HESI Fundamentals Exam

Correct Answer: B

Rationale: The correct answer is B: Bruit. A bruit is a blowing sound indicating turbulent blood flow, often heard over the aorta. Choices A, C, and D are incorrect. A gallop is a cardiac sound resembling the sound of a galloping horse. A thrill is a vibration felt on palpation, and a murmur is a swooshing or whooshing sound heard during auscultation of the heart or blood vessels. In this scenario, the blowing sound over the aorta specifically indicates a bruit, which signifies turbulent blood flow and should be further assessed by the healthcare provider.

Correct Answer: C

Rationale: The correct answer is C: Back. Back injuries are common among healthcare workers, especially nurses, due to improper lifting techniques and bending. Working on an orthopedic rehabilitation unit involves frequent lifting and positioning of patients, putting the nurse at risk of back injuries. Preventing back injuries is crucial for maintaining the nurse's health and ability to provide care effectively. Choices A, B, and D are incorrect because while lifting and positioning patients may involve these body parts, back injuries are most likely to occur due to the strain and stress placed on the back during such activities.

Correct Answer: A

Rationale: To maintain patency of the NG tube, it is essential to irrigate the tube with normal saline every shift. This action helps prevent clogging and ensures that the tube remains clear for effective decompression. Checking tube placement by auscultation (Choice B) is important for verifying correct placement but does not directly impact patency. Securing the tube to the client's gown (Choice C) is crucial for safety and comfort but is not directly related to maintaining patency. Flushing the tube with sterile water before and after medication administration (Choice D) is not the recommended method for maintaining patency of an NG tube, as normal saline is the appropriate solution for this purpose.

Correct Answer: A

Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.
