HESI LPN
Adult Health 1 Final Exam
1. A client with diabetes mellitus is scheduled for surgery. What is the most important preoperative instruction the nurse should provide?
- A. Take your insulin as usual
- B. Do not eat or drink after midnight
- C. Monitor your blood glucose closely
- D. Bring your glucose meter to the hospital
Correct answer: B
Rationale: The most important preoperative instruction for a client with diabetes mellitus scheduled for surgery is to instruct them not to eat or drink after midnight. This instruction is crucial to maintain NPO (nothing by mouth) status before surgery, reducing the risk of aspiration during anesthesia. While taking insulin as usual (Choice A) is important, doses can be adjusted by the healthcare team. Monitoring blood glucose closely (Choice C) is essential but not as critical preoperatively. Bringing a glucose meter to the hospital (Choice D) can be helpful but is not as vital as maintaining NPO status.
2. In the scientific method, a tentative solution to a problem is called a what?
- A. theory
- B. prediction
- C. hypothesis
- D. correlation
Correct answer: C
Rationale: In the scientific method, a hypothesis is a tentative solution or educated guess that is tested through research. A theory (choice A) is a well-substantiated explanation based on evidence and extensive testing. A prediction (choice B) is a statement about what will happen in the future based on existing knowledge. Correlation (choice D) refers to a mutual relationship between two or more things, indicating how they may change together but not providing a solution to a problem.
3. When caring for a child diagnosed with asthma, what is an important nursing intervention?
- A. Administering bronchodilators
- B. Encouraging physical activity
- C. Monitoring oxygen saturation
- D. Providing nutritional support
Correct answer: A
Rationale: Administering bronchodilators is a crucial nursing intervention for a child with asthma as it helps to open the airways and improve breathing. Bronchodilators work by relaxing the muscles around the airways, making breathing easier for the child. Encouraging physical activity may exacerbate asthma symptoms in some cases, so it is not recommended as a primary intervention. Monitoring oxygen saturation is important in assessing respiratory status, but administering bronchodilators would take precedence in this situation. Providing nutritional support is a general nursing intervention and not specific to managing asthma symptoms.
4. A client with gastroesophageal reflux disease (GERD) is prescribed omeprazole. The nurse should reinforce which instruction?
- A. Take this medication in the morning before breakfast.
- B. Take this medication with meals.
- C. Avoid taking this medication with antacids.
- D. Take this medication at bedtime.
Correct answer: A
Rationale: The correct instruction for a client with GERD prescribed omeprazole is to take the medication in the morning before breakfast. Omeprazole works best when taken on an empty stomach, approximately 30 minutes before the first meal of the day. This timing maximizes its effectiveness in reducing stomach acid production and helps manage symptoms of GERD more efficiently. Choice B is incorrect because taking omeprazole with meals may reduce its efficacy as it needs an empty stomach for optimal absorption. Choice C is incorrect because omeprazole can be taken with or without food, but it should not be taken with antacids as they can affect its absorption. Choice D is incorrect because taking omeprazole at bedtime is less effective compared to taking it before breakfast due to the circadian rhythm of gastric acid secretion.
5. Which nursing intervention provides the most support to the parents of an infant with an obvious physical anomaly?
- A. Encourage them to express their concerns.
- B. Discourage them from talking about their baby.
- C. Assure them not to worry because the anomaly can be repaired.
- D. Show them postoperative photographs of infants who had a similar anomaly.
Correct answer: A
Rationale: Encouraging parents to express their concerns is the most supportive intervention because it allows them to process their emotions and provides them with an opportunity to share their fears, anxieties, and questions. This open communication helps the nurse to offer appropriate support, education, and reassurance. Discouraging parents from talking about their baby (Choice B) can hinder their emotional expression and prevent them from seeking necessary information and support. Assuring parents not to worry (Choice C) may invalidate their feelings and minimize the significance of their concerns. Showing postoperative photographs (Choice D) may not be appropriate at this stage as parents need emotional support and education about the current situation before focusing on postoperative outcomes.
