RN HESI Exit Exam

Correct Answer: B

Rationale: Administering insulin is the most important intervention in managing diabetic ketoacidosis. Insulin helps to reduce blood glucose levels and correct metabolic acidosis, which are critical in the treatment of DKA. While administering intravenous fluids is essential to manage dehydration, insulin takes precedence in treating the underlying cause of DKA. Monitoring urine output is important for assessing renal function but is not the primary intervention in managing DKA. Checking the client's blood glucose level is necessary, but administering insulin to reduce high blood glucose levels is the key priority in treating DKA.

Correct Answer: D

Rationale: The correct answer is to notify the healthcare provider immediately (Option D). Blurred vision in a client on long-term steroid therapy can be a sign of serious conditions like cataracts or glaucoma, which need urgent medical evaluation and management. Instructing the client to use artificial tears (Option A) may help with dry eyes but does not address the underlying cause of blurred vision. Administering an ophthalmic antibiotic (Option B) is not indicated unless there is a specific infection present. Referring the client to an optometrist for an eye exam (Option C) may delay necessary medical intervention by the healthcare provider, who should be involved promptly in this situation.

Correct Answer: D

Rationale: The correct answer is to administer 50% dextrose IV push first. In hyperglycemic hyperosmolar syndrome, the main goal is to rapidly reduce blood glucose levels to prevent further complications. Administering dextrose intravenously can help reverse the effects of high blood glucose levels quickly. Administering intravenous fluids, monitoring urine output, and obtaining a blood glucose level are important interventions but are not the first priority in treating HHS. Administering 50% dextrose IV push takes precedence as it directly addresses the elevated blood glucose levels.

Correct Answer: B

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, an elevated blood pressure is the most concerning assessment finding. Elevated blood pressure can indicate worsening hypertension, which requires immediate intervention. Increased fatigue may be expected due to anemia associated with CKD and erythropoietin therapy. Low urine output may indicate impaired kidney function but is not as immediately concerning as elevated blood pressure. Elevated hemoglobin levels are the desired outcome of erythropoietin therapy, indicating an appropriate response to treatment.

Correct Answer: A

Rationale: The correct answer is A: Widening QRS complexes and flat T waves. In the context of an adult male with delirium tremens and symptoms like tachycardia, diaphoresis, restlessness, and disorientation, the presence of widening QRS complexes and flat T waves on an ECG suggests severe electrolyte imbalance, particularly hypokalemia. This severe electrolyte imbalance can lead to life-threatening arrhythmias such as ventricular tachycardia or fibrillation. Tachycardia and elevated blood pressure (choice B) can be expected in delirium tremens but do not directly indicate a life-threatening condition as widening QRS complexes and flat T waves do. Restlessness and anxiety (choice C) are common symptoms of delirium tremens but do not specifically signify a life-threatening condition. Diaphoresis and dehydration (choice D) are also common in delirium tremens but do not directly point towards a life-threatening electrolyte imbalance as widening QRS complexes and flat T waves do.
