Correct Answer: A

Rationale: Hashimoto's thyroiditis is an autoimmune disorder characterized by chronic inflammation of the thyroid gland. In this condition, lymphocytic infiltration and germinal centers can be seen in the thyroid tissue. This inflammation can lead to the formation of thyroid nodules and enlargement of the thyroid gland, causing symptoms such as difficulty swallowing and breathing due to compression of surrounding structures. Additionally, Hashimoto's thyroiditis can result in hypothyroidism over time, further contributing to the symptoms. Therefore, the patient in this case is most likely experiencing these symptoms due to Hashimoto's thyroiditis. Graves' disease, on the other hand, typically presents with hyperthyroidism and is less likely to manifest as compressive symptoms of the thyroid gland.

Correct Answer: C

Rationale: The primary goal of collaboration is to accomplish shared goals and objectives. When individuals work together towards a common purpose, they can combine their different skills, perspectives, and resources to achieve outcomes that could not be accomplished by working alone. Collaborating enables team members to leverage each other's strengths and expertise, leading to more innovative and effective solutions. While camaraderie and efficiency are important aspects of collaboration, the ultimate aim is to successfully achieve the desired goals.

Correct Answer: D

Rationale: Confusion is a potential adverse effect of digoxin therapy. Digoxin toxicity can manifest as various central nervous system symptoms, including confusion, delirium, and disorientation. It is important to monitor for signs of digoxin toxicity in patients taking this medication, especially those with a history of heart failure or renal impairment. Other common signs of digoxin toxicity may include visual disturbances (like halos around lights), gastrointestinal symptoms (like nausea and vomiting), and cardiac arrhythmias. Monitoring serum digoxin levels can help guide therapy and identify toxicity early.

Correct Answer: D

Rationale: The most appropriate question to ask during the assessment of a newly admitted Person Who Uses Drugs (PWUDs) like Korino is to ask about the amount of drug used, its effects, and how long he has been using. This question provides valuable information for treatment planning and understanding the extent of Korino's drug use. By asking about the specific details of his drug use, the nurse can assess the severity of the addiction, potential health risks, and the duration of substance abuse. This information is crucial for developing an individualized treatment plan and providing appropriate care for Korino's needs. Asking open-ended questions about drug use also helps build rapport and trust between the nurse and the patient, which is essential for effective treatment.

Correct Answer: B

Rationale: Gingivitis is a dental condition characterized by inflammation and bleeding of the gingival tissues. It is often caused by poor oral hygiene leading to the accumulation of bacterial plaque along the gumline. The plaque contains bacteria that release toxins, leading to inflammation of the gums. If left untreated, gingivitis can progress to periodontitis, a more serious condition that affects the supporting structures of the teeth. Regular dental cleanings, proper oral hygiene practices, and professional treatment can help manage and prevent gingivitis.
