HESI Medical Surgical Exam

Correct Answer: B

Rationale: Monitoring for signs of infection is crucial in clients undergoing peritoneal dialysis. Peritonitis is a severe complication associated with peritoneal dialysis, making it essential to promptly identify any signs of infection, such as abdominal pain, cloudy dialysate, fever, and an elevated white blood cell count. Administering antibiotics without proper assessment can lead to antibiotic resistance and should not be the initial action. Encouraging increased fluid intake may not be appropriate without assessing the client's fluid status. Monitoring weight alone does not address the immediate risk of peritonitis in a client undergoing peritoneal dialysis.

Correct Answer: A

Rationale: Eating a bedtime snack is the most appropriate intervention to prevent hypoglycemia during the night when NPH insulin peaks. This snack helps maintain blood glucose levels and counteracts the risk of hypoglycemia. Avoiding physical activity is not recommended as it can further lower blood sugar levels. Taking half the usual dose of insulin can lead to inadequate control of blood sugar levels. Discontinuing insulin until the next meal can result in uncontrolled hyperglycemia, especially during the peak action of NPH insulin.

Correct Answer: A

Rationale: The correct infusion rate is 167 mL/hr. This is calculated by dividing the total volume (1000 mL) by the total time (6 hours), resulting in 166.67 mL/hr, which should be rounded to the nearest whole number as 167 mL/hr. This calculation ensures a steady infusion rate over the specified time frame. Choices B, C, and D are incorrect as they do not accurately reflect the correct calculation based on the volume and time provided in the prescription.

Correct Answer: A

Rationale: Elevating the head of the bed to 30 degrees is crucial for a patient with increased intracranial pressure (ICP) because it helps promote venous drainage from the brain, thereby reducing ICP. Keeping the head of the bed elevated helps facilitate cerebral perfusion and can prevent a further increase in ICP. Administering diuretics (Choice B) may be considered in some cases to reduce fluid volume, but it is not the most critical intervention for immediate ICP management. Administering corticosteroids (Choice C) is not typically indicated for managing increased ICP unless there is a specific underlying condition requiring their use. Keeping the patient in a supine position (Choice D) can actually worsen ICP by impeding venous outflow from the brain, making it an incorrect choice for this scenario.

Correct Answer: C

Rationale: The correct answer is 32 units. To determine the correct dose, the nurse needs to add the 10 units of regular insulin to the 22 units of NPH, resulting in a total of 32 units. Therefore, the syringe should read 32 units. Choices A, B, and D are incorrect because they do not reflect the accurate total dose required for the morning insulin administration.
