HESI Fundamental Practice Exam

Correct Answer: A

Rationale: Locking the wheels on both the bed and stretcher is crucial for ensuring stability during the transfer process. This action is essential to prevent unexpected movement of the bed or stretcher, reducing the risk of injury to the client and facilitating a safe transfer. Adjusting the bed to a low position is important for the client's comfort and safety but does not directly address the immediate need for stability during the transfer. Asking the client to assist in the transfer may not be feasible immediately postoperatively, depending on their condition and the type of surgery they underwent. Using a transfer sheet without locking the wheels can introduce potential safety hazards as the bed or stretcher may move during the transfer, undermining the stability needed for a safe and effective transfer.

Correct Answer: A

Rationale: The correct intervention is to assist the client back to bed. A decrease in oxygen saturation while ambulating indicates hypoxemia, and the immediate priority is to stabilize oxygen levels. Returning the client to bed allows for rest and decreased oxygen demand, potentially preventing further desaturation. Encouraging continued ambulation (Choice B) may worsen the hypoxemia by increasing oxygen demand. Obtaining portable oxygen (Choice C) is essential but should not delay addressing the low oxygen saturation. Moving the oximetry probe (Choice D) may not address the underlying cause of decreased oxygen saturation and should not be the first intervention.

Correct Answer: A

Rationale: When providing mouth care for an unconscious client, the nurse should turn the client's head to the side. This action helps prevent aspiration by allowing any fluids to drain out of the mouth, reducing the risk of choking or aspiration pneumonia. Placing fingers into the client's mouth can be dangerous and may cause injury. Brushing the client's teeth only once a day may not be sufficient for proper oral hygiene care. Injecting mouth rinse into the center of the mouth is not recommended and can potentially lead to aspiration. Therefore, the correct action for the nurse to take is to turn the client's head to the side.

Correct Answer: A

Rationale: Administering oxygen via a nasal cannula is the priority action for a client experiencing chest pain due to coronary artery disease. Oxygen therapy helps improve oxygenation, reduce myocardial workload, and relieve chest pain by increasing oxygen delivery to the heart muscle. While measuring vital signs, obtaining a 12-lead ECG, and encouraging pursed-lip breathing are important interventions, administering oxygen takes precedence in this situation to address the potential hypoxemia associated with chest pain in a client with a history of coronary artery disease.

Correct Answer: C

Rationale: The correct answer is C. Protecting others from exposure when transporting a client with MRSA is crucial in preventing the spread of infection. This statement demonstrates understanding of infection control measures. Stating that MRSA is usually resistant to vancomycin (choice B) is incorrect; vancomycin is often effective against MRSA. Obtaining a specimen for culture and sensitivity after the first dose of an antimicrobial (choice A) is unnecessary and not indicated. Discontinuing antimicrobial therapy when the client is no longer febrile (choice D) is incorrect because antimicrobial therapy should be completed as prescribed to prevent the development of resistant strains.
