A nurse is caring for a client who is scheduled to have his alanine aminotransferase (ALT) level checked. The client asks the nurse to explain the laboratory test. Which of the following is an appropriate response by the nurse?
"This test is used to check how your kidneys are working."
"This test will indicate if you are at risk for developing blood clots."
"This test will provide information about the function of your liver."
"This test will determine if your heart is performing properly."
The Correct Answer is C
Choice A reason:
ALT is not primarily used to check kidney function. Kidney function is typically assessed through other tests, such as blood urea nitrogen (BUN) and creatinine levels.
Choice B reason:
ALT is not used to assess the risk of blood clots. It is specifically related to liver function.
Choice C reason:
Alanine aminotransferase (ALT) is an enzyme found primarily in the liver. An elevated ALT level in the blood can indicate potential liver damage or disease, so the ALT test is used to assess the function of the liver.
Choice D reason:
ALT is not a test to determine heart performance. Heart function is evaluated using tests such as electrocardiograms (ECGs) or cardiac enzymes.

Correct Answer is B
Explanation
Choice A reason:
Evaluating the healing of an incision is not necessary because it involves clinical judgment and assessment skills, which are generally beyond the scope of practice for assistive personnel.
Choice B reason:
Changing IV tubing is a task that can often be safely delegated to an assistive personnel (AP) who has been trained and deemed competent to perform this task. It is within the AP's scope of practice and doesn't require clinical judgment or assessment.
Choice C reason:
Performing a simple dressing change involves direct contact with a wound and requires knowledge of aseptic technique and wound care principles. This task is typically performed by licensed nursing personnel.
Choice D reason:
Inserting an NG tube is a complex procedure that requires specialized training and skill. It should be performed by a licensed nurse or another healthcare professional with the appropriate training and competence.
Correct Answer is C
Explanation
Choice A reason:
A blood glucose level of 110 mg/dl: A slightly elevated blood glucose level could be expected in response to enteral feeding.
Choice B reason:
Diarrhea one time in a 24-hour period is incorrect. Diarrhea can occur as a side effect of enteral feeding due to changes in the digestive process.
Choice C reason:
An unexpected finding when a client is receiving continuous enteral feeding via an NG tube is a rapid and significant weight gain of 0.91 kg (2 lb) in just 2 days. This could indicate fluid overload, which might be caused by excessive fluid intake or inadequate fluid removal by the body. Rapid weight gain should be assessed and reported as it could be a sign of underlying issues that need to be addressed.
Choice D reason:
A gastric residual of 300 mL at the end of the shift is incorrect. Gastric residuals can fluctuate during continuous enteral feeding, and a residual of 300 mL may not necessarily be unexpected depending on the client's overall condition and the healthcare provider's guidelines.
