HESI Fundamentals Practice Questions

Correct Answer: A

Rationale: In this scenario, the nurse should stand to the side of the patient's eye and observe the cornea. This action is crucial in assessing whether the patient wears contact lenses, especially in unresponsive patients. Observing the cornea can provide valuable information about the patient's eye health and potential use of contact lenses. Choices B, C, and D are incorrect. Concluding that the glasses were lost during the accident is premature without proper assessment. Notifying ambulance personnel about the missing glasses may not be the immediate priority, and asking the unresponsive patient about the glasses would not yield useful information in this situation.

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.

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.

Correct Answer: C

Rationale: The correct answer is C because ginkgo biloba is commonly used to help with headaches, among other benefits. Choices A, B, and D are incorrect because garlic is not typically used for menopausal symptoms, ginger is mainly used for nausea and vomiting (not car sickness specifically), and echinacea is not known to control cholesterol.

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.
