The nurse is caring for a patient who has undergone a mastoidectomy. In an effort to prevent postoperative infection, what intervention should the nurse implement?

Correct Answer: B

Rationale: After a mastoidectomy, the ear should be protected from water for several weeks. This is because exposing the area to water can increase the risk of infection. Keeping the ear dry allows the surgical site to heal properly and reduces the likelihood of postoperative complications such as infection. Therefore, instructing the patient to protect the ear from water is an important intervention to prevent postoperative infection following a mastoidectomy.

Correct Answer: B

Rationale: Smoking cessation most directly addresses the leading cause of cancer deaths in North America, which is lung cancer. Tobacco use, particularly cigarette smoking, is the primary cause of lung cancer. By helping individuals quit smoking, the public health nurse is targeting the main risk factor for lung cancer and therefore addressing the root cause of the issue. This intervention has the potential to have a significant impact on reducing cancer-related deaths in the community. Monthly self-breast exams, annual colonoscopies, and monthly testicular exams are important for detecting breast, colon, and testicular cancers respectively, but they do not directly address the leading cause of cancer deaths in North America.

Correct Answer: D

Rationale: When a patient is experiencing a seizure and begins vomiting, the priority action for the nurse is to turn the patient onto their side. This position helps to prevent aspiration, which can occur when the patient inhales vomit into their lungs. Turning the patient on their side allows for the vomit to drain out of the mouth, reducing the risk of aspiration and maintaining a clear airway. Performing oral suctioning would be necessary after turning the patient on their side, but it is not the initial priority in this situation. Paging the physician and inserting a tongue depressor are not appropriate actions during a seizure and vomiting episode.

Correct Answer: C

Rationale: Megestrol is a synthetic progestational agent that has been found to promote significant weight gain in AIDS patients with wasting syndrome by increasing body fat stores. It is commonly used to stimulate appetite and increase caloric intake in patients experiencing anorexia and weight loss due to various medical conditions, including AIDS-related wasting. Megestrol works by increasing appetite and improving food intake, leading to weight gain and improved nutritional status in patients with HIV/AIDS. It has been shown to be effective in reversing weight loss and improving quality of life in these patients. Therefore, the drug megestrol is the most appropriate choice for promoting weight gain in AIDS patients with wasting syndrome and anorexia.

Correct Answer: D

Rationale: Nucleoside reverse transcriptase inhibitors (NRTIs) are a class of antiretroviral medications typically recommended to be taken without regard to meals. This means that these medications can be taken with or without food. It is important to follow the specific instructions provided by the healthcare provider regarding the timing of medication administration. Taking NRTIs without regard to meals helps ensure consistent absorption of the medication and can help maintain steady drug levels in the body. There are no specific dietary restrictions associated with NRTIs in terms of meal timing or composition.

Correct Answer: C

Rationale: The most appropriate action for a patient with H. pylori is to encourage completion of antibiotic therapy. H. pylori is a bacterium that causes peptic ulcers, and treatment involves a combination of antibiotics to eradicate the infection. Antibiotic therapy is crucial in eliminating the bacteria and preventing complications such as recurrent ulcers or stomach cancer. Therefore, the nurse should prioritize ensuring that the patient completes the prescribed course of antibiotics to effectively treat the H. pylori infection.

Correct Answer: D

Rationale: Black or tarry stools can be caused by certain medications and supplements, such as iron supplements. Since the fecal occult test is negative, it indicates that bleeding is not occurring. Therefore, in this situation, it is important to consider factors that can affect the color of stool, including iron supplementation. Addressing this question can help determine the cause of the black stool and provide appropriate guidance or reassurance to the patient. This response shows a comprehensive understanding of potential causes and demonstrates a thoughtful approach in addressing the patient's concern.

Correct Answer: B

Rationale: Dysuria is defined as a burning or painful sensation during urination. It is a common symptom of various urinary tract infections and other conditions affecting the urinary system. Patients experiencing dysuria often describe a discomfort or burning sensation while passing urine. Therefore, the assessment finding consistent with dysuria is the presence of burning upon urination.

Correct Answer: A

Rationale: Trigeminal neuralgia is a condition characterized by severe facial pain due to irritation or damage to the trigeminal nerve. Factors such as touching or lightly brushing the face, chewing, speaking, or even encountering a breeze can trigger an attack. Therefore, activities like washing the face that involve touching or stimulating the trigeminal nerve can precipitate an attack in patients with trigeminal neuralgia. It is important for patients to be aware of these triggers to help manage and prevent episodes of pain.
