Correct Answer: B

Rationale: The correct answer is B: Scheduled analgesia should be administered around-the-clock to prevent pain. After undergoing a wide excision of the vulva, the patient is likely to experience significant pain. Scheduled analgesia ensures that the patient receives pain relief consistently, preventing pain from becoming severe. This approach helps to maintain a therapeutic level of pain control and improves patient comfort and satisfaction. Choice A is incorrect because withholding analgesia until the pain becomes unbearable can lead to unnecessary suffering and poor pain management. Choice C is incorrect as PRN dosing may result in inadequate pain relief and fluctuations in pain control. Choice D is incorrect as opioids are often necessary for postoperative pain management, and NSAIDs alone may not provide sufficient relief for the level of pain associated with a wide excision surgery.

Correct Answer: C

Rationale: Step 1: The nurse should inform the patient that most cases of ovarian cancer are considered to be random, with no obvious causation. This is the correct answer because the exact cause of ovarian cancer is not well understood, and the majority of cases are not linked to specific risk factors. Step 2: Choice A is incorrect because the use of oral contraceptives actually decreases the risk of ovarian cancer. Step 3: Choice B is incorrect because tobacco use is not a major risk factor for ovarian cancer. It is primarily associated with lung and other types of cancer. Step 4: Choice D is incorrect because while a family history of ovarian cancer can increase the risk, the majority of women diagnosed with ovarian cancer do not have a family history of the disease.

Correct Answer: B

Rationale: Correct Answer: B - Eat fish at least 5 times per week. Rationale: 1. Fish is rich in omega-3 fatty acids, which are beneficial for heart health. 2. Eating fish frequently can help reduce the risk of cardiovascular diseases. 3. Consuming fish aligns with dietary recommendations for cardiovascular health. Summary of Incorrect Choices: A: Maintaining carbohydrate intake is important, but it may not specifically indicate success in cardiovascular disease management. C: Limiting trans fats is crucial, but it alone may not indicate overall success in dietary management for cardiovascular disease. D: Avoiding high-fiber foods is not recommended, as fiber is beneficial for heart health and overall well-being.

Correct Answer: B

Rationale: The correct answer is B: Stapes. Otosclerosis is a condition characterized by abnormal bone growth in the middle ear, causing the stapes bone to become fixed in place. This results in hearing loss due to the inability of the stapes to transmit sound vibrations to the inner ear. The malleus (choice A), incus (choice C), and tympanic membrane (choice D) are not primarily affected by otosclerosis. The malleus and incus are located in the middle ear but are not typically affected by otosclerosis. The tympanic membrane is part of the outer ear and is not directly involved in otosclerosis.

Correct Answer: A

Rationale: The correct answer is A: Rinsing the ears with normal saline after swimming. This is because rinsing with normal saline helps to remove excess moisture and debris, preventing bacterial growth that can lead to otitis externa. Avoiding loud noises (B) is important for overall ear health but does not specifically prevent otitis externa. Instilling antibiotic ointments regularly (C) is not recommended as it can disrupt the ear's natural flora. Avoiding cotton swabs (D) is important to prevent injury but does not directly prevent otitis externa.
