Question 1
2 / 2 pts
Tissue damage caused by the deposition of circulating immune complexes
containing an antibody against the host DNA is the cause of which disease?
Hemolytic anemia
Pernicious anemia
Systemic lupus erythematosus
Myasthenia gravis
Only the deposition of circulating immune complexes containing an antibody
against the host DNA produce tissue damage in individuals with systemic lupus
erythematosus (SLE).
Question 2
2 / 2 pts
How does chest wall compliance in an infant differ from that of an adult?
An adult’s chest wall compliance is lower than an infant’s.
An adult’s chest wall compliance is higher than an infant’s.
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.
Chest wall compliance is higher in infants than it is in adults, particularly in
premature infants.
Question 3
2 / 2 pts

What term is used to describe a hernial protrusion of a saclike cyst that contains
meninges, spinal fluid, and a portion of the spinal cord through a defect in a
posterior arch of a vertebra?
Encephalocele
Meningocele
Spina bifida occulta
Myelomeningocele
Myelomeningocele is a hernial protrusion of a saclike cyst containing meninges,
spinal fluid, and a portion of the spinal cord with its nerves through a defect in the
posterior arch of a vertebra. The remaining options are not appropriate terms to
identity the described condition.
Question 4
2 / 2 pts
Continued therapy of pernicious anemia (PA) generally lasts how long?
6 to 8 weeks
8 to 12 months
Until the iron level is normal
The rest of one’s life
Because PA cannot be cured, maintenance therapy is a life-long endeavor.
Question 5
2 / 2 pts
Cytokines are thought to cause fevers by stimulating the synthesis of which
chemical mediator?

Leukotriene
Histamine
Prostaglandin
Bradykinin
Cytokines seem to raise the thermoregulatory set point through stimulation of
prostaglandin synthesis and turnover in thermoregulatory (brain) and
nonthermoregulatory (peripheral) tissues. The other options do not accurately
identify the appropriate chemical mediator.
Question 6
2 / 2 pts
The World Health Organization (WHO) defines grade 1 (overweight) as a BMI of:
18.5 to 24.9
25 to 29.9
30 to 39.9
40 to 50.9
A BMI of 25 to 29.9 kg/m2 is considered a grade 1 (overweight) classification. A
BMI of 18.5 to 24.9 kg/m2 is considered normal range, whereas 30 to 39.9
kg/m2 is a grade 2 (severe overweight) classification, and a BMI higher than 40
kg/m2 is considered grade 3 (morbidly overweight).
IncorrectQuestion 7
0 / 2 pts
When diagnosed with hemolytic disease of the newborn (HDN), why does the
newborn develop hyperbilirubinemia after birth but not in utero?
Excretion of unconjugated bilirubin through the placenta into the mother’s
circulation is no longer possible.

Hemoglobin does not break down into bilirubin in the intrauterine environment.
The liver of the fetus is too immature to conjugate bilirubin from a lipid-soluble to
water-soluble form.
The destruction of erythrocytes producing bilirubin is greater after birth.
Hyperbilirubinemia occurs in the neonate after birth because excretion of lipid-
soluble unconjugated bilirubin through the placenta is no longer possible. This
selection is the only option that accurately explains why HDN causes
hyperbilirubinemia after birth but not in utero.
Question 8
2 / 2 pts
Which of the following describes how the body compensates for anemia?
Increasing rate and depth of breathing
Decreasing capillary vasoconstriction
Hemoglobin holding more firmly onto oxygen
Kidneys releasing more erythropoietin
Tissue hypoxia creates additional demands and compensatory actions on the
pulmonary and hematologic systems. The rate and depth of breathing increase in
an attempt to increase the availability of oxygen. This selection is the only option
that accurately describes the compensation mechanism in such anemias.
Question 9
2 / 2 pts
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?
Atrial septal defect (ASD)

Ventricular septal defect (VSD)
Patent ductus arteriosus (PDA)
Atrioventricular canal (AVC) defect
If pulmonary vascular resistance has fallen, then infants with PDA 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 overcirculation. The
presentations of the other congenital heart defects are not consistent with the
described the symptoms.
Question 10
2 / 2 pts
Research has shown a link between cancer and which sexually transmitted
disease?
Syphilis
Gonorrhea
Human papillomavirus
Pelvic inflammatory disease
Human papillomavirus (HPV) is the most common sexually transmitted virus in
the United States. High-risk, or oncogenic, HPVs can cause cancer. A
persistence of infection with high-risk HPV is a prerequisite for the development
of cervical intraepithelial neoplasia (CIN) lesions and invasive cervical cancers.
No research supports such a link between the remaining options and cancer.
Question 11
2 / 2 pts
When renin is released, it is capable of which action?
Inactivation of autoregulation

Loading page 6...

Direct activation of angiotensin II
Direct release of antidiuretic hormone (ADH)
Formation of angiotensin I
When renin is released, it cleaves an α-globulin (angiotensinogen produced by
liver hepatocytes) in the plasma to form angiotensin I.
Question 12
2 / 2 pts
What characteristic do atopic individuals have that make them genetically
predisposed to develop allergies?
Greater quantities of histamine
More histamine receptors
Greater quantities of IgE
A deficiency in epinephrine
Atopic individuals tend to produce higher quantities of IgE and to have more
crystalline fragment (Fc) receptors for IgE on their mast cells. The other options
do not cause this reaction.
Question 13
2 / 2 pts
What is the primary cause of the symptoms of polycythemia vera?
Decreased erythrocyte count
Destruction of erythrocytes

Loading page 7...

Increased blood viscosity
Neurologic involvement
As polycythemia vera progresses, many of the symptoms are related to the
increased blood cellularity and viscosity. No other option is the primary cause of
the symptoms of polycythemia vera.
Question 14
2 / 2 pts
Pressure in the left ventricle must exceed pressure in which structure before the
left ventricle can eject blood?
Superior vena cava
Aorta
Inferior vena cava
Pulmonary veins
Pressure in the ventricle must exceed aortic pressure before blood can be
pumped out during systole. The aorta is the only structure in which pressure
must be less than the amount of blood in the left ventricle for ejection to occur.
Question 15
2 / 2 pts
Children with phenylketonuria (PKU) are unable to synthesize:
Essential amino acid, phenylalanine, to tyrosine
Renin, erythropoietin, and antidiuretic hormone
Aldosterone, cortisol, and androgens

Loading page 8...

Neurotransmitters gamma-aminobutyric acid (GABA) and acetylcholine
PKU is an inborn error of metabolism characterized by the inability of the body to
convert the essential amino acid, phenylalanine, to tyrosine. PKU does not affect
synthesis of the other options.
Question 16
2 / 2 pts
What is the chance with each pregnancy that a child born to two parents with the
sickle trait will have sickle cell disease (SCD)?
20%
25%
33%
50%
A 25% chance exists with each pregnancy that a child born to two parents with
sickle cell trait will have SCD. Genetic counseling enables people with SCD or
with the sickle cell trait to make informed decisions about transmitting this genetic
disorder to their offspring.
Question 17
2 / 2 pts
Carcinoma refers to abnormal cell proliferation originating from which tissue
origin?
Blood vessels
Epithelial cells
Connective tissue
Glandular tissue

Loading page 9...

Only cancers arising from epithelial cells are called carcinomas.
Question 18
2 / 2 pts
Chvostek and Trousseau signs indicate which electrolyte imbalance?
Hypokalemia
Hyperkalemia
Hypocalcemia
Hypercalcemia
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 19
2 / 2 pts
The ability of the pathogen to invade and multiply in the host is referred to as:
Infectivity
Toxigenicity
Pathogenicity
Virulence
Infectivity is the ability of the pathogen to invade and multiply in the host. The
other options do not accurately denote the pathogen’s ability to invade and
multiply in the host.
Question 20
2 / 2 pts

Loading page 10...

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?
Atrial septal defect (ASD)
Ventricular septal defect (VSD)
Patent ductus arteriosus (PDA)
Atrioventricular canal (AVC) defect
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 21
2 / 2 pts
Which cancer originates from connective tissue?
Osteogenic sarcoma
Basal cell carcinoma
Multiple myeloma
Adenocarcinoma
