, A patient is admitted with chest pain to the ER. The patient has been in the
ER for 5 hours and is being admitted to your unit for overnight
observation. From the options below, what is the most IMPORTANT
information to know about this patient at this time?
a) Troponin result and when the next troponin level is due to be collected
b) Diet status
c) Last consumption of caffeine
d) CK result and when the next CK level is due to be collect
a) Troponin result and when the next troponin level is due to be collected
- The answer is A. The key words in this question are "chest pain" and "been in
the ER for 5 hours". The patient should have already had one troponin level
drawn since it starts to elevate 2-4 hours after injury and has been in the ER for
5 hours. Therefore, it is essential you know what the level is and when the next
level is due. If the patient's chest pain is caused by a myocardial event the
troponin levels will trend upward. Troponin levels are usually ordered every 6
hours x 3. CK results are not as specific as a troponin levels. This question
wanted to know the MOST important, and the troponin level for this
patient/when it is drawn next is MOST important. Diet status and last
consumption of caffeine are things the nurse needs to know but not the MOST
important.

chest pain. You know that _____________ levels elevate 2-4 hours after
injury to the heart and is the most regarded marker by providers.
