HESI Medical Surgical Practice Exam

Correct Answer: B

Rationale: Monitoring for signs of infection is crucial in clients receiving hemodialysis because they are at an increased risk of infection due to the invasive nature of the procedure. Administering anticoagulants is not typically a part of the routine care for clients undergoing hemodialysis unless specifically prescribed. While a high-protein diet may be beneficial for some clients, it is not a specific intervention related to hemodialysis. Encouraging fluid intake must be individualized based on the client's fluid status and should not be a generalized recommendation for all clients receiving hemodialysis.

Correct Answer: D

Rationale: In this scenario, the client is presenting with signs of sepsis, such as hypotension, hypothermia, and a recent history of partial-thickness burns with open wounds. The development of watery diarrhea further raises suspicion for sepsis. With a blood pressure of 82/40 mmHg and a low temperature of 96�F (36.6�C), the nurse should recognize the potential for septic shock. Notifying the rapid response team is crucial in this situation as the client requires immediate intervention and management to prevent deterioration and address the underlying septic process. Increasing the room temperature (Choice A) is not the priority as the low body temperature is likely due to systemic vasodilation and not environmental factors. While assessing oxygen saturation (Choice B) is important, the client's hypotension and hypothermia take precedence. Continuing to monitor vital signs (Choice C) alone is insufficient given the critical condition of the client and the need for prompt action to address the sepsis and potential septic shock.

Correct Answer: C

Rationale: The serum potassium level should be monitored closely in clients undergoing hemodialysis due to the risk of hyperkalemia. Hemodialysis is used to remove waste products and excess electrolytes like potassium from the blood. Monitoring potassium levels is crucial because an imbalance can lead to serious cardiac complications, making it the priority value to monitor in this scenario. Monitoring hemoglobin levels (choice A) is important for anemia assessment in chronic renal failure but is not directly related to hemodialysis. Blood urea nitrogen (BUN) levels (choice B) and creatinine levels (choice D) are commonly monitored in renal function tests but are not the top priority for monitoring in a client undergoing hemodialysis.

Correct Answer: D

Rationale: The correct answer is to prepare the client for emergency surgery. The client's presentation with bright red blood in vomitus suggests active bleeding, which is a medical emergency. With a hemoglobin of 12 g/dL and a hematocrit of 35%, the client is likely experiencing significant blood loss that may require surgical intervention to address the source of bleeding. Continuing to monitor for blood loss (Choice A) is not appropriate in this acute situation where immediate action is necessary. Administering normal saline (Choice B) may help with fluid resuscitation but does not address the underlying cause of bleeding. Transfusing platelets (Choice C) is not indicated in this scenario as platelets are involved in clot formation and are not the primary treatment for active bleeding in this context.

Correct Answer: B

Rationale: Age is a nonmodifiable risk factor for atherosclerosis because it is a natural part of the aging process. While lifestyle factors such as diabetes, exercise level, and dietary preferences can be modified to reduce the risk of atherosclerosis, age cannot be altered. Therefore, age is the correct answer. Diabetes, exercise level, and dietary preferences can all be improved or managed through interventions and lifestyle changes to mitigate the risk of atherosclerosis.
