HESI LPN
Nutrition Final Exam
1. What intervention is recommended for a child with severe dehydration?
- A. Oral rehydration therapy
- B. Intravenous fluid replacement
- C. High-protein diet
- D. Increased physical activity
Correct answer: B
Rationale: Intravenous fluid replacement is the recommended intervention for a child with severe dehydration because it allows for rapid restoration of fluid and electrolyte balance. In severe cases, oral rehydration therapy (Choice A) may not be tolerated due to the child's condition. A high-protein diet (Choice C) is not the primary intervention and does not address the immediate fluid and electrolyte imbalance. Increased physical activity (Choice D) is contraindicated in severe dehydration as it can exacerbate fluid loss, making intravenous fluid replacement the most suitable choice for prompt correction of the severe dehydration.
2. After administering a proton pump inhibitor (PPI), which action should the nurse take to evaluate the effectiveness of the medication?
- A. Ask the client about gastrointestinal pain
- B. Measure the client’s fluid intake and output
- C. Monitor the client’s serum electrolyte levels
- D. Auscultate for bowel sounds in all quadrants
Correct answer: A
Rationale: The correct answer is A: Ask the client about gastrointestinal pain. The effectiveness of a proton pump inhibitor (PPI) is best evaluated by assessing the relief of gastrointestinal symptoms, such as heartburn, acid reflux, or stomach pain. These medications work by reducing the production of stomach acid, so improvement in these symptoms indicates the effectiveness of the PPI. Choices B, C, and D are incorrect because they do not directly reflect the effectiveness of a PPI. Measuring fluid intake and output, monitoring serum electrolyte levels, and auscultating for bowel sounds are important for assessing hydration status, electrolyte balance, and gastrointestinal motility, respectively. However, they are not specific to evaluating PPI effectiveness.
3. A healthcare professional is preparing to administer 750 mL of 0.9% sodium chloride IV to infuse over 7 hr. The professional should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
- A. 107 mL/hr
- B. 120 mL/hr
- C. 95 mL/hr
- D. 100 mL/hr
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.
4. A moderately depressed client who was hospitalized 2 days ago suddenly begins smiling and reporting that the crisis is over. The client says to a nurse, 'I'm finally cured.' The LPN/LVN interprets this behavior as a cue to modify the treatment plan by:
- A. Suggesting a reduction of medication
- B. Allowing increased 'in-room' activities
- C. Increasing the level of suicide precautions
- D. Allowing the client off-unit privileges as needed
Correct answer: C
Rationale: A sudden improvement in mood and declaring being cured can be warning signs of a decision to attempt suicide. Therefore, the appropriate action would be to increase the level of suicide precautions to ensure the safety of the client. This can involve closer monitoring and restriction of items that could be harmful. Choices A, B, and D are incorrect as they do not address the potential risk of suicide that may be present with the sudden change in behavior.
5. The nurse is teaching childbirth preparation classes. One woman asks about her rights to develop a birthing plan. Which response made by the nurse would be best?
- A. "What is your reason for wanting such a plan?"
- B. "Have you talked with your health care provider about this?"
- C. "Let us discuss your rights as a couple."
- D. "Write your ideal plan for the next class."
Correct answer: C
Rationale: Discussing the rights as a couple allows for open communication and helps ensure that the birthing plan aligns with the couple's preferences and medical advice.
