HESI Fundamentals Exam

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: B

Rationale: The most important action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. This action helps prevent obstruction, ensures proper drainage, and reduces the risk of infection. Changing the catheter every 72 hours is not necessary unless clinically indicated and may introduce unnecessary risk. Cleaning the perineal area with antiseptic solution daily is important for general hygiene but not the most critical action for catheter-related infection prevention. Irrigating the catheter with normal saline every shift is not a routine nursing intervention for catheter care and may increase the risk of introducing pathogens.

Correct Answer: C

Rationale: The correct instruction the nurse should include is to rotate injection sites within the same body area. This practice helps prevent lipodystrophy, a condition characterized by the thickening or thinning of subcutaneous fat at the injection sites, which can affect insulin absorption. Choice A is incorrect because administering insulin in the same area each time can lead to lipodystrophy. Choice B is incorrect as insulin should be stored according to the manufacturer's instructions, which may include refrigeration. Choice D is incorrect because the angle of insulin injection (usually 90 degrees) is determined by the length of the needle and the amount of subcutaneous fat, not a fixed 45-degree angle.

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: B

Rationale: Drawing up insulin after warming the vial to room temperature indicates a need for further teaching, as insulin should be at room temperature for administration. Choice A is correct as rotating injection sites helps prevent lipodystrophy. Choice C is correct as pinching the skin helps ensure proper subcutaneous injection. Choice D is correct as injecting insulin at a 90-degree angle is the recommended technique for subcutaneous injections.
