 4
A healthcare professional is reviewing a client's fluid and electrolyte status. Which of the following findings should the healthcare professional report to the provider?
Correct Answer: D
Rationale: The correct answer is D. A potassium level of 5.4 mEq/L is above the expected reference range, indicating hyperkalemia. Hyperkalemia can lead to serious complications such as dysrhythmias, making it important for the healthcare professional to report this finding to the provider for further evaluation and intervention. Choices A, B, and C fall within normal ranges and do not pose an immediate risk to the client's health, so they would not warrant immediate reporting to the provider. Elevated BUN or creatinine levels may indicate kidney dysfunction, while a sodium level of 143 mEq/L falls within the normal range for adults and does not typically require urgent intervention.
Question 3 of 4
A client who is nonambulatory notifies the nurse that his trash can is on fire. After the nurse confirms the fire, which of the following actions should the nurse take next?
Correct Answer: C
Rationale: The correct action for the nurse to take next, after confirming the fire, is to evacuate the client. In a fire situation, following the RACE mnemonic, the priority is to rescue or evacuate clients to ensure their safety. Activating the emergency fire alarm (Choice A) is important to alert others and the fire department, but evacuating the client takes precedence. Extinguishing the fire (Choice B) may put the nurse and client at risk and is best left to trained personnel. Confining the fire (Choice D) is not the nurse's responsibility; the focus should be on ensuring the client's safety by evacuating them.
Question 4 of 4
A client has recently started using a behind-the-ear hearing aid. Which of the following statements should the nurse identify as an indication that the client understands the use of this assistive device?
Correct Answer: D
Rationale: The correct answer is D because removing the hearing aid before taking a shower is essential to prevent water damage, as moisture can harm the device. Choice A is incorrect because behind-the-ear hearing aids do allow for fine-tuning of volume. Choice B is incorrect because exercise may cause the hearing aid to shift position, so it's important to ensure it stays secure. Choice C is incorrect because hearing a whistling sound when inserting the hearing aid may indicate improper placement or fit.
