HESI Practice Test for Fundamentals

Correct Answer: A

Rationale: The nurse's priority is to ensure that the client signs the consent form before the hip surgery. This is crucial as it ensures that the client has provided informed consent for the procedure. Locking valuables, verifying lab values, and administering sedatives are important tasks but ensuring consent takes precedence as it directly impacts the client's right to make decisions about their care.

Correct Answer: B

Rationale: The correct answer is B: Mitral stenosis. A high-pitched scratching sound heard during both systole and diastole with the diaphragm of the stethoscope positioned at the left sternal border indicates mitral stenosis, not a pericardial friction rub. Pericardial friction rub is a to-and-fro, grating, or scratching sound due to inflamed pericardial surfaces rubbing together, typically heard in early diastole and late systole. Aortic regurgitation and tricuspid stenosis would present with different auscultatory findings compared to the described scenario, making them incorrect choices in this context.

Correct Answer: A

Rationale: The correct precaution for Shigella infection is to wash hands thoroughly before and after contact with the client. Shigella is transmitted through the fecal-oral route, so hand hygiene is crucial in preventing its spread. Wearing a surgical mask or face shield is not necessary for Shigella as it is not primarily transmitted through respiratory droplets. While wearing a gown and gloves is important for standard precautions, the key precaution specific to Shigella is proper hand hygiene.

Correct Answer: B

Rationale: The correct answer is Fowler's position. Placing the client in Fowler's position, with the head of the bed elevated to 45-60 degrees, reduces the risk of aspiration during bolus enteral feedings by facilitating the flow of the feeding into the stomach. Prone position (choice A) is lying face down, which is not suitable for feeding. Sims' position (choice C) is a side-lying position used for rectal examinations or enemas, not for feeding. Supine position (choice D) is lying flat on the back and is not optimal for reducing the risk of aspiration during bolus tube feedings.

Correct Answer: B

Rationale: When caring for a client with tuberculosis (TB), airborne precautions should be implemented. Tuberculosis is spread through the air via droplet nuclei, requiring the use of airborne precautions to prevent the transmission of the infection. Droplet precautions are used for diseases spread by large respiratory droplets, such as influenza or pertussis. Contact precautions are used for diseases that spread through direct contact, such as MRSA. Standard precautions are used for all clients to prevent the transmission of infections from blood, body fluids, non-intact skin, and mucous membranes.
