HESI Fundamentals Practice Questions

Correct Answer: A

Rationale: A pull toy is the most appropriate choice for an 18-month-old child. At this age, children are developing their motor skills and coordination, and a pull toy can help with these aspects by encouraging movement and coordination. Puzzle with large pieces (Choice B) may pose a choking hazard for a child of this age due to small parts. While a book with large pictures (Choice C) can be engaging and beneficial for language development, a pull toy is more suitable for promoting physical development in an 18-month-old. A doll with small clothes (Choice D) is not ideal for this age group as small parts can be a choking hazard.

Correct Answer: A

Rationale: The correct answer is to regulate O2 via nasal cannula no more than 6L. This flow rate is generally recommended to ensure adequate oxygen delivery without causing discomfort or potential harm to the patient. Choices B, C, and D are incorrect as they suggest flow rates that are either too low (2L, 4L) or too high (8L). A flow rate of 2L might not provide sufficient oxygen, while 4L could be inadequate for some patients. On the other hand, a flow rate of 8L could be excessive and potentially harmful, leading to complications like oxygen toxicity. Therefore, the optimal recommendation is to regulate O2 via nasal cannula at a maximum of 6L to balance effectiveness and safety.

Correct Answer: A

Rationale: Keeping the client's bed in the lowest position is an essential measure to prevent falls. Lowering the bed reduces the risk of injury if the client falls out of bed by decreasing the distance of the fall. Encouraging the client to wear non-slip socks (Choice B) may help prevent slips on smooth surfaces but does not address the risk of falls in other scenarios. Placing a fall risk sign on the client's door (Choice C) alone does not actively prevent falls but serves as a warning. Using a gait belt when ambulating the client (Choice D) is important for assisting with mobility but does not directly address fall prevention in the client's environment.

Correct Answer: B

Rationale: The correct action for the nurse when assessing the respiratory system for complications of immobility is to auscultate the entire lung region. This approach allows the nurse to identify any diminished breath sounds, crackles, or wheezes that may indicate respiratory issues. Inspecting chest wall movements primarily during the expiratory cycle (Choice A) may not provide a comprehensive assessment of lung sounds. Focusing auscultation on the upper lung fields (Choice C) may miss important findings in the lower lung fields. Assessing the patient at least every 4 hours (Choice D) is important for monitoring overall patient condition but does not specifically address the assessment of respiratory complications related to immobility.

Correct Answer: A

Rationale: The correct statement for the nurse to make to the client is to 'Donate autologous blood before the surgery.' Autologous blood donation involves collecting and storing the client's own blood for potential use during surgery, which significantly reduces the risk of transfusion-related infections. This option directly addresses the client's concern about infection risk. Requesting a specific blood type from a donor (Choice B) is not as effective in reducing infection risk compared to autologous blood donation. Using blood from a family member (Choice C) carries the risk of transfusion reactions and infections due to compatibility issues. Accepting allogeneic blood without concerns (Choice D) does not address the client's specific concern about infection risk and is not the most appropriate option in this situation.
