HESI Fundamentals Exam

Correct Answer: A

Rationale: Choice A is correct because performing ankle and knee exercises every hour helps prevent contractures and other adverse effects of immobility. Contractures are a common complication of immobility, and range of motion (ROM) exercises can help maintain joint flexibility and prevent contractures. This statement indicates an understanding of the teaching provided by the healthcare provider. Choices B, C, and D are incorrect. Holding the breath when rising from a sitting position can increase the risk of orthostatic hypotension, not reduce adverse effects of immobility. Removing antiembolic stockings while in bed can compromise their effectiveness in preventing deep vein thrombosis (DVT), which is not a measure to reduce immobility-related complications. Having a partner help change positions every 4 hours may not be frequent enough to prevent immobility-related complications effectively; changing positions more frequently is usually recommended to prevent issues like pressure ulcers and muscle stiffness.

Correct Answer: C

Rationale: The nurse's priority should be to eliminate safety hazards from the client's environment as it directly reduces the risk of falls. Addressing environmental hazards is an immediate and crucial step in preventing falls. While completing a fall-risk assessment is important to understand the client's risk factors, educating the client and family about fall risks is essential for prevention, and ensuring the use of assistive aids is crucial for safety, eliminating safety hazards takes precedence as it directly mitigates the risk of falls.

Correct Answer: C

Rationale: To calculate the drops per minute for the IV infusion, first determine the total drops to be infused over 8 hours. 1,000 ml to be infused over 8 hours means 125 ml per hour (1000 ml / 8 hours = 125 ml/hr). Since the infusion set delivers 10 drops per ml, 125 ml/hr x 10 drops/ml = 1250 drops/hr. To find drops per minute, divide the drops per hour by 60 (minutes in an hour): 1250 drops/hr / 60 minutes = 20.83 drops/minute, which rounds up to 21 drops per minute (Option C). This rate ensures the correct infusion rate over 8 hours. Choices A, B, and D are incorrect calculations and do not provide the appropriate infusion rate needed to administer the IV over the specified time period.

Correct Answer: D

Rationale: Gingival hyperplasia is a significant side effect associated with phenytoin therapy. It is characterized by an overgrowth of gum tissue, which can lead to issues such as difficulty in speaking, eating, and maintaining proper oral hygiene. This condition can progress rapidly and may require immediate intervention by the healthcare provider to prevent further complications. Increased appetite, dry mouth, and nausea/vomiting are common side effects of various medications, but they are not as urgent or serious as gingival hyperplasia in a client taking phenytoin.

Correct Answer: A

Rationale: The correct action for the LPN/LVN to implement is to give an around-the-clock schedule for administration of analgesics. This approach helps maintain consistent pain management by providing the medication regularly, preventing the pain from becoming severe. Choice B is incorrect because waiting for severe pain before administering the analgesic may lead to uncontrolled pain levels. Choice C is inappropriate as the goal of pain management in hospice care is to provide comfort without unnecessary sedation. Choice D is also incorrect as offering a medication-free period may result in inadequate pain control for the client.
