A

A Correct. Untreated streptococcal tonsillitis and pharyngitis infections may lead to health problems such as scarlet fever, otitis media, and suppurative (pus forming) infections of surrounding tissues. More serious complications include acute glomerulonephritis, meningitis, and rheumatic fever.
B Incorrect. Encouraging the parents of a student who has a severe sore throat to take the child to the pediatrician, the nurse is not especially concerned about the child's school work.
C Incorrect. Encouraging the parents of a student who has a severe sore throat to take the child to the pediatrician, the nurse is not first concerned about the risk of spreading to others.
D Incorrect. Encouraging the parents of a student who has a severe sore throat to take the child to the pediatrician, the nurse is concerned about more serious health issues than anemia, weight loss, or lethargy.

Answer to Question 2

C

Feedback
A Incorrect. In fetal circulation, most blood will not bypass the fetal lungs via the inferior vena cava, instead most of the blood from the placenta enters the inferior vena cava on the way directly to the heart, thus bypassing the lungs.
B Incorrect. In fetal circulation, most blood will not bypass the fetal lungs via the ductus venosus; 60 of the blood from the placenta passes through the ductus venosus directly into the inferior vena cava.
C Correct. In fetal circulation, most blood will bypass the fetal lungs via the foramen ovale, an opening between the right and left atria of the fetal heart.
D Incorrect. In fetal circulation, most blood will not bypass the fetal lungs via the ductus arteriosus, however, a large amount of blood from the placenta travels through the ductus arteriosus (channel between the main pulmonary artery and the aorta).
