The nurse recognizes the need for client education when the client scheduled for a computed tomography (CT) states:

"I will be drinking a lot of fluid after the test is over."

"I will be anesthetized so that I lie perfectly still during the procedure."

"I will make sure I let them know I do not have a shellfish ally."

"will follow the food and drink restrictions as directed before the test is scheduled."

Answer and Explanation

The Correct Answer is B

A.   This statement suggests that the client may not understand the purpose or procedure of the CT scan. CT scans typically do not require the client to drink excessive fluids afterward. However, hydration might be encouraged if contrast dye was used to help eliminate it from the body. Education is needed to clarify post-procedure instructions.
B.   This statement indicates a misconception about the procedure. CT scans do not usually require anesthesia unless it's a complex situation, such as a young child or someone with severe claustrophobia. It's essential to educate the client about what to expect during the CT scan to reduce anxiety and ensure cooperation during the procedure.
C.   This statement shows awareness of potential allergies to contrast dye, which often contains iodine. It indicates that the client understands the importance of disclosing allergies to the healthcare team before the procedure. While this is generally a positive sign of awareness, further education may still be needed to ensure complete understanding of allergy management.
D.   This statement demonstrates understanding of pre-procedure instructions, which often include fasting or specific dietary restrictions. It suggests that the client understands the importance of these restrictions to ensure accurate test results and safety during the CT scan.

Correct Answer is C

Explanation

A. A hematocrit of 40% is within the normal range for females, which is typically around 37-47%. This result is not concerning and does not typically require immediate notification to the surgeon.
B. A creatinine level of 0.9 mg/dL is within the normal range for adults (normal range varies slightly among laboratories but is generally around 0.5-1.1 mg/dL). This result indicates normal kidney function and does not require immediate notification.
C. A white blood cell (WBC) count of 20,000/mm3 is elevated above the normal range, which is typically between 4,500-11,000/mm3. An elevated WBC count could indicate infection or inflammation. Given the client is preoperative, an elevated WBC count may suggest an underlying infection that needs to be addressed before proceeding with surgery. The nurse should notify the surgeon promptly so appropriate evaluation and management can be initiated.
D. A potassium level of 3.8 mEq/L is within the normal range (normal range is generally 3.5-5.0 mEq/L). This result is not concerning and does not require immediate notification to the surgeon.

A. Elevated magnesium level B. Decreased calcium level C. Decreased potassium level D. Elevated sodium level

Correct Answer is C

Explanation

A. Postoperative ileus and significant drainage via an NG tube are more likely to lead to electrolyte losses rather than elevated levels. Elevated magnesium levels are less common and typically associated with conditions such as renal failure or excessive magnesium intake.
B. Calcium levels can be affected by gastrointestinal losses, including drainage via an NG tube. Significant fluid loss can lead to hemoconcentration, potentially causing a relative increase in calcium levels initially. However, prolonged fluid loss can lead to overall depletion of electrolytes, including calcium.
C. When fluids are lost through the NG tube, potassium, which is an intracellular electrolyte, can be lost in large amounts. Prolonged drainage can lead to hypokalemia (decreased potassium levels), which can result in muscle weakness, cardiac dysrhythmias, and other serious complications.
D. Elevated sodium levels (hypernatremia) are more commonly associated with dehydration or excessive sodium intake rather than drainage via an NG tube. In this scenario, sodium levels are less likely to be affected compared to potassium.
