Adult Health Nursing First Chapter Quizlet

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: D

Rationale: If a nurse notices a discrepancy between the surgical count and the number of instruments on the sterile field during surgery, it is crucial to inform the surgical team immediately and initiate a thorough search. Patient safety is of utmost importance, and any missing instruments could potentially pose a risk to the patient. By informing the team and conducting a thorough search, the missing instrument can be located promptly to ensure it is not inadvertently left inside the patient's body. Continuing with the procedure or ignoring the discrepancy without further investigation could lead to serious consequences for the patient's well-being. It is always better to address any discrepancies or concerns during surgery proactively to maintain a high standard of patient care and safety.

Correct Answer: B

Rationale: The laboratory test used to monitor the therapeutic effect of warfarin therapy is the International Normalized Ratio (INR). Warfarin is a commonly prescribed anticoagulant medication that works by inhibiting the action of vitamin K-dependent clotting factors. Maintaining the INR within the target range specific to the indication for anticoagulation (e.g., DVT prevention or treatment) is essential to balance the risk of bleeding and clotting.

Correct Answer: B

Rationale: Periodontitis is the dental condition characterized by inflammation of the gingival tissues surrounding the teeth. It is typically caused by poor oral hygiene practices, leading to plaque buildup and eventually gum disease. If left untreated, periodontitis can cause serious damage to the gum tissue and the underlying bones supporting the teeth, which can eventually result in tooth loss. Regular dental check-ups, proper oral hygiene habits, and professional cleanings are important for preventing and managing periodontitis.

Correct Answer: B

Rationale: Opsonization is a process in the immune response where opsonins, which are proteins such as antibodies and complement proteins, bind to pathogens such as bacteria, making them more easily recognized and engulfed by phagocytic cells like macrophages and neutrophils. This coating of pathogens by opsonins enhances the efficiency of phagocytosis, helping in the elimination of pathogens from the body. Opsonins do not facilitate cell lysis, neutralize toxins, or stimulate histamine release; their main function is to tag pathogens for phagocytosis.
