The nurse is preparing an older adult client for a magnetic resonance imaging (MRI) with contrast. Which laboratory value should the nurse report to the healthcare provider before the scan is performed?
Reference Range:
Glycosylated Hemoglobin (4% to 5.9% ]
Creatinine 10.6 to 1.2 mg/dL (53 to 106 μmol/L)]
Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)]
Blood Urea Nitrogen [10 to 20 mg/dL (3.6 to 7.1 mmol/L)]
Fasting blood sugar of 200 mg/dl. (11.1 mmol/L).
Serum creatinine of 1.9 mg/dl. (168 μmol/l)
Glycosylated hemoglobin of 8%.
Blood urea nitrogen of 22 mg/dL (7.9 mmol/L)
The Correct Answer is B
B. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys. Elevated serum creatinine levels may indicate impaired kidney function. Since contrast agents can affect renal function, a serum creatinine level above the reference range should be reported to the healthcare provider before the MRI with contrast.
A. While elevated blood sugar levels may indicate diabetes or poor glycemic control, they are not directly related to kidney function or the risk of contrast-induced nephropathy. Therefore, this value is not the most pertinent for reporting before an MRI with contrast.
C. Glycosylated hemoglobin (HbA1c) reflects average blood glucose levels over the past two to three months and is used to assess long-term glycemic control in diabetes. While elevated HbA1c levels suggest poor diabetes management, they do not directly assess kidney function or the risk of contrast-induced nephropathy.
D. Blood urea nitrogen (BUN) levels reflect the amount of urea nitrogen in the blood and can indicate kidney function. Elevated BUN levels may suggest impaired renal function. However, an elevated serum creatinine is a more reliable marker for renal excretion.

Correct Answer is B
Explanation
B. Acute pancreatitis is inflammation of the pancreas that can cause severe upper abdominal pain, which may radiate to the back, fever, and vomiting. Elevated serum amylase and lipase levels are characteristic laboratory findings in acute pancreatitis, indicating pancreatic injury or inflammation. The client's symptoms and laboratory results are consistent with acute pancreatitis.
A. Hepatorenal failure, also known as hepatorenal syndrome, is a serious complication of advanced liver disease where there is progressive renal failure in the setting of liver dysfunction. While hepatorenal syndrome can present with symptoms such as abdominal pain, fever, and vomiting, it is not typically associated with significantly elevated serum amylase and lipase levels.
C. Biliary duct obstruction occurs when there is a blockage in the bile ducts, leading to impaired flow of bile from the liver to the small intestine. While biliary duct obstruction can cause symptoms such as upper abdominal pain and vomiting, it is not typically associated with significantly elevated serum amylase and lipase levels.
D. While surgical site infection is a potential complication following cholecystectomy (gallbladder removal surgery), it typically presents with symptoms such as wound redness, swelling, warmth, and purulent drainage from the incision site.
Correct Answer is D
Explanation
A. Complete restriction of physical activities is not necessary. The nurse should provide guidance on gradually resuming normal activities based on the healthcare provider's recommendations.
B. Incentive spirometer is not directly related to the management or recovery following TUNA for BPH. This device is typically used to improve lung function and prevent respiratory complications, which may not be a primary concern in this scenario.
C.While clients should monitor hematuria, the primary focus post-TUNA is on urinary output and function rather than just the color of the urine. Changes in hematuria color are important, but they may not directly correlate to urgent issues.
D. After TUNA, clients need to be vigilant about their urinary output because a decrease can indicate complications such as re-obstruction, which is a significant concern following the procedure. Monitoring urinary stream is essential for detecting potential issues early, making this the best choice for discharge instructions.
