HESI Fundamentals Practice Questions

Correct Answer: A

Rationale: The correct answer is A. Introducing solid foods one at a time, starting with cereal, is recommended to monitor for any food allergies or intolerances in infants. Choice B is incorrect as finely ground meat should be introduced later due to the risk of choking and is not necessary for iron intake. Choice C is incorrect as egg white should be avoided early due to the risk of allergies. Choice D is incorrect as solid foods should not be mixed with formula in a bottle to prevent overfeeding and promote healthy eating habits.

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.

Correct Answer: A

Rationale: The correct action to take first when observing blue fingers in a client with wrist restraints is to loosen the right wrist restraint. Blue fingers indicate compromised circulation, and loosening the restraint can help restore blood flow to the area. Applying a pulse oximeter (Choice B) or palpating the right radial pulse (Choice D) may be necessary following the loosening of the restraint to assess the client's oxygen saturation and pulse. Comparing hand color bilaterally (Choice C) is important but not the immediate action needed when a circulation issue is noted in one hand.

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: The correct answer is to continue monitoring the patient as instructed. This is crucial to assess the patient's condition and response to initial interventions. Administering IV fluids or preparing for transfer to the ICU should only be done based on further assessment or explicit orders from the healthcare provider. Notifying the nurse manager, as suggested in choice A, without further assessment or intervention could delay immediate patient care and management.
