Question 1
pts
What period follows depolarization of t he myocardium and represents a period during
which no new cardiac potential can b e propagated?
Correct!
Refractory
Threshold
Sinoatrial (SA)
Hyperpolarization
During the refractory period, no n ew cardiac action potential can be initiated by a
stimulus. T his selection is the only option that accurately identifies the per iod described
in the question.
Question 2

121/70 mm Hg
The suggested mean blood press ure for an 8- to 9- year-old child is 106/58 mm Hg. For
a child of 6 to 7 years old, 10 4/55 mm Hg is appropriate; for a 12- to 13-year-old child,
112 /62 mm Hg is appropriate, and for a 16- to 18-y ear-old young man, 121/70 mm Hg is
appropriate.

Yeast
Correct!
Cancer cells
Fungus
Bacteria
Of the options provided, endog enous antigens include only those uniquely produced by
cancerous cells.
