1. What is the most effective way to prevent the spread of infection in a healthcare setting?

Correct answer: A

Rationale: Hand hygiene is considered the most effective method to prevent the spread of infection in a healthcare setting. Proper hand hygiene, including washing hands with soap and water or using hand sanitizer, is crucial in reducing the transmission of pathogens from one person to another. While wearing personal protective equipment, sterilizing equipment, and isolating infected patients are also important infection control measures, they are not as universally effective as hand hygiene in preventing the spread of infections. Personal protective equipment can prevent contact with infectious materials, sterilizing equipment reduces the risk of contamination, and isolating infected patients helps prevent the spread of specific infections, but they are more targeted approaches compared to the broad and essential practice of hand hygiene.

2. How should a healthcare provider respond to a patient experiencing a seizure?

Correct answer: D

Rationale: When a patient is experiencing a seizure, the immediate priority is to ensure their safety by placing them in a side-lying position. This helps prevent aspiration in case of vomiting and maintains an open airway. Administering anticonvulsant medications is not within the scope of a healthcare provider's immediate response during a seizure. Applying restraints can potentially harm the patient by restricting movement and causing injury. Monitoring for post-ictal confusion is important after the seizure has ended, but the primary concern during the seizure is ensuring the patient's safety.

3. What are the signs and symptoms of Cushing's syndrome, and how should they be managed?

Correct answer: A

Rationale: The correct signs and symptoms of Cushing's syndrome are weight gain and a moon face. Corticosteroids are used to manage Cushing's syndrome by reducing the overproduction of cortisol. Choice B is incorrect because hirsutism and thin extremities are not typical signs of Cushing's syndrome. Choice C is incorrect as purple striae and muscle weakness are more characteristic of the syndrome. Choice D is also incorrect as hypertension and bruising are not primary signs of Cushing's syndrome.

4. A nurse is teaching a client who is taking warfarin about food and medication interactions. Which of the following foods should the nurse instruct the client to avoid?

Correct answer: D

Rationale: Correct Answer: Green leafy vegetables - Green leafy vegetables are high in vitamin K, which can interfere with the effectiveness of warfarin. Tomatoes, apples, and broccoli are not contraindicated with warfarin therapy. While they are healthy choices, they do not have a significant impact on warfarin's effectiveness.

5. A client diagnosed with hypertension requires lifestyle changes. What change should the nurse emphasize?

Correct answer: B

Rationale: Reducing sodium intake is crucial for managing hypertension as excess sodium can lead to increased blood pressure. High-fat foods (Choice A) are not recommended as they can contribute to heart issues. While dairy products (Choice C) should be consumed in moderation, they are not specifically targeted in hypertension management. High-protein foods (Choice D) are not the priority; rather, reducing sodium intake takes precedence due to its direct impact on blood pressure levels.
