Practice HESI Fundamentals Exam

Correct Answer: D

Rationale: The correct answer is D: 'Carbon monoxide binds with hemoglobin in the body.' Carbon monoxide is an odorless, colorless gas, so it does not have a distinct odor (Choice A). While regular inspection of appliances like water heaters is important for safety, it is not directly related to carbon monoxide poisoning (Choice B). Carbon monoxide primarily affects the cardiovascular system by binding with hemoglobin, reducing the blood's ability to carry oxygen, rather than causing direct lung damage (Choice C). Understanding how carbon monoxide binds with hemoglobin is crucial in recognizing the mechanism of poisoning and its potential consequences.

Correct Answer: C

Rationale: The nurse who transferred the client to the chair when the fall occurred is directly involved in the event that led to the injury. Improper transfer techniques or lack of appropriate precautions during the transfer could have contributed to the fall and subsequent fracture of the hip. This direct involvement makes this nurse the one at greatest risk for a malpractice judgment. Choices A, B, and D are not as directly linked to the event that caused the injury. While poor nursing notes could be a factor, it is the immediate action of transferring the client that has a more direct impact on the client's fall and subsequent injury.

Correct Answer: B

Rationale: The correct answer is B. Clients with GERD should avoid coffee as it can relax the lower esophageal sphincter and exacerbate symptoms. Limiting coffee consumption to the morning hours may not be sufficient, as coffee can still contribute to GERD symptoms throughout the day. Choices A, C, and D are all appropriate strategies for managing GERD symptoms. Avoiding large meals before bedtime, elevating the head of the bed while sleeping, and steering clear of spicy and acidic foods are all recommended practices to help alleviate GERD symptoms. Therefore, the client's statement in option B indicates a need for further teaching to completely address dietary modifications for managing GERD.

Correct Answer: C

Rationale: The correct first action for the school nurse to take when a child is injured and appears to have a fractured leg is to assess the child and the extent of the injury. This initial assessment is crucial to determine the severity of the injury before proceeding with further interventions. Option A, calling for emergency transport, should only be done after assessing the extent of the injury. Option B, immobilizing the limb and joints, is important but should come after the initial assessment. Option D, applying cold compresses, is not recommended for suspected fractures as it can exacerbate swelling and pain.

Correct Answer: A

Rationale: The correct answer is to use the complete name of the medication magnesium sulfate. This is important to prevent confusion with morphine sulfate, which is abbreviated as MSO4. Choice B is incorrect as it is essential to maintain a space between the numerical dose and the unit of measure for clarity in medication documentation. Choice C is incorrect as the standard abbreviation for units is 'U' for international units, not for the dosage of insulin. Choice D is incorrect as the appropriate abbreviation for subcutaneous injection is 'SC,' not just 'SC.' Therefore, the nurse manager should emphasize using the full name of medications to avoid errors and ensure patient safety.
