RN HESI Exit Exam

Correct Answer: A

Rationale: The correct answer is an Electrocardiogram (ECG). An ECG should be performed first to assess for cardiac ischemia, especially given the client's symptoms and history. Chest X-ray (Choice B) may be ordered to evaluate the lungs but would not be the initial test for this client presenting with chest pain and shortness of breath. Arterial blood gases (ABGs) (Choice C) are used to assess oxygenation and acid-base balance but are not the primary diagnostic test for a client with suspected cardiac issues. Pulmonary function tests (PFTs) (Choice D) are used to assess lung function and would not be the first test indicated in this scenario.

Correct Answer: C

Rationale: A serum creatinine level of 2.5 mg/dl is the most concerning laboratory value in a client with chronic kidney disease scheduled for a renal biopsy. An elevated serum creatinine level indicates impaired kidney function, which is critical information before performing a renal biopsy. Option A (Serum potassium of 5.5 mEq/L) may be concerning for hyperkalemia but is not directly related to the renal biopsy procedure. Option B (Serum creatinine of 1.5 mg/dl) is within normal limits, suggesting relatively normal kidney function. Option D (White blood cell count of 8,000/mm3) is within the normal range and not directly related to the renal biopsy procedure or CKD management.

Correct Answer: D

Rationale: The correct answer is to notify the healthcare provider. Purulent drainage at the incision site is concerning as it may indicate an infection. The healthcare provider needs to be informed promptly to initiate appropriate treatment. Applying a sterile dressing (Choice A) may not address the underlying issue of infection. Reinforcing the dressing and documenting findings (Choice B) is important but should be preceded by notifying the healthcare provider. Removing the dressing and assessing the incision site (Choice C) may disturb the area and should be done under the guidance of the healthcare provider.

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: Heart disease can affect growth, leading to smaller size in children.
