HESI Fundamentals

Correct Answer: A

Rationale: To calculate the mL to administer, divide the ordered dose (3 mg) by the concentration (4 mg/mL). 3 mg � 4 mg/mL = 0.75 mL. Rounding to the nearest tenth, the correct dose to administer is 0.8 mL.

Correct Answer: D

Rationale: The priority action for the nurse in this situation is to gently lower the client to the floor. This action helps prevent injury to both the client and the nurse. It is important to ensure a safe environment and protect the client from falling, as well as to maintain the nurse's own safety while providing care.

Rationale: The presence of numerous scatter rugs throughout the house poses a significant safety hazard to the client who is ambulating with a quad cane. These rugs increase the risk of tripping and falling, making it the most critical finding that needs immediate attention to prevent potential injuries and ensure the client's safety during ambulation.

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: 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.
