HESI Fundamentals Exam

Correct Answer: D

Rationale: The correct answer is to check the IV tubing for obstruction. The first step in the nursing process is assessment. By checking the IV tubing for obstruction, the nurse can assess and potentially correct any issues affecting the flow rate. This action may help to ensure that the prescribed infusion rate is maintained. Repositioning the client is not the priority at this stage as the issue seems related to the IV tubing. Documenting the intake or requesting a new prescription are not immediate actions needed to address the current situation with the IV fluid flow.

Correct Answer: C

Rationale: The correct answer is C: Skim milk, turkey salad, roll, and vanilla ice cream. These items are low in sodium, making it a suitable meal for someone on a low-sodium diet. Skim milk, turkey salad, and vanilla ice cream are naturally low in sodium, while the roll can be selected as a low-sodium option. Choices A, B, and D contain items that are typically high in sodium, such as bacon, clam chowder, crackers, and cheese, making them unsuitable for a low-sodium diet.

Correct Answer: C

Rationale: The correct answer is C: Back. Back injuries are common among healthcare workers, especially nurses, due to improper lifting techniques and bending. Working on an orthopedic rehabilitation unit involves frequent lifting and positioning of patients, putting the nurse at risk of back injuries. Preventing back injuries is crucial for maintaining the nurse's health and ability to provide care effectively. Choices A, B, and D are incorrect because while lifting and positioning patients may involve these body parts, back injuries are most likely to occur due to the strain and stress placed on the back during such activities.

Correct Answer: C

Rationale: The correct answer is C: Bradycardia. Beta-blockers are medications that can lower heart rate, leading to bradycardia as a potential side effect. It is essential for the LPN/LVN to monitor for this adverse effect due to the medication's mechanism of action. Choices A, B, and D are incorrect because increased appetite, dry mouth, and insomnia are not typically associated with beta-blocker use. Monitoring for bradycardia is crucial to ensure patient safety and to prevent any potential complications.

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.
