The nurse should know that once human immunodeficiency virus (HIV) enters the body, seroconversion to HIV positivity usually occurs within:
6 to 10 days
6 to 12 weeks
6 months
10 to 14 weeks
The Correct Answer is B
Choice A reason: This is too short of a time frame for seroconversion to occur. Seroconversion is the process of developing antibodies to HIV, which can be detected by a blood test. It usually takes several weeks for the immune system to produce enough antibodies to be measurable.
Choice B reason: This is the typical time frame for seroconversion to occur. Most people will develop antibodies to HIV within 6 to 12 weeks after exposure. However, some people may take longer, up to 6 months or more.
Choice C reason: This is the upper limit of the time frame for seroconversion to occur. Some people may have a delayed antibody response to HIV, especially if they have a weakened immune system or take antiretroviral drugs. Therefore, it is recommended to repeat the HIV test after 6 months of exposure to confirm the diagnosis.
Choice D reason: This is an arbitrary time frame that does not reflect the average or the range of seroconversion. It is neither too short nor too long, but it is not accurate.

Correct Answer is C
Explanation
Choice A reason: Infection is not a common cause of IUGR, as most infections do not cross the placenta and affect the fetal growth. However, some infections such as cytomegalovirus, rubella, or toxoplasmosis can cause congenital anomalies and IUGR.
Choice B reason: Previous preterm birth is not a direct cause of IUGR, as it does not affect the current pregnancy. However, it may indicate an underlying maternal or fetal condition that could increase the risk of IUGR, such as cervical incompetence, placental abruption, or preeclampsia.
Choice C reason: Utero-placental insufficiency is the most common cause of IUGR, as it reduces the blood flow and oxygen delivery to the fetus. It can result from maternal factors such as hypertension, diabetes, smoking, or drug abuse, or from placental factors such as placenta previa, placental infarction, or cord compression.
Choice D reason: Chronic hypertension is a risk factor for IUGR, as it can lead to utero-placental insufficiency and fetal hypoxia. However, it is not the only cause of IUGR, as other factors can also affect the placental function and fetal growth.
