HESI Fundamentals

Correct Answer: C

Rationale: An elevated AST level following chest pain and shortness of breath is suggestive of myocardial infarction. AST is released from damaged heart muscle cells during a heart attack, indicating cardiac involvement. This enzyme is not specific to liver disease, gallbladder disease, or skeletal muscle injury in this clinical context.

Correct Answer: C

Rationale: A potassium level of 5.5 mEq/L (C) is elevated and concerning in a client with renal failure receiving hemodialysis, as it can lead to life-threatening cardiac arrhythmias. Monitoring blood pressure (A), weight gain (B), and weight loss (D) are essential in clients on hemodialysis, but an elevated potassium level poses an immediate risk that requires prompt intervention.

Correct Answer: D

Rationale: The correct answer is D because emptying a urinary catheter drainage bag exposes the nurse to body fluids, necessitating the use of barrier gloves as per Standard Precautions to prevent potential infection transmission.

Correct Answer: D

Rationale: Purulent drainage indicates infection at the insertion site, which requires immediate attention to prevent complications.

Correct Answer: B

Rationale: The correct answer is to put bed rails up on the side of the bed opposite from the nurse. This action is essential to prevent the client from falling out of bed during the turning process. Since the nurse can only stand on one side of the bed, having the bed rails up on the opposite side provides an additional safety measure. Securing the client's arm and leg or lowering the head of the bed would not prevent the client from falling and may pose a risk of injury. Using a turn sheet correctly can be helpful, but ensuring the bed rails are up is a more direct safety measure in this situation.
