Final answer:
The nurse should expect the troponin I values to be elevated in the laboratory values of a client who had a MI 3 hours ago.
Step-by-step explanation:
The nurse should expect the troponin I values to be elevated in the laboratory values of a client who had a MI (myocardial infarction) 3 hours earlier. Troponin I is a cardiac marker that is released into the bloodstream when there is damage to the heart muscle, such as during an MI.
Other laboratory values that may be elevated in a client with a recent MI include creatine kinase MB (CK-MB), another cardiac enzyme, and LDH (lactate dehydrogenase). However, the question specifically asks for the value that would be elevated, so the correct answer is troponin I.
It is important for the nurse to monitor these laboratory values to assess the extent of the heart damage and guide further treatment decisions.
