HESI Medical Surgical Exam

Correct Answer: C

Rationale: The correct answer is 'Cold intolerance.' Hypothyroidism is associated with a decreased metabolic rate, leading to a decreased ability to regulate body temperature and a feeling of being cold. Fatigue (Choice A) and weight gain (Choice B) are also common symptoms of hypothyroidism due to the overall slowing down of bodily functions. Heat intolerance (Choice D) is more commonly associated with hyperthyroidism, where the body's metabolism is overactive, leading to increased heat production.

Correct Answer: D

Rationale: The primary purpose of administering IV fluids to a patient in septic shock is to maintain adequate tissue perfusion. In septic shock, there is a significant drop in blood pressure and systemic vascular resistance leading to poor tissue perfusion. IV fluids help to restore intravascular volume, improve perfusion to vital organs, and prevent organ failure. Choice A ('To reduce blood pressure') is incorrect because IV fluids in septic shock aim to restore tissue perfusion rather than lower blood pressure. Choice B ('To increase cardiac output') is incorrect as the primary goal is to improve tissue perfusion, not specifically increase cardiac output. Choice C ('To stabilize blood glucose levels') is unrelated to the primary purpose of administering IV fluids in septic shock, which is to address the compromised tissue perfusion.

Correct Answer: B

Rationale: The correct answer is 'B: Hypotension.' Hypotension is a common complication of hemodialysis because fluid removal during the process can lead to a drop in blood pressure. The nurse should closely monitor the client for signs of hypotension such as dizziness, lightheadedness, or a decrease in blood pressure readings. Choice 'A: Hyperkalemia' is incorrect because hemodialysis actually helps lower potassium levels by removing excess potassium from the blood. Choice 'C: Infection' is incorrect as it is not a direct complication of hemodialysis but rather a risk associated with invasive procedures. Choice 'D: Fever' is incorrect as fever is not a typical immediate post-hemodialysis complication unless an underlying infection is present.

Correct Answer: C

Rationale: The correct answer is C. Weakness, dizziness, and headache are common adverse effects of Plavix and should be reported. It is essential to consult a physician before stopping Plavix as it plays a crucial role in preventing platelets from sticking together and forming clots. Choices A, B, and D are incorrect. Choice A is a common side effect of Plavix and does not indicate a need for further teaching. Choice B is incorrect because taking Plavix with or without food can affect its absorption and effectiveness. Choice D correctly explains the purpose of prescribing Plavix to prevent clot formation.

Correct Answer: B

Rationale: The correct answer is B: History of cerebral hemorrhage. A history of cerebral hemorrhage is a contraindication to t-PA administration because of the increased risk of bleeding. Choices A, C, and D are incorrect. Age over 60 years is not a contraindication for t-PA administration. While older age may pose some risks, it is not an absolute contraindication. History of heart failure is not a direct contraindication to t-PA administration. Cigarette smoking, while a risk factor for cardiovascular disease, is not a specific contraindication for t-PA administration.
