HESI Fundamentals Practice Questions

Correct Answer: A

Rationale: The correct answer is to regulate O2 via nasal cannula no more than 6L. This flow rate is generally recommended to ensure adequate oxygen delivery without causing discomfort or potential harm to the patient. Choices B, C, and D are incorrect as they suggest flow rates that are either too low (2L, 4L) or too high (8L). A flow rate of 2L might not provide sufficient oxygen, while 4L could be inadequate for some patients. On the other hand, a flow rate of 8L could be excessive and potentially harmful, leading to complications like oxygen toxicity. Therefore, the optimal recommendation is to regulate O2 via nasal cannula at a maximum of 6L to balance effectiveness and safety.

Correct Answer: B

Rationale: The correct intervention for a patient diagnosed with osteoporosis and lactose intolerance is to monitor their intake of vitamin D. Since the patient has lactose intolerance, encouraging dairy alternatives (Choice A) would not be appropriate. Increasing intake of caffeinated drinks (Choice C) is not beneficial for managing osteoporosis and may even have negative effects on bone health. Assisting the patient with daily activities (Choice D) is a general nursing intervention that may not directly address the specific needs related to osteoporosis and lactose intolerance.

Correct Answer: B

Rationale: The correct answer is to ensure the client is sitting upright while eating. This position helps prevent aspiration and facilitates swallowing. Offering tart or sour foods (Choice A) may not be suitable for someone with dysphagia as they can be difficult to swallow and may increase the risk of aspiration. Providing soft and easily swallowable foods (Choice C) is crucial for individuals with swallowing difficulties. While giving thickened liquids (Choice D) is a common intervention for dysphagia, the priority during mealtime should be ensuring the client's proper positioning to support safe swallowing and prevent aspiration.

Correct Answer: D

Rationale: The correct answer is D: Blood glucose. Monitoring blood glucose levels is crucial for clients receiving total parenteral nutrition (TPN) due to the high glucose content in TPN solutions. TPN delivers essential nutrients, including glucose, directly into the bloodstream. Clients on TPN are at risk of developing hyperglycemia due to the concentrated glucose infusion. Therefore, close monitoring of blood glucose levels is necessary to detect and prevent hyperglycemia-related complications such as osmotic diuresis, hyperosmolarity, and electrolyte imbalances. While serum sodium, serum calcium, and blood urea nitrogen (BUN) levels are important parameters in various clinical scenarios, they are not specifically associated with TPN administration. These values are not the primary indicators to assess for complications in clients receiving TPN.

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.
