HESI Medical Surgical Exam

Correct Answer: B

Rationale: The correct answer is B: 'Reduce the workload on the kidneys.' A low-protein diet is prescribed for clients with chronic renal failure to decrease the production of urea and other nitrogenous wastes, which can accumulate in the body when the kidneys are not functioning properly. This reduction in protein intake helps to lessen the burden on the kidneys, as they may have difficulty in filtering and excreting waste products. Choice A is incorrect because fluid overload is more related to restrictions in fluid intake rather than protein intake. Choice C is incorrect as a low-protein diet does not directly prevent dehydration. Choice D is incorrect because while electrolyte balance is essential in renal failure, the primary purpose of a low-protein diet is to reduce the workload on the kidneys by limiting the production of waste products.

Correct Answer: D

Rationale: Coldness of the left foot and ankle is the correct clinical manifestation indicating complete arterial obstruction in the lower left leg. Complete arterial obstruction results in reduced blood flow, leading to decreased temperature in the affected area. Aching pain (Choice A) and burning pain (Choice B) are more commonly associated with partial obstructions or ischemia, while numbness and tingling (Choice C) can be indicative of nerve involvement or compromised circulation, but not specifically complete arterial obstruction. The coldness in the foot and ankle is a result of severely reduced blood flow, which impairs the delivery of oxygen and nutrients to the tissues in that area, leading to a lower temperature. This symptom is a critical indicator of a more severe blockage compared to the other options provided.

Correct Answer: D

Rationale: The correct answer is D: Eyes. Diabetic clients are at high risk of developing complications such as diabetic retinopathy, making regular eye examinations crucial. Assessing the eyes helps in early detection and management of diabetic eye diseases. Choices A, B, and C are incorrect because while they may be relevant in certain assessments, they are not commonly associated with complications specific to diabetes. Examination of the abdomen, lymph glands, and pharynx are not typically part of routine assessments for common complications in diabetic clients.

Correct Answer: D

Rationale: The correct answer is D: Disulfiram (Antabuse)-like symptoms. When a client with diabetes mellitus taking a sulfonylurea consumes alcohol, it can lead to disulfiram-like symptoms, such as nausea, flushing, and palpitations. Choice A, hypokalemia, is incorrect because sulfonylureas do not typically lead to low potassium levels. Choice B, hyperkalemia, is incorrect as sulfonylureas are not associated with high potassium levels. Choice C, hypocalcemia, is also incorrect because sulfonylureas are not known to cause low calcium levels.

Correct Answer: A

Rationale: The correct first nursing action when a client reports chest heaviness post-hip surgery is to gather more information through assessment. Inquiring about the onset, duration, severity, and precipitating factors of the heaviness is crucial to determine the cause. This approach helps the nurse to gather essential data to make an informed decision regarding the client's care. Administering oxygen (Choice B) may be indicated based on assessment findings, but it is crucial to assess first. Offering pain medication (Choice C) without further assessment is premature and may mask symptoms. Informing the physician (Choice D) should be done after a thorough assessment to provide comprehensive information for appropriate medical decision-making.
