HESI LPN
Adult Health 1 Final Exam
1. Which membrane lines the abdominal cavity?
- A. Perineum
- B. Pericardium
- C. Pleura
- D. Peritoneum
Correct answer: D
Rationale: The correct answer is D, Peritoneum. The peritoneum is the membrane that lines the abdominal cavity, providing support to abdominal organs and serving as a conduit for their blood vessels. Choices A, B, and C are incorrect. The perineum refers to the area between the anus and the external genitalia, the pericardium is the membrane enclosing the heart, and the pleura is the membrane surrounding the lungs.
2. A client with a history of chronic obstructive pulmonary disease (COPD) is prescribed oxygen therapy at 2 liters per minute via nasal cannula. What is the most important instruction the nurse should provide?
- A. Increase the oxygen flow rate if shortness of breath occurs
- B. Use oxygen only when experiencing shortness of breath
- C. Do not adjust the oxygen flow rate without consulting a healthcare provider
- D. Use a humidifier with the oxygen to prevent dry mucous membranes
Correct answer: C
Rationale: The most important instruction the nurse should provide to a client with COPD prescribed oxygen therapy is not to adjust the oxygen flow rate without consulting a healthcare provider. This is crucial because too much oxygen can suppress the client's respiratory drive, leading to further complications. Choice A is incorrect because increasing the oxygen flow rate without medical advice can be harmful. Choice B is incorrect as oxygen therapy should be used as prescribed, not just when symptoms occur. Choice D is incorrect as the priority is to ensure the correct oxygen flow rate rather than using a humidifier.
3. A client with a history of peptic ulcer disease (PUD) is prescribed omeprazole (Prilosec). What is the primary action of this medication?
- A. Neutralizes stomach acid
- B. Reduces gastric acid production
- C. Forms a protective barrier over ulcers
- D. Increases gastric mucus production
Correct answer: B
Rationale: The correct answer is B: Reduces gastric acid production. Omeprazole is a proton pump inhibitor that works by reducing gastric acid production, thereby helping to heal ulcers. While neutralizing stomach acid is associated with antacids, forming a protective barrier over ulcers is more characteristic of medications like sucralfate. The action described in choice D, increasing gastric mucus production, is not the primary mechanism of action of omeprazole in treating peptic ulcer disease.
4. What are the final factors that contribute to blood pressure? (Select all that apply)
- A. Heart rate
- B. Stroke volume
- C. Peripheral resistance
- D. Neuroendocrine hormones
Correct answer: D
Rationale: Neuroendocrine hormones play a crucial role in regulating blood pressure by influencing factors like fluid balance, blood volume, and vessel constriction. While heart rate, stroke volume, and peripheral resistance are important factors affecting blood pressure, the final parameters that directly produce blood pressure are influenced by neuroendocrine hormones. Therefore, choice D is the correct answer. Choices A, B, and C are involved in the regulation of blood pressure but are not the final parameters that directly produce it.
5. The nurse is providing discharge teaching to a client with newly diagnosed type 2 diabetes mellitus. Which instruction is most important to prevent complications?
- A. Monitor blood glucose levels regularly
- B. Maintain a low-fat diet
- C. Exercise regularly
- D. Take medication as prescribed
Correct answer: A
Rationale: Regular monitoring of blood glucose levels is crucial in managing diabetes and preventing complications. This allows the client and healthcare team to make timely adjustments to the treatment plan. While maintaining a low-fat diet, exercising regularly, and taking medication as prescribed are all important aspects of diabetes management, monitoring blood glucose levels takes precedence as it provides real-time information about the client's condition and helps prevent acute complications.
