HESI Fundamentals

Correct Answer: D

Rationale: Central venous pressure (CVP) monitoring is the most effective method to assess fluid status and the cardiovascular system in a client with severe burns. Severe burns can lead to significant fluid shifts and hemodynamic changes, making central venous pressure monitoring crucial for guiding fluid resuscitation and managing cardiovascular stability in these patients.

Correct Answer: C

Rationale: Suctioning the patient in a supine position and pulling the bed sheets tightly across their feet can lead to foot drop, which is harmful for a patient with right-sided hemiplegia. This action can exacerbate muscle weakness and impair circulation in the affected limb. It is crucial to avoid actions that may compromise the patient's safety and well-being, such as causing foot drop in this scenario.

Correct Answer: A

Rationale: The most crucial nursing action when assisting an older adult client with a tub bath is to check the bath water temperature. This step is essential to prevent burns from hot water or chilling from water that is too cold. Ensuring the water temperature is safe is a critical aspect of promoting the client's safety and comfort during the bathing process.

Correct Answer: D

Rationale: When inserting an indwelling catheter, the nurse must observe sterile technique to minimize the risk of infections. Sterile technique involves using sterile equipment and maintaining a sterile field to prevent introducing pathogens into the urinary tract.

Correct Answer: B

Rationale: Edema in the fingers and hands can impede the proper functioning of the pulse oximeter, leading to a falsely low oxygen saturation reading. Edema alters the transmission of light through the tissues, affecting the accuracy of the measurement. Therefore, the presence of edema in the fingers and hands is the most likely factor contributing to the low oxygen saturation reading of 91%.
