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.

The World Health Organization (WHO) defines grade 1 (overweight) as a BMI of:

30 to 39.9
40 to 50.9
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.
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
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
Research has shown a link between cancer and which sexually transmitted disease?
Syphilis
Gonorrhea
Human papillomavirus
Pelvic inflammatory disease
When renin is released, it is capable of which action?
Inactivation of autoregulation
Direct activation of angiotensin II
Direct release of antidiuretic hormone (ADH)
Formation of angiotensin I
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
What is the primary cause of the symptoms of polycythemia vera?
Decreased erythrocyte count
Destruction of erythrocytes
Increased blood viscosity
Neurologic involvement
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
Children with phenylketonuria (PKU) are unable to synthesize:
Essential amino acid, phenylalanine, to tyrosine
Renin, erythropoietin, and antidiuretic hormone
Aldosterone, cortisol, and androgens
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.

20%
25%
33%
50%
