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 ["A","C","E"]

Explanation

A. Standard precautions should always be followed when caring for any patient to prevent the transmission of infectious agents. Additionally, wearing a mask can provide further protection, especially if there is a risk of respiratory droplet transmission.
C. Culturing the wound drainage allows for the identification of the specific bacteria causing the infection, including whether it is methicillin-resistant Staphylococcus aureus (MRSA). Sensitivity testing helps determine which antibiotics are effective against the bacteria, guiding appropriate antibiotic therapy.
E. Contact precautions are necessary for preventing the transmission of MRSA to other patients, staff, and visitors. This includes wearing gloves and gowns when providing care, as well as ensuring proper hand hygiene practices. Visitors may also need to follow specific precautions to prevent the spread of infection.
B. While monitoring the client's white blood cell count may be important for assessing the body's response to infection, it is not specific to MRSA infection. MRSA infection is typically diagnosed based on clinical presentation and confirmed through laboratory tests such as wound cultures.
D. A low bacteria diet is not typically indicated for MRSA infection. MRSA is primarily treated with antibiotics, and dietary modifications are not a standard part of its management.

A. Cold hands and feet. B. Myalgia in wrists and hands. C. Excessive perspiration. D. Dark yellow urine.

Correct Answer is C

Explanation

C. The client's symptoms of weakness and palpitations are suggestive of hypoglycemia, a common complication in individuals with diabetes, particularly those on glucose-lowering medications such as insulin or sulfonylureas. Excessive perspiration, also known as diaphoresis, is a classic symptom of hypoglycemia and indicates the body's response to low blood sugar levels.

A. Cold extremities can be a sign of poor peripheral circulation, which may occur in individuals with diabetes, particularly in advanced stages or in the presence of peripheral vascular disease. However, it is not as specific to the acute episode of hypoglycemia
B. Myalgia (muscle pain) in the wrists and hands is not a typical symptom of hypoglycemia.
D. Dark yellow urine may indicate dehydration, which can occur in individuals with poorly controlled diabetes or during episodes of hyperglycemia. While dehydration is a concern in diabetes management, it is not directly related to the acute episode of hypoglycemia.
