HESI Fundamentals Practice Questions

Correct Answer: A

Rationale: Instructing the client to follow a finger through the six cardinal positions of gaze is the correct action when assessing extraocular eye movements. This technique assesses the movement of the eyes in all directions and helps to test cranial nerves 3, 4, and 6, which control eye movements. Choice B is incorrect as the distance mentioned is not relevant for assessing extraocular eye movements. Choice C is incorrect as both eyes need to be assessed independently. Choice D is incorrect as positioning the client 6.1 m (20 feet) away from the Snellen chart is related to visual acuity testing, not extraocular eye movements.

Correct Answer: B

Rationale: The correct action in this scenario is to disconnect the electronic blood pressure machine and measure the client's blood pressure manually every 15 minutes. Given that the machine is malfunctioning and providing inconsistent readings, relying on manual measurements ensures accuracy and maintains the quality of care. Notifying the manufacturer (Choice A) may be necessary in the long run, but the immediate concern is the accuracy of the vital signs. Adjusting the machine settings again (Choice C) without resolving the underlying issue would not address the problem. Ignoring the extra readings (Choice D) could lead to incorrect assessment and compromise patient care. Therefore, the best course of action is to disconnect the machine and opt for manual blood pressure measurements until the issue is resolved.

Correct Answer: A

Rationale: The correct answer is A: Temperature. A high temperature of 39.2�C (102�F) indicates a fever, which can be a sign of infection or another serious condition. Investigating the cause of the fever is a priority to address any underlying health issue promptly. Menses overdue (choice B) could be relevant but is not as urgent as addressing a fever. A soft tender abdomen (choice C) is important but may be a consequence of the underlying condition causing the fever. Heart rate (choice D) is also significant, but the priority here is to identify the cause of the fever.

Correct Answer: C

Rationale: Suctioning the tracheostomy tube as needed is the most appropriate action in this scenario. When a client with a tracheostomy is unable to clear secretions by coughing, suctioning helps remove the excess secretions from the airway, ensuring proper breathing. Encouraging deep breaths (Choice A) may not effectively address the immediate need to clear secretions. Providing humidified oxygen (Choice B) can help with oxygenation but does not directly address the issue of clearing secretions. Changing the tracheostomy dressing daily (Choice D) is important for maintaining cleanliness but is not the priority when the client is unable to clear secretions.

Correct Answer: B

Rationale: Placing the client's arm in a dependent position is the correct action when inserting a peripheral IV catheter for an older adult client. This position helps veins dilate due to gravity, facilitating easier insertion of the IV catheter. Choice A is incorrect because catheters are typically inserted at a lower angle, around 10-30 degrees. Choice C is unnecessary unless excessive hair impedes the insertion process. Choice D is incorrect as veins in the hand are generally smaller and more prone to complications, making them less ideal for IV therapy in older adults.
