Correct Answer: C

Rationale: The correct action the nurse should take is to apply cold packs to the affected joints in the morning. Rheumatoid arthritis is characterized by inflammation, and applying cold packs can help reduce inflammation and stiffness in the joints. Encouraging the client to avoid physical activity in the morning (Choice A) may worsen stiffness, as movement is beneficial for joint mobility. While NSAIDs (Choice B) can help with pain and inflammation, applying cold packs directly to the affected joints is more targeted and effective. Performing passive range-of-motion exercises (Choice D) can be helpful, but applying cold packs is the priority for reducing inflammation and stiffness.

Correct Answer: B

Rationale: The correct answer is B: 'Serum calcium level of 8.0 mg/dL.' A low serum calcium level indicates hypocalcemia, which is a potential complication of thyroidectomy that can lead to life-threatening consequences, such as tetany or laryngospasm. Therefore, it is crucial for the nurse to report this finding promptly to the provider for timely intervention. Choices A, C, and D are important assessments following a thyroidectomy but are not as critical as detecting and addressing hypocalcemia, which can have serious implications for the client's health.

Correct Answer: A

Rationale: The correct answer is to administer aspirin. Administering aspirin is a priority nursing intervention for a patient experiencing a myocardial infarction because it helps reduce the risk of further clot formation. Aspirin is a common medication given during the early stages of a heart attack to prevent additional clotting. Administering nitroglycerin may also be indicated to help relieve chest pain by dilating blood vessels, but aspirin takes precedence due to its role in preventing clot progression. Administering morphine is not typically the first intervention in myocardial infarction as it can mask symptoms and delay other critical treatments. Surgery is not an immediate priority in the initial management of a myocardial infarction.

Correct Answer: D

Rationale: Spinach is an excellent choice to recommend as it is rich in non-heme iron, which can help improve iron levels in clients with iron deficiency anemia. Eggs (Choice A) are a good source of protein but do not contain as much iron as spinach. Carrots (Choice B) are rich in vitamin A but are not a significant source of iron. White bread (Choice C) is not a good source of iron compared to spinach.

Correct Answer: A

Rationale: The most important nursing assessment for a patient with suspected deep vein thrombosis (DVT) is to check for leg pain. Leg pain is a cardinal symptom of DVT and is often the initial indicator of a blood clot. While assessing for warmth, swelling, and redness are also important in DVT evaluation, leg pain is the most crucial as it can prompt further diagnostic testing and interventions. Performing Homan's sign test is no longer recommended due to its low specificity and potential to dislodge a clot, causing complications. Monitoring for redness is important but may not always be present in DVT cases. Assessing for warmth and swelling is relevant but still secondary to the assessment of leg pain in suspected DVT cases.
