HESI Fundamentals Practice Questions Questions
Question 1 of 5
A healthcare professional is preparing to administer IV fluids to a client. The professional notes sparks when plugging in the IV pump. Which of the following actions should the professional take first?
Correct Answer: B
Rationale: Unplugging the pump is the correct initial action in this situation to prevent any potential fire hazards. Sparks when plugging in the IV pump indicate an electrical issue that can lead to a fire. By immediately unplugging the pump, the healthcare professional ensures the safety of the client and prevents any further risks. Labeling the pump with a defective equipment sticker (Choice A) is not the priority as the immediate concern is safety. Obtaining a replacement pump (Choice C) can be considered after addressing the safety issue. Notifying the maintenance department (Choice D) is important but should follow the immediate action of unplugging the pump to mitigate the risk.
Question 2 of 5
A client with a history of falls is under the care of a nurse. Which of the following actions should the nurse take to prevent falls?
Correct Answer: A
Rationale: Keeping the client's bed in the lowest position is an essential measure to prevent falls. Lowering the bed reduces the risk of injury if the client falls out of bed by decreasing the distance of the fall. Encouraging the client to wear non-slip socks (Choice B) may help prevent slips on smooth surfaces but does not address the risk of falls in other scenarios. Placing a fall risk sign on the client's door (Choice C) alone does not actively prevent falls but serves as a warning. Using a gait belt when ambulating the client (Choice D) is important for assisting with mobility but does not directly address fall prevention in the client's environment.
Question 3 of 5
When teaching a client and their family how to care for the client's tracheostomy at home, which of the following should the nurse include?
Correct Answer: A
Rationale: The correct answer is to use tracheostomy covers when outdoors. This practice helps protect the stoma from foreign particles and temperature changes, reducing the risk of infection. Maintaining a sterile technique when performing tracheostomy care (choice B) is important to prevent infections but is not specific to outdoor care. Removing the outer cannula for routine cleaning (choice C) is not recommended as it may cause trauma or dislodgment of the tracheostomy tube. Cleaning around the stoma with povidone-iodine (choice D) is not advisable as it can be irritating to the skin and may impair the healing process.
Question 4 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 5 of 5
A client in a provider's office tells the nurse that, 'I fast for several days each week to help control my weight.' The client takes several medications for various chronic issues. The nurse should explain to the client that which of the following mechanisms that result from fasting puts her at risk for medication toxicity?
Correct Answer: B
Rationale: Fasting can lead to an increased protein-binding response of medications. This can result in a higher concentration of bound medications in the bloodstream, potentially causing toxicity as the medications may not be readily available for metabolism or excretion. Choice A is incorrect because fasting typically doesn't increase medication metabolism. Choice C is incorrect as fasting usually decreases transit time through the intestines. Choice D is incorrect since fasting generally does not decrease medication excretion.
