HESI Fundamentals Practice Questions

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 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.

Correct Answer: D

Rationale: Information about transmission-based precautions is essential for infection control and continuity of care.

Correct Answer: D

Rationale: After confirming unresponsiveness and calling for help, the next step in basic life support is to open the client's airway. This ensures that the airway is clear and allows for effective ventilation. Checking the carotid pulse is not necessary at this stage as airway management takes precedence. Delivering abdominal thrusts is not indicated for an unresponsive client as it is for conscious choking individuals. Giving rescue breaths should only be done after ensuring the airway is open to allow for effective ventilation.

Correct Answer: A

Rationale: Using tracheostomy covers when outdoors is essential to protect the tracheostomy from dust and debris, reducing the risk of infection. Tracheostomy covers help maintain cleanliness and prevent foreign particles from entering the stoma. Choice B is incorrect because cleaning the tracheostomy with alcohol can be too harsh and drying for the skin surrounding the stoma, leading to skin irritation. Choice C is incorrect as tracheostomy tubes are typically replaced only when clinically indicated or as per the healthcare provider's instructions, not routinely every week, to prevent unnecessary risks and complications. Choice D is incorrect as covering the tracheostomy with a wet cloth when sleeping can create a moist environment ideal for bacterial growth, increasing the risk of infection and skin breakdown. It is important to keep the tracheostomy site clean, dry, and protected to maintain optimal hygiene and prevent complications.
