HESI Fundamentals Exam

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.

Correct Answer: A

Rationale: Paralytic ileus is a condition where there is a temporary paralysis of the bowel, leading to absent bowel sounds and abdominal distention. This occurs because the bowel is not functioning properly to propel contents, resulting in a lack of bowel sounds. Absent bowel sounds with distention are typical findings in paralytic ileus. Hyperactive bowel sounds with pain are more indicative of increased motility and are not expected in paralytic ileus. Normal bowel sounds with cramping may be seen in other conditions, such as gastroenteritis. Diminished bowel sounds with tenderness are not typical findings in paralytic ileus.

Correct Answer: A

Rationale: A pericardial friction rub is characterized by a scratching sound that occurs during both systole and diastole. It becomes more distinct when the client is sitting up and leaning forward. This indicates an inflammation of the pericardial sac rubbing against the layers of the heart. Heart murmurs (choice B) are abnormal heart sounds caused by turbulent blood flow, not by friction like in a pericardial rub. S3 and S4 heart sounds (choices C and D) are additional heart sounds related to abnormal ventricular filling, not to pericardial friction rubs.

Correct Answer: C

Rationale: The correct answer is C. This statement reflects the client's understanding of advance directives, as it indicates a specific preference regarding life-sustaining treatment. Advance directives enable individuals to outline their healthcare preferences, including decisions about treatments they wish to receive or avoid. Choice A mentions family members but doesn't address specific healthcare wishes; choice B focuses on the surgery rather than personal directives; choice D discusses doctor approval but lacks details about the directive itself.
