Question 1
pts
What period follows depolarization of the myocardium and represents a period
during which no new cardiac potential can be propagated?
Refractory
Threshold
Sinoatrial (SA)
Hyperpolarization
During the refractory period, no new cardiac action potential can be initiated
by a stimulus. This selection is the only option that accurately identifies the
period described in the question.
Question 2
pts
What is the suggested mean blood pressure for an 8- to 9-year-old child?
106/58 mm Hg
104/55 mm Hg
,112/62 mm Hg
121/70 mm Hg
The suggested mean blood pressure for an 8- to 9- year-old child is 106/58
mm Hg. For a child of 6 to 7 years old, 104/55 mm Hg is appropriate; for a
12- to 13-year-old child, 112/62 mm Hg is appropriate, and for a 16- to 18-
year-old young man, 121/70 mm Hg is appropriate.
Question 3
pts
Which is an example of an endogenous antigen?
Yeast
Cancer cells
Fungus
Bacteria
Of the options provided, endogenous antigens include only those uniquely
produced by cancerous cells.
Question 4
pts
An infant has a crescendo-decrescendo systolic ejection murmur located
between the second and third intercostal spaces along the left sternal border.
A wide fixed splitting of
, the second heart sound is also found. These clinical findings are consistent with which
congenital heart defect?
Atrioventricular canal (AVC) defect
Patent ductus arteriosus (PDA)
Ventricular septal defect (VSD)
Atrial septal defect (ASD)
Because most children with ASD are asymptomatic, diagnosis is usually
made during a routine physical examination by the auscultation of a
crescendo-decrescendo systolic ejection murmur that reflects increased
blood flow through the pulmonary valve. The location of the murmur is
between the second and third intercostal spaces along the left sternal
border. A wide fixed splitting of the second heart sound is also characteristic
of ASD, reflecting volume overload to the right ventricle and causing
prolonged ejection time and a delay of pulmonic valve closure. The
presentations of other congenital heart defects are not consistent with the
described symptoms.
Question 5
pts
Chvostek and Trousseau signs indicate which electrolyte imbalance?
Hypocalcemia
Hypercalcemia
