HESI Medical Surgical Practice Exam

Correct Answer: B

Rationale: The correct answer is B: Moon face. Cushing's syndrome is characterized by excess cortisol levels, leading to the distinctive round and full face known as moon face. Hyperpigmentation (choice A) may occur due to increased ACTH levels, but it is not a hallmark symptom like moon face. Hypotension (choice C) is less common in Cushing's syndrome as cortisol typically leads to hypertension (choice D) due to its effects on blood pressure regulation.

Correct Answer: C

Rationale: Cold intolerance is a key symptom of hypothyroidism because a decreased metabolic rate leads to a reduced ability to regulate body temperature. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the metabolic rate is increased. Heat intolerance (Choice B) is also more indicative of hyperthyroidism, where excess thyroid hormone leads to an increased sensitivity to heat. Increased appetite (Choice D) is not typically seen in hypothyroidism; instead, individuals with hypothyroidism may experience weight gain due to the slowed metabolism.

Correct Answer: D

Rationale: Alteplase recombinant, or t-PA, is a thrombolytic enzyme used to dissolve clots and revascularize the blocked coronary artery in patients experiencing a myocardial infarction (MI). Administering t-PA within the first 6 hours of MI onset is crucial to restore blood flow to the affected area and minimize cardiac tissue damage. Therefore, the correct answer is to revascularize the blocked coronary artery. Choices A, B, and C are incorrect because while controlling chest pain, reducing coronary artery vasospasm, and managing arrhythmias are important goals in managing MI, the primary purpose of administering t-PA within the first 6 hours is to restore blood flow by dissolving clots and revascularizing the blocked coronary artery.

Correct Answer: C

Rationale: Obesity is the most significant risk factor for developing type 2 diabetes mellitus due to its role in insulin resistance. Excess body fat, especially around the abdomen, leads to increased production of inflammatory markers and hormones that can cause insulin resistance. While cigarette smoking, high-cholesterol diet, and hypertension can contribute to health issues, they are not as directly linked to the development of type 2 diabetes mellitus as obesity.

Correct Answer: B

Rationale: The correct answer is monitoring the patient's respiratory rate. When a patient receives intravenous morphine, the priority assessment is to monitor the respiratory rate due to the risk of respiratory depression associated with morphine. This assessment helps in detecting and managing any potential respiratory complications promptly. Assessing blood pressure, checking pain level, and monitoring oxygen saturation are important aspects of patient care but are not the priority when considering the specific risk of respiratory depression with intravenous morphine.
