Answer to Question 1

D
Any change from baseline is expressed in millimeters and may indicate myocardial ischemia (one small box equals 1 mm). ST segment elevation of 1 to 2 mm is associated with acute myocardial injury, preinfarction, and pericarditis. ST segment depression (decrease from baseline more of 1 to 2 mm) is associated with myocardial ischemia. Widened QRS complexes are indicative of ventricular depolarization abnormalities such as bundle branch blocks and ventricular dysrhythmias. Q waves and smaller R waves are indications usually present 24 hours to 1 week after the myocardial infarction is completely evolved; they represent necrosis.

Answer to Question 2

D
A history of recent onset of nausea and vomiting or appetite loss caused by taste changes (uremia often causes a metallic taste) may provide clues to the rapid onset of kidney problems. Glycosuria is the presence of glucose in the urine. Proteinuria is the presence of protein in the urine. Myoglobin is the presence of red blood cells in the urine.
