Practice HESI Fundamentals Exam

Correct Answer: A

Rationale: To calculate the infusion rate, divide the total volume (750 mL) by the total time (7 hr). 750 � 7 ≈ 107 mL/hr. Choice A is correct because it accurately calculates the infusion rate based on the total volume and time. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate in this scenario.

Correct Answer: D

Rationale: The first action the nurse should implement is to determine the size and depth of the skin breakdown over the sacral area. This initial assessment will provide crucial information on the extent of the damage and guide appropriate care interventions. Option A is not the priority in this scenario as the immediate concern is addressing the existing skin breakdown. Option B, completing a functional assessment, is important but should come after addressing the acute issue of skin breakdown. Option C, applying a barrier ointment, may be beneficial later but does not address the primary need of assessing the extent of the current skin damage.

Correct Answer: B

Rationale: The LPN/LVN should first obtain the nutritional history in this scenario. Nutrition plays a crucial role in mental health, and deficiencies or imbalances in diet can contribute to anxiety symptoms. Understanding the mother's nutritional intake can help identify any factors exacerbating her anxiety. Sexual activity patterns are not directly relevant to her anxiety symptoms unless specifically indicated. Leisure activities and financial stressors may be important but are secondary to addressing the potential impact of nutrition on anxiety.

Correct Answer: B

Rationale: The correct answer is B. Flossing is essential for removing plaque and tartar between teeth, contributing to better oral hygiene. Choice A is not entirely accurate as waxed floss may not solely prevent bleeding. Flossing three times a day, as mentioned in choice C, can be excessive and unnecessary, while choice D is incorrect as applying toothpaste before flossing is not harmful but might not provide additional benefits.

Correct Answer: B

Rationale: The correct answer is B. Scheduling routine health care visits, even when feeling well, is crucial for early detection and prevention of health issues. This proactive approach allows healthcare providers to monitor overall health, provide preventive care, and address any emerging health concerns promptly. Choice A is incorrect because past immunizations do not cover all potential diseases; regular check-ups are still necessary. Choice C is incorrect as urgent care centers are not designed for routine medical care. Choice D is incorrect as seeking help for stress is important for mental well-being and should not be dismissed as a normal part of life.
