NR 507 FINAL EXAMS – QUESTIONS AND ANSWERS –SET 1
QUESTION 1
1/1 pts
Tissue damage caused by the deposition of circulating immune
... [Show More] 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).
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.

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.
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.
Cytokines are thought to cause fevers by stimulating the synthesis of which chemical
mediator?
Question 4
2 / 2 pts
Question 5
2 / 2 pts
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.
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).
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.
Question 6

IncorrectQuestion 7

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.
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.
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)
Question 8
2 / 2 pts
Question 9
2 / 2 pts
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 over circulation. The presentations of the other congenital heart defects are
not consistent with the described the symptoms.
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 [Show Less]
