HESI Fundamentals

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: B

Rationale: When suctioning a tracheostomy, it is crucial to use sterile technique to prevent infections. Turning off the suction as the catheter is introduced is important to avoid trauma and injury to the tracheal walls. This technique helps maintain the integrity of the tracheostomy site and ensures proper care for the patient.

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: 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: 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.
