HESI Medical Surgical Exam

Correct Answer: A

Rationale: Weight gain is an expected finding in hypothyroidism due to the decreased metabolic rate. Hypothyroidism leads to a slowing down of bodily functions, including metabolism, which can result in weight gain. Weight loss (Choice B) is more commonly associated with hyperthyroidism where there is an increase in metabolic rate. Increased appetite (Choice C) is also more typical of hyperthyroidism as the body is burning energy at a faster rate. Diarrhea (Choice D) is not a typical symptom of hypothyroidism; instead, constipation is more often observed due to the slowing down of the digestive system.

Correct Answer: C

Rationale: The most important assessment for a patient receiving IV potassium is monitoring blood pressure. IV potassium can cause significant changes in cardiac function, leading to adverse effects such as arrhythmias and cardiac arrest. While respiratory rate, heart rate, and oxygen saturation are important parameters to monitor in clinical practice, blood pressure takes precedence in patients receiving IV potassium due to its direct impact on cardiovascular function. Changes in blood pressure can be an early indicator of potassium-induced cardiac complications, making it crucial to monitor closely during administration.

Correct Answer: B

Rationale: The most important assessment for a client with DVT on heparin therapy is to monitor for signs of bleeding, such as bruising or hematuria. Heparin is an anticoagulant medication that can increase the risk of bleeding. Assessing for bleeding is crucial to prevent complications like hemorrhage. Measuring the circumference of the leg may be relevant for assessing for edema but is not as critical as monitoring for bleeding. Monitoring vital signs and respiratory status are important aspects of care but are not the priority when the client is on heparin therapy for DVT.

Correct Answer: B

Rationale: The correct answer is B: Bananas. Bananas are high in potassium, which should be limited in clients with chronic renal failure to prevent hyperkalemia. Apples (choice A), chicken (choice C), and rice (choice D) are not typically restricted in clients with chronic renal failure. Apples and rice are lower in potassium, while chicken is a good source of lean protein, which is usually encouraged in these clients to meet their protein needs without excess potassium intake.

Correct Answer: C

Rationale: The correct answer is C. Moving the legs helps prevent thrombophlebitis and blood clot formation by promoting venous return in clients on bed rest. This prevents stasis and clot formation in the lower extremities. Choices A, B, and D are incorrect because the primary goal of moving the legs is to prevent thrombophlebitis and blood clot formation, rather than preparing for ambulation, promoting elimination, or decreasing pressure ulcer formation. Ambulation preparation involves different exercises, urinary and intestinal elimination are not directly related to leg movements, and pressure ulcer prevention is more related to repositioning and skin care.
