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 A
Explanation
Choice A reason:
Injecting air into the short-acting insulin vial is the first action to be taken. When mixing short-acting and intermediate-acting insulins in the same syringe, the first step is to inject air into the short-acting insulin (clear) vial. This helps equalize the pressure within the vial, making it easier to withdraw the correct dose of insulin
Choice B reason:
Drawing up the desired dose of intermediate-acting insulin into the same syringe is incorrect because it is the last step to be taken.
Choice C reason:
Drawing up the desired dose of short-acting insulin into the syringe is incorrect because it is the third step to be taken.
Choice D reason:
Inject air into the intermediate-acting insulin (cloudy) vial is incorrect because it is the second step to be taken
Correct Answer is D
Explanation
A. Hyperextend the client's back while the fracture pan is in place: Hyperextending the client's back is not necessary and can cause discomfort or strain. The client's back should be kept in a neutral position.
B. Keep the bed flat while the client is on the fracture pan: Raising the head of the bed slightly can facilitate the client's positioning and defecation. It is not necessary to keep the bed completely flat.
C. Encourage the client to try to defecate for 20 minutes while on the fracture pan: Encouraging the client to try to defecate for a specific time frame is not necessary and may lead to discomfort or straining. The client should be allowed to take the time they need and not be rushed during this process.
D. Place the shallow end of the fracture pan under the client's buttocks: When using a fracture bedpan, the shallow end should be placed under the client's buttocks to allow for proper positioning. The higher, deeper end of the bedpan is positioned under the client's lower back.
