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)

Answer and Explanation

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. Lactulose works by acidifying the colonic contents, which promotes the conversion of ammonia (NH3) to ammonium (NH4+). Ammonium is less readily absorbed from the colon into the bloodstream, reducing systemic ammonia levels. This action helps alleviate the neurotoxic effects of ammonia on the brain, thereby improving neurological symptoms associated with hepatic encephalopathy.
A. Lactulose is required in clients with hepatic encephalopathy to excrete ammonia lowering its levels in blood. Holding the lactulose dose is inappropriate as the client’s ammonia levels are still high
C. Rehydrating the clients to replace lost fluids in the loose stools is important but does not address
the client’s elevated ammonia levels which may be exacerbating the client’s encephalopathy.
D. Reporting the number of diarrhea stools to the healthcare provider is important for ongoing assessment and management of the client's condition. However, it does not address the clients high ammonia levels.

A. Replace transdermal analgesic patches every 72 hours. B. Administer analgesics on a fixed and continuous schedule. C. Monitor client for break through pain. D. Frequently evaluate the client's pain.

Correct Answer is C

Explanation

C. Breakthrough pain is a transient exacerbation of pain that occurs despite the use of around- the-clock analgesics for persistent pain. Breakthrough pain episodes require rapid intervention with additional analgesics or adjustments to the current pain management regimen to provide adequate pain relief and improve the client's quality of life.
A. Replacing transdermal analgesic patches every 72 hours is important for ensuring consistent delivery of medication, but it is not directly related to addressing breakthrough pain.
B. Administering analgesics on a fixed and continuous schedule is important for maintaining baseline pain control, but it may not address breakthrough pain adequately.
D. Frequently evaluating the client's pain is essential, but monitoring specifically for breakthrough pain ensures timely intervention when pain exacerbations occur.
