A patient expresses distrust in the healthcare system due to previous negative experiences. What is the nurse's best approach to rebuild trust?

Correct Answer: B

Rationale: The correct answer is B because actively listening, acknowledging the patient's concerns, and working towards rebuilding trust through transparency and reliability are essential steps in addressing distrust. By validating the patient's experiences and actively involving them in the process, the nurse can foster a supportive and trusting relationship. Choice A is incorrect because dismissing the patient's concerns can further damage trust and undermine the patient's feelings. Choice C is incorrect as ignoring the distrust can lead to a breakdown in communication and trust. Choice D is incorrect because telling the patient to trust the healthcare system without addressing their concerns is dismissive and unhelpful.

Correct Answer: A

Rationale: The correct answer is A: Hashimoto's thyroiditis. This autoimmune disorder results in chronic inflammation of the thyroid gland, leading to thyroid nodules and hypothyroidism. The colloid-filled spaces seen in the biopsy are characteristic of Hashimoto's. Choice B: Graves' disease is an autoimmune disorder causing hyperthyroidism, not hypothyroidism. Choice C: Diabetes mellitus is a metabolic disorder unrelated to the thyroid. Choice D: Thyroid nodules is a general term and does not explain the presence of colloid-filled spaces.

Correct Answer: D

Rationale: The correct answer is D: Ventricular tachycardia. Ventricular tachycardia is a serious arrhythmia that can lead to palpitations, dizziness, and syncope due to the rapid and abnormal heart rhythm originating in the ventricles. This arrhythmia can be life-threatening if not promptly treated. A: Stable angina is characterized by chest discomfort or pain due to reduced blood flow to the heart muscle, usually during physical exertion or stress. It does not typically present with palpitations, dizziness, or syncope. B: Unstable angina is a more severe form of angina where symptoms occur even at rest. While it can lead to serious complications like heart attack, it does not commonly present with palpitations, dizziness, or syncope. C: Atrial fibrillation is a common arrhythmia originating in the atria, leading to an irregular and often rapid heartbeat. While it can cause palpitations and dizziness,

Correct Answer: A

Rationale: The correct answer is A: Pulmonary embolism. This is the most likely cause of the symptoms based on the presentation of chest pain, dyspnea, hemoptysis, and a mismatched defect on the V/Q scan. A pulmonary embolism occurs when a blood clot travels to the lungs, causing a blockage in the pulmonary artery. This can lead to symptoms like chest pain, shortness of breath, and coughing up blood. The V/Q scan showing a mismatched defect indicates a ventilation-perfusion mismatch, which is a classic finding in pulmonary embolism. Pericarditis (B), acute myocardial infarction (C), and aortic dissection (D) typically present with different sets of symptoms and do not match the V/Q scan findings in this case.

Correct Answer: C

Rationale: The correct answer is C because providing emotional support and offering counseling or therapy sessions address the root cause of the patient's depression in a holistic manner. This intervention allows the patient to express their emotions, process their feelings, and receive guidance on coping strategies. Encouraging social activities (A) may not directly address the underlying emotional issues. Referring to a psychiatrist for medication (B) should be considered if counseling alone is insufficient. Exploring spiritual beliefs (D) is important but may not be the most immediate priority for addressing depression in this context.
