HESI Fundamentals

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.

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: Keeping the drainage system below the level of the chest (C) is crucial to ensure proper drainage and prevent backflow of air or fluid into the chest cavity. This position helps maintain the integrity of the closed drainage system. Ensuring the chest tube remains unclamped at all times (A) allows for continuous drainage. Emptying the chest tube (B) should be done as needed, not routinely every 2 hours. Assessing for subcutaneous emphysema (D) is important but not the most critical action in this scenario.

Correct Answer: A

Rationale: Administering oxygen via a non-rebreather mask is the priority intervention for a client with pulmonary edema to improve oxygenation and address respiratory distress. Adequate oxygenation is essential to support vital organ function. Administering furosemide intravenously, inserting a Foley catheter to monitor urine output, and positioning the client in a high Fowler's position are important interventions but are secondary to ensuring optimal oxygenation in this client with pulmonary edema.

Correct Answer: C

Rationale: The most significant risk factor contributing to arteriosclerosis is excess dietary fat, particularly saturated fat and cholesterol. Therefore, the most crucial brochure for the nurse to provide to the client focuses on decreasing cholesterol levels through diet to help reduce the risk of heart attack or stroke.
