HESI Medical Surgical Exam

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: C

Rationale: Autonomic dysreflexia is a life-threatening condition commonly seen in clients with spinal cord injuries above the T6 level. It is characterized by a sudden onset of excessively high blood pressure due to a noxious stimulus below the level of injury, often a distended bladder. The exaggerated sympathetic response leads to vasoconstriction, resulting in symptoms such as profuse diaphoresis (sweating) and a severe, pounding headache. These symptoms are the body's attempt to lower blood pressure. Complaints of chest pain and shortness of breath (Choice A) are not typical findings in autonomic dysreflexia. Hypotension and venous pooling (Choice B) are opposite manifestations of autonomic dysreflexia, which is characterized by hypertension. Pain and burning sensation upon urination and hematuria (Choice D) are indicative of a urinary tract infection and not specific to autonomic dysreflexia.

Correct Answer: D

Rationale: During the diuretic phase of acute kidney injury (AKI), monitoring for hypovolemia and electrocardiographic (ECG) changes is crucial. Hypovolemia can occur due to the increased urine output in this phase, potentially leading to dehydration and electrolyte imbalances. Electrolyte imbalances can result in ECG changes, such as arrhythmias, which can be life-threatening. Therefore, careful monitoring of fluid status and ECG findings helps in preventing complications. Choices A, B, and C are not the most crucial parameters to monitor during the diuretic phase of AKI. Side effects of total parenteral nutrition (TPN) and Intralipids, uremic irritation of mucous membranes and skin surfaces, and elevated creatinine and blood urea nitrogen (BUN) are important considerations in other phases of AKI or in other conditions, but they are not the primary focus during the diuretic phase when hypovolemia and ECG changes take precedence.

Correct Answer: D

Rationale: Monitoring blood cultures is a crucial intervention in suspected sepsis because it helps identify the causative organism, which is essential for guiding appropriate antibiotic therapy. Administering antibiotics (Choice A) is important but should be guided by blood culture results. Administering IV fluids (Choice B) is also essential to support hemodynamic stability in sepsis. Administering antipyretics (Choice C) may help reduce fever but is not a priority compared to identifying the causative organism through blood cultures.

Correct Answer: D

Rationale: Monitoring blood cultures is a primary intervention for a patient with sepsis because it helps identify the causative organism, which is crucial in guiding appropriate antibiotic therapy. Administering antibiotics (Choice A) is important in treating sepsis but is considered a secondary intervention. Administering IV fluids (Choice B) is also crucial for sepsis management to restore perfusion and hemodynamic stability. Administering antipyretics (Choice C) may help reduce fever, but it is not a primary intervention for managing sepsis.
