HESI Fundamental Practice Exam

Correct Answer: C

Rationale: The abdomen is the most appropriate site for administering subcutaneous heparin injections. The abdomen has a layer of subcutaneous fat and a good blood supply, making it an ideal site for subcutaneous injections. Using the deltoid muscle for heparin injections is not appropriate as it is typically used for intramuscular injections. The ventrogluteal site is more suitable for intramuscular injections rather than subcutaneous injections. The dorsogluteal site is no longer recommended for injections due to the risk of injury to the sciatic nerve.

Correct Answer: A

Rationale: When admitting a client with an abdominal wound, contact precautions should be implemented. Contact precautions are used to prevent the spread of infections that are spread by direct or indirect contact. In the case of abdominal wounds, bacteria and pathogens can easily be transmitted through contact with the wound or wound drainage. Droplet precautions are used for infections transmitted through respiratory droplets, such as influenza. Airborne precautions are used for infections spread through the air, like tuberculosis. Standard precautions are used for all clients to prevent the spread of infections and should be followed in addition to specific precautions based on the type of infection.

Correct Answer: A

Rationale: Practice sessions are an effective psychomotor approach to learning for adolescents with ostomies as they involve hands-on practice of ostomy care skills, which can help reinforce learning through active engagement. Demonstrations (choice B) can be helpful in providing visual guidance but may not offer the same level of active participation and practice as practice sessions. Written instructions (choice C) may be useful for reference but may not be as effective in developing psychomotor skills. Group discussions (choice D) focus more on verbal exchange and may not directly address the need for hands-on skill development required in managing ostomies. Therefore, practice sessions are the most suitable method for enhancing psychomotor learning in this scenario.

Correct Answer: C

Rationale: Choice C is the correct answer because it demonstrates that the client understands the importance of communicating with the nurse if the pain persists while using the PCA device. This is crucial as it ensures proper pain management and monitoring. Choices A and B are incorrect because delaying the use of the device until necessary or being cautious about pushing the button too much do not necessarily reflect understanding of using the PCA device effectively. Choice D is incorrect as having someone else, like an adult child, push the dose button goes against the principle of the client self-administering the medication through the PCA device.

Correct Answer: B

Rationale: In this scenario, the nurse should adjust the machine settings. If the electronic blood pressure machine is providing varied intervals and inconsistent readings, it indicates a potential malfunction. Changing the settings may help correct the issue and ensure accurate measurements. Discontinuing the machine and measuring manually every 15 minutes (Choice A) may be time-consuming and impractical. Cleaning the machine (Choice C) is important for routine maintenance but may not address the current issue of varied intervals and inconsistent readings. Increasing the frequency of the readings (Choice D) does not address the problem of inaccurate measurements caused by the malfunctioning machine.
