Removal of part of the liver leads to the remaining liver cells undergoing
compensatory ANS✔✔ Compensatory hyperplasia is an adaptive mechanism
that enables certain organs to regenerate. For example, the removal of part
of the liver leads to hyperplasia of the remaining liver cells (hepatocytes) to
compensate for the loss.
Which of the following statements best describes Raynaud disease?
a. An inflammatory disorder of small and medium-size arteries in the feet
and sometimes in the hands
b. A neoplastic disorder of the lining of the arteries and veins of the upper
extremities
c. A vasospastic disorder of the small arteries and arterioles of the fingers,
and less commonly, the toes
d. An autoimmune disorder of the large arteries and veins of the upper and
lower extremities ANS✔✔ c. A vasospastic disorder of the small arteries and
arterioles of the fingers, and less commonly, the toes
A patient is diagnosed with pulmonary disease and elevated pulmonary
vascular resistance. Which of the following heart failures may result from
this condition?
a. Right heart failure
b. Left heart failure
c. Low-output failure

d. High-output failure ANS✔✔ a. Right heart failure
Exp: Right heart failure is defined as the inability of the right ventricle to
provide adequate blood flow into the pulmonary circulation at a normal
central venous pressure. It most often results from the left heart failure
when the increase in left ventricular filling pressure that is reflected back
into the pulmonary circulation is severe enough. As pressure in the
pulmonary circulation rises, the resistance to right ventricular emptying
increases.
What physical sign is the result of turbulent blood flow through a vessel?
a. Increased blood pressure during periods of stress
b. Bounding pulse felt on palpation
c. Cyanosis observed on excretion
d. Murmur heard on auscultation ANS✔✔ d. Murmur heard on auscultation
Exp: Where flow is obstructed the vessel turns or blood flows over rough
surfaces. The flow becomes turbulent with whorls or eddy currents that
produce noise causing a murmur to be heard on auscultation such as occurs
during blood pressure measurement with a sphygomanometer. This
selection is the only option that accurately identifies the physical sign of
turbulent vascular blood flow. pg 1113
Which congenital heart defects occur in trisomy 13, trisomy 18 and down
syndrome?
a. Coarctation of the aorta and pulmonary stenosis
b. Tetralogy of Fallot and persistent truncus arteriosus
c. Atrial septal defect and dextrocardia
d. Ventricular septal defect and patent ductus arteriosus ANS✔✔ d.
Ventricular septal defect and patent ductus arteriosus
, Solution 2024/2025
Pepper
Exp: Congenital heart defects that are related to dysfunction of trisomy 13,
trisomy 18 and down syndrome include VSD and PDA see Table 33-2 The
other defects are not associated with dysfunction of trisomy 13 or 17 and
down syndrome. pg 1200
An infant has a continuous machine/type murmur best heard at the left
upper sternal border throughout systole and diastole as well as a bounding
pulse and a thrill on palpation. These clinical findings are consistent with
which congenital heart defect?
a. Atrial septal defect
b. Ventricular septal defect
c. Patent ductus arteriosus
d. Atrioventricular canal defect ANS✔✔ c. Patent ductus arteriosus
Exp: If pulmonary vascular resistance has fallen then infants with will
characteristically have a continuous machine/type murmur best heard at
the left upper sternal border throughout systole and diastole. If the PDA is
significant then the infant also will have bounding pulses an active
precordium, a thrill on palpation and signs and symptoms of pulmonary over
circulation. The presentations of the other congenital heart defects are not
consistent with the described the symptoms pages 1203-1204
Which compensatory mechanism is spontaneously used by children
diagnosed with tetralogy of Fallot to relieve hypoxic spells?
a. Lying on their left side
b. Performing the valsalva maneuver
c. Squatting
d. hyperventilating ANS✔✔ c. Squatting
Exp: squatting is a spontaneous compensatory mechanism used by older
children to alleviate hypoxic spells. Squatting and its variants increase

systemic resistance while decreasing venous return to the heart from the
inferior vena cava. The other options would not result in these changes. pg
1209
An infant diagnosed with a small patent ductus arteriosus would likely
exhibit which symptom?
a. Intermittent murmur
b. Lack of symptoms
c. Need for surgical repair
d. Triad of congenital defects ANS✔✔ b. Lack of symptoms
Exp: Infants with a small PDA usually remain asymptomatic. page 1203-
1204
Fluid in the pleural space characterizes which condition?
a. Pleural effusion
b. Atelectasis
c. Bronchiectasis
d. Ischemia ANS✔✔ a. Pleural Effusion
Exp: Pleural effusion is the presence of fluid in the pleural space. page1254
Which medication classification is generally included in the treatment of
silicosis?
a. Corticosteroids
b. Antiboitics
c. Bronchodilators
