Correct Answer: D

Rationale: The most appropriate diagnostic examination to confirm the incidence of hypertension among residents is blood pressure (BP) monitoring. Hypertension is defined by elevated blood pressure readings consistently measured over time. Monitoring of blood pressure is essential for diagnosing hypertension and determining the severity of the condition. Chest x-ray, ultrasound, and electrocardiogram are not specific tests for diagnosing hypertension. While these tests may be useful in assessing potential complications or causes of hypertension, they do not directly confirm the presence of high blood pressure. Regular BP monitoring with the use of a sphygmomanometer or automated blood pressure device is crucial in diagnosing and managing hypertension.

Correct Answer: D

Rationale: The diagnosis of gestational diabetes mellitus (GDM) is typically confirmed through an oral glucose tolerance test (OGTT) during pregnancy. In GDM, the 2-hour plasma glucose level during the OGTT is equal to or greater than 140 mg/dL. This finding is characteristic of GDM and distinguishes it from other types of diabetes. Fasting blood glucose ≥126 mg/dL is diagnostic of diabetes mellitus outside of pregnancy, not specifically GDM. Random plasma glucose ≥200 mg/dL is indicative of uncontrolled diabetes in general. Hemoglobin A1c (HbA1c) ≥6.5% is used for diagnosing diabetes outside of pregnancy and is not specific to GDM.

Correct Answer: C

Rationale: The patient's presentation of thyroid nodule with compression symptoms like difficulty swallowing and breathing, along with fine-needle aspiration biopsy showing a follicular pattern and colloid-filled spaces, is highly suggestive of a follicular adenoma. Follicular adenomas are benign thyroid tumors that can cause compression symptoms due to their growth and size, leading to pressure on surrounding structures in the neck area. The presence of colloid-filled spaces in the biopsy is characteristic of follicular adenomas.

Correct Answer: C

Rationale: Assessing the mental status of the patient is the PRIORITY nursing action to determine the patient's ability to concentrate and focus. This assessment includes evaluating the patient's level of alertness, orientation, memory, thought processes, and mood. By observing the patient's mental status, the nurse can gain valuable information about the patient's cognitive function, attention span, and ability to concentrate. This assessment will help guide further interventions and care planning for the patient. Asking for academic performance or conducting paper and pencil tests may be useful tools to assess concentration and focus, but they should come after a comprehensive evaluation of the patient's mental status. Referring the patient to a psychiatrist may be necessary based on the assessment findings, but it should not be the first step in determining the patient's ability to concentrate and focus.

Correct Answer: B

Rationale: Beta-blockers work by blocking the effects of adrenaline on beta receptors in the body. One common adverse effect of beta-blockers is bradycardia, or a slowed heart rate. Since the patient is being prescribed a beta-blocker for migraine headaches, it is important for the nurse to monitor closely for signs and symptoms of bradycardia such as dizziness, fatigue, and fainting. Monitoring the heart rate regularly and reporting any significant decrease to the healthcare provider is essential to prevent complications associated with bradycardia. Compared to the other options, bradycardia is the most relevant adverse effect to monitor in a patient prescribed a beta-blocker.
