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
Hyperkalemia
Hypokalemia
Two clinical signs of hypocalcemia are the Chvostek sign and Trousseau sign. These
clinical signs are not indicative of any of the other options.
Question 6
pts
How does chest wall compliance in an infant differ from that of an adult?
An adult’s chest wall compliance is the same as an infant’s.
An adult’s chest wall compliance is dissimilar to that of an infant’s.
An adult’s chest wall compliance is lower than an infant’s.
An adult’s chest wall compliance is higher than an infant’s.
Chest wall compliance is higher in infants than it is in adults, particularly in premature
infants.

Question 7
pts
What is the most commonly reported symptom of cancer treatment?
Hair loss
Nausea
Weight loss
Fatigue
Fatigue is the most frequently reported symptom of cancer and cancer treatment.
Although patients report the other options, they are not as frequently experienced as
fatigue.
