HESI Fundamentals Exam

Correct Answer: A

Rationale: Using soft blankets to secure to the side rails provides better protection during a seizure as they are more secure and less likely to shift compared to pillows. This action helps prevent injury to the client by minimizing the risk of falling or hitting the side rails during a seizure. Choices B and C do not address the issue of using more secure materials. Choice D is inappropriate as it is important for the nurse to ensure the safety and well-being of the client by using the most appropriate protective measures.

Correct Answer: A

Rationale: Performing a bladder scan is the initial step to assess for urinary retention in a postoperative client. This non-invasive technique helps determine the volume of urine in the bladder, guiding further interventions. Encouraging the client to drink fluids (Choice B) may be beneficial but is not the priority when assessing for urinary retention. Inserting a straight catheter (Choice C) should not be the initial action without first assessing for retention. Administering a diuretic (Choice D) should not be done without confirming the need through assessment.

Correct Answer: A

Rationale: The most critical action for the nurse to take when a client with diabetes mellitus presents with symptoms of hyperglycemia such as polyuria, polydipsia, and polyphagia is to monitor the client's blood glucose level. This action helps in assessing the client's current glycemic status and guides further interventions. Encouraging increased fluid intake (Choice B) may be beneficial in managing dehydration caused by polyuria, but it does not address the underlying cause of hyperglycemia. Administering insulin as prescribed (Choice C) may be necessary based on the blood glucose monitoring results, but monitoring should precede any medication administration. Assessing the client's urine output (Choice D) is important but does not directly address the primary concern of evaluating and managing hyperglycemia in a client with diabetes.

Correct Answer: D

Rationale: The correct answer is D: "I will listen for background noises." Listening for background noises can provide useful information about the bomb's location, helping security to assess the situation more effectively. Choice A is incorrect because disconnecting the call abruptly may prevent gathering important details. Choice B is incorrect as using elevators during a bomb threat can be dangerous; it is safer to use stairs for evacuation. Choice C is incorrect because actively engaging with the caller to gather information is crucial in bomb threat situations.

Correct Answer: B

Rationale: The toddler with severe deep abrasions covering 98% of the body would be prioritized for treatment last because these extensive injuries may require immediate attention and resources. The other choices present serious conditions but are not as severe or life-threatening as the toddler's injuries. The infant with an intermittent bulging anterior fontanel may have signs of increased intracranial pressure, requiring prompt evaluation. The preschooler's fractures, though serious, can be managed without immediate critical intervention. The school-age child with singed eyebrows and hair may have suffered burns but does not exhibit injuries as severe as the toddler's deep abrasions.
