A patient is in the ER for a suspected myocardial infarction.
The nurse sends a blood sample to the lab.
The patient asked the nurse what laboratory levels would be elevated to indicate an MI. The nurse replies:
Elevated potassium levels.
Elevated CK-MB and Troponin levels.
Elevated Lipid profile.
Elevated WBC count.
The Correct Answer is B
Choice A rationale:
Elevated potassium levels are not a specific indicator of a myocardial infarction (MI). They could be due to other conditions like kidney disease.
Choice B rationale:
Elevated CK-MB and Troponin levels are indeed indicators of an MI. These proteins are released into the blood when heart muscle is damaged.
Choice C rationale:
An elevated lipid profile is a risk factor for heart disease, but it does not indicate an acute MI.
Choice D rationale:
An elevated WBC count could indicate an infection or inflammation, but it is not a specific indicator of an MI.

Correct Answer is ["1140"]
Explanation
To calculate the total intake, we need to convert all measurements to mL. 1 oz is approximately 30 mL, 1 cup is approximately 240 mL. So, 4 oz of soda is 120 mL, 12 oz of water is 360 mL, 1 cup of gelatin is 240 mL, and 1/2 cup of broth is 120 mL. Adding these to the 300 mL of IV fluid gives us 1140 mL. However, the toast is not a liquid and cannot be measured in mL, so it is not included in the total intake.
